This document provides an overview of asexual reproduction methods in animals. It begins with learning objectives and defines terms like binary fission, budding, and regeneration. It then explains how asexual reproduction occurs specifically in amoebas, hydra, and planaria. In amoebas, binary fission results in two identical daughter cells when the parent cell divides into two equal halves. Hydra reproduces through budding, where new hydra grow out from bulges on the parent and later detach. Planaria regenerate lost body parts. The document concludes with recapping questions and answers as well as providing additional reference material and video links.

The document discusses the different modes of reproduction in organisms. It describes asexual reproduction methods like vegetative reproduction, fission, budding, and regeneration. Potatoes and Protococcus are used as examples. Sexual reproduction requires two parents and produces offspring with unique gene combinations. Flower structure and reproduction in plants is demonstrated using gumamela. Both asexual and sexual reproduction ensure the continuity of life.
Reproduction-and-Development (1).pdf
The document discusses reproduction and development in plants and animals. It begins by defining reproduction and the two types: sexual reproduction which requires fertilization, and asexual reproduction which does not. Sexual reproduction results in offspring with genetic material from both parents. The document then discusses the process of fertilization and the three types of internal fertilization in animals. It provides examples to illustrate each type. Finally, it notes that some plants use water to facilitate fertilization through the transfer of sperm to egg.
03 characteristics of non vascular
This document provides information about non-vascular plants. It includes activities to identify non-vascular plants like seaweed and ferns. It describes that non-vascular plants lack vascular tissues to transport water and nutrients and have simple structures like algae, moss, and liverworts that reproduce using spores. It discusses that most non-vascular plants reproduce through fertilization between sperm and egg that form spores, while liverworts release balls of cells that grow into new plants.
Biology Lesson 3.4
1. Seeds contain an embryo which includes the plumule, radicle, hypocotyl, and one or two cotyledons that provide nutrients.
2. A seed also has a protective seed coat and may contain endosperm that stores additional food.
3. Germination occurs when a seed absorbs water, softens its coat, and the root and shoot emerge from the soil using energy from the cotyledons or endosperm. Factors like moisture, oxygen, temperature, and soil quality affect germination.
The life cycle of a butterfly
The document summarizes the four stages of a butterfly's life cycle:
1. Egg Stage - Female butterflies lay eggs on leaves which later serve as food for larvae.
2. Larva Stage - The eggs hatch into caterpillars which molt and eat leaves as they grow.
3. Pupa Stage - The caterpillar forms a hardened chrysalis and its body transforms into a liquid allowing wings and legs to form.
4. Adult Stage - A fully formed adult butterfly emerges from the chrysalis and is reproductive and mobile, undergoing courtship, mating, and egg-laying.

synapomorphies. : a character or attribute that is shared by at least two scientific categorizations
and is gotten through advancement from a typical genealogical shape.
7. Why is the development of seeds considered to be a major advance in the evolution of plants?
The development of the seed plants speaks to a noteworthy progress over the more primitive
Bryophytes and greeneries. In plants and greeneries, single- celled, haploid spores are the
essential means for attacking new living spaces. Spores have almost no sustenance stockpiling
and once sprouted can\'t endure extraordinary changes in natural conditions. Additionally, both
greeneries and greeneries require water for preparation while seed plants depend on air streams
and bugs. The seed plants can finish their life cycle completely on dry land, the length of
satisfactory soil dampness from the roots is accessible. Preparation happens inside defensive
tissues of the sporophyte (called integuments) and requires no outside water. Seed- bearing plants
create megaspores (expansive spores) in megasporangia that form into ovules and, at
development, deliver seed. They likewise deliver microspores (little spores) in microsporangia
that form into dust grains (male gametophytes) that convey the sperm to the female structures to
fulfill fertilization. Fertilization must go before preparation..
Life cycle of honey bees
The life cycle of honey bees consists of four stages: egg, larva, pupa, and adult. Eggs are laid by the queen bee and can be fertilized or unfertilized. Fertilized eggs become worker bees or queen bees, while unfertilized eggs become male drones. Larvae emerge from eggs and develop through four molting stages before forming a pupa. Inside the sealed pupa case, the larvae undergoes metamorphosis to emerge as adult bees. The life cycle takes longest for queen bees and shortest for worker bees.

Unit 4 The reproduction function
This document discusses reproduction in plants and animals. It covers asexual reproduction methods like budding and fragmentation as well as sexual reproduction involving gametes and fertilization. In plants, sexual reproduction can involve alternation of generations where spores form a gametophyte that produces gametes. Flowering plants use pollination and development of seeds and fruits. Animal reproduction is mostly sexual, involving gamete formation, internal or external fertilization, and embryonic and post-embryonic development. Some animals undergo metamorphosis during indirect development.

Sexual and asexual reproduction are compared. Sexual reproduction involves two parents and produces offspring with genetic variation, while asexual reproduction involves one parent and produces genetically identical offspring. Both involve forming new individuals but sexual reproduction results from fertilization of an egg by sperm and involves the formation of gametes, while asexual reproduction does not. The key differences are summarized using a Venn diagram.

Class 10 - Reproduction.pptx
There are two main types of reproduction - asexual and sexual. Asexual reproduction involves mitosis and produces offspring that are genetically identical to the parent. It is common in single-celled and simple organisms. Sexual reproduction involves meiosis and the fusion of male and female gametes, producing offspring that are not identical to the parents. It plays an important role in evolution and is seen in more complex multicellular organisms. Some examples of asexual reproduction discussed include binary fission, budding, regeneration and vegetative propagation using various plant structures like roots, stems and leaves. Sexual reproduction and the formation of gametes via meiosis is also summarized.

Unit 4 The reproduction function
This document discusses reproduction in plants and animals. It covers asexual reproduction methods like budding and fragmentation as well as sexual reproduction involving gametes and fertilization. In plants, sexual reproduction can involve alternation of generations where spores form a gametophyte that produces gametes. Flowering plants use pollination and development of seeds and fruits. Animal reproduction is mostly sexual, involving gamete formation, internal or external fertilization, and embryonic and post-embryonic development. Some animals undergo metamorphosis during indirect development.
The life cycle of a butterfly
The document outlines the four stages of a butterfly's life cycle: (1) Egg Stage, where the female butterfly lays eggs on leaves; (2) Larva Stage, where caterpillars hatch from eggs and molt as they eat leaves; (3) Pupa Stage, where caterpillars form hard chrysalises and undergo transformation; and (4) Adult Stage, where fully-formed butterflies emerge from chrysalises. The document also proposes using a PowerPoint presentation to teach students about this life cycle, followed by decoding and encoding activities to reinforce understanding.
ANIMAL REPRDUCTION.pptx
This document discusses animal reproduction, including the different types of reproduction (asexual and sexual) and how they work. It defines asexual reproduction as requiring only one parent and occurring through processes like fission, budding, fragmentation, and parthenogenesis. Sexual reproduction produces offspring with new combinations of genes and requires two parents. It notes some examples of organisms that exhibit different types of asexual and sexual reproduction, as well as sex determination methods like chromosomes and temperature dependence.
Protist and fungi lrmds
This document provides information about protists and fungi. It begins with an introduction to the module, which will cover protists in Lesson 1 and fungi in Lesson 2. Lesson 1 then discusses the different types of protists, including plant-like protists like algae and animal-like protists like amoebas. It explains how protists obtain food, move, and reproduce. Protists play important ecological roles but some can also harm humans and other organisms.

Here are the key steps to making a terrarium:
1. Choose a container such as a glass jar or plastic container with a lid. The container should be large enough to accommodate the plants and animals you want to include.
2. Add a drainage layer using small rocks, gravel, or charcoal to allow excess water to drain.
3. Add a soil layer using a soil suitable for the plants you've chosen. The soil should retain enough moisture but not become soggy.
4. Plant your plants and position decor such as sticks, stones, or moss. Choose plants that are suitable for low-light indoor conditions.
5. Add springtails or isopods to help break down
SCIENCE 7 - Q2W5 Slides.pdf
Sexual and asexual reproduction are compared. Sexual reproduction involves two parents and produces offspring with genetic variation, while asexual reproduction involves one parent and produces genetically identical offspring. Both involve forming new individuals but sexual reproduction results from fertilization of an egg by sperm and involves the formation of gametes, while asexual reproduction does not. The key differences are summarized using a Venn diagram.
EARTHLIFE-SCIENCE-Q2-WEEK-3-edited.pdf
The document describes the different ways that animals reproduce, including asexual and sexual reproduction. Asexual reproduction methods like fission, fragmentation, and budding produce offspring that are genetically identical to the parent without fertilization. Sexual reproduction requires fertilization of an egg by sperm and produces genetically variable offspring. It then explains various sexual reproduction methods such as external fertilization in frogs and internal fertilization processes like oviparity, ovoviviparity, and viviparity.

Class 10 - Reproduction.pptx
There are two main types of reproduction - asexual and sexual. Asexual reproduction involves mitosis and produces offspring that are genetically identical to the parent. It is common in single-celled and simple organisms. Sexual reproduction involves meiosis and the fusion of male and female gametes, producing offspring that are not identical to the parents. It plays an important role in evolution and is seen in more complex multicellular organisms. Some examples of asexual reproduction discussed include binary fission, budding, regeneration and vegetative propagation using various plant structures like roots, stems and leaves. Sexual reproduction and the formation of gametes via meiosis is also summarized.

hematic appreciation test is a psychological assessment tool used to measure an individual's appreciation and understanding of specific themes or topics. This test helps to evaluate an individual's ability to connect different ideas and concepts within a given theme, as well as their overall comprehension and interpretation skills. The results of the test can provide valuable insights into an individual's cognitive abilities, creativity, and critical thinking skillsPhenomics assisted breeding in crop improvement
As the population is increasing and will reach about 9 billion upto 2050. Also due to climate change, it is difficult to meet the food requirement of such a large population. Facing the challenges presented by resource shortages, climate
change, and increasing global population, crop yield and quality need to be improved in a sustainable way over the coming decades. Genetic improvement by breeding is the best way to increase crop productivity. With the rapid progression of functional
genomics, an increasing number of crop genomes have been sequenced and dozens of genes influencing key agronomic traits have been identified. However, current genome sequence information has not been adequately exploited for understanding
the complex characteristics of multiple gene, owing to a lack of crop phenotypic data. Efficient, automatic, and accurate technologies and platforms that can capture phenotypic data that can
be linked to genomics information for crop improvement at all growth stages have become as important as genotyping. Thus,
high-throughput phenotyping has become the major bottleneck restricting crop breeding. Plant phenomics has been defined as the high-throughput, accurate acquisition and analysis of multi-dimensional phenotypes
during crop growing stages at the organism level, including the cell, tissue, organ, individual plant, plot, and field levels. With the rapid development of novel sensors, imaging technology,
and analysis methods, numerous infrastructure platforms have been developed for phenotyping.

The debris of the ‘last major merger’ is dynamically young
The Milky Way’s (MW) inner stellar halo contains an [Fe/H]-rich component with highly eccentric orbits, often referred to as the
‘last major merger.’ Hypotheses for the origin of this component include Gaia-Sausage/Enceladus (GSE), where the progenitor
collided with the MW proto-disc 8–11 Gyr ago, and the Virgo Radial Merger (VRM), where the progenitor collided with the
MW disc within the last 3 Gyr. These two scenarios make different predictions about observable structure in local phase space,
because the morphology of debris depends on how long it has had to phase mix. The recently identified phase-space folds in Gaia
DR3 have positive caustic velocities, making them fundamentally different than the phase-mixed chevrons found in simulations
at late times. Roughly 20 per cent of the stars in the prograde local stellar halo are associated with the observed caustics. Based
on a simple phase-mixing model, the observed number of caustics are consistent with a merger that occurred 1–2 Gyr ago.
We also compare the observed phase-space distribution to FIRE-2 Latte simulations of GSE-like mergers, using a quantitative
measurement of phase mixing (2D causticality). The observed local phase-space distribution best matches the simulated data
1–2 Gyr after collision, and certainly not later than 3 Gyr. This is further evidence that the progenitor of the ‘last major merger’
did not collide with the MW proto-disc at early times, as is thought for the GSE, but instead collided with the MW disc within
the last few Gyr, consistent with the body of work surrounding the VRM.
Immersive Learning That Works: Research Grounding and Paths Forward
We will metaverse into the essence of immersive learning, into its three dimensions and conceptual models. This approach encompasses elements from teaching methodologies to social involvement, through organizational concerns and technologies. Challenging the perception of learning as knowledge transfer, we introduce a 'Uses, Practices & Strategies' model operationalized by the 'Immersive Learning Brain' and ‘Immersion Cube’ frameworks. This approach offers a comprehensive guide through the intricacies of immersive educational experiences and spotlighting research frontiers, along the immersion dimensions of system, narrative, and agency. Our discourse extends to stakeholders beyond the academic sphere, addressing the interests of technologists, instructional designers, and policymakers. We span various contexts, from formal education to organizational transformation to the new horizon of an AI-pervasive society. This keynote aims to unite the iLRN community in a collaborative journey towards a future where immersive learning research and practice coalesce, paving the way for innovative educational research and practice landscapes.

Unlocking the mysteries of reproduction: Exploring fecundity and gonadosomati...
The pygmy halfbeak Dermogenys colletei, is known for its viviparous nature, this presents an intriguing case of relatively low fecundity, raising questions about potential compensatory reproductive strategies employed by this species. Our study delves into the examination of fecundity and the Gonadosomatic Index (GSI) in the Pygmy Halfbeak, D. colletei (Meisner, 2001), an intriguing viviparous fish indigenous to Sarawak, Borneo. We hypothesize that the Pygmy halfbeak, D. colletei, may exhibit unique reproductive adaptations to offset its low fecundity, thus enhancing its survival and fitness. To address this, we conducted a comprehensive study utilizing 28 mature female specimens of D. colletei, carefully measuring fecundity and GSI to shed light on the reproductive adaptations of this species. Our findings reveal that D. colletei indeed exhibits low fecundity, with a mean of 16.76 ± 2.01, and a mean GSI of 12.83 ± 1.27, providing crucial insights into the reproductive mechanisms at play in this species. These results underscore the existence of unique reproductive strategies in D. colletei, enabling its adaptation and persistence in Borneo's diverse aquatic ecosystems, and call for further ecological research to elucidate these mechanisms. This study lends to a better understanding of viviparous fish in Borneo and contributes to the broader field of aquatic ecology, enhancing our knowledge of species adaptations to unique ecological challenges.
