Protozoa
Protozoans are unicellular eukaryotes that lack cell walls and motility is provided by cilia, flagella, or pseudopodia. They ingest food and can reproduce asexually through binary fission or budding or sexually through conjugation or gamete fusion. Plasmodium, a protozoan parasite, causes the disease malaria in humans. It has a complex life cycle alternating between mosquito and human hosts. In humans it evades the immune system by hiding in the liver and red blood cells, where it consumes hemoglobin and reproduces asexually.
Chapter 11 protozoa
1. Protozoa are a diverse assemblage of unicellular eukaryotes that lack cell walls and have at least one motile life stage. They include free-living, mutualistic, commensal, and parasitic forms that reproduce asexually through mitosis or sexually through conjugation/syngamy.
2. Important protozoan phyla include Euglenozoa, which includes the disease-causing trypanosomes, and Axostylata, which have a stiffening rod. Sarcodina, including the amoeba Amoeba proteus, move using pseudopods and feed through phagocytosis. Foraminifera and radiolarians have shells and have
phycology-algal classification, thallus organization, reproduction
The document discusses phycology, the study of algae. It covers the classification of algae based on characteristics like pigmentation and thallus organization. Some key classifications discussed include Harvey's 1836 system of dividing algae into green, brown and red classes, and Fritsch's 1935 classification that organized algae into 11 classes. The document also summarizes the distribution of algae in aquatic environments, their thallus organization as unicellular or multicellular, and their methods of reproduction including vegetative, asexual through spores, and sexual.
Classification of algae
This document classifies algae into two categories - prokaryota and eukaryota. Prokaryota algae have an absence of a well-organized nucleus and lack membrane-bound organelles, while eukaryota algae have a well-defined nucleus surrounded by a nuclear envelope and contain membrane-bound organelles. The document then lists 12 phyla of eukaryotic algae: Euglenophyta, Chlorophyta, Charophyta, Parsinophyta, Xanthophyta, Haptophyta, Dinophyta, Bacillariophyta, Chrysophyta, Phaeophyta, Rhodophyta, and Cryptophyta.
Kiingdom protists 2
The document discusses different types of protists. It describes four phyla of protozoans: Sarcodina, Mastigophora, Ciliophora, and Sporozoa. It also discusses three phyla of algae - Chlorophyta (green algae), Rhodophyta (red algae), and Phaeophyta (brown algae). Finally, it summarizes the characteristics of slime molds, including their vegetative phase, reproduction, and examples like Physarum and Dictyostelium.
Kingdom monera
Prokaryotes are single-celled organisms that are the oldest and most abundant organisms on Earth. They are smaller and simpler than eukaryotic cells as they lack membrane-bound organelles and nuclei. Prokaryotes include bacteria and archaea, and can live in nearly every habitat on Earth including some of the most extreme environments. They play important roles in ecosystems as producers, consumers, and decomposers.

Kingdom protista
Protists have more complex structures and functions than bacteria, including specialized organelles. They can be classified as plantlike, funguslike, or animal-like. Plantlike protists include algae and phytoplankton, which are photosynthetic and provide food for aquatic animals. Funguslike protists are saprophytic and derive energy from breaking down dead organic matter. Animal-like protists, also called protozoans, are heterotrophic and include zooflagellates, sarcodina, sporozoa, and ciliates.
Why do we find life on Earth?
The Earth is unique in that it has an average temperature of 15o C, an atmosphere containing oxygen, and contains water, making it the only known place in the universe that can support life.
Earthquakes
Earthquakes are caused by the sudden release of energy from the Earth's crust as tectonic plates shift and rocks break. They generate seismic waves that travel from the hypocenter or focus point at the epicenter, and can cause damage to buildings, landslides, and tsunamis depending on their magnitude as measured on the Richter scale. The worst quakes result from plates rubbing past each other along faults like the one off the coast of California.
Speed
Here are 3 examples for you to try:
1. Measure how far you can hop in 10 seconds. Divide the distance by 10 to calculate your average hopping speed in m/s.
2. Time how long it takes you to hop 5m and divide 5 by the time to calculate your hopping speed.
3. Try hopping or walking backwards for 10 seconds and calculate your average speed the same way. See how it compares to moving forward.
Let me know if you need help with the calculations or have any other questions! Measuring your own movement speed can be a fun way to apply what you've learned.
Tsunamis
Tsunamis are caused when a large section of the sea floor suddenly moves and displaces a massive amount of water, creating low amplitude long wavelength waves that gain destructive force as they reach shallow shorelines where the sea floor causes wavelengths to shorten and amplitudes to increase.
Bacteria
Bacteria are unicellular prokaryotes that can be heterotrophs or autotrophs. They have a cell membrane, cell wall, cytoplasm, and genetic material but lack organelles. Bacteria can be classified based on their shape as cocci, bacilli, vibrios, or spirilla. They reproduce through binary fission and can form spores during sporulation. Environmental conditions influence their growth and reproduction rates.
Acceleration
This document discusses acceleration and deceleration, defining acceleration as an increase in speed and deceleration as a decrease in speed. It provides the formula for calculating acceleration as the change in velocity divided by the time taken, and gives an example calculation of the acceleration of a Bugatti Veyron going from 0 to 1609.36 meters in 25.9 seconds, which works out to 62.14 m/s^2.
Boundaries
There are three types of plate boundaries: divergent boundaries where plates move apart, convergent boundaries where plates push together as they move towards each other, and transform boundaries where plates slide past one another in a sideways motion. Plates can move in different ways depending on the type of boundary, with divergent boundaries creating new crust as the plates spread apart, convergent boundaries resulting in one plate moving under the other in a process called subduction, and transform boundaries causing the plates to rub horizontally alongside one another.
Quizz scientific method
This document contains a series of multiple choice science questions and their correct answers from 5th grade science tests. The questions cover topics like scientific processes, experiments, observations, graphs, charts and more. This appears to be a compilation of released test questions to help teach scientific investigation and reasoning skills to 5th graders.
Fungi
Fungi come in various forms including molds, mushrooms, and yeasts. They feed through absorption of nutrients from living or dead matter like plants, animals, or other fungi. Fungi live in damp environments and some are beneficial by aiding in processes like bread making, while others are harmful parasites that can cause diseases in plants and animals. Fungi are classified as unicellular yeasts, multicellular molds that can be parasites or break down organic matter, or multicellular mushrooms and toadstools that can be edible or poisonous.
Earth's internal energy
The interior of the Earth is hot due to heat from the Earth's formation over 4 billion years ago from the gravitational compression of matter and frequent meteorite impacts, as well as ongoing heat from the radioactive decay of elements in the Earth's core. As the Earth cooled, denser materials like iron sank to the center forming the inner and outer cores, while less dense rocks rose to form the mantle and crust. Today, the Earth's inner core reaches temperatures over 6,000 degrees Celsius due to pressure and heat increasing with depth below the surface.
Cicle of matter and flow of energy
This document outlines the flow of energy and cycle of matter through ecosystems. Energy from the sun is used by producers like plants and some bacteria and transferred to primary, secondary, and tertiary consumers. Matter cycles as organisms decompose and inorganic matter is reused by producers.

- Species diversity is highest in the middle of the gradient, and lower at the extremes. This suggests that intermediate levels of the environmental factor(s) represented by the gradient allow the most species to coexist.
- Diversity declines towards both ends of the gradient. This implies that as conditions become more extreme in either direction, fewer species are able to tolerate those conditions.
- The declines in diversity at the ends could be due to species being excluded by conditions becoming too harsh. It could also reflect competitive exclusion if only a few highly specialized species can survive at the environmental extremes.
- In summary, the hump-shaped pattern is
Protista pcc revised
- Protists are a diverse group of eukaryotic organisms, most of which are microscopic. They are classified into three main groups: animal-like protists which are heterotrophic and motile, plant-like protists which are photosynthetic, and fungi-like protists which are decomposers.
- Protists exhibit characteristics of both unicellular and multicellular organisms. They can reproduce both sexually through meiosis and gamete formation, and asexually through binary fission. Many important human diseases are caused by parasitic protists, such as malaria caused by Plasmodium and African sleeping sickness caused by Trypanosoma.
DOMAIN-KINGDOM-PHYLUM.pptx
The document discusses the three domains of life - Archaea, Bacteria, and Eukarya. Within these domains are six kingdoms - Archaebacteria, Eubacteria, Protista, Fungi, Plantae, and Animalia. The kingdoms are classified based on cell type, number of cells, and feeding type. Details are provided on the defining characteristics of each kingdom.

This document summarizes the key points of the five kingdom classification system proposed by R.H. Whittaker which includes Monera, Protista, Fungi, Plantae and Animalia. It provides details on the characteristics of each kingdom, including examples of organisms that fall under each kingdom. The kingdoms are differentiated based on factors like cell structure, nutrition, reproduction and phylogenetic relationships. Viruses and lichens are also briefly discussed.
Marine invertebrates
Marine invertebrates include sponges, cnidarians, flatworms, and other phyla. Sponges are simple multicellular organisms that filter feed using choanocytes. Cnidarians like jellyfish, corals, and sea anemones have radial symmetry and use nematocytes to capture prey. Flatworms are acoelomates with a gastrovascular cavity, and include free-living and parasitic forms.

Chapter_3_Kingdom_Plantae.pptx
Kingdom Plantae is divided into subkingdoms Cryptogams and Phanerogams. Cryptogams are spore-producing plants with concealed reproductive structures, while Phanerogams are seed-producing plants with visible reproductive structures. Phanerogams are further divided into gymnosperms and angiosperms. Gymnosperms include conifers and cycads which bear naked seeds, while angiosperms are flowering plants whose seeds are enclosed in fruits.
Protists
Protists are eukaryotic organisms that are more closely related to animals, plants and fungi than bacteria. They can be unicellular or multicellular without specialized tissues. Protists have a variety of means of locomotion including cilia, flagella and pseudopodia. They are found in aquatic ecosystems worldwide and some are pathogens of plants and animals. Protists exhibit both sexual and asexual reproduction and have been present on Earth since the Precambrian era.

Embryonic development
This document describes three different types of reproduction: viviparous reproduction where embryos develop inside the female body, such as in mammals; oviparous reproduction where embryos develop inside eggs outside the female body, as seen in birds and reptiles; and ovoviparous reproduction where embryos develop in eggs that are retained inside the female body, like in some fish, snakes and lizards.
Anaya interaction function process
The document describes the interaction function process in 3 steps: 1) A bird's visual (light) and auditory (chirping) signals are captured by a cat's sensory organs. 2) The sensory organs send this information to the cat's central nervous system. 3) The central nervous system processes the information and sends a signal to the cat's muscles to respond by trying to catch the bird.
Anaya interaction in plants
Plants react to stimuli in three main ways: tropisms, nastic movements, and changes in vital processes. Tropisms are directional growth responses to stimuli like light, gravity, water, and touch. Nastic movements involve rapid reversible movements of plant parts in response to light or touch. Changes in vital processes alter processes like flowering, fruiting, and leaf drop in response to seasonal factors such as temperature, daylight hours, and length of night.

Mutation Testing for Task-Oriented Chatbots
Conversational agents, or chatbots, are increasingly used to access all sorts of services using natural language. While open-domain chatbots - like ChatGPT - can converse on any topic, task-oriented chatbots - the focus of this paper - are designed for specific tasks, like booking a flight, obtaining customer support, or setting an appointment. Like any other software, task-oriented chatbots need to be properly tested, usually by defining and executing test scenarios (i.e., sequences of user-chatbot interactions). However, there is currently a lack of methods to quantify the completeness and strength of such test scenarios, which can lead to low-quality tests, and hence to buggy chatbots.
To fill this gap, we propose adapting mutation testing (MuT) for task-oriented chatbots. To this end, we introduce a set of mutation operators that emulate faults in chatbot designs, an architecture that enables MuT on chatbots built using heterogeneous technologies, and a practical realisation as an Eclipse plugin. Moreover, we evaluate the applicability, effectiveness and efficiency of our approach on open-source chatbots, with promising results.
