1. Briefly discuss five criteria used to classify an organism as a multicelled animal? Solution 1). An organism with more than one cell in their structure is known as a multi-cellular organism. The following are the characteristics of multi-cellular organisms. The number of cells are more than one All animals are eukaryotic, they contain membrane bound organelles The organism must consume or feed on the other organisms (plants/animals) to obtain the organic compounds for survival. Means, they must be heterotrophs. Most of the animals are motile at least any stage during their life time They contain complex tissue structure with specialized functions. Many animals undergo sexual reproduction..

3. A plant breeder crosses an inbred soybean cultivar with herbicide tolerance (recessive allele) and susceptibility to a fungal pathogen (dominant allele) to an inbred soybean cultivar that is susceptible to herbicides (dominant allele) but is resistant to the fungal pathogen (recessive allele). The plant breeder generates F2 individuals and evaluates these individuals for herbicide tolerance and resistance to the fungal pathogen. The plant breeder generates thousands of F2 individuals which he inbreeds to generate purelines. The plant breeder finds that almost every plant that has herbicide tolerance is susceptible to the pathogen. What term is used to describe this phenomenon? A few of the F2 individuals described in question 3 are both herbicide tolerant and resistant to the fungal pathogen. What likely happened to the DNA in these plants in order for this to occur? Solution The phenomenon produced can be termed as epistatis where herbicide tolerance (hh, recessive allele) and susceptibility to a fungal pathogen (F(F/f),dominant allele) interact to show a mixed Dominant recessive epistasis i.e The F along with h masked the susceptible to herbicides (H,dominant allele) but is resistant to the fungal pathogen (ff, recessive allele). Therefore, most of the offspings of F2 generation were showing herbicide tolerance is susceptible to the pathogen F masked the effect of H . The plans with ff only showed both herbicide tolerant and resistant to the fungal pathogen.The DNA of these plants expressed the protein needed to express the reistant to fungal pathogen in absence of F..

A mirror faces a cliff located some distance away. Mounted on the cliff is a second mirror, directly opposite the first mirror and facing toward it. A gun is fired very close to the first mirror. The speed of sound is 343 m/s. How many times does the flash of the gunshot travel the round- trip distance between the mirrors before the echo of the gunshot is heard Solution lets assume that echo is heard after t time. distance covered: by light = 3*10^8 * t by sound = 343*t So, number of trips = 3*10^8/343 = 8.75*10^5.

Why is it important to identify Classes early in the Unified Process methodology? Solution it is also known as software development process which the development is done incrementally in step by step manner =>classe plays main role in the unified process,because unified process uses object oreinted techonology for analysis and desing of the software architecture.but before doing this he want build classes according to the client requirement in the architecture design. if we do analysis and design with proper define of classes the whole architecture may get in to trouble.

Which of the following is true about replication? The lagging strand is synthesized in a continuous fashion and the leading strand is not Helicase unwinds RNA Primases lay down the primers on the lagging strand Topoisomerase unwinds DNA Solution The only correct statement among the four in the given question is \'Topoisomerase unwinds DNA\'. Explanation for others are; leading strand is synthesized in continuous fashion whereas lagging strand is not, helicase unwinds DNA (which is double stranded) not the RNA (which is single stranded), primases lay down the primers on both, the leading as well as the lagging strands..

Which is a common trait among all land plants? Vascular tissues transport water and nutrients, and provide support Seeds facilitate survival and dispersal of the species Flowers facilitate cross-pollination The embryo is protected within maternal tissues The haploid phase of the life cycle is the dominant phase Flowers facilitate cross-pollination The embryo is protected within maternal tissues The haploid phase of the life cycle is the dominant phase Solution First we see common traits of land plants and then see listed traits in details one by one: 1. Ability to withstand desiccation. Extant land plants have a cuticle and guard cells. 2. Ability to withstand the effects of more intense radiation, particularly DNA-damaging radiation. Extant land plants have several compounds in their vacuoles that absorb UV. Since the vacuole of a plant occupies most of a mature cell, this helps protect the DNA in other organelles. 3. Ability to protect their spores from desiccation. Early land plants have spores that are encased in a sporopollenin wall. Sporopollenin is a very resistant polymer, resistant to UV and almost everything including desiccation, squashing, etc. To remove sporopollenin from spores, one boils them in a mixture of acetic and hydrochloric acid. 4. Ability to move solutions from the ground to portions of the plant that are not in contact with the ground, and from the photosynthetic portions of the plant to non-photosynthetic portions. Some land plants do this better than others. 5. Ability to support themselves. Aquatic plants float; terrestrial plants cannot do so. Most terrestrial plants have lignin in some of their conducting cells. There is some debate as to whether this was selected for by the advantages of growing tall or the need to protect against embolism in the conducting cells. Since both are important, it seems most realistic to accept that both contributed to the success of plants with the ability to manufacture lignin, the tracheophytes or vascular plants. 6. Ability to acquire the carbon dioxide required for photosynthesis from the atmosphere. This ability is associated with stomatal cells, specialized cells that surround openings (stomates) in the outer cell layer of land plants. Now we see Options given one by one: Vascular tissues transport water and nutrients, and provide support Transport of Water and Minerals: The xylem tissue transports water and minerals. It consists of interconnected vessels and tracheids organized into continuous conducting tubes stretching from the roots to the leaves. These tubes carry water and minerals to all parts of the plant. Plants absorb water from the soil through the root and transport it to the stem, leaves and flowers. Roots have root hairs that are unicellular, thin-walled outgrowths of the epiblema (skin of the root). The root hairs are in close contact with the thin film of water surrounding the soil particles. There are mineral salts such as nitrates, chlorides, sulphates, phos.

what role(s) played by the Equatorial Segment Protein 1 (ESP1) during fertilization. Solution The structure of a spermatozoa consists of three parts. They are, Acrosome is the elongated head region of the sperm containing 2/3rd of the nucleus. The enzymes present in the acrosome are essential for the penetration of a sperm into a secondary oocyte (egg). The acrosomal layer necessary for the fusion and penetration into the oocyte is deficient in mice lacking Equatorial Segment Protein 1 (ESP1). This indicates that ESP1 is necessary for the development of \"fusion-competent sperm.\".

What does it mean if a human female oocyte is no longer arrested in metaphase II of meiosis? Solution Answer: Primary oocytes forms prenatally and remain suspended in prophase of meiosis I until it reaches puberty. An oocyte completes meiosis I as its follicle matures resulting in a secondary oocyte and the first polar body. After ovulation, each oocyte continues to meiosis II metaphase. Meiosis II is completed only if fertilization occurs. This results in a fertilized mature ovum and the second polar body. Thus, the human female oocyte is arrested in metaphase II until fertilization by a sperm takes place..
