Q2. Give a brief account of viruses with respect of thesolzucture and nature of genetic material. Also name 4common viral |
|
Answer» Answer: Viruses are sub-microscopic, infectious, nucleoprotein particles that can infect all living organisms. A virus consists of genetic material either in the form of RNA or DNA surrounded by a PROTEIN coat. Most of the viruses, infecting PLANTS, have single-stranded RNA as genetic material. On the other hand, the viruses infecting animals have single or double-stranded RNA or double-stranded DNA. Bacteriophages or viruses infecting bacteria mostly have double- stranded DNA. Their protein coat called as capsid is made up of capsomere subunits. These capsomeres are ARRANGED in HELICAL or polyhedral geometric forms. AIDS, smallpox, mumps, and influenza are some common examples of viral diseases. |

In a population with two alleles for a particular locus, B and b, the allelefrequency of B is 0.7. What would be the frequency of heterozygote ifthe population is in Hardy-Weinberg equilibrium?(a) 0.7 0.42 (c) 0.49 (d) 0.09 (e) 0.21 |
|
Answer» Answer: 0.42 Explanation: FREQUENCY of ALLELE P = 0.7 or 70%, Frequency of allele p = 0.3 or 30%. From Hardy-Weinberg equilibrium : (p^2 + 2pq + q^2) 2pq (Heterozygous genotype) = 2 x 0.7 x 0.3 = 0.42 or 42% |

3. what isthebasisdivisionofblood groups? Name the four typegroupsblood |
|
Answer» Answer: The ABO blood group The four different blood groups in the ABO SYSTEM are A, B, AB and O. A person’s blood group is determined by a pair of genes, ONE gene inherited from each parent. Each blood group is identified by its own set of molecules (CALLED antigens), which are located on the surface of red blood cells. When a person needs a blood transfusion, the donated blood must match the recipient’s blood or complications will OCCUR. |

Which character of pteridophytes is not similar to bryophytes1 . water requirement 2. dependence of sporophyte on gametophyte 3. heterospory 4. none of above |
|
Answer» Answer: Bryophytes are known as the amphibians of plant kingdom because they need water for fertilisation. The sperms of bryophytes are flagellated and REACH the eggs by means of swimming in water. On the other hand, pteridophytes do not need water for fertilisation. Bryophytes have gametophyte as dominant phase of life on which sporophyte is dependent whereas Pteridophytes have sporophyte as dominant phase but sporophyte is not dependent on gametophyte. Heterospory is the FORMATION of two types of spores which are different in size i.e. large spores and SMALL spores. Large spores are called megaspores while small spores are called microspores. Spores are FORMED by the sporophyte both in bryophytes and pteridophytes. Hence, option A is defines a character which is not same in bryophytes and pteridophytes. So, the correct answer is 'Water REQUIREMENT for fertilization'. |

Explain each of the following :A) diffusion happens faster when the tempreature rises .B)oxygen diffuses out of a plant leaf during daylight hours .C)water molecules can pass through visking tubing but starch molcules cannot D)an animal cell brusts if placed in pure water .E)if a plant is short of water its leaves lose their firemness and the plant wilts |
|
Answer» Answer: Temperature: Higher temperatures increase the energy and therefore the movement of the molecules, increasing the rate of diffusion. Lower temperatures decrease the energy of the molecules, thus decreasing the rate of diffusion.Therefore, net gaseous exchange during day time is, oxygen diffuses out and carbon DIOXIDE diffuses in. During night time no photosynthesis occurs in the leaves. Therefore, in the process of respiration oxygen diffuses into leaves from the air and carbon dioxide diffuses out in the air.When we put animal cells into pure, FRESH water (H2O) , water enters the cells as a RESULT of osmosis, and making the cell expand. ... Since animal cells do not have a cell wall, when too much of this water enters to make the concentration of water on both sides even, the animal cell may eventually burst, and die out.This continual flow of water and nutrients keeps the plant's cells firm, if the cells become short of water they lose firmness and the plant starts to WILT. We can demonstrate transpiration by placing white flowers in coloured water, the water travels up the stem to the petals which become coloured like the water. |
