The process, which contribute to the pattern of animal diversity observed is EXTINCTION EFFECTS BOTH LOCALLY AND GLOBALLY.
Biodiversity refers to the varieties of plants and animals, which are obtainable in a particular ecosystem. A high level of biodiversity is always consider to be very important for any ecosystem. The reduction in diversity that was observed was due to mass extinction of some plants and animals. <span />
Answer:
<em>Nutrition and Growth.</em>
Explanation:
Nutrition: Nutrition is defined as the ability of living organisms to feed. The reason for feeding is to enable living things live and carry out life processes like growth, respiration and reproduction. While all green plants can manufacture their own food through a process called autotrophic or holophytic nutrition. all mamma can not manufacture their own food but depend on plant directly or indirectly for their food, hence this type of nutrition is called heterotrophic nutrition.
<em>Growth: </em>Growth is defined as an irreversible or permanent increase in size, dry mass or weight of an organism due to addition of living proton plasmic materials. The purpose of growth is to enable organisms to repair or replace damaged or old tissue in the body. The food eaten provides the basis for growth of organisms.
Answer:
Semi-conservative DNA replication:
The semi-conservative model of DNA replication explains that the newly synthesized daughter DNA molecule contains one newly synthesized strand and one parental strand. This model of replication is important and explains the biological significance of replication. The DNA unwinds in this mode of replication.
Conservative model of DNA replication:
The conservative model of DNA replication explains that the newly synthesized daughter DNA molecules has the one DNA helix of parent and the other DNA helix are entirely new. This model does not has a biological significance. The DNA is not unwinds in this mode of replication.
The semi-conservative mode of DNA replication is found in the living organism.
Answer:
transferring information from one source to another in the same language but a different format
Answer:
CD4 on the surface of helper T-cells.
Explanation:
MHC class II ( major histocompatibility complex) molecules are processed from the exogenous source. The presentation of antigen on cells are important for the adaptive immune response.
MHC class II interact with CD 4 present on the surface of T helper cells. This interaction is important for the generation of an immune response. Helper T cells can release cytokines and can perform phagocytosis.
Thus, the correct answer is option (C).
