Answer:
Recombination occurs when two molecules of DNA exchange pieces of their genetic material with each other. One of the most notable examples of recombination takes place during meiosis (specifically, during prophase I), when homologous chromosomes line up in pairs and swap segments of DNA.
Answer:
B. Shortens
Explanation:
Myofibrils are components of the animal skeletal muscles that are made up of sacromeres. They perform the muscular contraction and relaxation via the sliding filament model.
To produce motion, A cross-bridge forms between actin and the myosin heads triggering shortening of the sacromere. This shortening of the sacromere results in the contraction of the muscle fibers, which the net effect can be seen to be a shortening of the fibers
Answer:
a) The change in the character of an organism relies upon the ability of the adaption on the base of the external change or the environment change, "An organism that is not able to adapt accordingly would not survive and eliminated from the population."
b) In the given case, Symmetric wings are far more suitable for the survivorship as it provides better flight than the organism with asymmetric wings, it is also given that there is 20% of the population have asymmetric wings.
After the storm which is selection pressure, there is the elimination of the entire bird population with asymmetrical wings from the ecosystem so the final frequency would be 100% of the entire population with symmetrical wings.
