White short-horned cattle and Black Angus cattle have been crossed to produce offspring with superior beef and rapid growth qualities. This process of choosing organisms with the most desirable traits for mating is known as

A. cloning
B. biodiversit
C. selective breeding
D. genetic engineering

The correct answer is option C, that is, selective breeding.

Explanation:

A procedure in which the development of novel organisms is done manually to obtain desirable features is known as artificial selection or selective breeding. In the process, the scientists or the breeders go for two parents exhibiting desired phenotypic characters and mate them to generate offspring comprising desired traits from both the parents.  

The process is used to generate better varieties of vegetables and fruits, bigger animals having more meat, and crops having desired characteristics. Thus, in the given question, where a black Angus cattle and a white short-horned cattle are mated to generate an offspring comprising better qualities of growth and more beef shows that the process of selective breeding is done.  

after a the power stroke, adp is released, but the cross-bridge formed is still in place. atp then binds to myosin, moving the myosin to its high-energy state, releasing the myosin head from the actin active site.
