The question is incomplete as it does not have the options which are:
I. only
I. and II. only
II. and III. only
I, II, and III.
Answer:
I, II, and III.
Explanation:
The mechanism of natural selection can be explained for the trait which is determined by one gene but the traits which can be determined by more than one gene like height (polygenic trait), the selection becomes very complex.
The natural selection can be explained by the phenotype produced in a population and that depends on the genes. The polygenic trait shows the variation in the population, therefore, it is impossible to predict only one mechanism and therefore all types of natural selection occurs on a population.
Thus, I, II, and III are correct.
Answer:
O
Explanation:
O having traits that enable the spices to adapt to the changed enviroment
Answer:
The specimen are placed in vacuum while examining the cells or living organisms. Also, the electron must penetrate inside of the cell and in such conditions, any living organism is not able to survive. Thus, this reason best explains the answer to why dead cells specimen must be used for Transmission electron microscopy.
