Answer:
The letter B is the right answer.
Explanation:
The main objective of the hardin and Weinberg equilibrium is to determine how the allelic frequencies change within a population.
In 1908, Godfrey H. Hardy (1877-1947) and the German physician, Wilhem Weinberg, proposed that if no evolutionary factors act on a given population, the frequencies of their alleles would remain unchanged for several generations. This proposal became known as Hardy-Weinberg's Law (or theorem) or principle of gene balance.
According to this law, the necessary conditions for a population to reach equilibrium are:
a) The population must be large, so that all possible intersections occur.
b) The population must be panmatic (from the Greek pan, all, and from the Latin miscere, mix), that is, the crossings must be carried out randomly, without preconditions.
Within these conditions, without mutation, migration or selection, there will be a genetic balance. Over the generations, genes will not change.

Kepler would be the answer
Peppered moth stimulation is an experimental setup that show the behavior of moth in relation to their environment. The objective of the setup is to stimulate changes in moth population as a result of pollution and predation.
Peppered moth stimulation relates to the survival of the fittest because the moth with the most adaptive ability will be able to survive despite the negative forces in the environment. The bright colored moth was able to survive the pollution in the environment and retains its colour while the black coloured moth change its colour to black due to the pollution int the environment.
Answer:
The correct answer will be- Blast cells
Explanation:
Blasts are the poorly differentiated cells which act as precursors to the circulating mature blood cells. The blast cells act as precursors to neutrophils, monocytes, erythrocytes and lymphocytes.
The blast cells are usually found in high number in circulating blood as compared to bone marrow. These cells can be characterized as they show a single round nucleus, smooth chromatin with more than one nucleoli and high N: C ratio.
Thus, Blast cell is the correct answer.
