Answer: Meiosis is a process in which the number of chromosomes per cell is cut in half through the separation of homologous chromosomes in a diploid cell. Meiosis usually involves two distinct divisions, called meiosis I and meiosis II. By the end of meiosis II, the diploid cell becomes four haploid cells.
Explanation:
Yes, the planet obeys the Kepler's Second Law. It is because it moves at equal time of one month at the same distance.
Answer:
Option (A).
Explanation:
The muscle contains the different type of proteins that helps in the contraction of muscles and the movements of different body parts. The proteins are actin, myosin, nebulin and tropomyosin.
The binding of the troponin with the calcium result in the confrontational change. This twists the another protein tropomyosin. This helps in the exposure of the actin-myosin binding site. Later, the ATP acts as the main factor for the muscle contraction.
Thus, the correct answer is option (A).
Answer:
The question is incomplete but the complete question is attached in image format with options and the correct answer according to the data given in it is - option B. The optimum habitat for the golden-cheeked warbler population in 100 juniper trees per acre
.
Explanation:
The provided data with the question helps to establish that the population interaction between a golden-cheeked warbler and the juniper tree are interdependent. The population of the warbler is increased with the increase in the population of juniper tree up to 100 juniper trees per acre.
The further increase in the population of the juniper tree affects negatively and there is a decrease in the population of the warblers.
Thus, the correct answer is - option B. The optimum habitat for the golden-cheeked warbler population in 100 juniper trees per acre
