20 chromosomes.
A cell with 40 chromosomes going through meiosis will result in individual haploid cells with 20 chromosomes each.
After the first nuclear and cellular division in meiosis, each cell will already have 20 chromosomes each, since homologous chromosomes are separated at Anaphase I in Meiosis I. After the second nuclear and cellular division in meiosis, each cell will have 20 chromosomes as well, since the sister chromatids of each of the 20 chromosomes are separated during Anaphase II in Meiosis II.
Hope this helps! :)
Darker colors absorb and retain warmth than warm tones. As a result, plants in the tundra have dark-colored leaves, hairy and clumped and stems to help them absorb solar heat faster and stay warm for longer periods of time. So it could be tundra ecosystem according to the given scenario.

Darker colors absorb and retain warmth than warm tones. As a result, plants in the tundra have dark-colored leaves, hairy and clumped and stems to help them absorb solar heat faster and stay warm for longer periods of time.
Thus, the correct ecosystem for the given condition is tundra.

Answer:
Vector changes with geography.
Explanation:
Vectors of disease are changing with the changing in the geographic location because different vectors survives in different environment so due to change in geography, vectors of a disease also change. Vectors refers to organisms that is responsible for carrying infectious bacteria or viruses that causes certain diseases in animals, plants and humans. Different vectors are present in different geography due to different climatic condition that forbit one vector to survive in all environments.
