Answer:
c. Two sister chromatids did not separate into the proper daughter cells during anaphase.
Explanation:
The observed cell is undergoing mitosis which does not include separation of homologous chromosomes. During anaphase of mitosis, two sister chromatids of each chromosome separate from each other. They move to opposite poles. This results in equal distribution of two complete sets of chromosomes to each daughter cell.
However, the failure of two sister chromatids of a chromosome during anaphase would lead to the formation of two abnormal daughter cells. One of the daughter cells would have one extra chromosome (2n+1) while the other would lack one chromosome from the diploid set (2n-1).
Answer:
Together
Explanation:
All of the organisms need each other to survive, all of the natural cycles are necessary to keep the Earth in balance.
When climbing a mountain, we can observe transitions in biological communities that are analogous to the changes in biomes at different latitudes.
Answer:
2,855 is the size of the colony of mosquitoes after 4 days.
Explanation:
The law of uninhibited growth is given as:
= Original amount
A = Amount after time t
k = Positive constant repressing the rate of growth
We are given with:
Original population of mosquitoes = 1000
Population of mosquitoes after 1 day =1300
t = 1 day
Population size of mosquitoes after 4 days
A =? , t = 4 days
A =2,855.36 ≈ 2,855 mosquitoes
2,855 is the size of the colony of mosquitoes after 4 days.
