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).
the insertion of a nucleotide into DNA would most likely cause a mutation.
Answer:
Option (A).
Explanation:
Facilitated diffusion may be defined as the process of movement of the particles from the region of higher concentration towards the region of lower concentration with the help of specific integral transmembrane protein.
Facilitated diffusion is a type of passive diffusion and solute particle down the concentration gradient. So this process doesn't require an ATP or any other energy source.
Thus, the mismatched pair is option (A).
They should ask the population of the people to know how much supply’s they need and what does everyone need hope this helps :)
Do you have a picture? as I’m unsure which elements need matching
