Answer:
Facilitated diffusion involves transport protein
Explanation:
Homologous chromosome pairs are separated
Meiosis 1 refers to the initial stage of meiosis where one parent cell divides into two daughter cells. This stage is where homologous pairs of chromosomes will segregate and separate from each other and move into the two daughter cells which result in the division of the total chromosomal number by half.
<h3>What happens during Meiosis 1 ?</h3>
Meiosis I ends when the chromosomes of each homologous pair arrive at opposing poles of the cell.
- The microtubules disintegrate, and a new nuclear membrane forms around each haploid set of chromosomes.
- The chromosomes uncoil, forming chromatin again, and cytokinesis occurs, forming two non-identical daughter cells.

Answer:
Option (A) and (D).
Explanation:
Esophagus may be defined the long tube like structure that connect the throat with the stomach. The partially digested food from the buccal cavity to the stomach is pass down through the esophagus.
The mucosa of the esophagus contains the thick layer of the nonkeratinized squamnous epithelium. The smooth muscles are present in some layers only. The two layer of the muscle that are superior to the one third of the muscularis are the skeletal muscle.
Thus, the correct answer is option (A) and (D).
Answer:b
Explanation:
It will only be found in some cells because when a mutation is formed it will most likely not be able to spread
