The answer is; D
These cells are called plasmodesmata. They are significant in the symplastic flow (meaning through the cytoplasm) of water and other molecules in the plant. A membrane called desmotubule runs along the pores of adjacent plasmodesmata. These cells are also significant in the communication between cells.
A = Phosphate group
B = Deoxyribose sugar
C = Nitrogenous base

Homologous chromosomes pair up and exchange segments of DNA.
Option A
<h3><u>Explanation:</u></h3>
Crossing over is an event of Prophase 1 of meiosis 1. It occurs in the zygotene phase of prophase 1. Here the homologous chromosome pairs get very close together and gets packed within protein coat. The enzymes randomly cut the DNA segments from both chromosomes at same loci and exchange them with each other. This results in the exchange of genes between the two chromosomes. This is how the variation comes to place between offsprings of the same individuals. The crossing over results to form X shaped intersections between homologous pair of chromosomes which is called as chaismata. This phase occurs in pachytene phase and is visible in diplotene phase when the protein coat dissolves.
Answer: Option B.
Homeostasis.
Explanation:
Homeostasis is the ability of an individual to maintain it's internal state despite changes in the outside environment.
Homeostasis is a process to stop bleeding and keep blood in a damaged vessels. Homeostasis is the first stage of wound healing, which is a process that transform liquid blood to gel like. It is also called coagulation.
