The steps involved in herpes simplex virus lytic cycle are: attachment on the epithelial cells. Penetration of the herpes virus inside the cell. Uncontrolled replication of the virus takes place. The virion gets assembled and finally released by bursting the cell.
Explanation:
The lytic infection of the virus results in breaking of bacterial or any cell after its replication.The lytic infection is phage infecting bacteria and getting replicated and bursts the cell of bacteria.
There are 5 stages in which lytic infection takes place in any virus like herpes simplex virus:
Attachment on bacterial cell wall:
penetration of virus
biosynthesis
maturation
release of virions
During the infection the HSV genes are expressed in the epithelial cells and get replicated resulting in sores and irritations as in genitals.
the cycle is generally 18- 20 hours long.
I would say C. Why I say this is because fur is used to keep an animal warm. If the animal no longer needs to be kept warm, then it no longer needs the thick fur.
Answer:
Microglial cell
Explanation:
The microglial cells are macrophages that are in the central nervous system (brain and spinal cord) protecting it. This cells will phagocytize damaged neurons as when a person has Alzheimer as well as agents that can cause a potential damage to the central nervous system such as the meningitis virus. When the Microglial cells phagocytize they absorb the damaged neuron or antigen and then they destroy it.
Females have two copies of the X chromosome, while males have one X and one Y chromosome. The 22 autosomes are numbered by size. The other two chromosomes, X and Y, are the sex chromosomes. This picture of the human chromosomes lined up in pairs is called a karyotype.
Of the 23 pairs of chromosomes, the first 22 pairs are called "autosomes." The final pair is called the "sex chromosomes." Sex chromosomes determine an individual's sex: females have two X chromosomes (XX), and males have an X and a Y chromosome (XY).
