Respond to the following based on your reading. 1. The testes are male reproductive organs that produce and store , which is the male gamete containing half of the DNA in somatic cells.
2. The typically 28-day process of egg release from the ovaries and, if fertilization does not occur, release from the body, is known as the cycle.
3. If two eggs are released and fertilized by two different sperm, then twins will occur.
4. If a hormone operates by entering a cell's nucleus and altering the expression of its DNA, then it is classified as a/n hormone.
5. Once sperm cells are mixed with seminal fluid to provide protection and nutrition, this mixture is known as .
6. The bulbourethral and glands play an important role in providing additional fluids to semen production.
7. The first phases of a new zygote's growth through mitosis occur in the .
8. The germ layer will eventually develop into the skin and nervous system.
9. A fetus growing in the uterus does not eat food or drink water. Instead, important nutrients, antibodies, and molecules pass from the mother through the .
10. Make a list, or write a short paragraph, that explains the major stages of pregnancy after fertilization, through childbirth. Provide as much detail as possible.

i believe the correct answer is the virus gets an envelope that contains host molecules when it leaves the host cell.

explanation:

during the bidding/release stage of a virus, it encapsulates itself with part of the membrane of the host cells in this case the cells of the monkey and is the reason as to why the scientist found the genetic material of the monkey on the viral cell surface.

further explanation

to understand this answer, we have to know the cycle a virus undergoes to replicate. a virus is basically a bunch of genetic material enclosed in a capsule and lacks any machinery or organelles to ensure their survival so they must enter a host cell in order to get the environment needed to survive. some viruses enter and lyse(destroy) the host cell after they have replicated and undergo the lytic cycle while some enter and leave the cell intact after replicating and these undergo a lysogenic cycle. to enter the cell, they undergo the first process called attachment by binding to specific receptors and co-receptors on the surface of the host cell. after attaching to the cell, they start the second phase called penetration where virus enters or is engulfed whole by the host cell through a process called endocytosis. it is the same process that a cell takes up materials it needs or pathogens around it. uncoating of the virus then happens after the virus has been engulfed and is the third stage. the virus then undergoes releasing of its genetic material in the host's matrix.   the materials then enter the nucleus and undergo biosynthesis by adding themselves in strands of rna being translated and then copies of the virus are produced in addition to the host genetic material. the material/newly formed viral material then undergoes assembly inside the host cell and form a capsule around them. the virus undergoes the last release/budding stage by binding to the host membrane and pushing outwards. in doing so when they tear away from the host membrane, they pick up the genetic material from the membrane of the host cell to form their envelope.
