Explanation:
1. If an embryo's cells carry a Y chromosome, its genes cause what
to develop
Explanation:
In the nucleus of each cell, the DNA molecule is packaged into thread-like structures called chromosomes.
Most human cells contain 23 pairs of chromosomes. One set of chromosomes comes from the mother, while the other comes from the father. The twenty third pair is called the sex chromosomes, while the rest of the 22 pairs are called autosomes.
Typically, biologically male individuals have one X and one Y chromosome (XY) while those who are biologically female have two X chromosomes. However, there are exceptions to this rule.
The sex chromosomes determine the sex of offspring. The father can contribute an X or a Y chromosome, while the mother always contributes an X.
The Y chromosome is one-third the size of the X chromosome and contains about 55 genes while the X chromosome has about 900 genes.
In genealogy, the male lineage is often traced using the Y chromosome because it is only passed down from the father.
All individuals carrying a Y chromosome are related through a single XY ancestor who (likely) lived around 300,000 years ago.
The Y chromosome contains a "male-determining gene," the SRY gene, that causes testes to form in the embryo and results in development of external and internal male genitalia. If there is a mutation in the SRY gene, the embryo will develop female genitalia despite having XY chromosomes.
Variation in the number of sex chromosomes in a cell is quite common. Some men have more than two sex chromosomes in all of their cells (the XXY variation is called the Klinefelter syndrome), and many men lose the Y chromosome from their cells as they age. Smoking may exacerbate this loss.
Some genes that were thought to be lost from the Y chromosome have actually relocated to other chromosomes.
Much of the Y chromosome is composed of repeating DNA segments. Specialized techniques are needed sequence and determine the arrangement of these highly similar segments.
Many health conditions are thought to be related to changes in genes expressed on the Y chromosome. This is currently an active area of research.
which hygiene claim is not supported by reserch
Answer:
Hand soap prevents disease better than antibacterial soap
Explanation:
Previous research has supported that regular cleaning of teeth could improve dental health of a person. It is advisable that we wash our hands after going to the toilet/latrines because hand washing could kill germs and bacteria that are invisible by our naked eyes thus prevent us from diseases. Dentists have advised that brushing with fluoride toothpaste helps to prevent cavities.

Explain the population distribution according to rural and urban areas.
Answer:
According to the United States Census Bureau, an urban area is a city with a population size of more than 2,500 people, and a rural area has a population of fewer than 2,500 people. This definition can be tricky because it does not include information about the size of the area or the density of the population.

Devon picked me up after school today in his dad’s car. It’s an antique from
the 1950s and doesn’t even have safety belts! Devon drives really fast, but
other than that he’s a good driver.
Health Risks:
Your Rewrite:
Answer:
The health risks include - fatal injuries by speeding and ejected due to the absence of seat belts.
Explanation:
As it is mentioned that car is an antique from the 1950s so there would be no legal obligation for not having and not wearing a seat belt. However, there is a risk present in speeding the car and it becomes riskier as there is no seat belt for the front seat or passenger seat.
Rewrite: It is found that there are 30 percent more likely to get ejected in a fatal crash die from their injuries so one should avoid driving fast especially if there is no sat belt and always seat belt if present.

Genital human papillomavirus (HPV) is the most common sexually transmitted infection. What, if any, treatment options exist for HPV, and what are the risks and complications of this type of infection? (1 point)
a
There is a vaccine that prevents contraction, but if someone is infected, the virus can develop into serious diseases including genital warts and cervical cancer.
b
There is a vaccine to treat a contracted infection, but if the infection is not cured, it can develop into genital cancer or infection to the brain, heart, or blood vessels.
c
There are no effective treatment options, but HPV usually goes away on its own; in rare cases where the infection does not go away, it spreads to cause heart disease or joint infection.
d
There is an antibiotic that can treat HPV if caught early; but if left untreated, it can spread to cause cervical cancer or infections in the brain or nervous system.
Answer:
a. There is a vaccine that prevents contraction, but if someone is infected, the virus can develop into serious diseases including genital warts and cervical cancer.
Explanation:
The Human Papillomavirus (HPV) is a common virus contracted through sexual intercourse. Some people are not aware that they actually have the virus while others may experience serious conditions of having cervical cancer. There is no cure for HPV once a person contracts it, but there's a vaccine to prevent contracting the virus. This vaccine is recommended to be given to girls starting age 9. It is followed by another dose 6-12 months after. Women older than 26 years old are no longer recommended to have this because they're most likely to have been exposed to many HPV already.

What happens when the negative feedback response to a stimulus
Answer:
A negative feedback loop is a reaction that causes a decrease in function. It occurs in response to some kind of stimulus. Often, it causes the output of a system to be lessened; so, the feedback tends to stabilize the system. This can be referred to as homeostasis, as in biology, or equilibrium, as in mechanics.

Hence the nurse should refuse to grant the request of the patient.
