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.

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.

The Rest and Recovery Principle.
The Use It or Lose It Principle.
Answer:
The Overload Principle - The basic principle that specifies that you perform physical activity in greater than normal amounts (overload) to get to an improvement in physical fitness health benefits.
The F.I.T.T. Principle - FITT (frequency, intensity, time, and type) is one way to remember the general guidelines for what should be included in a fitness plan.
The Specificity Principle - Principle that states the body will adapt to the specific demands that are placed on it.
The Rest and Recovery Principle - suggests that rest and recovery from the stress of exercise must take place in proportionate amounts to avoid too much stress
The Use It or Lose It Principle - meaning that one must continually engage in and practice an ability or risk losing it.
