Why are sex-linked traits more common in males than in females?
a.All alleles on the X chromosome are dominant.
b.All alleles on the Y chromosome are recessive.
c.A recessive allele on the X chromosome will always produce the trait in a male.
d.Any allele on the Y chromosome will be codominant with the matching allele on the X chromosome
Answer:A
Explanation:
Sex-linked traits are more common in males than in females because all alleles on the X chromosome are dominant.
What do you mean by sex-linked traits?Sex linked describes the sex-specific patterns of inheritance and presentation when a gene mutation is present on a sex chromosome rather than a non-sex chromosome. In humans, these are termed X-linked recessive, X-linked dominant and Y-linked.
And in humans this is the X or the Y chromosomes. And so some of the more familiar sex-linked traits are hemophilia, red-green color blindness, congenital night blindness.
Sex-linked traits are characteristics that are determined by genes located on the sex chromosomes. Inheritance patterns for these traits can differ for males and females, since the X and Y chromosomes differ.

The answer is that a job of the skeletal system is to protect organs. Hope this helps! :)
Explanation:
The job of the skeletal system is to protect organs, provide support for the body, facilitate movement, produce blood cells, and store and release minerals and fat.
What is the function of a skeletal system?The skeletal system is the framework of the body, consisting of bones, cartilage, and other connective tissues. It provides a strong and stable structure for the body and protects vital organs such as the brain, heart, and lungs. The skeletal system also enables movement, as it works with muscles to allow for locomotion and other bodily functions. Additionally, the skeletal system produces blood cells, stores minerals, and helps regulate the body's pH balance.
The skeletal system provides the body with structural support, and protection of internal organs, and helps in movement by serving as a site for muscle attachment. It also functions in producing blood cells, storing minerals such as calcium and phosphorus, and facilitating communication between different parts of the body through hormones.
Therefore, the correct answer is C) to protect organs.

Why must the bonds of these molecules be broken before anything else happens?
Answer:
Synthesis releases energy because the molecules bond to form a stable configuration and therefore give up energy. The bonded molecules have a lower energy level than free molecules and are held in the new bond.
Explanation:
Chemical reactions make and break the chemical bonds between molecules, resulting in new materials as the products of the chemical reaction. Chemical reactions can occur spontaneously or require an outside trigger such as an input of energy. Breaking chemical bonds absorbs energy, while making new bonds releases energy, with the overall chemical reaction being endothermic or exothermic.
Because molecules must link together to establish a stable structure, they lose energy during synthesis. The newly formed bond holds the bonded molecules, which are at a lower energy level than free molecules.
Why the bonds of molecules are broken?Because molecules must link together to establish a stable structure, they lose energy during synthesis. The newly formed bond holds the bonded molecules, which are at a lower energy level than free molecules.
Chemical reactions create and destroy the chemical bonds that hold molecules together, creating new materials as their end product. Chemical reactions can start on their own or need an outside trigger, like an energy input. Chemical reactions can be endothermic or exothermic in that breaking chemical bonds takes energy while creating new ones releases it.

Explanation:
Rainforests around the world are being cleared at an alarming rate to make room for new communities, agriculture, mining, and roads, and to provide lumber for construction and furniture. How might the destruction of rainforests affect the balance of gases in Earth's atmosphere?
This question is incomplete because the options are missing; here is the missing section:
How might the destruction of rainforests affect the balance of gases in Earth's atmosphere?
by increasing carbon dioxide and decreasing oxygen
by increasing carbon dioxide and increasing oxygen
by decreasing carbon dioxide and increasing oxygen
by decreasing carbon dioxide and decreasing oxygen
The answer to this question is by increasing carbon dioxide and decreasing oxygen.
Explanation:
Rainforests have a vital role on Earth because these regulate the levels of oxygen vs carbon dioxide. This is because plants including trees, grasses, shrubs, etc. require carbon dioxide as part of the photosynthesis process, and they release oxygen at the end of the process. In this way, rainforests reduce the amount of carbon dioxide and increase oxygen.
In this context, deforestation or the destruction of rainforest for mining, roads, etc. implies there are fewer plants, and therefore, less carbon dioxide is being used and less oxygen is released. This causes an increase in carbon dioxide and a decrease in oxygen.

Why does a carrot in a hypertonic solution of salt water float compared to a carrot in a hypotonic solution of salt water (which sinks)?
Answer:
Cell membranes are permeable to water, and in the absence of a solute on either side of a membrane, water will move one way as easily as it moves the other. If the outside of the membrane contains a solute, such as salt, the solution correspondingly contains fewer water molecules. To restore equilibrium -- the same number of water molecules on both sides of the membrane -- water flows from inside, and the cell shrinks. On the other hand, if the concentration of solute inside the membrane is greater, water flows into the cell and swells it. This is called osmosis.The turgidity, or stiffness, of a carrot depends on the water content of its cells. When the cells are full of water, they grow large and are packed closely together, making the carrot turgid. Conversely, when the cells lose water, they shrink and the carrot shrivels. That's what happens when you put a carrot in salty water and leave it there. When the concentration of water molecules inside the cells matches that outside, the carrot stops shriveling, and when you remove it from the water and taste it, it has a stronger flavor because it contains less water
Most mutations that cause cancer occur within body cells, and body cell mutations are not inherited. If cancer is not inherited, why does cancer statically appear to run in families?
Family members have a similar genetic make-up that may make them predisposed to cancer.
Family members are exposed to similar environmental conditions.
Family members have a widely varied genetic make-up that can be affected by specific mutagens.
Family members share the contagious mutagens that can be passed by close exposure.
Answer:
Family members have a similar genetic make-up that may make them predisposed to cancer.
Explanation:
Variation in certain genes can increase the risk of developing certain cancers. This is why certain cancers run in families. There are lots of examples where the risk factor is small, but in some cases, the risk factor is very large.
For example, mutations in BRCA1 are very highly linked to the risk of breast cancer. As a result, many women with mutations in this gene opt to get a mastectomy to reduce their chances of developing breast cancer.

A patient suffering from breast cancer chooses to undergo surgery. Doctors remove the breast where the tumor is. However, doctors say that there is no guarantee the cancer will not come back. What makes it so hard to cure cancer? Check all that apply. A single diseased cell can multiply into a new tumor. Cancer cells can travel through the blood and spread into new areas. There is no research being done on possible cures. Many cancer cells multiply so fast that new tumors can form.
Answer:
The correct answers are: A single diseased cell can multiply into a new tumor; cancer cells can travel through the blood and spread into new areas; many cancer cells multiply so fast that new tumors can form.
Explanation:
Cancer is the term that groups different conditions that have all one thing in common: there's an abnormal cell growth that can potentially irradiate to other parts of the body.
A single diseased cell can develop a tumor, because this abnormal cell has the capacity to replicate so fast and, of course, transmit its abnormality to every other cell that it generates.
These abnormalities occur because there is some sort of damage in the DNA of a cell, which most of the time is detected by the body and eliminated - but when it's not, the cell quickly multiplies itself and generates a tumor. The difference between a benign tumor and cancer is that cancer can spread through the body and a benign tumor can not.
Cancer is very dangerous and potentially fatal if not treated fast because it can travel through the bloodstream or the lymphatic system and invade other organs, causing metastasis.
There's a lot of research being done on how to cure cancer, but the disparities in every different type of cancer make finding the solution much harder. Nowadays, depending on the type of cancer and the stage where the cancer is, this condition can be treated with radiotherapy, chemotherapy, or surgery.
