Answer:

Triglycerides

Explanation:

Triglycerides are a kind of fat, the most common type in the body. Triglycerides can come directly from foods, such as oils, butter, and other fats, and they can be created by a person’s body when that individual consumes more calories than his or her body needs as a way of storing those surplus calories.

The medical term for having elevated levels of triglycerides is hypertriglyceridemia.

In fasting laboratory tests, a normal triglyceride level is below 150 milligrams per deciliter (mg/dL).  High is considered 200 to 499 mg/dL. Very high is over 500 mg/dL.

High triglyceride levels can increase risk for heart disease, stroke, and nerve damage.

why do all organisms take in matter and rearrange atoms through chemical reactions to form molecules essential for life?
Tom [10]
Cause living things can not directly use most of matter which they found in nature. For example carbon, all organism use carbon in complex structure, that is in compound or macromolecule(glucose,fructose,amino acid). we can not directly earn ATP from C which we found in soil/other sources.

A memory B cell is kinda of how it sounds it has a memory of what your body has fought before such as a virus and can stimulate a response quicker then the first time you encountered it. 

If you lack memory B cells your body doesn't built up the same immune response when you come into contact with the virus again.

"Vaccination would prevent further disease" Incorrect, a vaccine lets you build up memory cells to combat the disease if you lack them you cannot build up a defense.
"Vaccination would not prevent further disease" Correct, a vaccine can be a dead version of a virus or parts of a virus that shows your body what to respond to quickly in the future. If you body cannot make memory b cells it wouldn't help to use a vaccine. Your body wouldn't keep a memory of it being bad.
"You would not produce antibodies" Even if your body does not remember a particular virus it does produce antibodies to combat it just not as quick or efficiantly as something it has come into contact with before and produced memory cells.
"You would over produce histamine" Incorrect, different process for that histamine.

Expressivity is the term used to describe the balanced genetic output from a hemizygous condition. True or False
dem82 [27]

Answer:

The statement is FALSE.

Explanation:

In genetics, expressivity refers to the amount of variation in a non binary phenotype across individuals, who are carrying a specific genotype. Scientists believed that variable expressivity is controlled by different factors such as environment, genetics and lifestyle choice. An example of expressivity is  a series of blue eye color that has different shades of blue. Thus, expressivity is not about balanced genetic output but varied genetic expression.
