Answer:

All of the above

Explanation:

Digestion or breakdown of food in our body can either be physical/mechanical or chemical/enzymatic. As rightly stated in this question, the manual breakdown of food by the teeth is not enough, chemical digestion must occur via the aid of proteinous substances called ENZYMES. Enzymes, which are secreted by certain organs in the body, do the following:

- They speed up the rate of chemical reactions by lowering the activation energy needed for the chemical process, allowing more productivity.

- Enzymes help break down various sugars that can then be absorbed e.g amylase helps break down starch, proteases break down proteins, lipases break down lipids etc.

Virtually all cells in the human body have the same DNA. What’s make some undifferentiated cells differentiated into brain cells
mariarad [96]

Answer:

Changes in gene expression

Explanation:

This phenomenon is the result of changes in gene expression. That means, how the information in the DNA is used by the cell. The genes that are active in the cells of the brain will be very different from the genes that are active in the cells of the bone marrow.

These patterns of gene expression are different for each cell, and dictate the identity of that cell. Gene expression patterns are controlled by a variety of factors in the cell that allow tissue-specific expression, such a transcription factors.

This can also be facilitated by another layer of regulation called epigenetics, which literally means "on top of" genetics, and refers to modifications of DNA (and the proteins around it), that can reflect and influence the activity of the genes within.

Some of the food in the protein group and dairy group are high in saturated fats and cholesterol. These raise which cholesterol
BigorU [14]

The food in the protein group and dairy group are high in saturated fats and cholesterol, it raise LDL in blood.

<h3>What is cholesterol?</h3>

Cholesterol is a waxy like substance synthesized from two sources such as liver and from animals like meat, poultry, diary product.

There are two types of cholesterol, one is bad called LDL cholesterol and second one is good called as HDL.

LDL narrow down the arteries by depositing fats in it, the condition known as atherosclerosis which leads to increase in risk for heart attack, stroke and peripheral artery disease.

On the other hand, HDL protect against heart attack and stroke

Third component called triglycerides are the common type of fat act as a reservoir of excess energy.

Hence, LDL is the correct answer.
