Answer:

Explanation:

The four elements been referred to here are hydrogen, oxygen, carbon and nitrogen.

These four elements constitute the majority of the human body because of a combination of factors. Although, some of these factors are the major reasons, for instance the human body is made up of cells which are the basic structures of life. The cell consists of over 70% of water (which is made of hydrogen and oxygen). Also, oxygen is inhaled through the process of respiration which combines with other molecules (such as haemoglobin to form oxyhaemoglobin) in the human body. These among others make oxygen the most abundant element in the human body.

Naturally occurring organisms usually have a high concentration of organic molecules (molecules made of majorly carbon and hydrogen). This makes the human body have a high percentage (after oxygen) of carbon and hydrogen. Also, carbohydrates (which are later converted to glucose) form a large part of our diet and are stored in the body as glycogen (causing the body to have a high amount of carbon and hydrogen atoms).

Nitrogen is an essential part/element found in amino acids which are building blocks of protein. Proteins are involved in several metabolic activities in the body; this makes the abundance of nitrogen the fourth (one of the four) most common element in the body. It should be noted that amino acids also have carbon and hydrogen elements also.

The combination of the factors above among some other factors make the human body comprise mainly of these four elements

The analysis of total microbial genomes in an environment is called _________________________and the total microbial genomes in

Levart [38]

The analysis of total microbial genomes in an environment is called metagenomics and the total microbial genomes in an environment (or the total microbial community itself) is called a microbiome.

<h3><u>Explanation:</u></h3>

The study that is associated with the genetic materials that are obtained directly form the sample in an environment refers to the term Meta genomics or ecogenomics or community genomics. It can be considered as the process through which the meta genome is produced.

The genetic material of the microbes such as fungi, bacteria, viruses and protozoa refers to microbiome. These microbes lives inside the body of humans. The weight may range upto 5 pounds for these microbiomes. Micorbiomes are the total number of micro genomes that are present in the environment.

If a person has a diet high in saturated fats, _________ molecules can carry cholesterol from the liver to cells and to the arte

leonid [27]

Answer:

If a person has a diet high in saturated fats, LDL cholesterol molecules can carry cholesterol from the liver to cells and to the arterial walls whereas HDL cholesterol transports cholesterol from the cells to the liver where it is converted to bile salts which can modulate cardiovascular function.

Explanation:

Cholesterol is a lipid generated in the liver that is used to make hormones and vitamin D, but can also be ingested when eating fats.

Cholesterol can be divided into two types: LDL (low-density lipoprotein) and HDL (high-density lipoprotein).

LDL is commonly known as the "bad cholesterol" and is responsible for the deposit of cholesterol in the walls of arteries, which generates atherosclerosis and can potentially lead to strokes or heart attacks because it occludes the vessels and makes it impossible for the blood to advance.

HDL is also called "good cholesterol" because it takes the cholesterol from the cells to the liver where it'll serve a good cause, instead of blocking the arteries.

To reduce the amount of LDL, it's best to limit the consumption of fatty meats, dairy products and other saturated fats. Foods with a good amount of HDL are those with unsaturated fats, like fish, nuts and seeds.
