C. Insulating the body

Insulating the body is not a function of a protein.

Lipids are macromolecules which provide insulation.
<span>A macromolecule is a large molecule. There are four groups of macromolecules: carbohydrates, proteins, nucleic acids and lipids. Lipids consist of glycerol and fatty acids and are constructed from fats, oils, waxes, phospholipids and steroids. A lipid's function is to insulate the body and provide warmth in cold conditions. It can be concluded that a person with very little body fat gets very cold easily and a person with a lot of body fat gets very warm very quickly.

Insulating the body is not the function of proteins. It is one of the main functions of fats. Therefore, option (C) is correct.

Further Explanation:

The biomolecules perform various important functions in the body of an organism. Proteins, fats, nucleic acid, and carbohydrates are the main classes of biomolecules. These molecules have carbon (C), oxygen (O), hydrogen (H), and nitrogen (N) as their major components. Proteins are the complex and large biomolecules made up of amino acids (monomer units). Different proteins have different sequence of amino acids in their structure and these amino acids are linked to one another by peptide bonds.

The amino acid sequence (primary structure) defines the three-dimensional shape of the proteins and its function as well. The proteins carry out most of the work in the cell that includes repair and structure maintenance, energy, transportation and storage of molecules, enzymes, hormones, and antibodies. The proteins provide support and structure to the cell. They help in the movement of the body also. Actin is an example of structural protein.

Some proteins (like ferritin) binds to the small molecules and ions (like iron) and help in their storage in the body. Antibodies are the small protein molecules that protect the body against foreign particles. Enzymes are the proteins that take part in several biochemical reactions taking place in the body. The proteins help in the breakdown of food and thus, provide energy to the body. The example of messenger proteins that help in signal transmission and coordinating biological activities is hormone.

Fat (lipid) is another class of biomolecules that plays a vital role in insulating the body against shock and maintaining healthy skin and body temperature. The fats help in storing energy and signalling too.

A microbiologist has identified a new gram-negative pathogen that causes liver disease in rats. She suspects that the bacterium’

valina [46]

<h2>Koch's postulates </h2>

Explanation:

Koch formulated a set of criteria that could be used to identify the pathogen responsible for a specific disease and these criteria came to be known as Koch’s postulates:

The organism must be regularly associated with the disease and its characteristic lesions

The organism must be isolated from the diseased host and grown in culture

The disease must be reproduced when a pure culture of the organism is introduced into a healthy, susceptible host

The same organism must be re-isolated from the experimentally infected host

In the given hypothesis , Koch's postulates could be used as:

1) identify pathogen associated with disease 2) isolate or purify pathogen 3) test subject gets pathogen 4) same disease/ causes liver disease or not

In the following experiment, what is the independent variable? Dr. Honeydew would like to test the effect of chlorine on Beaker'

Contact [7]

Answer: Chlorine

Explanation:

An independent variable can be define as changable variable, which can be used to determine it's impact over the other variable(s) in the experiment. Dependent variable cannot be changed manually instead changes occur in the independent variable is because of impact of independent variable.

In this experiment, chlorine is the independent variable. The effect of which can be observed on the hair color, which is a dependent variable.
