Answer: c. when she ends the diet she regains additional body fat.

Explanation:

Obesity can be defined as a genetic disorder in which the body obtains and retains too much amount of body fat. It is different from being overweight.

Obesity happens when the person obtains more amount of calories in the food then actually burned through work or exercise. Obesity increases the risk factor for arthritis, stroke and cancer.

Here, in the given situation, ending up diet is the likely cause of regaining weight again. As the unstable diet is likely to add more calories then actually utilized by the body and will be retained as fat.

Resethelp 1. Structure describes the alpha-helices and beta-sheets that are formed by hydrogen bonding between backbone atoms lo
ss7ja [257]

1. Answer;

-secondary structure;

Explanation;

Protein secondary structure refers to regular, repeated patterns of folding of the protein backbone. The two most common folding patterns are the alpha helix and the beta sheet. In an alpha helix, the polypeptide backbone coils around an imaginary helix axis in clockwise direction. In the beta sheet secondary structure, the polypeptide backbone is nearly fully extended. The R-groups are alternately pointed above and then below the extended backbone.

2. Answer;

- Quaternary structure

Explanation;

-Many proteins are formed from more than one polypeptide chain. The Quaternary structure describes the way in which the different subunits are packed together to form the overall structure of the protein. For example, the human hemoglobin molecule shown below is made of four subunits.

3. Answer;

-Tertiary structure

Explanation;

Tertiary structure refers to the overall folding of the entire polypeptide chain into a specific 3D shape. The tertiary structure of enzymes is often a compact, globular shape.

The tertiary structure is the structure at which polypeptide chains become functional. At this level, every protein has a specific three-dimensional shape and presents functional groups on its outer surface, allowing it to interact with other molecules, and giving it its unique function.

4. Answer;

Primary structure

Explanation;

-It is the simplest level of protein structure and is simply a sequence of amino acids in a polypeptide chain. For example, the hormone insulin has two polypeptide chains, A and B. Each chain has its own set of amino acids, assembled in a particular order. For instance, the sequence of the A chain starts with glycine at the N-terminus and ends with asparagine at the C-terminus, and is different from the sequence of the B chain.

How are animal like and plant like protests are similar and different
QveST [7]

Answer:The main way animal-like protists differ from plant-like protists is in the way they get energy. Animal-like protists are heterotrophs. ... Plant-like protists, on the other hand, are autotrophs. They can make their own energy from the sun or other sources just as plants can.

Why is it important to know a person blood type before a blood transfusion?
lord [1]
Different types of blood contact different kinds of antigens and antibodies. For example, Type A blood has A antigens and B antibodies, antibodies being the thing that fights B antigens. Type B blood has B antigens and A antibodies. So if someone with type B gets transfused with Type A blood, the person's antibodies will attack the new blood.

If it were not for the __________, osteocytes in the outer lamellae of an osteon would not be able to transport their wastes to
lora16 [44]

Answer:

canaliculi

Explanation:

According to my research on studies by various medical professionals, I can say that based on the information provided within the question the term being mentioned is called the canaliculi. This is a small channel that link together the lacunae and whose main function is routing nutrients to osteocytes and expelling waste products.

I hope this answered your question. If you have any more questions feel free to ask away at Brainly.
