Which of the following are affected by the order of amino acids in a protein? Select all that apply.
irinina [24]
<h2>Answer:</h2>

The <u>structure and function</u> are affected by the amino acids order in a protein.

<h2>Explanation:</h2>

The succession of a protein is controlled by the DNA of the genes that encode the protein. An adjustment in the gene's DNA arrangement may prompt an adjustment in the amino acid grouping of the protein. In any event, changing only one amino acid in a protein's grouping can influence the protein's general structure and capacity.  

For example, a solitary amino acid change is related to sickle cell frailty, an acquired infection that influences red platelets. In sickle cell frailty, one of the polypeptide ties makes hemoglobin, the protein that conveys oxygen in the blood has a slight succession change. The glutamic acid that is regularly the 6th amino acid of the hemoglobin β chain is supplanted by a valine.

Andru [333]

Answer:

The correct answer is -

Independent variable - change in the concentration of carbon dioxide

Dependent variable - bubbles produced

Explanation:

The independent variable of an experiment or study is a variable that is subject to change or being manipulated during the study to find the response on the dependent variable. The concentration of carbon dioxide is here manipulated to find the change in the amount of bubble produced.

The dependent variable is a response that is carried out by the change or manipulation of the independent factor. In this case amount of bubbles is the dependent variable.

Thus, the correct answer is -

Independent variable - change in the concentration of carbon dioxide

Dependent variable - bubbles produced

zvonat [6]

Answer:

Independent variable: Planting depths of seeds

Dependent variable: plant height

Explanation:

Independent variable in an experiment is the variable that the experimenter changes or manipulates in order to bring about a measurable response. In this experiment involving the planting of radish seeds at varying depths, the DEPTH AT WHICH THE SEEDS ARE PLANTED is the independent variable.

Dependent variable is the variable that is measured in an experiment. It is the variable that responds to the changes made to the independent variable. In this experiment, the HEIGHT of the radish plants measured is the dependent variable.
