Answer:
Genes are pieces of DNA (deoxyribonucleic acid) inside each cell that tell the cell what to do and when to grow and divide. Each gene is made up of a specific DNA sequence that contains the code (the instructions) to make a certain protein, each of which has a specific job or function in the body. Each human cell has about 25,000 genes.
Explanation
I already learned about genes, and this is what I learned
Two human examples of multiple-allele<span> genes are the gene of the ABO blood group system, and the human-leukocyte-associated antigen (HLA) genes. The ABO system in humans is controlled by three </span>alleles, usually referred to as IA, IB, and IO<span> (the "I" stands for isohaemagglutinin).</span>
Plasma membrane is the structure which covers up the uptaken molecule.
<h3><u>Explanation:</u></h3>
Uptaking of nutrients from the surrounding needs to be very appropriate for the cell to obtain nutrition, as well as to maintain cell immunity. In case of simpler molecules like glucose etc, the molecules are taken inside the cell by means of specific channels or transport proteins. In case of complex molecules, cells prefer to perform endocytosis - either phagocytosis for solid ones, and pinocytosis for liquid ones.
When the cell finds something which can be taken in, it projects a fold of cell membrane towards the liquid which surrounds part of the liquid, or fully. This cell membrane then presents a depression which covers up the liquid. Then the margins of the depression come closer and ultimately fuse, leaving the liquid inside the cell enclosed with a part of cell membrane. This then fuses with a primary lysozome to form a digestive vacoule, a secondary lysozome, a residual body, and ultimately gets excreted off the cell.
Soil is non-living because it does not need the basic units of life. Soil does not necessarily need water to survive, soil does not need food, soil does not need shelter, soil doesn’t even need air.
Insulin is the correct answer.
Hope ti helped!
