Answer:
A mutation can alter the structure/function of a particular protein, thereby also altering the phenotype resulting from this new variant
Explanation:
A mutation can be defined as a genetic change in the genome of an organism. Some mutations are capable of modifying the expression and/or structure of the proteins, while other mutations (known as silent mutations) have no effect on the resulting proteins. When mutations occur within the gene region encoding a protein (i.e., exons), they are potentially capable of producing a faulty protein. For example, a mutation can alter the Open Reading Frame (ORF) of the resulting protein, thereby inactivating it. The mutations that alter the structure and/or function of the protein can also alter the resulting phenotype associated with the expression of this protein. For example, a mutation within a gene that encodes a key enzyme can potentially alter the binding site of the protein, so the resulting mutated enzyme cannot bind to the substrate anymore. In consequence, this mutation alters the phenotype of the individual who is not more able to carry out the metabolic reaction catalyzed by the faulty enzyme.
The helper T-cells are the part of the immune system that stimulates B cell multiplication. hope this helps! :)

Answer:
Small nonpolar molecules, such as O2(oxygen) and CO2(carbon dioxide)
Explanation:
Oxygen and carbon dioxide are soluble in the lipid bilayer (mostly because oxygen and carbon dioxide are lipids) and therefore can readily cross cell membranes. Small uncharged polar molecules, such as H2O(water), also can diffuse through membranes but will have a hard time doing so, but larger uncharged polar molecules, such as glucose(carbohydrates), cannot.
Hope this helps! Brainliest?? Anyways have a great day my loves <3
Answer: Option 1, 2,3, 4, 5 are all correct.
Explanation:
The spleen is an organ that is located in the left quadrants of the abdomen and it's extend from the 9th to the 11th ribs. It is like the clenched of a fist in shape and it is found between the fundus of the stomach and diaphragm, found underneath the diaphragm. It is a soft mass of lymphatic tissue which is part of the lymphatic system.
Spleen help to filter and remove old blood cells. It function in cell mediated and humoral immune responses.
