The answer is D as an electron is given off (which is a beta particle) and an electron is so small in weight/size (1/1840) that it is not counted when the mass number is calculated, instead the neutrons and protons are used
Also the atomic number is only dependant on the number of protons as this identifies the element as no two elements can have the same number of protons but can have the same number of electrons (e..g isotopes). So nothind is affected so it has to be D
If this question has the same set of choices like the previous ones, the answer would e letter d. all of the above.
here are the choices:
a) more wastes must leave the cell
b) more molecules must move through the membrane
c) distances from the cell membrane to various organelles are greater
<span>d) all the above</span>
Answer:
Monosaccharides are simple sugars with a basic formula Cⁿ (H2O)ⁿ. They are classified according to the number of carbon atoms they contain: tetroses (4), pentoses (5) and hexoses (6). There are also mosaccharides with 3 carbon atoms, for example the Dihydroxyacetone.
Explanation:
Monosaccharides have to be aldehydes (-CHO) or ketones (-COO) with more than one alcohol function, which will be located in different carbons.
Answer:
tertiary structure
Interactions among the amino acid side chains within a single protein molecule determine the protein's tertiary structure. Tertiary structure is the most important of the structural levels in determining, for example, the enzymatic activity of a protein.

Answer:
The correct answer is option A, that is, keratin.
Explanation:
Keratin refers to a protein that belongs to one of the families of fibrous structural proteins. It is the essential structural substance that forms nails, hair, horns, feathers, external layer of the skin, and hooves. It is the protein, which safeguards epithelial cells from stress or destruction. Keratin is tremendously insoluble in organic solvents and water.
