Answer: Proteins.
Explanation:
<u>Proteins are organic molecules made of amino acids</u> which are arranged in a linear chain and joined together through a peptide bond.
Membrane proteins are classified depending on their location:
- Integral membrane proteins are part of a cell membrane and can either penetrate the membrane or associate with one side of a membrane.
- Peripheral membrane proteins are transiently associated with the cell membrane.
They perform many important functions:
- Membrane receptor proteins: relay signals between the internal and external environments.
- Transport proteins: move molecules and ions across the membrane.
- Membrane enzymes: transform a molecule into another form
- Cell adhesion molecules: allow cells to identify each other.
Sex linked traits can only be held on the X chromosomes, so males only need one while females need two. Since the daughter has it, it must mean the mother is a carrier and has one normal X chromosome and another with the recessive trait (c).
The mass number is the combination of neutrons and protons within the nucleus. Thus, this atom has a total of 19 protons and neutrons combined. The atomic number is only the number of protons. Thus the atom has 8 protons. In order to find the neutrons, one must simply subtract the number of protons and one is left with the number of neutrons. 19 - 8 = 11. 11 neutrons.
