Answer:
Membrane proteins perform a variety of functions vital to the survival of organisms: Membrane receptor proteins relay signals between the cell's internal and external environments. Transport proteins move molecules and ions across the membrane.
Explanation:
they help transport some substances through the membrane.

Primary producer, because it has to make it's own food.
Answer:
There are three types of RNA involved in protein synthesis:
messenger RNA (mRNA)
transfer RNA (tRNA)
ribisomal RNA (rRNA).
Explanation:
All three of these nucleic acids work together to produce a protein. The mRNA takes the genetic instructions from the nucleus to the cytoplasm, where the ribosomes are located.
Natural selection is one of the basic mechanisms of evolution during which those variations in the genotype that increase organism's chances of survival and procreation are preserved and multiplied from generation to generation at the expense of those that are less advantageous. In this case the following are postulates of natural selection; Individuals with certain traits are more likely to survive and reproduce, individuals in a population vary more likely to survive and reproduce, survival and reproductive success are variable among individuals in a population and lastly some traits differences are heritable.
