I would say c would be the best.
A) both have strong scientific support.
The cell membrane helps to transport ions, nutrients, and waste.
Proteins are important biomolecules. Proteins are synthesized and often packaged for secretion into other cells within an organism. A variety of organelles play a role in producing, packaging, and moving proteins.
Organelles of Eukaryotic Cells
Organelle Function
Nucleus The “brains” of the cell, the nucleus directs cell activities and contains genetic material called chromosomes made of DNA.
Mitochondria Make energy out of food
Ribosomes Make protein
Golgi Apparatus Make, process and package proteins

<u>mechanism:</u> the process of evoluton .
Evolution is the process by which veriety of modern organisms have descended from ancient ancestors. Evolution is responsible for both the remarkable similarities of all 0rganisms and the amazing diversity of that organisms but exactly how does it work? Fundamental of the process of evolution is genetic variation upon which selective forces can act in order for evolution to occur.
Examines the mechanisms of evolution focusing on:
•<u>Decent </u>: the genetic differences that are heritable and passed on to the next generation successfully.
• <u>mechanisms of change</u>: Mutation, migration (gene flow), genetic drift, and natural selection are act as mechanism of change .
• The random nature of genetic drift and their effects .
• How variation, differential reproduction, and heredity result in evolution natural selection
.
• How different species can affect each other's evolution through co-evolution.
All of these mechanisms can cause changes in the frequencies of genes produce change in in populations, and so all of them are mechanisms of evolutionary change. However, natural selection and genetic drift (genetic flow) cannot operate unless there is genetic variation among organisms.
