Answer:
Phospholipid bilayer determinates which molecules can enter or exit the cell so its purpose is to be a checker in the middle. Cell membrane determinates the structure of the cell and it is the connection to the rest that happens in a cell.
Explanation:
Molecules can move in 2 ways: passive and active.
The only difference is the energy that is needed to do the movement.
In passive mechanisms, energy is not used, while in active transport, energy is needed. Diffusion or passive transport are moving the concentration from hight to low so the energy is not necessary. Active transport moves from low to a high concentration and it uses metabolic energy.
Messenger RNA (mRNA) molecules carry the coding sequences for protein synthesis and are called transcripts; ribosomal RNA (rRNA) molecules form the core of a cell's ribosomes (the structures in which protein synthesis takes place); and transfer RNA (tRNA) molecules carry amino acids to the ribosomes during protein
Answer:
Active site and protein.
Explanation:
The two components which are often found as part of an enzyme are Active site and protein. Proteins are referred to as macromolecules or macromolecules which consists of more or one of a chain of amino acid residue. They do perform an array of functions which are within organisms.
The answer is B- Embryological Development.
