(G1) - The stage where the cell spends most of it's life. Doing it's job (job being what the cell was created for, such as being a muscle or bone cell.) and being alive.
(S) - S phase is where cell performs synthesis (Hence the name of the stage, S.) and duplicates it's nutrients and everything inside it, most importantly though you must know that this is the stage where DNA is copied.
(G2) - This is the stage where the cell is preparing to entire mitosis, it's also known as the pre-mitotic phase. This phase takes place immediately after DNA has been replicated in the S phase. After the G2 phase is finished, mitosis begins.
Answer:
When your body does become too cold, its automatic response is to tighten and relax the muscles in rapid succession to warm up. This is also known as shivering.
Amino acids are similar to carbohydrates and lipids as they all contain carbon, oxygen, and hydrogen.
Amino acids are the organic compounds involved in the synthesis of proteins. The basic structure of amino acids is composed of an amino group, a carboxylic group, a hydrogen atom and a variable R group all bonded with a common α-carbon atom.
Lipids are the organic molecules that consists of fats and oils. The general structure of lipid is composed of a glycerol backbone, with 2 long fatty acid chains attached to each hydroxyl group and a terminal hydroxyl group attached to phosphate group.

It relates perfectly because the experts of respiratory therapy are usually dealing with patients that can’t breathe or are having <span>blockage in their lungs. The exmaple could be in an emergency room where a person cannot breathe and the therapists checks the volume of oxygen in the patient and his lungs to see if there is something blocking the airways</span>
Answer/Explanation:
EGFR stands for epidermal growth factor receptor. It is a transmembrane protein acting as a tyrosine kinase receptor for epidermal growth factor ligands, which are associated with promoting cell division and proliferation. When epidermal growth factor binds to the receptor, it becomes activated and undergoes dimerization and autophosphorylation.
A mutation could occur making the receptor overactive. That is, it does not require ligand binding to become activated, meaning it is always in an "on" state. This would lead to uncontrolled proliferation, a hallmark of cancer.
