Pituitary gland.
When you feel stress, the pituitary gland, at the base of the brain, increases its production of the hormone ACTH. This hormone tells the adrenal glands, found at the top of your kidneys, to increase their production of hormones. These stress hormones help you to concentrate, speed your reaction time, and boost your strength. Your hypothalamus also helps your body respond to stress.
Cells will usually divide if they receive the proper signal at a checkpoint in the G1 phase of the cell cycle. In mammalian cells , this checkpoint is called the restriction point. The G1 phase is a phase of the cell cycle that takes place in eukaryotic cell division. In this phase the cell synthesizes mRNA and proteins in preparation for the subsequent steps leading to mitosis. It ends when the cell moves into the S phase of interphase.
The name you're looking for is Gregor Mendel. He first saw it in his experiments with peas that had different traits (leaves, stem, colour, texture) etc.
Hope it helps!
Answer: Cell A does more work than cell B.
Mitochondria is the energy producer organelle of the cell. It produces energy in the form of ATP molecules. It is a membrane bound organelle which is only present in eukaryotic cells not found in prokaryotic cells. Presence of more number of mitochondria in the cell indicates that the energy requirement of the cell is more. This energy is required for cellular metabolism. Therefore, cell with more mitochondria works more than the one with less mitochondria.
