Answer:
The left atrium pumps blood into the lungs!
Explanation:
Answer:
A cell that has Damaged p53 gene , A) may become Cancerous; B) may experience uninhibited and out of control cell division; C) may accumulate multiple mutation.
Explanation:
- p53 gene is a tumor suppressor gene that encodes a polypeptide that acts as a transcription factor.
- Mutation in p53 is associated with 50% of human cancers.
- Loss of p53 removes DNA damage check point.
- Mutation in p53 prevents DNA repair and the apoptosis of cells that contain irreparable damage.
- as a result the cells may accumulate multiple mutations.
- Since Functional p53 promotes DNA repair and arrest the cell cycle if a damaged DNA is present; any mutation in p53 may result in uncontrolled cell growth and tumor formation.
Answer:
Answer is Option C.
The concentration of organic molecules by the process of dehydration synthesis can facilitate their assembly into macro molecules.
Explanation:
Macromolecules are large molecules formed by covalent bonds between monomers. They are a growing chain of monomers assemble through a process called dehydration synthesis in which one monomer forms a covalent bond with another monomer by releasing a water molecule. This is a process that requires energy. For example, two glucose molecules (monomers) combine to form a single maltose molecule. As a new covalent bond forms between the two glucose molecules, a water molecule is released.
Evaporation is a process in which water vapor is formed from water. The tendency of dissimilar particles to stick together is known as adhesion.
