The second to last answer
Gravity
Gravity is a force associated with all matter, pulling matter together. The force (which is a property of mass) is directly proportional to mass.
Explanation:
As the star fuses helium atoms in its center, enormous energy is generated and the atoms have a very high kinetic energy and want to escape from the center hence create great outwards pressure. However, the great mass of the center of the star creates enormous gravitation pull towards the center of the star. This gravitational force keeps the high kinetic atoms from escaping. The atoms keep fusing until the fuel is exhausted and the star ‘dies’.

Answer: The Statement that best describes the role of phosphorus in the body is that:
a. used to build proteins
Explanation: Phosphorus in the body helps to build up proteins for growth, maintenance, and repair of cells and tissues.
Answer: the expression of certain genes is affected by temperature
Explanation:
For organisms to survive changing environmental conditions, a lot of molecular processes occur in the genes.
For the arctic fox, enzymes coded by specific genes are periodically "switched on or off" depending on the temperature.
Thus, the change in colour can be EXPLAINED by the expression of certain genes affected by temperature
The results in unfavorable electrostatic repulsions between the carboxylate anions ,which reduces the likelihood that a proton would dissociate .
electrostatic repulsion refers to two particles of same charge that drive away each other.
carboxylate is the conjugate base of a carboxylic acid . It is an ion with negative charge .these are the anions formed by the deprotonation of the carboxy group in a carboxylic acid .
Dissociation means the breaking up of a compound into smaller constituents that are usually capable of recombining under other conditions .
