Answer:

Option B. "It may change due to new scientific evidences. "  is correct about big bang theory

<u>Explanation</u>:

Various evidences has been found from time to time, even scientists are working over it now, and certain evidences are yet to be found which can further alter the evidences now we are having. The theory is the cosmological model. When our universe was born it was unimaginably hot.

This theory also gives information about the expansion of the earth with high density and also having very high temperature. After the first expansion the earth cooled down subsequently which permitted the formation of the subatomic particles. And later the atoms. big clouds of the elements merged afterwards due to the gravity. Most part of the universe is dark part, which is still a mystery.

which represents the optimal condition for most enzymes in the small intestine? 1. pH12 2.45°C 3. pH10 4.pH2 5.37 °C
mojhsa [17]

Answer:

5.37 °C

Explanation:

The optimal condition for most enzymes in the small intestine is 37 °C.

Enzymes are responsible for mediating several biological processes in the human body. The optimal condition for enzymes in the small intestine has an optimum pH of about 7.5 and the temperature is 37 °C, which is the normal body temperature of the human body.

Hence, the correct option is "5. 37 °C".

Does lemon juice have more or less H+ ions than it has OH- ions? explain
LekaFEV [45]

Acids are substances that provide hydrogen ions (H+) and lower pH, whereas bases provide hydroxide ions (OH–) and raise pH. The stronger the acid, the more readily it donates H+. For example, hydrochloric acid and lemon juice are very acidic and readily give up H+ when added to water. ( source : https://courses.lumenlearning.com/wmopen-nmbiology1/chapter/the-ph-scale/ )

Why is the 3-dimensional shape of a macromolecule (ex: protein) important to know from the perspective of understanding
sineoko [7]

Answer:

A, B and C may be true

Explanation:

The three-dimensional structure (3D) of a protein, also known as tertiary structure, is critical to its function. In general, the 3D protein structure consists of alpha-helix and beta-sheets (secondary structures) associated through disordered coiled-coil regions. Genetic mutations may cause modifications in the 3D protein structure by modifying amino acids that are added to the growing polypeptide chain during the process of translation. In consequence, the relationships among amino acids (i.e., the intermolecular attractive forces that hold them together) may also be altered by these mutations. In general, mutations that generate amino acid changes at the active site of the enzyme will have a deleterious effect, thereby decreasing or inactivating protein function. However, there are situations where a mutation may be beneficial and can eventually increase the rate of reaction of a protein.
