The correct answer that would answer the given question above would be EXPERIMENTATION. The scientific method uses observation to gather information, and to answer the questions based on the information gathered, this would involve experimentation. This is the testing of the information so that it would given a clear evidence on the answer. Hope this answer helps.
Answer: B) energy released from exergonic reactions.
Explanation:
Cell metabolism is the set of reactions that occur in the cellular environment to synthesize or degrade biomolecules to produce energy. Synthesis metabolism of biomolecules is known as anabolic (anabolism) and catabolic degradation (catabolism).
Endergonic reaction (product has more energy than reagents) and requires energy to occur. Anabolism occurs when the cell has sufficient energy or substrate. Catabolism, in turn, occurs in situations in which the body needs energy, such as between meals and fasting.
The reactions of anabolism and catabolism are opposite but occur in an articulated manner, allowing the maximization of available energy. Thus, while catabolism occurs spontaneously, an exergonic reaction with ATP production, anabolism is non-spontaneous, or endergonic, requiring energy to occur. In other words energy that drives endergonic reactions is often obtained from B) energy released from exergonic reactions.
Both photosystems contain many pigments that help collect light energy, as well as a special pair of chlorophyll molecules in the heart (reaction center) of the photosystem. The special pair of photosystem I is called P700, while that of photosystem II is called P680.
Because electrons are “pulled” towards the oxygen.
Codominance.
Codominance occurs when, for example, a Dominant Blue color gene for a leaf crosses with a Dominant White color gene for a leaf. The genotype would be BW. This would result in, for example, a blue and white spotted leaf color. INCOMPLETE dominance occurs when both dominant alleles blend together, resulting in, eg, a pale blue color resulting from the blue and white colors mixing.
