NADPH is a reduced form of NADP+. The latter features an extra hydrogen ion in its chemical structure. When NADP+ transforms into NADPH, the other hydrogen ion is released as part of the reaction while the other hydrogen ion becomes a part of the NADPH structure.
Answer:
A trait that is neutral in one environment may be advantageous in another.
Explanation:
Neutral variation refers to the variation (either genetic or phenotypic variation) which is unaffected by natural selection. Neutral variation is known to increase genetic variation, which is a prerequisite to evolutionary change. An allele may be neutral in one environment and beneficial (or deleterious) in another. In consequence, neutral variation in one environment may increase the response to selection in different environmental conditions.
The correct answer is diffusion.
Aquatic respiration refers to the procedure whereby an aquatic animal attains oxygen from water. Fish and other aquatic species utilize gills to consume oxygen dissolved in the water and diffuse carbon dioxide out of the bloodstream.
Diffusion is a procedure in which a substance moves from a region of high concentration to the region of low concentration until equilibrium is attained. In the case of aquatic species, blood with a low concentration of oxygen molecules moves through the gills. The concentration of the oxygen molecules in water is greater in comparison to the concentration of oxygen molecules in the gills.
As a consequence, the molecules of oxygen diffuse from water (higher concentration) to a region of lower concentration, that is blood. In the same manner, the molecules of carbon dioxide diffuse from the blood, that is, high concentration to water, that is, low concentration.

Answer:
1. The gametophyte generation is haploid.
2. The embryo is diploid.
3. The megaspore is haploid.
4. The sporophyte generation is diploid.
Explanation:
1. Gametophyte- The gametophytic generation is the structure which produces gametes in the plant. Since the gametes are haploid, therefore, the gametophyte us considered the haploid.
2. Embryo- The embryo is formed after the fusion of fertilization when zygote develops, therefore, is considered diploid.
3. Megaspore- the big size spore which is formed from by the meiotic division of the megasporocyte, therefore, is considered haploid.
4. Sporophyte- the sporophyte generation develops from the embryo which is diploid therefore is considered diploid.
