Answer:
a. The electrons provide energy for the H+ pump to transport more H+ ions into the thylakoid space.
d. The photolysis of water releases H+ ions into the thylakoid space.
Explanation:
This question describes the first stage of photosynthesis, which is LIGHT-DEPENDENT REACTION. The light dependent reactions involve creating ATP (energy carrier) and NADPH (electron carrier) needed for the Calvin cycle (light independent stage) to occur.
The ATP is formed by pumping hydrogen ions (H+) into the thylakoid space/lumen, hence, creating a electrochemical gradient needed for ATP synthase to synthesize ATP. The buildup of H+ ions is caused by:
- The electrons that arise when light photons hit a chlorophyll molecule is used to provide energy for the H+ pump to transport more H+ ions into the thylakoid space.
- The photolysis of water results in the production of electrons (e-) and hydrogen ions (H+). These hydrogen ions are released into the thylakoid space.
Answer:
divergent, convergent and parallel evolution
Explanation:
The evolution of analogous structures is called convergent evolution which occurs due to different organisms exploiting the same environment. Divergent evolution is basic structural forms of organs with the same embryonic origin are modified to serve different functions because of exploiting different ecological niche. Parallel evolution occurs when two species evolve independently of each other, maintaining the same level of similarity. Parallel evolution usually occurs between unrelated species that do not occupy the same or similar niches in a given habitat.

Atoms<span> vs. </span>Ions<span>. </span>Atoms<span> are neutral; they contain the same number of protons as electrons. By definition, an </span>ion<span> is an electrically charged particle produced by either removing electrons from a neutral </span>atom<span> to give a positive </span>ion<span> or adding electrons to a neutral </span>atom<span> to give a negative </span>ion<span>.</span>
Answer:
If two snails are hermaphrodites, which parents can become fertilized?
Explanation:
Answer: both parents can become fertilized because hermaphrodite snails have the sexual organs of both genders.
