Answer:
Through the photolysis of water molecules
Explanation:
<em>When the electrons in photosystem II gets excited, released and travel down to the electron transport chain, the electrons are replaced by the electron released by the cleavage/photolysis of water.</em>
<em>Water molecule is cleaved resulting in the formation of hydrogen ion, oxygen gas and electrons. The electrons then replace those lost by photosystem II.</em>
Answer:
The three anatomical structures that, in order, contribute to the production of mature sperm are the epididymis, seminal vesicle and prostate.
Explanation:
The sperm and the first seminal fluid are produced and found initially in the seminiferous tubules of each testicle. From there they move on to several structures that contribute to the maturation process:
- Each <u>seminiferous tubule </u>drives the sperm to the epididymis, through the vas deferens, where the sperm can be for a long time and complete their maturation process.
- From the epididymis, the sperm pass to the seminal vesicle, which produces more seminal fluid to give nutrients to the sperm and facilitate its movement.
- Finally, and before being expelled outside, the seminal fluid receives the prostatic secretion in the prostatic urethra, a viscous and whitish liquid that completes the seminal fluid content.
The process of maturation of sperm is of importance for the process of sexual reproduction.

<u> Allele frequencies to change from one generation to the next.-</u>
<u>B. </u><u>Mutation</u><u>; C. Random genetic drift; D. </u><u>Migration</u><u>; F. Natural selection</u>
- Selection, mutation, migration, and genetic drift are the mechanisms that effect changes in allele frequencies.
- When one or more of these forces are acting, the population violates Hardy-Weinberg assumptions, and evolution occurs.
Why do allele frequencies change from one generation to the next?
Random selection: Allele frequencies may fluctuate from one generation to the next when people with particular genotypes outlive those with different genotypes.
No mutation: Allele frequencies may fluctuate from one generation to the next if new alleles are produced via mutation or if alleles mutate at different rates.
What are 5 factors that cause changes in allele frequency?
- A population, a collection of interacting individuals of a single species, exhibits a change in allele frequency from one generation to the next due to five main processes.
- These include natural selection, gene flow, genetic drift, and mutation.
