Answer:
Both male and female gametes are created during the process of meiosis. The formation of male gametes or sperm is called spermatogenesis. After telophase II of spermatogenesis, there would be <u>four</u> male gametes created that are all genetically <u>haploid.</u>
Explanation:
Telophase II is the final step in Meiosis II. In Telophase II of the spermatogenesis chromosomes travels to opposite poles and are covered by a nuclear envelop. The two parent cells result four daughter cells which are haploid (1n).
Answer:
b. the 20 amino acids found in proteins differ in the composition of their R groups, which may be either polar or charged.
Explanation:
Since the proteins are polymers joined by a big number of amino acids, all the joins occur the same way because in all the amino acids there is always one part that is exactly the same in all of them.
The rest of the molecule in the amino acids, the R group, is different in each one, that is the characteristic of each one, and this is the part that can give the name and some other chemical properties.
Answer:
They are a major absorber of carbon dioxide.
Explanation:
Plants present deep under the seas and algae over the Oceans and under it absorb huge amount of CO2 from our atmosphere.

Answer:
A
Explanation:
The light energy from sunlight in photosynthesis is used to split the water molecule into H+ and O2-. The H+ is then used to reduce NADP+ to NADPH. Through photophosphorylation, the energy from the sun is also used to make ATP from ADP. As the electrons are passed from one protein to the other in the chain, the energy released is what is used to create ATP.
Oxygen is evolved out as a byproduct
NADP+ + 2e- + 2H+ --> NADPH + H+
