Answer:
I think D) Glycolysis
Explanation:
<em>Glycolysis</em> is the <em><u>first pathway</u></em> used in the breakdown of glucose to extract energy. It takes place in the cytoplasm of both prokaryotic and eukaryotic cells. It was probably one of the earliest metabolic pathways to evolve since it is used by nearly all of the organisms on earth.
If there were an interruption in the carbon cycle, life on Earth as we know it would be in danger of being disrupted. ... Without carbon dioxide, the plants would not do as well, and potentially die, creating a problem for all the animals on the planet, Since they have to breathe oxygen to live.

Letters are the easiest way of modeling a Punnett square. The big letters mean it's dominant, while the lower case means it's recessive. Dominant traits will show up over the recessive traits. The answer is 75% because if the female is heterozygous, her alleles would be Ll, and as I said before, the big letters take over the little letters in any case.
I hope this helps :)
HABITAT- marine environments that range from the shallow estuarine to the deep sea
ADAPTATIONS
1. They are five- sided radial symmetry
2. They are able to regenerate body parts , and some species of sea stars are even able to grow a new body from a severed arm.
3. They have a water vascular system
