<u>Answer:</u> "Chemical fossils"evidence supports the notion that sponges are some of the earliest known multicellular animals.
<u>Explanation:</u>
Sponges are multicellular animals, may belong to Ediacarian period likely to be 80 million years ago or earlier. They catered through a complex system of internal channels, by moving seawater.
Sponges are soft-bodied and very rarely protected as fossils, therefore finding evidence of existence is giant task. The key of their existence came to know from abnormal chemicals which is a steroids of a particular type generated sufficiently by them but virtually never by ordinary organisms.
Analysis of long strata sequence found in Oman and researchers have been able to extract these "chemical fossils" from samples spanning tens of millions of years — before, during and after the Ediacarian period.This gave clear evidence that sponges had to have evolved long before the great variety of multicellular organisms proliferated at the dawn of that time.

Answer:
Letter b. Gluconeogenesis
Explanation:
Immediately after eating we use the sugars in the food and utilize for energy and last a couple of hours. After that and about 15 hours later our body uses the energy stored in the liver in the form of glycogen, a process called glycogenolysis, that is the action of breaking the glycogen to free the energy. After 24 hours, the body starts to use another molecule for energy like fatty acids and start to synthesize glucose from other precursors, this process is called gluconeogenesis, and fuels the vital organs like the brain to maintain its function.
