Giving sufficient folic acid during the first month of pregnancy can help five better health condition and prevent birt defects.

<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:
Fatty Acid
Explanation:
Lipids are fats, so the only sensible answer is Fatty Acid.
Answer: glucose molecules.
Explanation: cellular respiration is a process by which glucose molecules are broken down in the presence of oxygen into carbon dioxide and water with the concomitant release of energy in form of ATP. The equation for cellular respiration is C6H12O6 + 6O2 --> 6CO2 + 6H2O + Energy.
Cellular respiration is divided into four stages:
1). The breakdown of glucose into two molecules of pyruvate.
2). The conversion of pyruvate to Acetyl CoA.
3). The oxidation of acetyl CoA in the Krebs cycle to produce ATP, FADH2 and NADPH and;
4). The oxidation of FADH2 and NADPH in the electron transport chain to generate more ATP.
