Answer: Yes.
Explanation:
Fermentation is a general term denoting anaerobic degradation of glucose or other organic nutrients in various products to obtain energy in the form of ATP. Fermentation occurs when, after glycolysis, the Krebs cycle is not performed, because the organism does not have it or because this pathway is blocked, such as during hypoxia (lack of oxygen). Fermentation is a process used by bacteria to obtain energy, does not use oxygen and occurs in the cytoplasm of cells, ie an intracellular process, and each step is catalyzed with the help of different enzymes.
Some industries use this process in the production of some products, known to all of us, such as:
1. yogurt is produced by the famous lactic fermentation, where bacteria called lactobacilli to produce lactic acid.
2. bread and beer are produced by alcoholic fermentation, where the fermentation is carried out by fungi (facultative anaerobic), which ultimately produce alcohol;
3. vinegar to that produced by acetic fermentation, which consists of a chemical reaction, where partial oxidation of ethyl alcohol occurs, obtaining acetic acid.
<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:
B and C
Explanation:
With the geocentric model they didnt have the technology to disprove the theory, and everyone wanted to believe that everything revolves around us.
and it accurately predicted that the planets moved in a circular motion they just didnt get the right order.
Photosynthesis makes the glucose that is used in cellular respiration to make ATP. The glucose is then turned back into carbon dioxide, which is used in photosynthesis. While water is broken down to form oxygen during photosynthesis, in cellular respirationoxygen is combined with hydrogen to form water.
