prokaryotic cells do not have a nucleus.
Answer:
Cell level organization
Explanation:
Organisms are composed of different level of organizations like atomic level, molecular level, cell level, tissue level, organ level, system level after which whole organism if formed.
If we talk about <u>Arachnoidiscus</u> <u>ehrenbergi </u> it is one celled organism belonging to a group of algae. If we talk about human stomach it is an organ made up of several tissues which in-turn are made up of several cells.
So what is common in both?
It is a cell that is common in both, because cell is the basic unit for life of <u>Arachnoidiscus</u> <u>ehrenbergi </u>and a unit of the composition of whole stomach.

The correct answer is iron, because it is often not included in children's multivitamin/mineral supplements. Iron is an important element for our health. It is especially important for the proper functioning of our red blood cells and it is found in many foods. Although iron is essential, too much can lead to iron toxicity. Iron poisoning was the leading cause of death from the medicine overdose in children younger than 6 years until the ends of the 1990s. But the trend has since changed due to better warning labels, education of prescribers, changes in iron preparations, and consumer awareness.
Answer:
B.
Explanation:
A is wrong because pyruvate would enter the Krebs cycle under aerobic condition (when oxygen is present). Hence the name aerobic cellular respiration
C. I do not really too much about fructose or the concentration of oxygen, but I can assure that this answer choice is not correct.
D is wrong because NADH would be converted from NADP+. Either with oxidation or reduction, and this helps to keep this process going.
B is correct because fermentation is another word for anaerobic cellular respiration. The process takes place with the absence of oxygen. It either goes through Alcoholic or lactic acid fermentation.
I hope this helps!
