Explain how thing that plants or animals do are done by the work of cells.
ipn [44]
<span>Basically because of the presence of cellular organization and hierarchy which organs are influenced by individual autonomic cells.

The cellular organization relates with one another since the colossal cell, the organ system is fundamentally composed of cells. Cells are the building blocks of these structures and which creates such organ and organ system. They associate as one cell intercommunicates with another cell until all received the message and translates it and sends it with another organ and to cell -vice-versa. And also, they become interdependent with the other cell -other tissue -other organs -other organ system. </span>
Cells when grouped form tissues, when group of tissues are formed together they make organs, some organisms skip from organs to organs systems to form an existing organism as a whole. Describing how is the cells group is the process of multiplication of cell or the so-called cell division, mitosis.This mechanism of each cell produces another cell that binds together and produces again, repeatedly, to be a larger system called now the tissue as explained earlier. How? Through cell division called, mitosis. Excerptmeiosis –cell division specifically in the sex cells.<span> </span>

Describe how the complete oxidation of 1 mole of glucose can generate 32 ATPs. You should include i) products of anaerobic glyco
inn [45]

Answer:

Explanation:

1.During glycolysis,four molecules of ATP are formed,and two are expended to cause the initial phosphorylation of glucose to get the process going.This gives a net gain of two molecules of ATP

For every glucose molecule that undergoes cellular respiration, the citric acid cycle is carried out twice; this is because glycolysis (the first stage of aerobic respiration) produces two pyruvate molecules per glucose molecule. During pyruvate oxidation (the second stage of aerobic respiration), each pyruvate molecule is converted into one molecule of acetyl-CoA—the input into the citric acid cycle. Therefore, for every glucose molecule, two acetyl-CoA molecules are produced. Each of the two acetyl-CoA molecules goes once through the citric acid cycle.

The citric acid cycle begins with the fusion of acetyl-CoA and oxaloacetate to form citric acid. For each acetyl-CoA molecule, the products of the citric acid cycle are two carbon dioxide molecules, three NADH molecules, one FADH2 molecule, and one GTP/ATP molecule. Therefore, for every glucose molecule (which generates two acetyl-CoA molecules), the citric acid cycle yields four carbon dioxide molecules, six NADH molecules, two FADH2 molecules, and two GTP/ATP molecules. The citric acid cycle also regenerates oxaloacetate, the molecule that starts the cycle.

While the ATP yield of the citric acid cycle is modest, the generation of coenzymes NADH and FADH2 is critical for ATP production in the final stage of cellular respiration, oxidative phosphorylation. These coenzymes act as electron carriers and donate their electrons to the electron transport chain, ultimately driving the production of most of the ATP produced by cellular respiration.

How would you explain the “density of the elephant population” to someone?
cricket20 [7]

Answer:

The most effective experimental approach to assess the effects of elephant impact on vegetation is to assess plant responses under differences in elephant density. It is important that other factors, such as soils or habitat structure are held constant so that the only factor which varies is elephant density.

Which of these microbes causes "walking pneumonia"?
Karolina [17]

Answer:

Walking pneumonia can be caused by the microbes <u>mycoplasma pneumoniae</u>  and <u>chlamydophila pneumoniae.</u>

Explanation:

Atypical pneumonia, commonly known as walking pneumonia, is a type of pneumonia which is not caused by a single pathogen or a single type of pathogen. The organisms that cause walking pneumonia are called atypical organisms. Therefore, disease can be caused by special bacteria, fungi, viruses and protozoa.

Examples of atypical organisms include: <u>chlamydophila pneumoniae</u>, chlamydophila psittaci, francisella tularensis, <u>mycoplasma pneumoniae</u>, etc.

<u>Therefore, Walking pneumonia can be caused by the microbes </u><u>mycoplasma pneumoniae</u><u>  and </u><u>chlamydophila pneumoniae</u><u>.</u>
