Why do our bodies rearrange the food we eat and the oxygen we breathe (O2) into carbon dioxide (CO2) and water (H2O)?

Answer:

The Answer is

A: In order to release the energy found in food

Explanation:

Your body cells use the oxygen you breathe to get energy from the food you eat. This process is called cellular respiration. During cellular respiration the cell uses oxygen to break down sugar. Carbon dioxide is the waste product of cellular respiration that you breathe out each time you breathe.

garik1379 [7]

We use the classification system when grouping organisms, which are very diverse. The sub-group with the least amount of diversity is the species. The measure of diversity in this classification will of the variation in genome and physical characteristics. The species have a slight variation in the genome and phenotype compared to the amount of variation in a genus, where related species are clubbed together. The amount of diversity increases from the nodes of a classification tree to its root or parent (kingdom).

Products of glycolysis include:
Sveta_85 [38]

Answer: c. 2 pyruvate molecules

Explanation:

Glycolysis is the first step it the cell respiration cycle. It turns one molecule of glucose into two molecules of pyruvate by a series of reactions catalyzed by different enzymes.

It starts by using 2 ATP to turn glucose into fructose-1,6-bisphosphate, which then divides in two and releases 4 ATP when it turns into two pyruvate molecules.

Thus glycolysis consumes 2 ATP and releases 4 ATP (giving a net gain of 2 ATP) and 2 pyruvate molecules.

Excited about the fungus chemical's promise for treating cancer, you write up your experimental results and send the paper to a
jeka57 [31]

Answer:

All of them

Explanation:

The effect may not be real because we don't know if the results are reproducible: Peers can identify flaws in the experimental design because an experiment must have a clear design in order to be reproducible by other researchers or else they would not have scientific validity.

The treatment kills cancer cells, but it might simply be a poison that kills all cells—even normal cells: It is possible that in the design of the experiment carried out only cancer cells were used but it had not been performed in healthy cells, which would imply the possibility that the fungus kills all the cells.

Cell samples were taken from too few patients: This may be another mistake because when only a small sample is analyzed it is not certain if the fungi are the ones that kill the cancer cells or are other conditions of the analyzed patient.

Increasing the volume of air that reaches the alveoli and takes part in gas exchange will cause blood pH to:
Karolina [17]

Answer:

B. increase, because the partial pressure of CO2 in the blood will decrease.

Explanation:

The presence of carbon dioxide gas in blood imparts H+ ions due to its reaction with H2O and thereby, lowers down the blood pH.

When more air reaches alveoli, the rate of gaseous exchange is increased. More of the carbon dioxide is removed from the blood and is released out of the body via exhalation.

Removal of carbon dioxide from blood would increase the pH of the blood since the partial pressure of CO2 in the blood would decrease.
