Like all plants, they photosynthesize – that is, they use sunlight and carbon dioxide to make food. A byproduct of photosynthesis is oxygen. Scientists believe that phytoplankton contribute between 50 to 85 percent of the oxygen in Earth's atmosphere.

The cell continually produces carbon dioxide as a by-product of cellular respiration. How does the cell keep the carbon dioxide
ser-zykov [4K]

Answer:

Breathing out the carbon dioxide

Explanation:

Blood is the medium through which carbon dioxide is transported to the lungs from where it is exhaled out.

The Carbon dioxide produced in cells after respiration diffuses into the blood  in exchange of oxygen delivered to the cells for further respiration. Blood while flowing through the lungs passes carbon dioxide to its alveoli which is then exhaled out and oxygen is inhaled from outside.

Hence, cell keep the carbon dioxide from building up in the cytoplasm and poisoning the cell by exhaling CO2.

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.

Define population. How is a population different from a community
icang [17]
A population is all the organisms of the same species in a group, like humans. Population is different from a community in that a population is every organism of the species grouped as a whole, and a community is a certain number of organisms within the whole population. That may not make sense, but that’s as good as I can describe it.
