Select all that apply. Which statements correspond to cellular respiration? CO2 diffuses passively into the cell. CO2 diffuses passively out of the cell. CO2 must be pumped out of the cell. O2 diffuses passively when produced inside the cell. O2 diffuses passively when converted to CO2. O2 is pumped in and forces CO2 out.

Answers

The correct answer is:

CO2 diffuses passively out of the cell. O2 in respiration is converted to water. O2 diffuses in to the cell.

Explanation:

Cellular respiration is the chemical reaction in which glucose and oxygen are converted into water, carbon dioxide, and energy (ATP). In this reaction, glucose and oxygen are reactants, while water, carbon dioxide, and energy (ATP) are products. Cellular respiration is a set of metabolic reactions and processes that take place in the cells of organisms to change biochemical energy from nutrients into adenosine triphosphate and then discharge waste products.

CO₂ diffuses passively out of the cell. O₂ in respiration is converted to water. O₂ diffuses in to the cell.

Thus, The chemical reaction that turns glucose and oxygen into water, carbon dioxide, and energy (ATP) is known as cellular respiration.

Glucose and oxygen are the reactants in this process, and the products are water, carbon dioxide, and energy (ATP).

To convert biochemical energy from nutrients into adenosine triphosphate and eventually release waste products, cells of organisms undergo cellular respiration, a series of metabolic reactions and activities.

Thus, CO₂ diffuses passively out of the cell. O₂ in respiration is converted to water. O₂ diffuses in to the cell.

A taiga biome is DIFFERENT from a tundra biome because it has A) many coniferous trees.
B) cold winters and cool summers.
C) located in the northern hemisphere.
D) a layer of frozen soil called permafrost.

Answers

Answer:

The correct answer would be A) many coniferous trees.

Taiga and tundra represent the two coldest biomes of the land on the planet.

The average annual temperature of taiga lies between 41° Fahrenheit and 23° Fahrenheit whereas the temperature of the tundra lies below 23° Fahrenheit throughout the year.

It makes the major difference between the plant life of the two biomes. The taiga is characterized by the presence of coniferous forests which consist of spruces, pines, and larches.

In contrast, vegetation in the tundra is mainly composed of grasses, shrubs, mosses, sedges, and lichens.

the answer is A. The tundra is a frozen waste, having very little to no vegetation. While the taiga has conifers growing there
