B.
The circulatory system would fail, and the entire organism would suffer.
C.
The organism would slow down its breathing, so that the heart could recover.
D.
Tissue from another part of the body would take over to keep the heart beating.

Which of the following is not necessary for a plant to do photosynthesis?A. Carbon dioxide
B. Soil
C. Water
D. Light

Answers

soil because that has to deal with roots, and photosynthesis happens in leaves. So the soil doesn't have anything to do with photosynthesis.

Soil! Although many plants live in soil, it is not exactly necassary for photosynthesis. Plants can actually grow in water instead of soil most times!

Hope this helps! : )

In a certain plant species, the allele for yellow seeds (Y) is dominant to the allele for green seeds. What is the phenotype result of a cross between a true-breeding yellow-seeded group of plants and a true-breeding green-seeded group of plants? A. all yellow seeds; no green seeds B. all green seeds; no yellow seeds C. 1/4 green seeds; 3/4 yellow seeds D. 1/4 yellow seeds; 3/4 green seeds @PinkFloyd

Answers

the answer is a because if u do a punnett square to get your results like i did, each plant would end up with the phenotype Y(yellow)y(green), and since they all have 1 dominant and 1 recessive, the dominant trait takes over, but the recessive trait is still there but it doesnt show up.

hopefully my answer helps u

Explain how trees help maintain air quality.

Answers

Trees help maintain air quality through many processes, by photosynthesis trees exchange gases from the environment and provide a good quality of air.

How do trees provide good quality air?

During photosynthesis, trees exchange oxygen and carbon dioxide, and the organism takes oxygen and releases carbon dioxide, this is the necessity of the organism to do cellular respiration and produce energy.

Trees also reduce the effect of the greenhouse effect, by removing all the carbon dioxide from the atmosphere, when they perform photosynthesis take all the carbon dioxide to synthesize food. They also remove particulate matter from the air to improve air quality.

Therefore, trees help maintain air quality, through photosynthesis and reduce the greenhouse effect.

Final answer:

Trees help maintain air quality by absorbing carbon dioxide, releasing oxygen, and filtering pollutants. They also reduce air pollution through shading, which reduces the need for air conditioning and lowers energy consumption.

Explanation:

Trees play a crucial role in maintaining air quality through a process called photosynthesis. During photosynthesis, trees absorb carbon dioxide from the air and release oxygen, helping to increase oxygen levels and reduce carbon dioxide levels. Additionally, trees trap and filter pollutants such as dust and smoke, improving air quality.

For example, in urban areas, trees can absorb harmful pollutants like nitrogen dioxide, carbon monoxide, and sulfur dioxide. The leaves of trees act like a filter, trapping these pollutants and preventing them from entering the atmosphere.

Furthermore, trees also help in reducing air pollution by providing shade. When trees provide shade, they help to cool the surrounding area, which reduces the need for air conditioning. As a result, there is less energy consumption and fewer greenhouse gas emissions associated with cooling buildings.

Mass extinction would most likely result from which of the following events?
A. A disease kills off a single species of predator within an ecosystem.
B. A wildfire burns a national park.
C. Global temperatures drop several degrees after several massive volcanic eruptions.
D. A massive earthquake strikes North America.

Answers

1. C. a species evolves at a slow, steady pace.

Gradualism, is the process by which a certain specie or creature undergo changes and variations in a limited and solely focusedly confined in long period of time.

2. A. A disease kills off a single species of predator within an ecosystem.

Mass extinction is a massive and global elimination in a certain specie or species. It doesn’t involve itself only in a secured and measurable area but it impacts the whole large-scale of population as a whole.
