How are the carbon and oxygen cycles interconnected?

A. The carbon dioxide produced during photosynthesis is used during respiration to produce oxygen.

B. The carbon on the surface of the Earth combines with oxygen in the air to form the water in the ocean.

C. The oxygen produced during photosynthesis is used during respiration to produce carbon dioxide.


D. The oxygen produced during photosynthesis becomes a component of water in the atmosphere.

Answers

Answer:

A.

Explanation:

Because carbon dioxide produce energy and releases oxygen

The oxygen and carbon cycles are interconnected as both produced or recycled by the living organisms as option C. The oxygen produced during photosynthesis is used during respiration to produce carbon dioxide.

Oxygen and carbon are moves between the atmosphere, biosphere, and lithosphere but the most important part is movement between the biosphere and atmosphere:

In the biosphere, carbon dioxide is used as a reactant to produce oxygen that moves to the atmosphere by the process called photosynthesis in plants.During cellular respiration atmospheric oxygen is used by the living organism to produce energy and releases carbon dioxide as a byproduct.

On the basis of the given explanation, the correct answer would be - Option C.

Sea otters regulate the presence of the sea urchins and thus, kelp is regulated for all organisms in the ecosystem. They help to keep enough kelp for other wildlife to feed on. Also, due to their ability to absorb carbon dioxide, the kelp aid in mitigating climatic change and also reduce erosion by reducing the speed of water at the coast.However, if there were too many sea urchins and no sea otter to regulate their production, the kelp would reduce and thus with no food in the ecosystem, it would collapse. As a result, the sea otter protects the kelp forests by checking the local sea urchin population. The sea otter is an example of a

Answers

Answer:

keystone species

Explanation:

The sea otter is an example of a keystone species in the scenario.

A keystone species is an organism that has a significant influence on the functioning of the entire ecosystem. Without this species, the ecosystem would either cease to exist in total or entirely different in structure. In other words, a keystone species is a fastener that holds the ecosystem together.

In this case, the sea otter indirectly regulates kelp for all organisms in the ecosystem by directly regulating the presence of sea urchins. Without kelps, several ecosystem functions such as climate change mitigation and erosion reduction would cease. Thus, the sea otter is playing a significant role as a keystone species.

How may mRNA be modified before it leaves the nucleus?

Answers

Answer:

The pre-mRNA molecules undergo three main modifications. These modifications are 5' capping 3' polyadenylation and RNA splicing which occur in the nucleus before RNA is translated.

Explanation:

mRNA compares to the hereditary succession of quality, and is perused by a ribosome during the time spent combining a protein.

How mRNA can be modified?

it should go through extra handling before it leaves the core. This might incorporate joining, altering, and polyadenylation. These cycles adjust the mRNA in different ways. Such alterations permit a solitary quality to be utilized to make more than one protein. Exons are segments of mRNA which become "communicated" or converted into a protein. They are the coding bits of a mRNA atom.

An archer shot a 0.06 kg arrow at a target the arrow accelerated at 5,000 m/s squared to reach a speed of 50.0 m/s as it is left the bow.During this acceleration what was the net force to the nearest newton?

Answers

Answer:

the net force to the nearest newton is 300 N

Explanation:

The computation of the net force to the nearest newton is shown below:

According to the newton second law of motion, the force is proportional directly to the change rate in momentum

So,

Resulted force = mass × acceleration

F = 0.06 kg × 5,000 m/s

= 300 N

Hence, the net force to the nearest newton is 300 N

Chloroplasts and Mitochondria are two organelles that are largely
responsible for the cycling of carbon through the ecosystems. What are
their functions?

Answers

Function for Mitochondria - Mitochondria are membrane-bound cell organelles (mitochondrion, singular) that generate most of the chemical energy needed to power the cell's biochemical reactions. Chemical energy produced by the mitochondria is stored in a small molecule called adenosine triphosphate (ATP).

Function for Chloroplast - In particular, organelles called chloroplasts allow plants to capture the energy of the Sun in energy-rich molecules; cell walls allow plants to have rigid structures as varied as wood trunks and supple leaves; and vacuoles allow plant cells to change size.
