Which statement describes a difference between the nitrogen and carbon cycles?
The nitrogen cycle occurs entirely in the ocean.
The nitrogen cycle requires a process called nitrogen fixation that is carried out by certain bacteria.
The carbon cycle requires freezing temperatures.
The carbon cycle involves only plants.
Answer:
The nitrogen cycle requires a process called nitrogen fixation that is carried out by certain bacteria
The primary distinction between the carbon and nitrogen cycles is that the former involves recycling carbon, whilst the latter involves recycling nitrogen. There are numerous ways for both systems to recycle carbon and nitrogen. With gases, both cycles begin and end. Thus, option B is correct.
What between the nitrogen and carbon cycles?Both go through chemical changes that change the shape of the molecules they are contained in. All organisms that are living contain both nitrogen and carbon. Both entail releasing the element into the atmosphere in a molecular form. The cycles start and end as gases.
Therefore, The amount of nitrogen that can be absorbed into organic matter and then recycled rises as the flux of carbon does.Both involve releasing the element as a molecule form into the atmosphere. As gases, the cycles begin and finish.

What is the least diverse species in PA
Hi. Your question is incomplete and it would be necessary for a text, a table, a graph or any other element that demonstrates the diversity of species to be presented for this question to be answered. However, I will try to help you as best I can.
The word "diversity" refers to differences and varieties that the same element presents. In this case, a species with little diversity is a species that shows little or no difference between its members. So, to answer your question, you need to identify the species that has the least difference within the community it makes up. For this, you will need to analyze your question complete, with all the elements that make it up.

Ferns have vascular tissue, an adaptation to life on land, but they have an ancestral reproductive trait that tends to limit them to moist habitats. What is it?
Answer:
The correct answer is - flagellated sperm.
Explanation:
In ancestral trait that is flagellated sperm in ferns that were limited to moist habitat has sperms that must swim to the eggs. This is why ferns often require splashing water for the movement of sperm to points near female gametangia during reproduction.
Fern now adapted the vascular system to get life on the life and they are not limited to the water bodies, however, flagellated sperm is the ancestral reproductive trait.

How does interphase prepare cells for mitosis?
Answer:
The largest part of the cell cycle is the interphase. Some 80-90% of the life of a cell is spent inter phasically. This is the time for a cell to grow and prepare for cell breakdown.
Explanation:
The cell prepares for cell division, also for interphase (which includes mitosis and cytokinesis). The cell grows larger until its starting point has doubled in size. The first stage, called the G1 phase, takes place.
The S phase is the next phase of the interface. The cell's DNA is copied this time. There are two DNA sets so that each daughter cell can receive one copy.
The final part of the intersection is the G2 phase. The cell is about to grow. All organelles like the endoplasmic reticulum and Golgi device will be doubled.
The interface is when the cell grows and produces sufficient matter to be divided into two cells. Before mitosis can start, the interphase must be completed.
