He nitrogen cycle is one of the most important (and complex!) of the biogeochemical cycles. Why is nitrogen important?

gayaneshka [121]

Nitrogen is an essential part of proteins and nucleic acids (DNA).

<h3>Why is nitrogen important?</h3>

All living things require nitrogen. It is a part of proteins, ATP, chlorophyll, DNA, and RNA. Given that it makes up a significant portion of the structures of biomolecules in living organisms, its synthesis and consumption in the biogeochemical cycle are of highest importance. Proteins are made up of amino acids (NH2 group).

The structural development of living species' genetic material (DNA, RNA) also involves nitrogen. It is a part of the nitrogenous bases, which together with other nucleotides create RNA and DNA.

Therefore, a nitrogen deficit can cause major structural issues for such an organism.

<h3>What happens if nitrogen cycle is disrupted?</h3>

A number of undesirable consequences can result from the nitrogen cycle being disrupted. For instance, an abundance of nitrogen in aquatic systems leads to eutrophication. Acid rain can be caused by a rise in atmospheric nitrogen.

The majority of ecosystems can tolerate low nitrogen levels since the majority of nitrogen is not biologically accessible in nature. Ecosystems become out of balance when humans significantly increase the quantity of nitrogen that is accessible through fertilizers, fertilizer use, and other means.

Claire is investigating potential and kinetic energy using a large ball. For her investigation, Claire will stand at the top of

uranmaximum [27]

The ball's potential energy will decrease, and its kinetic energy will increase.

Explanation:

The ball's potential energy will decrease down the slope and its kinetic energy will increase.

Kinetic energy is the energy due to the motion of a body.

K. E = $\frac{1}{2}$ m v²

m is the mass of the ball

v is the velocity of the ball.

Potential energy is the energy due to the motion of a body down slope.

It is expressed as:

P.E = mgh

m is the mass of ball

g is the acceleration due to gravity of the body

h is the height.

We can see as the body drops down the slope, the height diminishes and the velocity increases.

What is the mole to mole ratio of LiOH to HBr for the following reaction?

umka21 [38]

Explanation:

so moles = mass ÷ mr (1+ 79.9)

so 10.00g ÷ 80.9

which is 0.1236093943

so to 3 S.F is 0.124 moles

also there is 1 to 1 ratio for LiOH to HBr

hope this helps :)
