How are the carbon, nitrogen and oxygen cycles similar

Biology
1 answer:
Sever21 [200]3 years ago
6 0

Answer:

Firstly, they are all biogeochemical cycles. They cycle substances through the different systems. So this means that these substances like elements, compounds, and the like go through the hydrosphere, atmosphere, geosphere, and biosphere. It involves both the living and non-living things on Earth, all playing a role in transforming substances into something that can be used, only to be recycled again to provide for the other in a cyclic manner.

For example the oxygen cycle involves how oxygen is produced and used over and over. As we exhale Carbon Dioxide, it gets absorbed by plants which use it, along with water and light, to produce their own food in a process called photosynthesis. A by-product of this process is oxygen which we take in and use and we exhale Carbon dioxide again.

What subatomic particle is transferred to the electron transport system from the krebs cycle?
mario62 [17]
<span>Electrons are transferred via Hydrogen atoms bound to NAD (nicotinamide adenine dinucleotide). Essentially, the krebs cycle harvests electrons (Hydrogen atoms) from pyruvates in the inter-membrane space via NADH and these feed into the electron transport chain to power ATP synthase to generate ATP.</span>

If a male parent has two dominant alleles for a
taurus [48]

Answer:

The offsprings will express the dominant trait of the male parent.

To understand this, lets make a punnet square. Let's consider the dominant alleles of the male parent to be DD and the recessive alleles of the female parent to be dd.

     d         d

D   Dd     Dd

D    Dd    Dd

The results from the punnet square depict that all the offsprings will have a heterozygous genotype but ad the dominant allele masks the effect of the recessive allele hence, the offsprings will show the phenotype of the dominant allele.

Which term means stricture or narrowing of the rectum?
Vika [28.1K]
A general term for narrowing would be contracting. I assume that this is applicable to the rectum, as it is a muscular tissue, and muscles are able to expand (extend, rather), and contract.

Hope this helps. And I hope I'm the brainliest!

What is the weakest part of a developing, adolescent long bone?
shutvik [7]

Answer:

The weakest part of a long developing and adolescent bone is called growth cartilage (epiphyseal plate)

Explanation:

Both children's bones and adults' bones are at risk of injury. However, in the case of bones in a child, they are subject to an injury known as a growth cartilage fracture or epiphyseal plate. These growth cartilages are areas that are in full development in the vicinity of long bones. Its function is to help establish the length and shape of the bone in the process of maturation. The growth of a long bone happens from the end next to the growth cartilage. In adulthood, these growth cartilages are strengthened forming the bone.
