What is it important that carbon is recycled?

Biology
1 answer:
marshall27 [118]3 years ago
6 0
It's not so important that it be recycled ... after all, there's almost a limitless supply,
and there's no danger of ever running out of it.

What's important is to keep carbon out of the atmosphere.  In order to do that, we
need to reduce the amount of it that's released during so many of the processes
that we've been doing on a huge scale for the past 200 years, and invent ways
to capture the carbon that we DO continue to release, before it gets into the
atmosphere.

Explain the process to take place in stroma
Zepler [3.9K]
The Calvin cycle takes place in the stroma of chloroplasts. The Calvin cycle is the biological pathway of converting carbon dioxide into new molecules required for cellular growth. The Calvin cycle has three phases: carbon fixation, reduction and regeneration.

1. Which amino acids changed between the three species? List four of them below, using the number of the amino acid.
kirza4 [7]

The amino acids that changed between the three species are;

  • Amino acid 151 transited from valine to isoleucine in a warm adapted species.
  • Amino acid 201 translated from glycine to alanine in warm adapted species.
  • Amino acid 201 morphed from glutamine to lysine in warm adapted species.
  • Amino acid 201 translated from glutamic acid to aspartic acid in cold adapted species.

<h3>What were the changes in the chemical properties of the R-groups?</h3>

The changes in the chemical properties of the R-groups are given as:

  1. Both valine and isoleucine are nonpolar.
  2. Both glycine and alanine are nonpolar.
  3. Glutamine is an uncharged polar group and Lysine is a charged polar group.
  4. Both glutamic acid and aspartic acid are charged polar group.

<h3>How might the changes that you identified affect the protein’s structure?</h3>

In scenario 1 and 2, the modifications would have zero effect.

In scenario 3, the polar groups are detected on the surface of the protein, thus, it is correct to state that both glutamine and lysine are polar and the modifications will have zero effect.

With regards to scenario 4, the change will have  no impact, given that both glutamic acid and aspartic acids are R groups that are negatively charged.

<h3>Assuming that the mutations are adaptive, how should the changes that you identified affect the stability of the protein at low and high temperatures?</h3>

These mutations are critical for protein's three-dimensional structure stability.

For example, due to the proteins from thermophilic creatures, they are able to live at high temperatures and survive at low temperatures.

This is because they frequently have a large network of salt bridges on their protein surface, which offers thermo-stability to these proteins and prevents denaturation owing to the high temperatures in the environment.

The human male reproductive system
Tanya [424]

Answer:

              B) I and II

Explanation:

                     Male reproductive system produce gametes in the testis which is the part of male reproductive system. Testis are two in number normally which compose of seminiferous tubules which have spermatogenic cell which are responsible for the production of spermatids with the help of sertoli cells present in the seminiferous tubules.After production  of gametes the spermatid are delivered to the female reproductive system by copulating organ which in human is penis.the sperm 1st produces in the semeniferus tubules then transfer in to the rate testies ,epidydemis then vas deference and then urethra and then outside the body.
