Explanation:
Cysteine contributes to the three-dimensional structure of a protein by forming covalent bonds with an identical amino acid in another part of the protein.
<h3>
What is the Cysteine Structure?</h3>
- Covalent disulfide bonds form between the sulfhydryl (-SH) groups of cysteines in different parts of a protein are very important in determining the three-dimensional shape of the protein.
- is a HOOC-CH-(NH2)-CH2-SH proteinogenic amino acid that is semi-essential. Cysteine's thiol side chain frequently functions as a nucleophile in enzyme processes.
- The sign Cyz is occasionally used when a deprotonated catalytic residue is present.
- The sign Cym can also be used to usually denote the deprotonated form.
- The thiol is capable of being oxidized to produce the disulfide derivative cystine, which is crucial for many proteins' structural integrity. Cyx is sometimes used in this context. It carries the E identifier E920 when added to food.
- The codons UGU and UGC encode the amino acid cysteine.
- Cysteine and methionine, which contain sulfur, are more quickly oxidized than other amino acids.

Empathy is a feeling that, in short, represents the ability to put yourself in the other person's shoes. This encompasses thoughts, actions or feelings regarding whatever subject is being addressed.
<h3>Can evolution explain the types of primates in the group into which they will organize themselves?</h3>
As they age, the saddles become larger and eventually cover most of their backs. The most common social group pattern among semi-terrestrial primates is the multimale-multifemale group. With this pattern, there are no stable heterosexual bonds--both males and females have a number of different mates.
<h3>How is Homo sapiens different from other non-human primates?</h3>
Upright posture, arms shorter than legs, extraordinary brains. While the natural "lottery" acted on these and other characteristics, primitive man climbed a new rung of the evolutionary scale. "In evolutionary terms, it is important to think that it is not adaptation that arises to respond to environmental needs; a variation happens and the environment ends up favoring it"
With this information, we can conclude that We are all descendants of Homo sapiens that originated in Africa. Thanks to genetics, we know that all Homo sapiens are descended from an African woman who lived about 200,000 years ago.

Clean or green energy helps in releasing lesser air pollution and lesser carbon dioxide. That contributes in lowing down global warming and subsequent disasters like tsunami because of glacier melting , more unexpected climate changes like unexpected long-period storms, flood, typhoons, etc.
Hope this would help.
The correct answer among the choices listed above is option D. The connection between the mother and the embryo that provides the embryo with oxygen and nutrients and waste disposal is the placenta. Hope this answers your question. God Bless.
