Atomic number, atomic mass, symbol of element
Answer:
As for what is written, I think that your wording is incomplete, since valine (abbreviated Val or V) is one of the twenty amino acids encoded by DNA on Earth, whose chemical formula is HO2CCH (NH2) CH (CH3) 2. In messenger RNA, it is encoded by GUA, GUG, GUU or GUC. Nutritionally, in humans, it is one of the essential amino acids.
Explanation:
Being an essential amino acid, it speaks of the fact that the organism does not synthesize it, therefore it must be ingested in the daily diet as well as in foods rich in proteins: red meat, chicken, fish, eggs, grains and nuts.
I believe the answer is A.... I'm going with a for this Qs.. GL
There is an unstable ratio of protons and neutrons. Because protons are positively charged but neutrons have no charge, an increase in the number of protons means there needs to be an increase in the number of neutrons to "bind" the nucleus together. This is because like charges repel, so the protons will repel each other, and if there aren't enough neutrons to act as "glue" to hold the nucleus together, the nucleus will break apart.
Answer:
Changing the pendulum design after the first trial was an example of <u>evaluating the model</u> to solve the problem presented by the teacher.
Explanation:
A model constitutes an abstract representation of a certain aspect of reality, and has a structure that is formed by the elements that characterize the aspect of the modeled reality and by the relationships between these elements.
This achieved result provides a better understanding of the problem being studied, offering aspects that can be changed or improved to solve the problem posed, obtaining more information about the reality of the phenomenon that is being represented.
