Answer:

a) is present in honhuman primates but not humans, because humans lost this feature.

Explanation:

The opposable big toe is a trait that helps to primates to climb trees easily. Humans' ancestors started to walk in two legs, this created a needing for better stability, so a fixed toe became to evolve to allow our bipedal locomotion.

Therefore, options b and c are wrong. Option d is wrong too because it implies that the group "primates" is newer than "humans", and in fact, "humans" is part of the group "primates", so this is not the correct answer.

Stells [14]

A person does have basic human rights and one is the freedom of expression. Though this is the case, we should understand that our right to freely express ourselves (from political to religious views), it does not necessarily give us the right to impede another person’s. A play with words can easily hurt or even harass other people, and in return may be a form of human right violation.

Of the answers below, what is the smallest nucleotide sequence that could code for a protein with 300 amino acids?
ololo11 [35]
The nucleotide sequence would have to have 900 nucleotides in order to code for a protein of 300 amino acids. When translating RNA into proteins, RNA is read 3 bases at a time. Each group of 3 bases is a codon, and each codon codes for an amino acid. When read, the proper amino acid is added to a growing chain of amino acids, which will be folded to become a protein.

Therefore, 300 amino acids * 3 nucleotides per amino acid = 900 nucleotides.
