Answer:

The correct answer is: A) Messenger RNA(mRNA).

Explanation:

Proteins are macromolecules of great importance that are made of amino acids. There are 20 types of amino acids and each protein has its specific amino acid sequence.

For the protein to be synthesized correctly with all of its correct amino acids in the correct order, there is a molecule that serves as a guide: the mRNA.

<u>mRNA is a single-strand-molecule that is composed of a sequence of nucleotides</u>. A codon forms from every three nucleotides (for example: AGA, or GCU), and <u>each codon codifies for an amino acid</u>. This way, the mRNA provides the right amino acids for a protein to be created and be functional to the cell.

How can scientists use vertebrate embryo development to build evidence for the claim that vertebrates are somewhat closely relat
Yuri [45]

Answer:

All early vertebrate embryos develop tails and gill slits, and therefore this type of anatomical evidence supports common ancestry  

Explanation:

Embryology is a discipline that studies the structural/anatomical features and development of embryos. Embryos are a fundamental piece of evidence to support common ancestry among vertebrates because there are homologous structural features that can only be observed during the first stages of vertebrate development. For example, all vertebrate embryos (e.g., fish, chicken and human embryos), develop tails and gill slits during their first stages of embryo development. In consequence, embryology provides evidence for evolution of vertebrates.

c. Cerebrum

Explanation:

The cerebrum is the part of the brain that is responsible for processing the sensory information, critical thinking and learning. It stores this information and processing centers make predictions for various conditions. The Wernicke’s area and Broca’s area represent the areas of language present in the cerebral cortex and are associated with language and speech.

What is one essential amino acid which cats cannot produce but dogs can?
fgiga [73]
The essential amino acid for cats but not dogs is taurine. Taurine is an amino acid that is essential in the process of metabolizing fats. Cats need twelve essential amino acids compared to eleven needed by dogs. The deficiency of this amino acid is most diagnosed in cats ad it generally leads to blindness, deafness and heart failure in felines.
