Answer: Poly-metallic nodules

Explanation: Poly-metallic nodules are generally considered to the manganese nodules, formed due to the accumulation of rocks and mineral aggregates at the seafloor, adjacent to the underwater volcanoes.

This nodules appears in concentric layers, i.e these are the layers of manganese hydroxide and iron hydroxide. They are commonly found at the sea floor and have economical importance.

When oxygen deprivation just prior to death turns off the brain's inhibitory cells, neural activity increases in the

Bezzdna [24]

As oxygen deprivation just prior to death turns off the brain's inhibitory cells, neural activity increases in the VISUAL CORTEX. This brian region processes visual sensory information.

The visual cortex is a cortical brain region whose function is to receive, interpret and process visual sensory information.

The visual sensory information that is processed in the visual cortex comes from the eye retina, which has specialized cells (photoreceptors) to receive visual information.

The visual cortex is found in the posterior pole of the occipital lobe, and primarily in its medial region.

It has been shown that oxygen deprivation in the cerebral cortex can lead to cortical blindness.

Answer:

The strat codon is AUG

Explanation:

Genetic information for the aminoacids assembly during the protein synthesis is stored in short sequences of three nucleotides named <em>codons </em>in the mRNA. Each of the codons represents one of the 20 amino acids used to build the protein. The total number of possible codons is 64, from which 61 codify amino acids -more than one codon codify for the same amino acid-. One of these amino acids is also the start point of protein synthesis. And the left three codons are stopping translation points.

The codons indicating the initiation or stop points during the translation process are:

The start codon AUG is the most common sequence used by eukaryotic cells and places near the 5´extreme of the molecule. However, other codons might be used as well. Prokaryote cells might use the codons GUG or UUG.
