Shallow groove on the surface of the cortex is called sulcus.

Cortex means the outer layer of an inner organ. The outer layer of the cerebrum is called cerebral cortex, where cerebrum occupies the biggest part of the brain. A human being has four lobes of the cerebral cortex which include temporal lobe, parietal lobe, occipital lobe, and frontal lobe.

Cortex has six layers of different types of neurons which are responsible for higher information processing and thinking. Cerebral cortex controls general movement, behavioural reactions, perception and visceral functions. We term the grooved layer as the brain itself.Cerebral cortex consists of large amounts of sulci and gyri(sulcus and gyri in singular). The number of gyri correlates to the processing ability of the animal.A man has big gyri compared to a rat.

____ is a class of proteins, they make metabolic reactions proceed much faster than they would have on their own
konstantin123 [22]

Answer;

-Enzymes

Enzymes are class of proteins, they make metabolic reactions proceed much faster than they would have on their own.

Explanation;

-Proteins are biological macromolecules that are diverse in shape size and function. Enzymes are biological molecules (proteins) that act as catalysts and help complex reactions occur everywhere in life. They are biological catalysts.

All enzymes are proteins by definition. But not all biomolecular catalysts are proteins. Most enzymes are proteins, although a few are catalytic RNA molecules.

Nonamiya [84]

Answer:

tt

Explanation:

Firstly, look at the oldest female shape. It would be a circle since that is female and which circle, would be the oldest one. In line one. Since the circle is white, the gene has not been carried so it must be reccessive.

tt because it is the only allele pair that would give you the gene without obtaining that trait, meaning it is reccessive.

So it would make sense that tt is the choice.

Please HELP!! Place the events 1 to 7 in order of how they happen during speciation.
hoa [83]

Answer:

6, 3, 4, 5, 7, 2, 1

Explanation:

Here, speciation occurs because the original butterfly population gets separated into two populations, each facing a different set of environmental conditions. Initially, there was just a single population of butterflies in the valley and all butterflies were able to mate with each other. A fire destroyed their habitat so they had to migrate to other areas. Some butterflies migrated to eastern side of mountain and some to western side of mountain.

Now there were two butterfly populations and they faced different environment from each other. Over the time, the populations adapted to their local surroundings and started to accumulate changes in their genome. Their gene pools started to separate from each other. Eventually they evolved into two different species. When their old habitat was restored in the valley, they returned once again. However, this time they were not able to interbreed because they were now two different species.
