Answer 1
Answer:

While mapping the motor cortex, researchers Foerster and Penfield found that body areas requiring the greatest control occupied the greatest amount of cortical space

The majority of the afferent fibres that enter each region of the cerebral cortex come from a single thalamic projection nucleus. This thalamocortical projection is topographically organised so that discrete thalamic volumes project to discrete fields in the cortex, while continuous thalamic volumes project to a continuous region in the cortex. A point-to-point projection could be thought of in this respect, however this oversimplification ignores the mutual overlap of thalamic fibres inside their "modular" cortical arborization zones . Because the cerebral cortex is a two-dimensional surface and the thalamus is a three-dimensional body, the topographical depiction of the thalamic projection nuclei over the cerebral cortex is a topological problem.

Hence, Foerster and Penfield found that body areas requiring the greatest control occupied the greatest amount of cortical space.

How many days does each lunar phase last? Explain your claim with reasoning.

Answers

Answer:

29.5 Days.

Explanation:

The Moon takes 27.3 days to orbit Earth, but the lunar phase cycle (from new Moon to new Moon) is 29.5 days.

7 days…because g.o.o.g.l.e said so.

I actually don’t know the reasoning but it’s definitely 7 days total.

Question 6 (1 point)Which of the following are functions of proteins?
short term energy storage
transport
build channels in cell membranes
speed up reactions
long term energy storage
structure

Answers

Final answer:

Proteins have multiple functions in living organisms, including enzymatic activity, transport, and structural support.


Explanation:

Proteins have several important functions in living organisms. They can serve as enzymes, which are molecules that speed up chemical reactions. Proteins can also act as transporters, helping to move molecules and ions across cell membranes. Additionally, proteins are essential for structural support in cells and tissues.

For example, hemoglobin is a protein that transports oxygen in the blood. It binds to oxygen molecules in the lungs and releases them to cells throughout the body. Another example is the sodium-potassium pump, which is a protein that helps maintain the balance of ions inside and outside of cells. This pump is crucial for nerve cell communication and muscle contraction.

Calculate the pI of Histidine (pKa’s = 2.3, 6.04, 9.33)6.11
7.68
3.08
2.35
4.07

Answers

Answer:

The correct answer is 7.68

Explanation:

Isoelectric point (pI) is the pH at which the amino acid has net a charge of zero. We have to choose the two values of pKa at which the neutral form of the amino acid is predominant. Histidine (Hys) is a basic amino acid. From pKa's data, we deduce:

pKa1 = 2.3 (corresponds to α- carboxyl group)

pKa2= 6.04 (corresponds to R group)

pKa3= 9.33 (corresponds to α- amino group)

Since it is a basic amino acid, the neutral form will exist between the higher pKa's values. Thus, the pI will be in a pH value between 6.3 and 9.33.

So, we have to calculate the average of pKa2 and pKa3:

pI= (pKa2+pKa3)/2= (6.04+9.33)/2= 7.68

Therefore, the pI of Hys is 7.68.
