Luda [366]2 years ago
5 0

Answer:

A polar molecule simply means the charges are not exactly even throughout the molecule. Some parts are slightly negative (outside the oxygen), and some parts are slightly positive (outside the hydrogen atoms). Water is polar because the highly electronegative oxygen atom attracts electrons to it, making the region around the oxygen more negative than the areas around the two hydrogen atoms. This concept is important to understand how water bonds.

Harlamova29_29 [7]

Answer:

The sequence order of the arterial vessels in the order leading from the aorta to the brain is: 2,4,5,1,3.

Explanation:

Correct Answer: In order, the sequence of vessels leading from the aorta to the brain is: 2,4,5,1,3.

2 -The brachiocephalic artery (same as brachiocephalic trunk and innominate artery) is an artery found in the mediastinum region where blood is supplied to the right arm and the head and neck

4 - The right subclavian artery arises from the arch of the aorta directly which is a branching of the brachiocephalic trunk and is on the left lies posterior to the insertion of the scalene muscle anterior on the first rib.

5 - The vertebral arteries are arteries majorly of the neck. Usually, this arteries originate from the subclavian arteries. It functions so as to supply the vertebrobasilar vascular system, thks vertebral arteries supply blood in this order to the upper spinal cord, brainstem, cerebellum, and posterior part of brain.

1- Meanwhile basilar artery carries oxygenated blood from 5 to the cerebellum, brainstem, and occipital lobes.

3 - Several arteries at the bottom (inferior) side of the brain is called Circle of Willis and it is the joining area of several arteries in the brain. Branching of smaller arteries from the Circle of Willis happens here as internal carotid arteries that supply oxygenated blood of more than 80% of the cerebrum.

If we inserted an anabolic Tryptophan (trp) operon with GFP for amino acid synthesis instead, what would happen if we grew the b
nignag [31]

Answer:

Since there is presence of excess tryptophan, the trp operon will be switched off, since the bacterial need not to synthesize.

Explanation:

Understand the following.

The trp operon is a group of gene that encode biosynthetic enzymes for the amino acid tryptophan.

The transcription gene in the operon is switched off when the tryptophan is in excess but is switched on by the bacterium when the tryptophan is low, so that more tryptophan can be produced.
