If Clark had no ions in his nervous system, ____. his action potentials would be faster his action potentials would be slower

telo118 [61]

Answer:

If Clark had no ions in his nervous system, he would not be able to generate an action potentials.

Explanation:

An action potential occurs when a stimulus causes sodium channels to open in a neuron. Sodium floods in, making the inside of the cell more negative and the outside more positive. This is known as depolarization. Then, the Potassium channels open to allow Potassium out (Repolarization). A few too many K+ ions will leave the cell (Hyperpolarization), and finally, the Sodium-Potassium pump will bring the cell back to resting potential.

As you can see, the Sodium and Potassium ions are <em>essential</em> to action potentials in the nervous system. If Clark had no ions in his system, he would not be able to send any action potentials at all.

Arachidonic acid (ARA) and docosahexaenoic acid (DHA) are two long-chain fatty acids necessary for the development of Multiple C

lana [24]

Answer:

The correct answer is: the nervous system, brain, and eyes.

Explanation:

Arachidonic acid (ARA) and docosahexaenoic acid (DHA) are long-chain polyunsaturated fatty acids that have great nutritional value, as they are omega-6 and omega-3 fatty acids, respectively, meaning they are essential fats that cannot be produced by the body and, therefore, need to be part of the diet.

The consumption of ARA and DHA has been directly linked to the development of the brain and the retina, and the inclusion of these fatty acids in the nutrition of infants has been proven to be extremely beneficial to their growth.

Besides their functions in the development of the nervous system and the eyes, ARA and DHA play a role in maintaining a healthy immune system and preventing cardiovascular conditions.

Choose the arteries in the order that an erythrocyte passes through traveling from the aorta to the brain: (1) Basilar artery, (

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.
