Answer:

B. a ventral horn

Explanation:

In the medulla, the gray matter is located inside the white and is shaped like a butterfly or an "H". In it we distinguish on each side three columns that appear in the cuts as horns and which are the anterior, posterior and lateral columns. The lateral spine only appears in the thoracic medulla and part of the lumbar medulla. In the center of the gray matter is the central canal of the medulla.

The human brain communicates with the rest of the body through networks of what?

True [87]

Through nerves attached to the brain and to the spinal cord. When an action potential traveling down the axon reaches a terminal button, they secrete a chemical called a neurotransmitter.

The brain communicates with the rest of the body through the spinal cord, which runs from the base of the brain all the way down the back. The spinal cord is made up of lots of nerves, and these nerves branch out into more nerves that travel to every part of the body.

Which of the following would be LEAST likely in the fossil record? Which of the following would be LEAST likely in the fossil re

GREYUIT [131]

Answer:

The correct answer is desert-dwelling species.

Explanation:

Any preserved remains, trace or impression of anything, which was once living in the past is termed as a fossil. The examples of fossils comprise stone imprints of microbes or animals, bones, exoskeletons, shells, coral, remnants of DNA, the substances getting preserved in amber, and others.

For the formation of fossils, the most essential condition is decomposition that takes place gradually, that is, at a slow pace. Thus, places like wet marshy areas will be the locations where the maximum of the fossils can be found as such places provide optimum conditions for slow mineralization and decomposition of bones.

On the other hand, places like deserts would be the least likely to have a fossil record as deserts are devoid of optimum conditions required for the formation of fossils. In places like a desert, decomposition and demineralization of the components like bones take place at a brisk rate.

Beriberi is caused by a deficiency of thiamine in the diet.

denis23 [38]

Answer:

Thiamine pyrophosphate (derived from vitamin B1) is a coenzyme required for the activity of pyruvate dehydrogenase enzyme complex.

Explanation:

Pyruvate is the end product of glycolysis. During aerobic cellular respiration, pyruvate is oxidatively decarboxylated into acetyl CoA which in turn enters the Kreb's cycle. Oxidative decarboxylation of pyruvate is carried out by enzyme complex pyruvate dehydrogenase (PDH). The first step is simple decarboxylation and is catalyzed by pyruvate decarboxylase of the PDH complex.

The enzyme pyruvate decarboxylase and has a tightly bound coenzyme, thiamine pyrophosphate. Thiamine pyrophosphate is derived from vitamin B1. Lack of vitamin B1 in the human diet leads to beriberi that is characterized by an increased concentration of pyruvate in blood urine since oxidative decarboxylation cannot occur due to lack of the coenzyme thiamine pyrophosphate.

What events occur during high tide

makkiz [27]

Answer:

The tidal force causes Earth—and its water—to bulge out on the side closest to the Moon and the side farthest from the Moon. These bulges of water are high tides. As the Earth rotates, your region of Earth passes through both of these bulges each day. When you're in one of the bulges, you experience a high tide.

Match each structure on the left with the corresponding function on the right. Group of answer choices Chemically digests food,

Ad libitum [116K]

Answer:

1. Chemically digests food, absorbs nutrients and minerals from food - Small intestine

2. Breaks down and physically digests food - Stomach

3. Metabolizes nutrients, detoxifies blood, makes bile - Liver

4. Stores and concentrates bile - Gallbladder

5. Removes waste products and excess fluid - Kidney

6. Filtering structure of kidney - Nephron

7. Produces eggs and reproductive hormones - Ovary

8. Produces sperm and reproductive hormone - Testis

Explanation:

This question is asking to correctly match certain digestive organs with their respective function. The organs and their function are as follows:

- Small intestine: Small intestine is the major organ that digests food chemically, and also absorbs nutrients and minerals from food.

- Stomach: This breaks down and physically digests food.

- Liver is responsible for metabolizing nutrients, detoxification of blood, and making of bile.

- Gall bladder is a greenish yellow organ responsible for the storage and concentration of the bile produced by the liver.

- Kidney is the major excretory organ of the body, which removes waste products and excess fluid from the body.

- Nephrons are numerous filtering structure of the kidney.

- Ovary is the female reproductive organ that produces the eggs/ova and other reproductive hormone like oestrogen.

- Testis is the male reproductive organ that produces the sperm and other reproductive hormone like testosterone etc.
