You call to a friend from a boat floating in the ocean. Which best describes the changes in the speed of the sound waves as they

Alina [70]

The correct answer is: The speed of sound is faster in the water than in the air.

The speed of sound is different between those two mediums because they have different densities. Since, water is denser than air, more energy is required to generate a wave but once it stars, it travels faster than it would do in air. Sound waves’ travel can be presented by particles that transmit the energy one to another as they bump. The sound speed is lower in the air (than in water) because particles are far apart, so they travel further before they collide.

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.
