How many atoms lined up side by side would equal the thickness of a book page?

1 answer:

3 0

More than 1 million atoms lined up side by side would equal the thickness of a book page. The modern atomic theory was proposed in 1803 by English chemist John Dalton. His premise is based on the fact that all elements are composed of atoms. An atom is defined as the smallest part of an element. It also keeps the identity of the element. Individual atoms are very small. Most elements in their pure form exist as individual atoms. Some elements are made up of groups of atoms.

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.

A capillary is a tiny blood vessel where:

maks197457 [2]

It is useful for the walls of capillaries to consist of a single layer of thin, flattened cells in order to easily diffuse oxygen and nutrients easily from the blood and into the capillaries. Not only that, but this also makes it more efficient for carbon dioxide and other waste molecules to diffuse from the capillaries and into the blood. If capillaries were thicker than a cell, then it would be more difficult for materials to diffuse through the thick layer of cells.
