iris [78.8K]

Answer:

A.  passive transport by diffusion

Explanation:

Diffusion and osmosis are both types of passive transport. They do not require energy. Diffusion is the general term for the process. Osmosis is the diffusion of water molecules.

Many small, uncharged molecules can cross the cell membrane by diffusion. Oxygen and carbon dioxide are examples of two small molecules that pass the cell membrane by passive transport.

Larger or charged molecules require energy to cross the cell membrane. This is achieved by active transport.

What errors exist in the table below?
Vera_Pavlovna [14]

Answer:

A. spiral galaxies are not pinwheel-shaped

Explanation:

There are three types of galaxies that include spiral galaxy, elliptical galaxy and irregular galaxy.

Elliptical galaxies are round shaped as well as elongated. Elliptical galaxies have both old and new stars but mostly it contains old stars.

Spiral galaxies are pinwheel-shaped due to the regular spinning motion of dust, stars and gas around the galactic center, at speeds of hundreds of kilometers per second which allows the matter to take a  pinwheel-shape. Spiral galaxies are made up of lot of gas and dust and forms many new stars which allows the spiral galaxy to shine bright.

Irregular galaxies do not have any definite shape because of the gravitational influence of close galaxies. They also have many new stars.

Hence, the error is foudn in first sentence, where it says that spiral galaxies are not pinwheel shaped. so teh correct option is A.
