Answer:

The cell wall

Explanation:

The cell wall exists to protect the cell, maintain its shape and regulate water uptake. The cell wall is much thicker than the cell membrane, providing an extra layer of protection. In plants, the cell wall is made of fibres of the polysaccharide cellulose, which is a structural carbohydrate.

This gives organisms such as plants much more structure - e.g. they can stand upright without the need for bones. However, they lack the same flexibility that animal cells have.

You have a 16N sack of potatoes that you need to lift onto the kitchen counter. You set up a pulley system with a mechanical adv

natali 33 [55]

A force of 8 N will be required.

<h3><u>Explanation:</u></h3>

Mechanical advantage is defined as the ratio of output force from a system to the input force into the system. A machine which has the mechanical advantage more than 1 means it requires less force to give more force as output. Similarly, when the mechanical advantage for the machine is less than 1,it means more force is required to give to achieve a less one.

Here in the question, the mechanical advantage of the pulley is 2.

Output force required to pull the sack of potatoes upto kitchen is 16N.

Mechanical advantage = Output force / input force.

Or, 2= 16 / input force.

So input force = $16 / 2 =8.$

So a force of 8 N will be required to pull the pulley.

What is the relationship between matter and atoms?

Margarita [4]

Answer:

Atoms are the smallest units of matter.

Explanation:

I would suggest using Dalton's laws of matter to help you! These laws include:

1: All matter is made of atoms. Atoms are indivisible and indesctructible

2: All atoms of a given element are identical in mass and properties

3: Compounds are formed by a combination of two or more different kinds of atoms

4: A chemical reaction is a rearrangement of atoms

Hope this helps, have a great day!
