Answer:

It is important for the cell to be able to bring necessary nutrients immedriately where it needs to and to be able to dispose of harmful byproducts of the cell process. It is equally important to be able to regulate water concentration.

Answer:

For the first question, you have to first understand how cells work. Cells transport nutrients and water through their cell membrane, and it's their only way of transporting things they need in and out of their interior. Hence, a larger surface area would be best for cells to survive.

You might ask, but then why wouldn't it be better for cells to be bigger if a larger cell membrane is beneficial to their survival? After all, as the cell gets bigger, their cell membrane gets bigger too!

Unfortunately, you'd be forgetting one thing: the insides of the cell, otherwise known as the volume of the cell, grows too. So, it becomes a mathematical question at this point: imagine a cube. If you doubled it's side length, your surface area would grow by 4 times (2x \cdot 2x = 4x^{2}), and your volume would grow by 8 times! (2x \cdot 2x \cdot 2x = 8x^{3})

Hence, if the cell got bigger, it's volume would grow faster than the surface area, and the cell would start to build up carbon dioxide and other waste materials.

This is the main reason why being small helps cells survive. Of course, there are many other reasons, like compactness, efficiency and survivability, but this is the main reason.

Of course, if you're smart, you'd have already discovered one thing: this is exactly the reason for your second question as well. Since a large organism being made of one or few large cells would greatly decrease surface area-to-volume ratio, the efficiency would plummet and the large organism would die. Hence, many small cells would help large organisms maintain homeostasis.

Stroke volume is the amount of blood that leaves the left ventricle of the heart with each contraction. If a person has a stroke
makvit [3.9K]

Explanation:

The amount of blood that leaves the left ventricle of the heart with each contraction is called Stroke volume.

A person has a stroke volume of 80 ml/beat. It means that it is 80 milliliters per beat.

We need to find how many liters would that be.

We know that, 1 litre = 1000 milliliters

1 mL = 0.001 L

To convert 80 mL to litres, we can do it as follows :

80 mL = (80 × 0.001) LL

= 0.08 L

Hence, he stroke volume of a person is 0.08 L/beat.
