Answer:

The correct answer is - Polymer (macromolecules), monomer (building blocks

Explanation:

Polymers are comparable to the train as polymers are made up of several monomers linked together to carry more but can be removed from the polymer if required similarly the train cars that are comparable to the monomers or building block are joined together but can be taken off.

Macromolecules are polymers that are made up of joining monomers together and makes large molecules. Macromolecules like carbohydrates are made up of monosaccharides as monomers, proteins are made up of amino acids as monomer or building block, lipids are made up of fatty acids and nucleic acid are made up of nucleotides.

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.
