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.

Neurons function to process and transmit information. In vertebrate animals, neurons are the core components of the brain, spinal cord, and peripheral nerves.
Answer:
Biodiversity hotspots are regions under surveillance of humans where threatened and endemic species of flora and fauna are grown. These regions have been identified as some of the world's most important ecosystems.
The two criteria for designation as a biodiversity hotspot are:
1. It must possess at least 1500 vascular plant species as endemics : It means the region must have a high percentage of plant species which are found no where else in the world.
2. It must have 30% or less native vegetation : It means that the plant species population is endangered and threatened to extinction.
The nervous system is the major controlling, regulatory, and communicating system in the body. It is the center of all mental activity including thought, learning, and memory. Together with the endocrine system, the nervous system is responsible for regulating and maintaining homeostasis.
