Answer: Metabolic rate is the total amount of energy an animal uses in a unit of time
Explanation:
Hi, metabolic rate is the total amount of energy an animal uses in a unit of time.
It refers to how quickly fuels are consumed to keep the organism’s cells functioning.
Its unit of measure can be Joules, calories or kilocalories per unit of time.
Metabolic rate is proportional to the activity level. The More active the animals is , the higher the metabolic rate is.

Answer:
Interestingly, some cells in the body, such as muscle cells, contain more than one nucleus ((Figure)), which is known as multinucleated. Other cells, such as mammalian red blood cells (RBCs), do not contain nuclei at all.

Meiosis occurs only in reproductive organs
Air moves into the lungs when the air pressure in the lungs is lower than the air pressure outside of the lungs. This occurs when the muscels of the diaphragm contract.
You can see this by breathing in and out deeply. When you breath in you can feel your chest being pushed up and out by your diaphragm. The reason the pressure in the chest is lower is that when you breathe in you are increasing the volume of your chest. As there is the same amount of air in your chest the pressure decreases.
Answer:
The correct answer is B. In the human eye, the greatest amount of refraction occurs when the light passes from the air into the cornea.
Explanation:
The ocular refraction refers to the refraction that occurs in the light coming from the objects when crossing the different parts of the eye, causing the images to concentrate on the retina.
When the light rays, after crossing the cornea and the lens, are projected on the retina at a single point creating a clear image that is transmitted to the brain for processing, we talk about normal refraction.
