Given: The population density of frogs in a portion of a pond is 12 frogs per square meter. The size of the entire pond is 370 square meters.
To find: The total population size of the frogs in the pond.
Method: Using unitary method of proportions
Solution:
Let p be the density of the frogs present per square meter.
Let A denote the total area of the pond.
∴ p = 12 frogs/m² and A = 370 m²
The total number of frogs in the pond is given by,
Therefore, there are 4440 frogs in the pond.
Answer:
4. Warm air from the inside moving toward the cold air outside.
Explanation:
A cold draft can be defined as the process in which a current of cold air is being drawn in from the outside. Also, it involves the process in which a current of warm inside air exits or leaves a building through an opening.
This ultimately implies that, when you open the door to your house on a cold day, you would feel a cold draft as a result of the movement between the warm air from the inside moving toward the cold air outside. The warm air that were trapped inside your house would escape through the door due to a difference between the outside (cold) and inside (warm) atmospheric pressure.
Hence, a difference in temperature and atmospheric pressure between the outside and inside air usually causes a cold draft.
<em>Additionally, air typically moves or travels from a region of high pressure to a region of lower pressure. </em>
Answer:
a.) ventilation, circulation, cellular respiration
Explanation:
a.) ventilation, circulation, cellular respiration
b.) diffusion in tissues, cellular respiration, diffusion at respiratory surface
c.) ventilation, diffusion in tissues, circulation
d.) circulation, cellular respiration, diffusion in tissues
e.) circulation, ventilation, cellular respiration
Ventilation occurs in the lungs and is the process by which carbon dioxide in the capillaries is lost to the environment while oxygen is taken in. Circulation is the process by which this dissolved oxygen is taken by the blood to tissues around the body. When this oxygen is taken to tissue, the concentration gradient allows the oxygen to be taken up by tissue. This oxygen is used as an electron acceptor (when it reduced to water) in the mitochondria during electron transport chain of cellular respiration.
