Answer:
Simple diffusion is responsible for the spread of an air freshener through a room, or of a few drops of dye to eventually turn a glass of water a uniform color. Molecules naturally disperse from areas of higher concentration to lower concentration.
As oxygen-rich (and carbon dioxide-poor) blood travels by a cell the oxygen diffuses through the cell membrane to the area of lower concentration inside the cell. It can do this easily because the oxygen molecule (O2) is very small and has no charge or polarity. The oxygen is used up rapidly by mitochondria. This rapid consumption causes oxygen to constantly move into the cell from the blood.

What is happening to the growth of a population in which death rate equals birthrate, but emigration is greater than immigration?
Answer:
Explanation:
A negative growth rate means it is decreasing. The two main factors affecting population growth are the birth rate (b) and death rate (d). Population growth may also be affected by people coming into the population from somewhere else (immigration, i) or leaving the population for another area. i mean
The growth of the population is decreasing.
Growth rate of the population depends upon:--Birth rate
-Death rate
-Immigration
-Emigration
What is emigration?Movement of organism from its residing place to another place.This generally happen because of certain factors like not suitable habitat, occupation, food, etc.To know more about growth rate here

What are the three kinds of muscle tissues? Where is each located?
Answer:
Cardiac, smooth, and skeletal muscle tissues.
Explanation:
Muscle tissue is classified into three types: cardiac, smooth, and skeletal. Cardiac muscle cells are found in the heart's walls, are striped (striated), and are under involuntary control. Except for the heart, smooth muscle fibers are found in the walls of hollow visceral organs (such as the liver, pancreas, and intestines), are spindle-shaped, and are similarly under involuntary control. Skeletal muscle fibers are found in muscles that are connected to the bones. They have a striated look and are controlled voluntarily.

4. Some early mornings , dew drops can be found on grass or a car parked outside,
but not on other materials such as the sidewalk. Why is that?
the nighttime temperature on grass and the car went below the dew point, but
the temperature of the concrete did not drop enough to reach the dew point
level
temperature on the grass and sidewalk were both above the dew point levels all
night
the relative humidity of the air above the grass was higher than it was above the
concrete
none of the above
Dew drops can be found on grass or a car parked outside but not on other materials such as the sidewalk because; The nighttime temperature on grass and the car went below the dew point, but the temperature of the concrete did not drop enough to reach the dew point level.
Definition:
The dew point is simply defined as the temperature below which the water vapour in a given volume of air at a constant pressure will condense into liquid water. More specifically, the dew point is the temperature at which the air is saturated with moisture.From the definition above, it is evident that the fact that the nighttime temperature on grass and the car went lower than the dew point temperature is responsible for the condensation of water vapour on grass and the car as opposed to the case in Concrete.
