Chemokines act as chemoattractants. They lead <span>to the migration of immune cells to an infection site so they can target and destroy invading bodies such as microbes. Hope this helps.</span>
Freezing rain refers to the rain that falls through a shallow layer of cold temperature at zero degree Celsius or below zero degree Celsius near the earth surface. Celsius and Fahrenheit are two types of measurement that are used to measure temperature. The freezing temperature of water is zero degree Celsius. Zero degree Celsius is the same thing as 32 degree Fahrenheit.
Thus, the thermometer reading that is expected from a thermometer near the earth's surface during a period of freezing rain is 32 degree Fahrenheit.
Answer:
The conditions that would cause a molecule to diffuse from outside to inside of a structure is a higher concentration of that molecule outside and the presence of a semipermeable membrane that facilitates its passage.
Explanation:
The process by which a molecule passes from a place where it is more concentrated where its concentration is lower - crossing a semipermeable membrane - is called simple diffusion.
<u>Simple diffusion is a mechanism that does not require energy and responds to a concentration gradient</u>. When a molecule is more concentrated in a space it can enter the space where it is less concentrated
.
The cell membrane is an example of a semi-permeable membrane where the simple diffusion process occurs.
