Answer:
Choice B
Explanation:
"Permeable" means "Letting solids or liquids through (a material.)" "Semi" means "half or partly." So "semipermeable" means allowing some objects through, but not all.
Answer:
Cells are considered the basic units of life in part because they come in discrete and easily recognizable packages. That's because all cells are surrounded by a structure called the cell membrane — which, much like the walls of a house, serves as a clear boundary between the cell's internal and external environments.
Answer:
The following might explain the lack of cloud formation
- The air package never reaches its dew point.
- There are too few aerosols present in the air package.
<u>Explanation</u>:
For the formation of the cloud the air in the higher position should have much colder than that of the surface. The vapours travels till it reaches the point where it has lower temperature as well as the pressure so that the water will condense into the droplets which will result in the formation of the cloud. When those vapours condenses to the liquid or to the solid it will release some of it energy to the air. For the formation of the cloud three things are mandatory and they are moisture, cooling air and the condensation nuclei. Also, for the formation of clouds, suspended particles like aerosols are required for the water to condense. As there are few aerosols, water doesn't get to condense.
Answer:
parasitism
mutualism
commensalism
Explanation:
Commensalism is defined as a relationship between two living organism in which one organism get benefits and the other organism neither benefit nor harm.
Herbivory is defined as the relationship between organisms and plants in which organisms consume plant material.
Mutualism is defined as the relationship between two living organism in which both organisms benefit each other.
Parasitism is defined as the relationship between two living organism in which one organism get benefits and the other organisms get harmed.
So, a flea and dog are an example of parasitism, certain bacteria live in the digestive tract of humans is an example of mutualism, and relationship between cattle egrets and an elephant is an example of commensalism.
Hence, the correct answer is:
parasitism
mutualism
commensalism
