<em>Davy made a model of the water cycle by adding some water inside a plastic bag, sealing the bag, and placing it in a sunny area. He noticed that the level of the water went down, and then some droplets appeared on the sides of the bag. which part of the water cycle caused water droplets to form on the side of the plastic bag? </em>
<em>(a) condensation (b) evaporation (c) precipitation runoff</em>
The part of the water cycle that caused water droplets to form on the side of the plastic bag would be condensation.
<h3>What is condensation?</h3>
It is a process whereby water vapor in the atmosphere condenses or turns back into liquid.
Condensation is as opposed to evaporation. The latter is a process whereby liquid water turns into vapor water. In other words, evaporation and condensation are words and opposites.
Both processes play a major role in the water cycle of the ecosystem.

Answer:
Something that an antibody or T-lymphocyte binds to
Explanation:
As per the definition, antigens are the substances or molecules that are capable of inducing an immune response. When our immune system detects any unwanted substance or molecule in our body, the specific type of antibody is made against that antigenic substance and the antibody made against it binds to the antigen so that the other immune cells can recognize it and destroy it and protect us form its harmful effect. T-cell are also involved in recognizing antibodies and specific T-cell can bind to the antigen.
