Which of the following is an example of condensation in the water cycle? a. the formation of icebergs b. the formation of ground water c. the formation of water vapor d. the formation of clouds

The right answer is: D. the formation of clouds

Condensation is the second stage of the water cycle. The water vapor circulating in the atmosphere will encounter a colder air and it will turn into droplets, this phenomenon is called condensation.
Water droplets accumulate in the form of clouds of different shapes, density, and altitude. This phenomenon is called condensation. Water vapor travels on the surface of the earth in the form of clouds.

answer: - b cells

explanation: -

there are many types of white blood cells present in our body. one such class of white blood cells are the lymphocytes. the b cells belong to the lymphocyte class of wbcs. the b cells perform their action against the pathogen by producing specialised proteins called as antibodies. these antibodies are produced as and when the b cells encounter pathogens in response to the antigens present on the surface of the pathogen. these antibodies bind to the antigens present on the pathogen and then, target them for destruction by other cells of the immune system.

so, the b cells mediate their action by identifying the antigens present on the surface of the pathogens and then producing antibodies in return to mediate its effect.
