There are choices for this question namely:
<span>A) B cells produce IgE antibodies
B) B cells release cytokines
C) cytotoxic T cells present the class II MHC molecule-antigen complex on their surface
D) helper T cells release cytokines
The correct answer is "helper T cells release cytokines". Cytokines are released by helper T cells when B cells attach to them via receptors. These T cells "help" these B cells to differentiate by secreting certain cytokines. When B cells differentiate, they are converted to plasma cells and able to secrete antibodies to the antigen presented to the T cells. </span>
Answer:
Waves interact with matter in several ways. The interactions occur when waves pass from one medium to another. Besides bouncing back like an echo, waves may bend or spread out when they strike a new medium. These three ways that waves may interact with matter are called reflection, refraction, and diffraction.

The citric acid cycle, also known as the Krebs cycle or the tricarboxylic acid cycle, is at the center of cellular metabolism, playing a starring role in both the process of energy production and biosynthesis. It finishes the sugar-breaking job started in glycolysis and fuels the production of ATP in the process.
Answer:
Mist is made of water vapor.
Explanation:
The bathroom mirror and the fog that the bathroom presents after someone takes a shower, is formed by water vapor. This water vapor is formed by the hot water from showers, which evaporates. This water vapor is what forms the mist, however, when this mist touches the surfaces of the bathroom, such as the mirror, it becomes water again and that smothers the mirror. The mist becomes water when touching the mirror because of the difference in temperature between them, as the mist is hot and the mirror is cold. This happens through the condensation of water.
