madam [21]3 years ago
3 0
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>

Pepsi [2]

Answer:

Acid deposition-usually referred to simply as acid rain-actually includes two forms of pollution, wet and dry. ... In the wet type of acid deposition, these compounds combine with water vapor in the atmosphere to form highly corrosive sulfuric and nitric acids.

Explanation:

The accumulation of acids or acidic compounds on the surface of the Earth, in lakes or streams, or on objects or vegetation near the Earth's surface, as a result of their separation from the atmosphere. Acid deposition can harm the environment in a variety of ways, as by causing the acidification of lakes and streams, the leaching of minerals and other nutrients from soil, and the inhibition of nitrogen fixation and photosynthesis in plants.♦ The accumulation of acids that fall to the Earth dissolved in water is known as wet deposition. Wet deposition includes all forms of acid precipitation such as acid rain, snow, and fog.♦ The accumulation of acidic particles that settle out of the atmosphere or of acidic gases that are absorbed by plant tissues or other surfaces is known as dry deposition.

Which of the following is true of receptors for dynamic equilibrium?
gulaghasi [49]

Answer:

The correct answer is option D.

Explanation:

Dynamic equilibrium refers to the sense, which interprets angular acceleration in the three-axis of rotation that when combined provides a sense of equilibrium when movement takes place. The receptors for dynamic equilibrium are known as ampulla, maculae are the receptors of static equilibrium.  

The movement of the head does stimulate dynamic equilibrium receptors, as these receptors are situated in the inner ear that moves with the head. The receptors for dynamic equilibrium are situated in the semicircular canals. The receptors for dynamic equilibrium react to rotational forces, as the receptors are located on the three-axis, thus, they can detect rotation, that is, angular momentum.
