Antibody binding to the receptor may cause the two parts of the receptor to dimerizeantibody binding to the receptor may cause the two parts of the receptor to blank, which normally occurs when a blank binds. this would result in the activation of the cell response even in the absense of the signalling molecule.
a) true
b) false

The correct answer would be -

Blank 1) dimerize,

Blank 2) signaling molecule, and option a) true.

Explanation:

Dimerization takes place after the signaling molecules attach to the receptor. Dimerize of antibody takes place when the antibody bind to the two parts of the receptors.

Even in the absence of a signaling molecule, signal transduction occurs. It could be possible due to mimicking the interaction and activate the receptor.

Thus, the correct answer is-

Blank 1) dimerize,

Blank 2) signaling molecule, and option a) true.

sulfur dioxide

explanation: acid rain is caused by a chemical reaction that begins when compounds like sulfur dioxide and nitrogen oxides are released into the air. these substances can rise very high into the atmosphere, where they mix and react with water, oxygen, and other chemicals to form more acidic pollutants, known as acid rain.
