The correct answer is- a. They do not impair thinking.

Explanation:

Histamine is the chemical that is involved in an inflammatory and allergic response in the body. It is a neurotransmitter and also regulates immune response in the body.

Antihistamine is the drugs that block the symptoms of allergy by blocking the histamine by binding on histamine receptor. There are two generation histamine 1st generation and 2nd generation.

The first-generation histamine has a central effect which means it affects CNS but second-generation histamine can not easily cross the blood-brain barrier so its capacity to adversely affect CNS is low therefore they do not impair thinking. So the right answer is a.

a: the sheep and waste material both release carbon into the atmosphere.

the oxygenated blood then leaves the lungs through pulmonary veins, which return it to the left heart, completing the pulmonary cycle. this blood then enters the left atrium, which pumps it through the mitral valve into the left ventricle. from the left ventricle, the blood passes through the aortic valve to the aorta.

deoxygenated blood leaves through the right ventricle through the pulmonary artery. from the right atrium, the blood is pumped through the tricuspid valve (or right atrioventricular valve), into the right ventricle.
