The best answer is B - Proteins.
Proteins make up enzymes, or to put it another way enzymes are made up of protein. It is enzymes that speed up the chemical reactions. Enzymes are organic catalysts, substances that speed up a (biochemical) reaction but do not take part in the reaction and remain unchanged at the end of the reaction.
In man, there are many enzymes. The majority of these are found in the digestive system where they greatly aid the process of food breakdown from complex molecules to simple molecules. Examples include salivary amylase found in saliva, which begins the gradual breaking down of starch into glucose right from the moment food is placed in the mouth and mixed with saliva. Pepsin in the stomach breaks down protein.
The answer to this question is the bladder
False. The ventricles are the two lower chambers of the heart.
<h3>Structure of the heart</h3>
The human heart consists of 4 chambers, namely:
- The right atrium
- The left atrium
- The right ventricle
- The left ventricle
The two atria are located on the upper part of the heart and are, therefore referred to as the upper chambers of the heart while the two ventricles occupy the lower part are known as the lower chambers of the heart.

Answer:
Land and sea breezes are wind and weather phenomena associated with coastal areas. A land breeze is a breeze blowing from land out toward a body of water. A sea breeze is a wind blowing from the water onto the land. Land breezes and sea breezes arise because of differential heating between land and water surfaces.
Explanation:
Land breezes come from land while sea breezes come from the ocean or other large bodies of water. While a land breeze is formed at night, a sea breeze is formed at daytime. Land breezes are more often experienced during autumn and winter while sea breezes often occur during spring and summer months.
