Answer:

The correct answer is: It allows large masses of food to pass through the esophagus when swallowing.

Explanation:

The trachea, or windpipe, is a hollow organ that <u>connects the larynx to the bronchi and allows the passage of air</u> so it can reach the lungs and make the gas exchange possible.

The trachea has cartilages around it to reinforce the tube for protection and to maintain the airway open. The places where there's cartilage are the anterior and the lateral sides of the trachea. This cartilage has the shape of an incomplete ring, or the shape of a C to allow the passage of food. The side that has no cartilage is the posterior side of the trachea, which is the side that is <u>in relation to the esophagus</u> - the part of the gastrointestinal tract that transports the food from the buccal cavity to the stomach.

Answer:

1. While Biology is the study of living things, living things themselves are made up of chemical composition. Our survival is dependant on the reactions taking place inside and outside the body. Hence, to understand living things, biologists needs a good understanding of chemistry.

2. 170 pm is the radius of a Carbon Atom.

3. The vast majority of the mass of an atom is concentrated in its nucleus

4. Protons are found in the nucleus of the atom. This is a tiny, dense region at the center of the atom. Protons have a positive electrical charge of one (+1) and a mass of 1 atomic mass unit (amu), which is about 1.67×10−27 kilograms.

5. Neutrons are located with protons in the nucleus; they too exchange mesons with protons and with each other to form the strong nuclear force, but they do not have to overcome the repulsion from Coulomb forces since neutrons are not charged.

12345 [234]

Answer:

The correct option is C: antigen-binding sites

Explanation:

The antibody is shaped much like the letter Y in the English alphabet. It has two antigen binding sites that are identical in nature. The specificity of these sites is determined by the amino acid sequence that makes it up. Antibodies are complementary to these antigen binding sites, and the antibodies have an incredible ability to recognize a great variety of antigens.

Hope that answers the question, have a great day!
