Answer:

True

Explanation:

<em>The latter studies truly showed that some factors other than genetic predisposition play a role in obesity.</em>

The composition of the genome of an individual might predispose such individual to a higher risk of being obese. However, that such individual will become obese depends on some other factors, the most important being the kind of lifestyle the individual lives.

A lifestyle such as eating foods high in fat content, not eating adequate fruits, not eating eating adequate vegetables and drinking a lot of alcohol can cause someone to be obese apart from genetic predisposition.

Answers:

1. Facilitated diffusion: the process by which some molecules that are not able to pass directly through a cell membrane are able to enter the cell with the aid of transport proteins.

2. Osmosis: the diffusion of water molecules through a selectively permeable membrane.

3. Diffusion: the spreading out of molecules across a cell membrane until to they are equally concentrated.

Step-by-step explanation:

Diffusion is the spontaneous movement of molecules across a membrane from an area of high concentration to one of low concentration gradient.

Osmosis is the diffusion of water molecules across a semipermeable membrane from an area of low solute concentration to one of high solute concentration.

Facilitated transport occurs when molecules cannot diffuse directly through a cell membrane but can diffuse down a concentration gradient through transport channels in the membrane.

1) Amino acids. Option B.

2) Phosphorus. Option D.

<h3>What are proteins?</h3>

Proteins are macromolecules made up of 2 or more amino acid units linked together by peptide bonds.

According to the passage, antibiotics work by breaking down the cell water proteins of bacteria. When proteins are broken down, they are broken into their component amino acids.

Therefore, when the researchers examine the phagocyte, the presence of amino acids would be an indication of the effectiveness of the antibiotics.

Amino acids are made up of elements such as nitrogen, carbon, oxygen, and hydrogen. Thus, if the researchers examine the monomers present in the phagocytes, all these elements should be found. Except for phosphorus.
