3. phospholipids are important for forming cell membranes.
4. the ratio of carbon, hydrogen, and oxygen in carbohydrates is always 1:2:1.
5. proteins can be found in foods such as fish, eggs, and meat.

Question

Accepted Answer

### 1. Proteins are made of nucleotides.
# Brief Explanations:
Proteins are made of amino acids, while nucleotides are the building blocks of nucleic acids (DNA, RNA). So this statement is false.
# Answer: FALSE

### 2. Steroids are a type of carbohydrate.
# Brief Explanations:
Steroids are a type of lipid (they are hydrophobic and have a characteristic ring structure), while carbohydrates are a different class of biomolecules (composed of carbon, hydrogen, oxygen in a 1:2:1 ratio generally). So this statement is false.
# Answer: FALSE

### 3. Phospholipids are important for forming cell membranes.
# Brief Explanations:
Cell membranes are primarily composed of a phospholipid bilayer. Phospholipids have a hydrophilic head and hydrophobic tails, which arrange to form the membrane structure. So this statement is true.
# Answer: TRUE

### 4. The ratio of carbon, hydrogen, and oxygen in carbohydrates is always 1:2:1.
# Brief Explanations:
While many simple carbohydrates (like glucose, $C_6H_{12}O_6$) have a 1:2:1 ratio of C:H:O, some carbohydrates (like deoxyribose in DNA, $C_5H_{10}O_4$) do not follow this exact ratio. So the "always" in the statement makes it false.
# Answer: FALSE

### 5. Proteins can be found in foods such as fish, eggs, and meat.
# Brief Explanations:
Fish, eggs, and meat are rich sources of protein. These foods provide dietary protein which is used by the body for various functions. So this statement is true.
# Answer: TRUE
