Question

1. which molecule has a central carbon atom with four different components around it? 6. three of these components are the same for each molecule, what are they? a)

b)
c)

1. which molecule has a sugar, nitrogenous base, and phosphate group? 8. what are some similarities among all four types of molecules? list as many as you can. 9. what is the chemical formula of the first carbohydrate molecule shown? cho__

Explanation:

Step1: Answer question 5

A molecule with a central carbon atom having four different components around it is an amino - acid (in the context of biological molecules).

Step2: Answer question 6

In amino - acids, three common components are amino group ($-NH_2$), carboxyl group ($-COOH$), and hydrogen atom ($-H$).
a) Amino group ($-NH_2$)
b) Carboxyl group ($-COOH$)
c) Hydrogen atom ($-H$)

Step3: Answer question 7

A nucleotide has a sugar, nitrogenous base, and phosphate group.

Step4: Answer question 8

Similarities among different types of biological molecules (e.g., amino - acids, nucleotides, carbohydrates etc.):

• They all contain carbon, hydrogen and oxygen.
• They are all organic molecules.

Step5: Answer question 9

Without seeing the specific carbohydrate molecule, a general simple carbohydrate (monosaccharide) like glucose has the chemical formula $C_6H_{12}O_6$. But without the actual molecule shown, this is a general example.

Answer:

1. Amino - acid
2. a) Amino group ($-NH_2$)

b) Carboxyl group ($-COOH$)
c) Hydrogen atom ($-H$)

1. Nucleotide
2. Contain C, H, O; are organic molecules
3. General example: $C_6H_{12}O_6$ (actual depends on the shown molecule)
