Answer:
C. 1,024
The answer can be worked out using 2^pairs of chromosomes
Explanation:
Imagine there were <u>two</u> pairs of chromosomes:
- A paired with B
- C paired with D
A gamete could have the following combinations:
Therefore, with two pairs of chromosomes, there are 4 (2²) possibilities
Now, Imagine there were <u>three</u> pairs of chromosomes:
- A paired with B
- C paired with D
- E paired with F
A gamete could have the following combinations:
- A + C + E
- A + D + E
- A + D + F
- A + C + F
- B + D + F
- B + C + F
- B + C + E
- B + D + E
Therefore, with three pairs of chromosomes, there are 4 (2³) possibilities
For 10 chromosomes - there are 2¹⁰ possibilities. 2¹⁰ = 1024

Answer:
Bile, informally known as stomach acid, chemically breaks down food early on in the digestive process.
Explanation:
Chewing is the first step in the process of digestion (assuming we are talking about humans and other animals with a similar digestive system) where the food is mechanically/physically broken down.
At the same time, saliva breaks down the food chemically (hence why leaving a simple carb such as bread in your mouth causes it to dissolve over time)
Once you swallow, muscles in the esophagus push the broken-down food to the stomach, where more chemical digestion takes place as a result of bile.
Chromium is a micro-nutrient. The role of the chromium is to maintain carbohydrate metabolism at a molecular level. For optimum activity of insulin, chromium is required. It auto amplify insulin signalling. Insulin regulates blood glucose (carbohydrate) thus, chromium participates in the metabolism of carbohydrate.
