Color blindness is a recessive trait. The gene for color blindness is on the X-chromosome. The family tree below shows the trait of color blindness. The only unknown is the mother in the first generation. What is true about the mother?

Answers

The true statement about the mother of this family tree is that she is a carrier for color blindness.

The correct option is (B).

What is color blindness?

Color blindness is a disability in which you are unable to see colors normally. Color deficiency is another name for it.

It is a condition in which a person is unable to distinguish between different colors.

The most common colors are greens and reds, but it can also happen with blues.

This condition is only dominant in males, but females carry this disability as recessive carrier, so they can transfer this gene to the next generation.

Thus, option (B) she is a carrier for color blindness is correct.

B,

since males only need one recessive trait for it to show, and the father is not colorblind, the mother at least has to be a carrier for the colorblindness trait.

In cells, __________ are proteins that are needed to lower the amount of energy required to start chemical reactions.a. acids
b. enzymes
c. products
d. substrates

Answers

Answer:

b. enzymes

Explanation:

For any reaction to happen, an energy barrier must be crossed first. This is called as activation energy. Enzymes are biological catalysts that lower the activation energy for a reaction. As a result the reaction is started sooner and its rate is fast.

The substrate binds to the active site of enzyme to form a substrate-enzyme complex. The reaction takes place and product is formed also releasing the enzyme back so that it can be used again.  
The answers would be B.
Enzymes accelerate or catalyze ( slow or stop) chemical reactions. And enzymes are protein molecules.
While A, C, and D are not.
