Answer 1
Answer: Answer - A
The ratio of a child with clear skin with that of freckled skin is 1:2.
When genotype rr mates with genotype Rr, the following genotypes are expected:
Rr = clear skin dominant
rr= freckled skin

Why do all normal cells in human body have same number of chromosomes?

Answers

The reason as to why all human body cells have the same number of chromosomes is because of the process of mitosis and meiosis. 

Mitosis is the process of cell division in which body cells or somatic cells divide to yield two daughter cells with the same number of chromosomes as the parent cells. The process involves a series of steps, and results in the formation of two new nuclei each having the same number of chromosomes as the parent nucleus. The process ensures that have the same number of chromosome. In meiosis, sex cells have half the amount of chromosomes that a normal cells has and therefore when they join another, there are 46 chromosomes in the cell. 
Females have two X chromosomes in their cells, while males have one X and one Y chromosome. Mitosis; before it divides it replicates & meiosis; sex cells have half the amount of chromosomes that a normal cell has so when they join another, there are 46 chromosomes in the cell.

When working in the lab testing different pH levels of acids and bases what safety rule must you always follow?

Answers

Answer:

When anyone testing different levels of acid and bases some safety rules must be followed like:

Wear gloves: One should wear gloves while working with acids or base so that his hand remain safe from any damage by acid or base. Acid can cause burns in hand so gloves are most important to wear.

Mask: Fumes can be generate mainly by acids which can cause irritation so masks should is important to get protection from them.

Lab coat: Lab coat protects the body from any spill of acid or base and should be wear while working in lab.
