In sheep, white is due to a dominant gene (W), black to its recessive allele (w). A white ewe mated to a white ram produces a bl
dedylja [7]

Answer:

Yes, 75%

Explanation:

Since the first offspring produced between the ram and the ewe was black you can determine that both sheep have a recessive and dominant allele. Both of the parent's genotypes would be Ww, this is because they both have the white phenotype and they were able to produce a black offspring. Since both parents have a genotype of Ww the probability of a black offspring being produced is 25% and 75% for a white lamb.

The concentration of cholesterol (C27H46O) in blood is approximately 5.0mM. How many grams of cholesterol are in 315mL of blood
ASHA 777 [7]

The weight of cholesterol is 0.6 g.

Here use the concept of molarity.

<h3>What is molarity?</h3>

The amount of a substance in a specific volume of solution is known as its molarity (M). The moles of a solute per liter of a solution is known as molarity.

Molarity = no. of moles/volume (in L)

<h3>Calculation:</h3>

Given,

Molarity, M = 5.0 mM = 5 × 10⁻³ M

Volume, V = 315 mL = 315 × 10⁻³ L

To calculate,

Weight of cholesterol =?

We know that,

Molecular mass of cholesterol, C₂₇H₄₆O = 386

No. of moles = weight/ molecular mass

The formula is modified as,

Molarity = weight of cholesterol/ (molecular mass) (Volume)

Put the values in the formula,

5 × 10⁻³ = weight of cholesterol/ (386) (315 × 10⁻³)

Weight of cholesterol = 5 × 10⁻³  (386) (315 × 10⁻³)

                                    = 0.6 g

Hence, the weight of cholesterol is 0.6 g.

For each of the following
labwork [276]

Answer:

A-Both

B-Unknown but you said it was fine

C- mitosis

Explanation:

Mitosis and meiosis both have interphase, in which dna is replicated (synthesis). B I don’t know, hopefully you can get that one figured out—sorry :(. Meiosis occurs twice, which is why it results in 4 cells (gametes). Hope this helps a little :)
