Assume that the red blood cell counts of women are normally distributed with a mean of 4.577 million cells per microliter and a
postnew [5]

Answer:  C. ​82.26%

Explanation:

Given :  The red blood cell counts of women are normally distributed with

\mu=4.577\text{ million cells per microliter}

\sigma=0.382\text{ million cells per microliter}

Let X be the random variable that represents the red blood cell counts of randomly selected woman.

Z-score : z=\dfrac{X-\mu}{\sigma}

For X=4.2

z=\dfrac{4.2-4.577}{0.382}\approx-0.99

For X=5.4

z=\dfrac{5.4-4.577}{0.382}\approx2.1544

Now, the probability that the women have red blood cell counts in the normal range from 4.2 to 5.4 million cells per​ microliter will be :-

P(4.2

Hence, 82.26% of women have red blood cell counts in the normal range from 4.2 to 5.4 million cells per​ microliter.

An experiment is designed to determine if wheat grows better when it is planted alone or with clover. The design calls for 3 pan
Viktor [21]

Answer: Option B

Explanation:

Usually in scientific experiments, at least one parameter is checked; here, the growth rate of wheat in two different conditions is being evaluated.

Hence, growth rate of wheat alone in pans A, B and C becomes the standard or referential control against which the experimental control (Wheat + clover) in pans D, E and F is evaluated, since both treatments are exposed to the same external conditions.

I hope this helps

Which hormones are involved in building and maintaining healthy bone tissue? select all that apply?
gavmur [86]
Answer;
Insulin and the growth hormone
The hormones that are involved in building and maintaining healthy bone tissues are Insulin and growth hormone


Explanation;
Insulin has some anabolic properties for bone. It is uncertain whether insulin stimulates bone directly or indirectly by increasing muscle work and thus skeletal loading. 
Growth hormone is a peptide hormone secreted from the pituitary gland under the control of hypothalamus. It directly and through IGF-I stimulates osteoblast proliferation and activity, promoting bone formation. Additionally it stimulates osteoclast differentiation and activity,promoting bone resorption.
