The smooth ER helps build which biomolecules?

babunello [35]

Answer:

read explanation

Explanation:

This makes sense because this portion of the endoplasmic reticulum builds lipids, or fats, rather than proteins, and thus doesn't need ribosomes. These lipids may include fatty acids, phospholipids and cholesterol molecules. if incorrect dont hate on me please

What is the greatest advantage of using different methods that result in the same outcome?

viva [34]

The advantages of using mixed method are, the pros and cons can be identified and compared for each method. Thus option B is correct.

<h3>What are advantages of using mixed method?</h3>

Mixed methods in research is an advanced form which is basically a combination of quantitative research and qualitative research.

It can help the researcher to gain a more clear and complete picture as it integrates benefits of both methods.

Mixed methods research is used in the behavioral, health, and social sciences, societal research.

Qualitative research has smaller sample size, so mixed methods research is applied for the comparative strength of externally valid quantitative research.

Mixing methods allowed to get findings in detail to the conclusion.

Using mixed methods from different data on same subject can give more credible results.

Thus option B is correct.

A factor that lends assistance to, supplements, or adds to a condition or disease is a Contributing factor.

Contributing factor- Practices used in food preparation, human actions, and environmental circumstances all play a part in the viruses' entry into or growth in food, which can result in outbreaks.

Supplements- Something that completes or adds is defined as

1.) dietary augmentation.

2.) a section that is added to or published as a continuation of a book or magazine in order to add information or fix errors.

3.) It is an angle or arc that, when added to another, produces a 180° supplement.

A researcher is studying a newly discovered gene that causes increased body weight in domesticated chickens. In a mainland popul

Dima020 [189]

Answer:

0.382

Explanation:

In solving this, let's recall the Hardy-Weinberge's equations which are as follows: p + q = 1; $p^{2} + 2pq + q^{2} = 1$ , where p represents the dominant Allele, while q represents the recessive allele. In applying this to what we want to calculate, $p^{2} = A1A1$ , 2pq = A1A2, and $q^{2} = A2A2$ .

Using the Hardy-Weinberge's equations, we can determine the number of individuals having the different types of genotype inherent in the 100 mainland chicken that was transported.

Since p + q = 1, i.e. given that allele frequency of A1 is 0.2, therefore allele frequency for A2 = 0.8 (p + q = 1).

Using $p^{2} + 2pq + q^{2} = 1$ , we would have the following:

$p^{2} = A1A1 = 0.2^{2} = 0.04$

$2pq = A1A2 = 2(0.2*0.8) = 0.32$

$qx^{2} = A2A2 = 0.8^{2} = 0.64$

Therefore, number of mainland chickens with the A1A1 genotype = 0.04*100 = 4; A1A2 = 0.32*100 = 32; A2A2 =0.64*100 = 64

The genotype frequencies for the admixed population would be the sum of that of the transported mainland chicken and that of the isolated chicken, which would be:

Genotype mainland isolated Total No of A1 allele present

A1A1 4 200 204 204

A1A2 32 400 432 216

A2A2 64 400 464 0

Total 1100 420

Therefore, allele frequency of the A1 allele in the admixed population = 420/1100 = 0.382
