After reading about the scientific method, explain why it's important to follow the steps outlined in the scientific method care

fully. How can researchers prevent mistakes and errors in their experiments? A good answer should include the following: Importance: So that the results would be due to the specific variables tested and not due to something else So that other researchers could follow the steps and carry out the same experiments Prevent mistakes: Carefully selecting variables Following the steps outlined in the procedure Carefully and accurately measuring quantitative data

Answer:

It's important to follow the steps outlined in the scientific method carefully

so that the results would be due to the specific variables tested and not due to something else. Not only that but this also allows  other researchers to follow the steps and carry out the same experiments.

Researchers can prevent mistakes and errors in their experiments by

carefully selecting variables,  following the steps outlined in the procedure and  carefully and accurately measuring quantitative data

In animals, the inability to make the pigment melanin results in albinism, a recessive autosomal condition. Two unaffected paren
Fittoniya [83]

Answer: 1/16, or approximately 6.25% (see explanation below)

Explanation:

Answering this question requires two steps.

First, we need to figure out the probability that this couple will have a child with albinism in the first place. We know the following:

- Both parents are unaffected.

- The couple has already had one affected child.

- Albinism follows an autosomal recessive inheritance pattern.

Let ( M = normal gene ) and ( m = mutated gene ). Since the condition is recessive, the affected child can be assumed to have a “mm” genotype. Barring the possibility of a de novo mutation (which are assumed to be rare), the affected child must have inherited one ”m” allele from each parent. Since both of them are unaffected, however, we can assume that they are both carriers (genotype “Mm”). In conclusion, 1/4 of their offspring (25%) <em>for any given pregnancy</em> may be expected to have albinism. See the resulting Punnett square:

<u>       |      M    |      m   </u>

<u>M    |    MM   |    Mm  </u>

<u>m    |    Mm   |    mm  </u>

Note that the question asks about the probability that not one but two consecutive births result in affected children. Since it can be assumed that both events are independent (meaning: the outcome of a pregnancy does not influence the outcome of following ones), we may apply the rule of multiplication for probabilities. The final answer is therefore 1/4 * 1/4 = 1/16.
