Write a scientific argument that addresses the question: Why is Jackie an elite distance runner when no one else

Chemistry

Travka [436]3 years ago

Answer:

A mutation in Jackie's genes culminated in developing a new enzyme, resulting in the long-distance running phenotype. Jackie appears to have either the A1Am or A2Am gene variants. Jackie used to play for long periods without tiring, suggesting that her gene variants could generate a protein that results in a stamina feature. Jackie's father bears the A1A2 gene. Since Jackie's mother is a good sprinter, I suspect she bears A1A1 gene variants. Sprinters have much ACTN3 protein in their cells, so that she may have two copies of the A1 gene variant. This means Jackie has at least one clone of the A1 gene allele. People with one or two versions of the A1 gene variant, on the other hand, are rarely successful long-distance runners. Out of 100 total distance runners, only 28 (25 and 3) have an A1 gene copy. Since the gene variants she may have inherited from her parents cannot justify her stamina, she may have a mutant gene version that contains a long-distance running protein. However, I do not believe she has AmAm gene versions because mutations are uncommon. Jackie is an elite long-distance runner due to a gene that no one else in her family has.

Anni [7]

Answer:

Explanation:

The first ionization energy varies in a predictable way across the periodic table. The ionization energy decreases from top to bottom in groups, and increases from left to right across a period. Thus, helium has the largest first ionization energy, while francium has one of the lowest.

If you start with 6 mol of nitrogen gas (N2+) what mass (g) of ammonia (NH4) will be produced?
Yanka [14]

Answer:

204g of NH3

Explanation:

The balanced equation for the reaction is given below:

N2 + 3H2 —> 2NH3

Next, we shall determine the number of mole NH3 produced by reacting 6moles of N2. This is illustrated below:

From the balanced equation above,

1 mole of N2 reacted to produce 2 moles of NH3.

Therefore, 6 moles of N2 will react to produce = 6 x 2 = 12 moles of NH3.

Finally, we shall convert 12 moles of NH3 to grams. This is illustrated below:

Number of mole of NH3 = 12 moles.

Molar mass of NH3 = 14 + (3x1) = 17g/mol

Mass of NH3 =..?

Mass = mole x molar mass

Mass of NH3 = 12 x 17

Mass of NH3 = 204g.

Therefore, 204g of NH3 will be produced from the reaction.

taurus [48]

Answer:

No, there is no evidence that the manufacturer has a problem with underfilled or overfilled bottles, due that according our results we cannot reject the null hypothesis.

Explanation:

according to this exercise we have the following:

σ^2 =< 0.01 (null hypothesis)

σ^2 > 0.01 (alternative hypothesis)

To solve we can use the chi-square statistical test. To reject or not the hypothesis, we have that the rejection region X^2 > 30.14

Thus:

X^2 = ((n-1) * s^2)/σ^2 = ((20-1)*0.0153)/0.01 = 29.1

Since 29.1 < 30.14, we cannot reject the null hypothesis.
