A scientist wants to make certain the results of her experiment are accurate. She has repeated the procedure numerous times and

Romashka [77]

The correct answer is D. Have other scientists repeat the procedure and obtain the same results.

Explanation:

One of the most accurate ways to validate the results of an experiment is to allow peers (other scientists) to review the experiment and repeat it, which is known as replication. This process is required to make sure the results are accurate because if the experiment is repeated by a different scientist and the results are different this shows the data is not consistent and therefore the results are invalid. Moreover, inconsistency or lack of replication can occur due to incorrect processes or bias by the scientist.

According to this, the next step in this situation is to "have other scientists repeat the procedure and obtain the same results".On the other hand, repeating the experiment but changing one of the variables or the procedures is not a correct step because this will change the essence of the experiment and lead to different results.

considering periodic trends, valence electrons in which of the following atoms experience the greatest effective nuclear charge

Anni [7]

The effective nuclear charge is the difference between the atomic number an element and the shielding constant. Hence, the atom which experiences the greatest nuclear charge is Sulphur, S.

Calculating the greatest effective nuclear charge, :

$Z_{eff} = Z - S$

Z = Atomic number ; S = shielding constant

For Magnesium, Mg:

Z = 12

S = 10

$Z_{eff} = 12 - 10 = 2$

For Aluminium, Al:

Z = 13

S = 10

$Z_{eff} = 12 - 10 = 3$

For Sulphur, , S:

Z = 16

S = 10

$Z_{eff} = 16 - 10 = 6$

Therefore, the atom whuch experience the greatest $Z_{eff}$ is Sulphur.

A fruit fly population has a gene with two alleles.

hjlf

Answer:

The Hardy Weinberg equation is defined as p squared plus two p Q plus Q Squared equals one, and this equation is used to determine if evolution is occurring in a particular population. So P is defined as the dominant Ulliel frequency and cue is defined as the recess of illegal frequency. So if one of these illegal frequencies is given, we can easily find the frequency value for the other a wheel. So let's say that the dominant frequency, the dominant Ulliel here, is defined as a one. We have another legal called a two, so let's say a one is given. So to find a to all we need to dio so a two frequency would be equal toe one minus a one. And once we have the value of A to we can determine the hetero zegas frequency by solving this part of the equation. So we would just do two times a one times a two, and that would give us the frequency of the hetero Zika's individuals. Okay,

which line from the passage best provides evidence to support the claim that sugar was more of "a killer" in louisiana than in t

Naddik [55]

Answer:

The correct answer is option D "People needed to work faster than the weather. . . ."

Explanation:

The text refers to sugar as "a killer" in Louisiana as they did not have the hot weather as in the Caribbean to harvest.

Then, slaves had to increase their production and beat the weather because otherwise the crop would be completely ruined.

For this reason, the work of slaves in Louisiana was much more exhaustive than in the Caribbean.
