Based on the weather map above, which statement is true based on the weather map?
alisha [4.7K]

Answer:

A warm front is moving towards South Carolina bringing rainy conditions

Explanation:

From this weather map, we can see that South Carolina will soon be under the influence of a warm front. The warm front is moving towards this state, and it is coming from southeastern direction, thus it has been formed over warm waters. Because it has been formed over warm waters, this front is warm and very moist which will result in lot of rainfall once it comes upon a natural barrier to cause condensation, and the Appalachian Mountains will do just that, thus South Carolina will receive a lot of rainfall.

Which biological scenario(s) best describes phenotypic plasticity for a trait?
DIA [1.3K]

Answer:

C) II and III only

Explanation:

Option 1 is not an example of phenotypic plasticity because each person is born with their own blood type and this doesn't change based on their environment and behavior.

Option 2 is an example of phenotypic plasticity because a person's red blood cell counts can increase based on their environment, i.e. moving to Denver, CO from Death Valley, CA. The higher elevation and decreased oxygen causes your body to produce more red blood cells.

Option 3 is an example of phenotypic plasticity because one twin can be taller than another because of differing behaviors, environments, etc.

You are required to make 10mL of a 0.5M solution of HCl. Your stock solution of HCl is 90M. Using distilled water (dH2O) as a so
sleet_krkn [62]

Answer:

0.0556 mL of 90 M HCl would be taken and 9.944 mL distilled water added to make 0.5 M, 10 mL HCl solution.

Explanation:

From the dilution equation:

<em>Initial molarity (m1) x initial volume (v1) = final molarity (m2) x final volume (v2).</em>

In this case, m1 = 90 M, v1 = ?, m2 = 0.5 M, and v2 = 10 mL

v1 = m2 x v2/ m1 = 0.5 x 0.01/90 = 0.0000556 L

v1 = 0.0556 mL

This means that the initial volume of 90 M HCl to be taken is 0.0556 mL. Since the final volume to be prepared is 10 mL,

 10 - 0.0556 = 9.944 mL

<em>Hence, 0.0556 mL of 90 M HCl would be taken and 9.944 mL distilled water added to make 0.5 M, 10 mL HCl solution.</em>
