Sickle cell anemia is known to run in a family. A pedigree chart for this family is shown below. The parents are shown at the to

p and from left to right appear as a half-shaded circle labeled 1 next to a half-shaded square labeled 2. The two are connected by a straight line. Below the parent pair is a vertical straight line connecting to the next row of circles and squares which are the offspring. Starting from left an unshaded square labeled 1, half-shaded circle labeled 2, another half-shaded circle labeled 3, and a completely shaded square are shown labeled 4. All of these are also connected by a horizontal straight line. What best describes offspring 4?

In a pedigree chart, male is represented by a square and female a circle. Different generations in a family are lined up with the oldest at the top.  Shading represents the disease with half shade means a carrier and full shade means having the disease.


Based on the description, offspring 4 is represented by a completely shaded square so he is a male with sickle cell anemia.

Why is conserving energy resources not a simple problem with a simple solution?
anyanavicka [17]

Answer:

Because the uncontrolled and unreasonable use of energy resources in the past few decades has led to the depletion of conventional type of resources. Although, measures are taken at the government levels to control the energy consumption, these attempts only meet with little success. Public awareness is the only way to successfully deal with this problem.

What quantities are related by Ohm's law? Check all that apply. voltage conductivity current resistance insulation
Free_Kalibri [48]

Answer: Current, resistance and voltage are the quantities which are related by Ohm's law.

Explanation:

A law which states that electric current is directly proportional to voltage and inversely proportional to resistance is called Ohm's law.

Mathematically, it is represented as follows.

I = \frac{V}{R}

where,

I = current

V = voltage

R = resistance

This means that the quantities related by Ohm's law include current, voltage and resistance.

Thus, we can conclude that current, resistance and voltage are the quantities which are related by Ohm's law.
