I believe the punnet square is showing the genotypes of the F2 generation. If that is true, the answer would be 3 red : 1 white. This is because the four genotypes are RR, Rr, Rr, and rr. Out of those, 3 contain the dominant allele R that codes for red, while only one contains both recessive alleles that code for white. Hope this helps!
The surface's albedo of the incident light as a percent is determined as 30%.
<h3>
What is surface's albedo?</h3>
The surface albedo quantifies the fraction of the sunlight reflected by the surface of the Earth.
The surface's albedo of the body is calculated as follows;
surface albedo = intensity of light reemitted / total intensity of light on the surface
<h3>As fraction</h3>
surface albedo = 3/10 = 0.3
<h3>As percentage</h3>
surface albedo = 0.3 x 100% = 30%
Thus, the surface's albedo of the incident light as a percent is determined as 30%.

The angle bisector theorem is commonly used when the angle bisectors and side lengths are known. It can be used in a calculation or in a proof. An immediate consequence of the theorem is that the angle bisector of the vertex angle of an isosceles triangle will also bisect the opposite side.
Answer:Some body systems work together to complete a job. For example, the respiratory and circulatory systems work together to provide the body with oxygen and to rid the body of carbon dioxide. The lungs provide a place where oxygen can reach the blood and carbon dioxide can be removed from it.
