Answer:
A. 50%
Explanation:
Using Gregor Mendel's genetics cross, the probability of obtaining brown hair is 50% or 2/4. In Gregor Mendel's genetics cross, the dominant gene represented as Bb is crossed against the recessive, bb. On completing the cross, the products of the cross are two dorminant gene (brown hair) with a trait of red hair and the recessive gene will not be expressed, while the two remaining products are recessive, bb and therefore the recessive gene for red hair will be expressed.
According to Mendel's experiment if we construct a punnet square the expected ratios should be 9:3:3:1. From our experimental results,
purple smooth = 75 ( 0.56) the expected is 0.56
white smooth = 28 ( 0.21) expected is 0.19
purple wrinkled= 24 (0.18) expected is 0.19
white wrinkled = 8 (0.06) expected is 0.06
From this results we plug the observable and expected values in a chi-square which is used to account for the differences between the expected and observable values. Then we conclude that the deviation of the observable value from the expected value is probably due to random sampling error and therefore we accept the hypothesis, such that the results are in consistent with the law of assortment.

Answer:
Absorbs co2 if I am correct
Explanation:
Both lipids and carbohydrates are important in animal cells because store energy. The main biological functions of lipids include storing energy, signaling, and acting as structural components of cell membranes. Carbohydrates on the other hand have six major functions in the body; including providing energy and regulation of blood glucose, sparing the use of proteins for energy, breakdown of fatty acids and preventing ketosis.
