Answer:
- Independent variable: Car weight (car + block with a mass of 10 grams)
- Dependent variable: Speed (the time the car takes to descend the ramp)
Explanation:
As you can see in the question above, Shawn wants to check the speed that a car takes when going down a ramp, related to the weight of this case, that is, he wants to know the influence of the weight that the car presents, in its speed in going down a ramp.
In this type of experiment, we can consider the weight that the car presents as the independent variable. This is because independent variables are those that influence a result within the experiment. They happen without the influence of another variable and are factors that impose changes in the analyzed system.
The dependent variable, however, is the car's speed down the ramp. This is because the dependent variables are those that need and are influenced by the independent variable, to achieve a result that can be measured and analyzed.

Answer:
When a phenotype produced by certain alleles helps organisms survive and reproduce better than their peers, natural selection can increase the frequency of the helpful alleles from one generation to the next – that is, it can cause microevolution.
Explanation:
Based on the information, you can determine that color-blindness is X LINK RECESSIVE.
C) X-linked recessive.
<u>Explanation:</u>
Color blindness is the common hereditary condition that is hereditary passed from their parents. The gene for the color blindness found in the chromosomes. So for the male to be color blind. X linked color blindness is the recessive traits.
Female heterozygous of the trait have a normal vision. The X link recessive is the mode of the inheritance in which the mutation of the gene on the chromosomes causes the depletion in the phenotype because the male has one Y and one x chromosomes.
