Answer:
(b) Digestive tract and liver
Explanation:
The digestive system consists of the digestive tract and liver. The digestive tract is made up of a large number of parts. These parts include the esophagus, stomach, intestines, rectum, etc. Food enters the mouth and travels down the digestive tract and out passing the rectum. The liver is where the blood passes through and it is responsible for many functions such as the metabolizing of fats and proteins, separating and storing vitamins and minerals, regulating different chemicals found in the blood, etc.

Answer:
Natural selection is the process through which populations of living organisms adapt and change. Individuals in a population are naturally variable, meaning that they are all different in some ways. This variation means that some individuals have traits better suited to the environment than others.
Answer:
The ear length will be 11 cm.
Explanation:
To know about the ear length of F1 generation, we need to know that how much length in centimeters is contributed by each of the alleles. As we know, each allele has the same value for contributing to the effect of ear length, hence we can divide the ear length by 4 to get our results.
As 6 divided by 4 is 1.5 hence, the allele a and b contribute to 1.5 cm of the length of the ear.
6 divided by 4 is 4, hence the alleles And B contribute to 4 cm of the length of the ear.
The F1 generation will have AaBb genotype hence, the lenght will be 4+1.5+4+1.5 = 11 cm.
