Answer:
a) The genes present on separate chromosomes exhibit indepedent assortment.
b) The genotype of tall and purple flower parent= TTPp
The genotype of short and purple flower parent: ttPp
Explanation:
a) In a dihybrid cross, if the genes are present on the same chromosome, they will not exhibit independent assortment. The genes present on the same chromosome are called linked genes. Linked genes are inherited together. The absence of independent assortment of a linked gene gives more of parental types in F2 progeny. Therefore, if genes are not present on a separate chromosome, Mendel’s ratios deviate.
b) Alleles for tallness and purple flower are dominant. In the progeny, all the plants are tall. This means that the dominant tall plant is homozygous. With respect to flower color, the trait exhibits segregation of dominant and recessive alleles and both purple and white flower progeny are obtained. This makes both the plants heterozygous for the flower color gene.
The genotype of tall and purple flower parent= TTPp
The genotype of short and purple flower parent: ttPp
The answer is D. learned behavior.
A change in behavior of an organism takes place due an experience is called learning. Animals learn behavior in many ways. On such way is given the question that anole lizard ate bright red butterfly instead small insects which are its normal food and became ill. Anole lizard learned through experience that bright red insects are not its food. Thus, a learned behavior is one that an organism develops by encountering experience.

Explanation:
Ponds and lakes are both inland bodies of freshwater that contain living creatures. Lakes are normally much deeper than ponds and have a larger surface area. ... All the water in a pond is in the photic zone, meaning ponds are shallow enough to allow sunlight to reach the bottom.
The yearly process known as thermal stratification. A pond that is thermally stratified simply means that there is a noticeable temperature gradient as the water gets deeper. You may have noticed this in summer while swimming.
