Answer:

The presence of fins in both species represents an adaptation to the same environment (i.e., sea), but in no way does this adaptation means close evolutionary homology between fishes and mammal cetaceans (whales)

Answer:

Homologous structures

Explanation:

Homologous structures are parts of the skeleton of organisms are similar in structure. This gives the impression that their is a common  ancestor. Mostly the structures are not similar and the function may or may not be the same in appearance per-say such as fish fins and whale flippers.  The important part of homologous structures is that they have a skeletal similarity.

This, and the emergence of other structures is the product of evolution so each organism can have the best chance of adaptation to their environment. This ensures the survival of a species and the continuation of the next generation.

If a purple-flowered, heterozygous plant were crossed with a white-flowered plant, what is the expected ratio of genotypes among
astraxan [27]

suppose P is a dominant allele for a flower color and p is a recessive one.

The expected ratio of genotypes among the F1 offspring is 1 Pp : 1 pp.

The white pea bloom was "masked" in the F1 generation, which caused all of the flowers to be purple.

The "masked" genes from the F1 generation were permitted to mate, but they were only allowed to pair once, leaving the other three times to appear with purple flowers, resulting in a 3:1 ratio of purple to white blooms in generation F2.

He paired a homozygous dominant flower with a homozygous recessive flower in his initial attempt. As a result, all of the F1 generation's progeny were heterozygous, making them all purple.

Two heterozygous, one homozygous recessive, one homozygous dominant, and the progeny of the F1 generation were crossed with another heterozygous plant.

What are the consequences of having pyrimidine dimers in dna?
Sophie [7]

Answer:

Mutations on DNA that can lead to skin cancer and other skin problems

Explanation:

A Pyrimidine dimer is a molecular lesion that causes mutations that can lead to melanomas and skin sensitivity. It is caused by a photochemical reaction after the exposition of DNA to ultraviolet light.

These mutations happen on thymines or cytosines and can be repaired by a photolyase, an enzyme that adhere the dimers.

I hope you find this information useful and interesting! Good luck!
