The whale's flipper and tail flukes and fish fins are analogous structure as they have different structural formation but they perform the same function.
Flipper and tails are locomotory organs in the whale and helps the whale in propelling similarly fins in the fish assist the fish in swimming. Both the strcutures have evolved differently and are made of different materials.
The answer is 4 chemical energy from the grass.
HAPPY NEW YEAR!
Answer:
Genetic Mutation
Explanation:
Speciation can be driven by evolution, which is a process that results in the accumulation of many small genetic changes called mutations in a population over a long period of time.
There are a number of different mechanisms that may drive speciation.
Two of them to point out here.
1. natural selection
2. genetic drift
genetic drift describes random fluctuations in allele frequencies in populations, which can eventually cause a population of organisms to be genetically distinct from its original population and result in the formation of a new species.
Answer:
Hello! There are numerous things that support Darwin's theory of evolution, but the most credible ones include:
*Homologous structures - structures that are similar in structure but different in function (e.g. wing of a bat and arm of a human).
*Embryology - the study of embryos
*Continental drift - some fossils of organisms that were adapted to a different environment are often found in different climates/areas they don't seem to have been adapted to.
*DNA - similarities in the genomes of certain animals are often used to compare amino acid sequences and protein production.
I hope I helped!
There are a bunch more, but I decided to leave a select few for you to write about.

Mitochondria are a<span>n organelle found in large numbers in most cells, in which the biochemical processes of respiration and energy production occur. It has a double membrane, the inner layer being folded inward to form layers (cristae).</span>
