Your answer is (B.)
Fossils in newer layers if rock are generally estimated to be younger than fossils found in the deeper layers because it is closest to the surface. The soil and earth didn't have enough time to "bury" the remains of the dead animal ( Bury is used for a simpler term) underground. The farther down a fossil is the more likely it is older unless the animal tends to burrow. Seeing as the question is probably talking of older animals that is unlikely for an animal to burrow that far. So your answer is B.
Pros (good):
- Inexpensive
- Can degrade the crudest oils
- Quick and minor waste is water and CO2
Cons (bad)
- Waves can carry bacteria into place they are not needed or wanted
- Germs may harm marie animals by putting excess CO2 in water
- Germs may be harder to exterminate because they are engineered
1. An underdeveloped DNA molecule would result in mutations. On the genetic level, this could mean entire traits are deleted or that an early stop occurs in transcription, which could cut off parts of instructions.
2. Genetic code is the nucleotide sequence of a gene while the gene expression is how these sequences are used to make functioning amino acids and proteins to create DNA.
3. In each cell itself there are roughly 42 million proteins.
Answer:
Evolution is the <u>biological process</u> that happens over time in a population, giving rise to new <u>species.</u> The theory of evolution states that all organisms alive on Earth today <u>have a common ancestor</u> which lived <u>years ago</u>.
Explanation:
Evolution is one of the fundamental reason of diverse life on Earth today. Principally, this process takes place by changes in genetic elements via mutations and crossing-over. The positive changes (mutations) allow the organism to develop better condition in order to survive in changing environmment. However, if the changes takes place at major scale, it also leads to the creation/development of new species. To explain this further, I have added a photograph where we can see how different organisms were evolved in the history of Earth.
