Fill in the blank Competition drives natural selection as individual members of a species compete with each other for limited na
maks197457 [2]

Answer:

1. Intraspecific

2. speciation

3. fossil record

4. The fossil record provides empirical evidence for evolution because it shows that species now aren't the same as species that existed in the past and that small changes happen over time to create new species.

5. A geographic variation in the fossil record occurs when two similar organisms occupy the same time span in two different places. These organisms hold the same purpose within the overall ecology.

6. A more detailed fossil record is preferable for supporting evolution because it allows for the instances of gradual change to be recorded and placed into broader speciation events.

7. Fossils provide a great many intermediaries that connect past species with their living descendants.

8. Intraspecific competition is competition that occurs within species. This is the competition that drives natural selection.

2.2.2 Quiz: Transcription
Karolina [17]

<u>Answer</u>:

Actions happens after transcription ends is "An mRNA molecule leaves the nucleus of the cell."

<u>Explanation</u>:

Transcription is the process of formation of mRNA from DNA. DNA is the genetic material which carries all the information for the formation of mRNA and then protein. Transcription occurs in nucleus, but as soon as the mRNA is formed it unwinds from the template DNA stand and moves into the cytoplasm for the next process i.e. translation. Translation occurs nearer to the ribosomes, it is the formation of protein from mRNA strand. combinedly transcription and translation are referred as the central dogma of the molecular biology.
