Answer:
The correct answer is B transcription factors.
Explanation:
Transcription factor are specific regulatory protein also known as sequence specific DNA binding proteins which regulates the process of transcription in eukaryotic cell.
Transcription factors may either turn on or off the expression of a particular gene to ensure that they are expressed in right cell along with perfect amount and manner.
Transcription factor such as helix turn helix ,leucine zipper, zinc finger play an important role in regulating the activity of many proteins such as DNA ploymerase, helicase
Answer:
To find the fossil evidence to fill the largest remaining gap in whale evolution, you would search age sediment of 37MYA-46MYA.
Explanation:
Fossils are the dead remains of living organisms. The gaps between the fossils usually point out the uncertainties in the understanding of precisely how species are evolved. However, the gaps do not indicate the weakness in the theory of evolution itself. There are many gaps in the fossil records that continue to shrink with time as new fossils are discovered. The gaps are contingent features of fossil records.
Secondly, to discover the fossil evidence to fill the largest remaining gap in the evolution of whale, you would search the age sediment of 37MYA-46MYA.
C) Tundra without a doubt, the tundra biome is very cold year-round and, in some cases especially in Antarctica, can has no visual of the sun for months at a time.
