In the African savanna, more wildebeests are born than the environment can support. Which is most likely to happen over a period
Maurinko [17]

Answer:

Eventually, the environment will be unable to support the production of wildebeests, this will cause there to be a loss of vegitation that then causes a food shortage, and then the wildebeests will starve.  

Explanation:

It's a very unhappy process, but those herds who don't migrate to another pasture will starve and die. The death will depopulate the savanna and give the fields some time for regrowth and the cycle will begin again.

Hope this helps! :)

Arrange the events taking place during transcription in order: i) The pre-RNA undergoes processing ii) RNA polymerase moves down
Anastasy [175]

Answer:

RNA polymerase binds to the promoter

Polymerase initiates RNA synthesis at the start point on the template strand

RNA polymerase moves downstream unwinding the DNA

RNA transcript is released and polymerase detaches from the DNA

The pre-RNA undergoes processing

Explanation:

The promoter is the specific DNA sequence that serves as a binding site for RNA polymerase. The enzyme RNA polymerase recognizes the promoter sequence and binds to it to begin the process of RNA synthesis. The process of RNA synthesis begins at the start site where the process of the unwinding of DNA duplex is initiated.

The unwinding separates the two DNA strands at the start site where RNA polymerase begins the process of synthesis of the new RNA strand. The newly formed RNA strand and RNA polymerase are released from the template strand after the termination of the process.

In eukaryotes, the primary RNA transcript undergoes the process of splicing of introns, the addition of poly-A tails and 5' cap which in turn transform it into the mature mRNA.

Which has more genetic information, a body cell or a gamete? Explain your answer
Natasha_Volkova [10]

The body cell has more genetic information. A gamete only has half the information of a body cell. So when two gametes combine (a sperm and an egg), together they provide the child with all the genetic information needed for its body cells.

Hope this helps :)
