Grey rabbits are made to inhabit warm places during the spring. They hibernate during the winter. They make use of warm weather to reproduce.
Answer: Proteins
Explanation: Proteins are produced in a process by which the genetic information in an mRNA sequence is converted into a polypeptide chain. The first step in the process of protein synthesis is transcription. Transcription is a process by which the genetic message encoded in a DNA is copied into an mRNA. Transcription takes place in the nucleus. After transcription, the mRNA leaves the nucleus and enters the ribosome where translation takes. In the ribosome, the mRNA sequence is used to make a protein. The genetic information encoded in the mRNA strand is converted into a polypeptide chain. The newly synthesized polypeptide chain undergoes posttranslational modifications to become a biologically functional protein.
Answer: D) By decreasing the activation energy of a reaction
A catalyst is a substance that speed up the rate of chemical reaction without affecting the product of the reaction. They only affect the rate of reaction not the yield of reaction.
Catalyst provide an alternative reaction pathway that has lower activation energy than that of uncatalysed reaction. It increases the frequency of collision and because of these greater collision which lowers the activation energy of the reaction.
The answer is A because the subject is responding to something that is going on outside of it, if that makes any sense :)
Hope this helps! Have a great day!
