Answer:
D
Explanation:
This is the more likely explanation, as there must be a limit to leg length in an animal that has to run very fast and strain their muscles and bones to the limit to do so.
As for the other options, there is no evidence to conclude that the genes that are involved in cheetahs leg length do not undergo mutation because the population exhibits a variety of leg lengths. Neither can we conclude that there are any isolated subgroups in the pupulation. Natural selection does act upon the traits involved in predation, as the question starts by saying that the faster a cheetah can run the more likely it is to capture its prey.
The correct answer is "C."
mRNA stands for messenger Ribonucleic acid. The role of mRNA is to carry genetic information for the synthesis of protein from the nucleus after transcription.
After the transcription process is over, the mRNA leaves the nucleus and heads to the ribosomes in the cytoplasm where translation of this information takes place.
The ribosomes are the work bench of the cell. They receive the mRNA with its coded information, read it and translate it and with the help of tRNA (transfer RNA), amino acids are fetched from the cytoplasm and linked together to form the exact protein that was coded for on the mRNA.
The answer would be RNA and protein. Each subunit is composed of at least one or more rRNA molecules and proteins.
Answer:
All living cells release energy from food molecules through cellular respiration and/or fermentation. Some cells make food molecules using light energy through the process of photosynthesis.
Two ways to cells get energy: cellular respiration and fermentation.
Fermentation: Fermentation, chemical process by which molecules such as glucose are broken down anaerobically.
Cellular respiration: Cellular respiration is the process through which cells convert sugars into energy. To create ATP and other forms of energy to power cellular reactions, cells require fuel and an electron acceptor which drives the chemical process of turning energy into a useable form.
