The Alpha Centauri system is the closest star system to the sun—The Alpha Centauri system is 4.36 light years away from earth and our sun, which is a very long distance, but still short enough that it is the current third-brightest star/star system visible from Earth.

Which of the following statements best supports the claim that organisms share fundamental processes as a result of evolution? (
Nutka1998 [239]

Answer:

C

Explanation:

All living organisms' cell are composed of genetic material in form of DNA. The DNA encodes the information needed for the production of useful products (proteins). The way in which the information is encoded is called the GENETIC CODE. It consists of all the triplet nucleotides in DNA or RNA that encodes an amino acid.

This genetic code is universal i.e. the same genetic code is employed by virtually all living organisms, as a codon does not encode another amino acid in another organism. It is universal that AUG specifies Methionine in all living organisms. This shows that all organism share a common evolutionary history.

Hence, it is possible for an organism to express a gene from another organism since the same genetic code will be used to read the information in the gene.

Would an animal that was a great sprinter, but was a poor distance runner, have more red muscle or white muscle? Why?
Zielflug [23.3K]
<span>White muscle Let's look at the difference between red and white muscles. Red muscles are red because they have a large concentration of myoglobin in them. This kind of muscle performs work via aerobic metabolism. So they can sustain their activity for a long time without fatigue, but they're slow. White muscles on the other hand, have little myoglobin, but are very rapid in contraction. But most of their work is via anaerobic metabolism and they accumulate lactic acid while performing work. This makes these kind of muscles very fast and powerful for short bursts of work, but they fatigue quickly.</span>
