Although there is no real knowledge or understanding of whether there is other life apart from on Earth. It is strongly believe that out there , there are plenty more things we don’t know about , plenty more living things that we haven’t discovered yet. Scientists are trying to discover these things , if they do exist.

What would happen to the possible variation in gametes if the number if chromosome pairs increased from two to three?
Orlov [11]
<span>If each of the pairs of chromosomes was heterozygous (what gives you the highest potential number of different gametes), then the number of possible gametes increases from 4 to 8 for a diploid organism. To figure out how many are possible, raise the number of homologous chromsomes (2 for a diploid organism) to the power of the number of chromosomes. So if you have two different chromosomes (A and B), raise 2 to the 2nd power (or multiply 2 x 2) and you have 4. If you have chromosomes A, B, and C, then you have 2^3, or 2 x 2 x 2 = 8.

To show possible combinations, AaBb gives you AB, Ab, aB, or ab. AaBbCc gives possible gametes of ABC, ABc, AbC, Abc, aBC, aBc, abC, and abc. </span>

What evidence suggests that RNA appeared before DNA? ribozymes, catalytic RNA, play pivotal roles in modern cells ribosomes are
mote1985 [20]

Answer:

<em>The evidence that suggests  RNA  appeared before DNA is the fact that RNA can act as an enzyme to self-edit their own genetic code. </em>Moreover, it has the ability to store genetic information, while transfer and ribosomal RNA have the ability to translate genetic information into proteins.

Explanation:

RNA has a great capability as a genetic molecule, it once had to carry on hereditary process on its own. It is absolutely sure that RNA was the first molecule of heredity. However, a single stranded RNA is rather unstable and easily damaged by enzymes. By essentially multiplying the existing RNA molecule, and using deoxyribose sugar instead of ribose.

<em>The DNA evolved as a much more stable form to pass genetic information with accuracy.  It shows a biological evolutionary purpose .</em>
