How many trips has Earth made around the Sun in 8 mar years
alex41 [277]

The answer is;  15 years

It takes 687 days for mars to orbit the sun once. 8 mars years would, therefore, mean;

8 * 687 = 5496 days

The earth takes 365 days to orbit the sun  once. Therefore, the earth will orbit the following number of times in 8 Mar years;

5496/365 = 15.058

Which is approximately 15 years

Answer:

3rd generation = 2 Hybrid DNA molecules + 6 Light DNA

In Percentage 2÷8 × 100 = 25%

25% of the DNA are hybrid

Explanation:

Semi conservative model proposed by Watson and Crick states that one strand of the DNA comes from parent DNA which act as a template for the other newly formed strand.

First generation:

If cells containing 15 N DNA are transferred to a medium with only 14 N then in initial first generation two parent strands becomes separated and act as template for newly synthesized strands. this means that in first generation both DNA molecules are hybrid, one strand of 15 N DNA and other strand of 14 N DNA

Ist generation = 2 Hybrid DNA molecules

Second generation:

In Second generation these two hybrid molecules become unzip. Two strands are 15N and two strands are 14N. All these 4 strands act as template and 4 new strands are synthesized. The molecules of Hybrid DNA is still 2 with 2 molecules of Light DNA.

2nd generation = 2 Hybrid DNA molecules + 2 Light DNA

Third generation:

In Third generation these two hybrid molecules and two light DNA molecules become unzip. Two strands are of 15N and six strands are of 14N. All these 8 strands act as template and 8 new strands are synthesized. The molecules of Hybrid DNA is still 2 with 6 molecules of Light DNA.

3rd generation = 2 Hybrid DNA molecules + 6 Light DNA

In Percentage 2÷8 × 100 = 25%

25% of the DNA are hybrid
