2n because when 2 gametes of n amount of DNA fertilise together they make an organism that is similar to its parents and have the total amount of DNA as 2n, just like parents.
Answer:
6 thymine, 4 guanine. 4 cytosine
Explanation:
Adenine pairs with thymine, so you need 6 of each
Cytosine matches with guanine, but the total of nucleotides is 20, so
6(adenine)+6(thymine)=12
20-12=8
8= 4(guanine)+4(cytosine)
It is important that it has half because there is a half that comes from each parent. so to equal it all out human gametes have a half set of dna instead of a full set
Answer:
Due to newly formed land.
Explanation:
Surtsey provided ideal conditions for studying primary succession because due to volcanic eruption all the vegetation and living organisms are destroyed from the surface and the land has no vegetation. Primary succession only occurs when the land is colonized for the first time after the formation of land due to natural disaster such as volcanic eruption etc. So we can say that Surtsey provided the conditions for observing primary succession.
About 90% of our DNA is the same.
