Answer:
Gases in the atmosphere, such as carbon dioxide, trap heat similar to the glass roof of a greenhouse. These heat-trapping gases are called greenhouse gases
Explanation:
Answer:
The correct answer is b. all tall
Explanation:
If the genotype of one parent for height is Tt and another parent is TT then after the fusion of gamete all the offspring will show tall phenotype because all the offspring will have at least one allele of tall character.
T t
T TT Tt
T TT Tt
So after cross two phenotype would be homozygous dominant for tall character and the other two will be heterozygous dominant for tall character. Therefore all the offspring would be tall.
Tymine (t) can only pair with (a) in a dna strand. And the other letters which are G and C can only pair with each other. So A can be with T, T can be with A..... G can be with C and C can be with G.
the letters stand for:
A: adenine
G: guanine
C: cytosine
