Answer and Explanation
Mendel selected a group of dwarf plants and sel pollinated them by dusting mature pollen grains onto them. He then collected the resulting seeds and planted them and noticed these seeds germinated and grew into dwarf plants only.
He also selected tall plants and self-pollinated them. the resulting seeds he observed that they grew into a micture of tall and dwarf plants. He took the seeds of tall plants only and repeated the experiments for many generations until he obtained only tall plants.
He then crossed cross-pollinated purebreeds tall garden pea with pure breed variety. He planted the seeds and observed the offsprings were all tall plants. He crossed two of these tall offsprinf from the F1 and planted the resulting seeds. the second filial generation consisted of a mixture of tall and dwarf plants.
He counted these plants and noted that the ratio of tall to dwarf was about 3:1. From this, he postulated that there are now laws governing inheritance.The law of independent assortment and law of segregation.
Hydrogen bonds exists between the DNA strand and its complementary strand such that; there are two hydrogen bonds between every A and T, and three between every C and G.
Therefore; in this case there will be (2 ×3 ) +(3×3) = 15 hydrogen bonds for the above strand. this is because Adenine binds to Thyamine with two bonds (3 pairs) and Guanine binds to Cytosine with three bonds (3 pairs).
<span>Sunlight emits light energy which is absorbed by the thylacoids in
the chloroplasts of a plant. Chloroplasts are organelles in a plant
cell whose funtion is photosynthesis (the use of light to make
energy). Thylacoids are a part of the chloroplast which absorbs
light. The thylaciods convert the light into energy molecules NADPH
and ATD. The Calvin cycle then takes place in the stroma
(gellatinous matrix of the chloroplast). The Calvin cycle is the
use of ATP and NADPH plus carbondioxide to produce starch. Starch
is the polysaccharide sugar formed from glucose synthesized in a
linear chain. The starch is the storage of the glucose which is
used as an energy source for the plant cells. </span>
