Answer:
D.The light-dependent reactions absorb sunlight and transfer the energy to electrons.
Explanation:
Firstly, the organelle that was described as small green organelle inside a cell as noticed by Quinlin is the CHLOROPLAST. Chloroplast is an organelle present in the cells of green plants, in fact, it makes plants green. Chloroplast is the organelle where the unique process of PHOTOSYNTHESIS occurs in plant cells.
However, the photosynthetic process is divided into stages namely: light-dependent and light-independent stages. The light dependent stage, which involves the production of ATP (energy carrier) and NADPH (electron carrier), must PRECEDE the light independent stage or Calvin cycle. Chloroplast contains a pigment called CHLOROPHYLL, which absorbs light energy from the SUN in order to power the light dependent stage of photosynthesis.
Hence, the light-dependent reactions, which absorb sunlight and transfer the energy to electrons must occur first in the organelle.
It can move towards the sunlight.
1.It is not natural.
2.It can came up with side effects and unbalance some species.
Answer:
The recombination frequency between two genes can not be more than 50 percent due to the independent and random assorting of the genes that are linked generating 50% recombination.
* Genes should be located far enough from one another so that crossover points can be made.
Example: Genes present at the 2 extreme ends of the chromosome.
* There should not be the linkage between the two genes due to linked genes go together. So no recombination happens.
It may be more than 50% if selected parents are heterozygous. But Mendel took homozygous parents. So, the maximum is 50%. There will be no recombinant if the two genes are linked.
