Answer:
The correct answer is c. cell fractionation
Explanation:
Cell fractionation is the technique which allows different cells part to be separated from each other on the basis of their density gradient by using a centrifuge.
In cell fractionation, first the cell wall and membrane of cells are broken by chemical, physical or mechanical method. Then the cell component can be separated by centrifuging them at different rpm.
Components that have higher density can be found in the bottom and the light density can be found on top of the tube. Therefore the correct answer is c. cell fractionation.

The phase of meiosis is represented to B
Answer:
Chlorophyll, water, ATP, NADPH
Explanation:
Photosynthetic light reaction takes place in the thyllakoid membrane of green plants. The Chloroplast of green plants harbors pigment molecules called Chlorophyll; which has the ability to capture the energy of light. This captured energy is used to generate high energy electrons which reduces NADP+ to NADPH and also produces ATP which are further used to produce sugar(food) in the next stage of photosynthetis called Calvin cycle.
Answer:
The brown-eyed parents must be HETEROZYGOUS to produce a blue-eyed child
Explanation:
This question involves a single gene coding for eye color in humans. The allele for brown eyes (B) are dominant over the allele for blue eyes (b). This means that an individual that is heterozygous (Bb) will phenotypically have a brown eyes.
According to this question, a blue-eyed child (bb) will be produced when two brown-eyed parents are HETEROZYGOUS (Bb) for the eye color trait. This means that each of the parent donated the recessive allele (b) to produce the (bb) offspring. Please find the punnet square attached.
