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.
It might be a tortoise because turtles usually have flatter shells I think. Tortoises don't need a water habitat. You could google the characteristics of it to find out for sure though. :)
There's more to remember in college. This is the case for all subjects
The question is incomplete as it does not have the options which are:
A) test cross
B) two-point test-cross
C) three-point test-cross
D) chi-square analysis
E) recombination frequency (r) calculation
Answer:
D) chi-square analysis
Explanation:
Chi-square analysis is a test which is used to study the relationship between the variables of a population. The Chi-square test is performed to test if the observed results are due to chance or is real.
To test this a null hypothesis is formulated which says that there is no relation between the variables. The chi-square test is used in various disciplines but in molecular biology, there are used in the linkage mapping and the Mendelian crosses.
Thus, Option-D is correct.
