Explanation:
Kepler-452b
Kepler-452b (a planet sometimes quoted to be an Earth 2.0 or Earth's Cousin based on its characteristics; also known by its Kepler Object of Interest designation KOI-7016.01) is an exoplanet orbiting the Sun-like star Kepler-452 about 1,402 light-years (430 pc) from Earth in the constellation Cygnus
Hello!
prothrombin is a protein presented in blood plasma which is converted into active thrombin during coagulation
fibrinogen is a protein that helps with blood clotting
prothrombin turns into thrombin through extrinsic and intrinsic pathways which activates fibrinogen

Chromatids are only called as chromatids when they are sister chromatids, meaning that when chromosome have two double stranded DNA attached together, each of the double stranded DNA is a sister chromatid, and while the whole thing (the two sister chromatids that are attached together) is called a chromosome.
So after the DNA has been replicated, the chromosome consist of 2 sister chromatids, attached to each other at their centromere.
Overall, sister chromatid is one of the two double stranded DNA in a replicated chromosome, and chromosome is the whole "X" shape that we see. For example, in humans, after the S phase of interphase in the cell cycle, we have 46 chromosomes, with 92 chromatids, since each chromosome is an "X" shape, by having two sister chromatids.
Hope this helps!
The correct answer is option D, that is, whole blood with an anticoagulant added.
The PCV or the packed cell volume determines the proportion of red blood cells present in the whole blood. It is one of the various tests, which may be used to diagnose or monitor a condition known as anemia. The test may also be used to diagnose or monitor a rare kind of blood cancer called polycythemia.
The PCV can be determined by centrifuging heparinized blood in a capillary tube at 10000 RPM for 5 minutes. This distinguishes the blood into layers. The volume of the packed RBCs divided by the total volume of the blood sample provides the PCV.
