Answer:
Elongated shape
Explanation:
Centrifugation separates molecules on the basis of angular motion.
Due to spherical shape, the value of 'f' is lesser for a spherical protien than the rod shaped one.
Hence the sedimentation coefficient for an elongated protien is 2.6S while htat of a spherical protien is 4.31S.
Hence its elongated shape results in slow centrifugation.
Some of the important principles of centrifugation are as follows :
- The greater the mass, the more is the sedimentation rate i-e the one with greater mass will move down more rapidly as compared to the one with les mass.
- Shape of particles also effect it, the rounder the particle, the lower frictional coeeficient.
- Density of particles
- Density of fluid
Answer:
A) areolar tissue soaks up excess fluid in an inflamed area
Explanation:
Areolar tissue is found around blood vessels, muscles, nerve bundles. Edema which is also a part of inflammation occurs when blood capillaries of blood vessels leak the fluid and is soaked by areolar tissue. So excess fluid in these tissue cause swelling of that part.
Edema is one type of defense reaction to the cell injury. With fluid white blood cells and defense proteins move in the area and counter the infectious agent of injury and helps in eliminating the injurious factor. So the correct answer is A.
