Answer:
option D is incorrect
Explanation:
the sedimentation coefficient is measured in Svedberg units named after the scientist Theodore Svedberg. the shape of the particle being measured in the ultracentrifuge is one of the factors that determines the sedimentation coefficient. the values are usually not additive as the sedimentation coefficient is based on the rate at which a particle sediments in an ultracentrifuge and not on the size. for example, the sedimentation coefficient of eukaryotic ribosome is 80S but is made up of the 60S large subunit and the 40S small subunit.
If ecology is an option than it is that.
If the doctor recommends dialysis
for someone who has kidney disease and he goes for a home-treatment option, he most
likely chose hemodialysis. Home hemodialysis (HHD) is the option that offers
freedom to be treated outside of the dialysis center.
A and C are balanced while B is unbalanced.
Answer:
The Ames test, named for its designer, Bruce Ames, is a technique to test synthetic compounds for their disease causing properties. Three analyzer strains are utilized for this reason - Escherichia coli , Salmonella typhimurium strain An and strain B. E. coli distinguishes base pair substitution change though Salmonella typhimurium strain B identifies frameshift transformation and strain A recognizes base pair substitution change. Acridine orange intercalates itself between adjoining bases and contorts DNA helix, subsequently causes additions and erasures during replication process. Along these lines it is utilized to decide frameshift change and this is the reason it seems mutagenic in Salmonella strain B yet not strain A. Sodium nitrite deaminates cytosine to deliver uracil and uracil thus matches with adenine shaping a CG to TA progress. Along these lines it is utilized to decide base pair substitution and that is the reason it seems mutagenic in Salmonella strain A yet not recolor B.
