Answer:
Application Dose limits
********************************************************************************************
Effective dose (whole body), Hp (10) 50 mSv per year (or 1mSv per week)
20 mSv per year (or 0.4 mSv per week) averaged over
defined periods of five years
Annual equivalent dose to lens of the eye, Hp (3) 150 mSv
Annual equivalent dose to the skin, Hp (0.07) 500 mSv
Annual equivalent dose to hands and feet 500 mSv
Explanation:
Answer : The correct answer is -
D.Protista and Eubacteria.
Autotrophs are the organisms that can synthesise their own food using substances available in their surroundings with the help of either chemical energy (chemosynthesis) or light energy (photosynthesis).
Heterotrophs on the other hand, can not synthesise their own food and depend on either plants or animals.
Out of the given options, Protista and Eubacteria conatin autotrophs or heterotrophs.
Example- Protozoa (animal-like protists) are heterotrophs that ingest or absorb their food and helps.
Algae, which is a protist and obtains nutrition through photosythesis.
Slime moulds, which are fungus-like protists and are heterotrophic.
Cyanobacteria (also called blue green alage) is a photosynthetic bacteria (belongs to Eubacteria).
Answer: Small molecules can cross plasma membrane into cells
Explanation:
by simple diffusion as they can be soluble in the hydrophobic region of phospholipid bilayer. Lipophilicity is one of the main parameters that determine cell uptake of small molecules
