<span>Negatively charged R-groups in the primary structure.
This is because nickel acts as a cation, therefore you would be attracting anions, in this case it would be on the proteins that would be binding to the column. Once they bind to the matrix a was buffer of high salts can elute the proteins.</span>
Answer:
The correct answer would be group D- 809 kg.
It can be explained with the help of pyramid of biomass.
Pyramid of biomass represents biomass or the amount of organic or living matter present at each trophic level in an ecosystem.
The amount of organic matter is usually expressed in grams per meter square (g/m²).
There are usually four trophic levels in the pyramid of biomass: primary producers, primary consumers, secondary consumers, and tertiary consumers.
Usually, the biomass decreases as we go up the trophical levels specially in terrestrial ecosystem. Inverted pyramid can be observed in case of aquatic ecosystem (biomass of phytoplanktons is less than that of herbivores).
Here, maximum biomass (809 kg) belongs to the group D and hence, it would belong to primary producers.
Answer:
Plant cell
Explanation:
Cell wall: cell wall is only found in plant cell . it is made up of cellulose. it's function is to give shape to the cell and protect the delicate inner parts of the cell. this cell is fully permeable. it means it will allow all substance to pass in. cell membrane is made up of protein and lipids. it's function is to control what comes in and out of the cell. this membrane is selectively permeable. it means it allows some substance to pass in and others don't. cytoplasm is large sac like structure. most chemical process occur here. chromoplast are the green pigments.
cell wall is only found in plant cell . it is absent In animal cell . the neucleus in the plant cell contain a pigments haemoglobin, which contain genetic information to the cell .
