    OKay sure ummm lysosomes obviously have high enzyme activity because they are just vesicles packed with hydrolytic enzymes 2. mitichondria is semi-autonomous organelle that has ribosomeS so obviously enzymes are proteins right so the more the ribosomes the more the hydrolytic activity 3. nuclei...

    GP= NP-R, GP=Gross which is energy produced by plant and NP= energy transferred to primary consumers R= respiration, so 10000 is produced by plant okay which is gross, gross literally means energy converted to chemical energy from light so (1000000-9900000) is 10000 which is light energy...

    Well the net size i presume would be the size of the organisms themselves 7mm= earthworms and beetles 0.5 mm: small invertebrates 0.03mm: microorgansims now look t the question "most important for breaking down", obviously the the ones with greatest difference 100-6=94, so this falls on 7mm...

    Well the answer is D correct me if I'm wrong, okay explanation "W.p of cell = Pressure.p + solute potential". okay so in the middle we have incipient plasmolysis you have to check the images for this, at this point, pressure potential is zero and both the water potential and solute potential...

    Well think of it like this ehm ehm at night transpiration decrease right so the pressure at the leaf would increase right so what you're doing exactly is that you are reducing the pressure difference, its like a straw right you suck on a straw on top the diameter is reduced you stop sucking or...

    Okay for the first Q. multiply each breath rate by the tidal volume this should give you the total Oxygen INHALED NOT ABSORBED in 1 minuite by whoever ok, then you find the diffrence betwwen the value you obtained anf the total lung volume the person with the largest diffrence is the person who...

    Well ummm beans are leguminous plants so nitrogen fixation (mutual relation ship e.g rhizobium bacteria) is going to occur and MORE nitrate ions "eventually" are produce in the soil so more wheat productivity so apparently its not B, C and D, C and D are definitely going to introduce more...

    confused123 its cofactor because a cofactor can either be a coenzyme or ion (prosthetic group), in both cases enzymes need these cofactors to have a complete process of catalysis and so the answer should be B, correct me if I'm wrong.
