The earth is made up of many interacting system which are quite dynamic in nature. The earth is sub divided into four components which are THE ATMOSPHERE, THE HYDROSPHERE, THE BIOSPHERE AND THE GEOSPHERE. These are the separate systems that made up the earth system.
The hydrosphere is make up of all the water components on the earth surface and how the water cycle through nature. The atmosphere refers to the layers of gases that surround the planet earth while the biosphere refers to the living components on the earth surface. All these systems interact together to keep life existing on earth.

The electrical impulse travels across the axon, and the myelin sheath helps to increase transmission speed.
The organelle which is most likely to be missing from leaf cells is Lysosomes.
Lysosomes are an important organelle for eukaryotic animal cells as they contain the digestive enzymes. The macromolecules or foreign matter which are harmful for the cells enter the animal cells easily but not the plant cells as the plant cells contain cell walls. Phagocytosis or digestion of macromolecules is not much needed in plant cells so a lysosome can be missing from the leaf cell.
Answer:
Penicillin is hydrolyzed and thereby rendered inactive by penicillinase (also known as β-lactamase), an enzyme present in some resistant bacteria. the mass of this enzyme in staphylococcus aureus is 29.6 kd. the amount of penicillin hydrolyzed in 1 minute in a 10-ml solution containing 10-9 g of purified penicillinase was measured as a function of the concentration of penicillin. assume that the concentration of penicillin does not change appreciably during the assay. penicillin(μm) amount hydrolyzed(nmol) 1 0.11 3 0.25 5 0.34 10 0.45 30 0.58 50 0.61 (a) plot v0 versus [s] and 1/v0 versus 1/[s] for these data. does penicillinase appear to obey michaelis-menten kinetics? if so, what is the value of km? (b) what is the value of vmax? (c) what is the turnover number of penicillinase under these experimental conditions? assume one active site per enzyme molecule.
