Since models are simpler than real objects or systems, they have limitations. a model deals with only a portion of a system. the carbon cycle model seen here has limitations and does nor include all pertinent aspects of carbon cycling. what is absent from this model of the carbon cycle? a) it does not show the critical role the oceans play in the storage of carbon. b) it does not show the movement of carbon from one sphere to another in the earth system. c) it does not show the increasing human population and their activities have a tremendous impact on the carbon cycle. d) it does not show the movement of carbon from one storage reservoir to another. one example is the movement of carbon through producers and consumers.

C)It does not show the increasing human population and their activities have a tremendous impact on the carbon cycle.

Explanation:

an active site is a region that is present on an enzyme where the reactants or the substrate molecules we can say bind and experience a chemical reaction. the substrate is basically a reactant whose concentration is changing and that is converting into a product after binding at the active site of an enzyme

a

explanation:

many plants naturally reproduce this way, but it can also be induced artificially. horticulturalists have developed asexual propagation techniques that use vegetative plant parts to replicate plants. success rates and difficulty of propagation vary greatly. monocotyledons typically lack a vascular cambium and therefore are harder to propagate.
