Hee Sun drew an electron dot diagram of a silicon atom as shown. S i with 1 dot each above, right, below, left.

In addition to changing the symbol to C, how would this diagram compare with an electron dot diagram of a carbon atom (C)?

The dot to the left of the symbol would be removed in the diagram for carbon.
The same number of dots would appear in the diagram for carbon.
There would be two dots above and to the right of the symbol in the diagram for carbon.
The single dots would be replaced with two dots on each side of the symbol in the diagram for carbon.

The kidney filters potentially toxic substances in the blood, and thus “clears” the blood of those substances. this clearance function is dependent upon and proportional to the diffusion gradient of the substance across filtering capillaries, i.e. if the concentration of the substance is doubled, twice as much will be cleared from each ml of blood that is filtered. suppose that the body produces a constant amount of a substance x per unit of time. the kidneys eliminate substance x at a rate directly proportional to the concentration of the substance and the volume of blood cleared each minute (c): elimination = c × [x], where [x] is the steady-state concentration of substance x. imagine an individual with an initial concentration of x equal to [x]0 who develops kidney disease. her baseline clearance c0 drops to one half of the original (½c0). what is the new steady state concentration of x? (for simplicity, assume that substance x is 100% filtered by the kidney).
