All of the following statements about homeotic genes are correct except group of answer choices homeotic genes were first identified in invertebrates, but their homologues were found in almost all organisms. all homeotic genes contain consensus sequence that result in specific dna-binding motif. in vertebrates, homeotic genes are organized into two distinct clusters. all homeotic genes encode transcription factors that direct further gene expression. homeotic genes exhibit a relationship between their order on the chromosome and the timing of their expression.

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).
