2. The following results were obtained over a 24 hour period: Calculate (5 points for each part, 40 points total): a.) The clearance, Cx, of inulin, urea, and PAH b.) ERPF c.) The rate of urea filtration d.) The rate of urea excretion e.) The rate of urea reabsorption, given that urea is not secreted f.) The rate of PAH filtration g.) The rate of PAH excretion h.) The rate of PAH secretion (assuming no PAH is reabsorbed)

tsd is temerature dependent sex determination.

tsd: it is a type of environmental sex determination in which the temperature experienced during embryonic/ larval development (ambient temperature for development) determine the sex of the offspring.

crocodile displays the tsd where the ambient temperature of the developing egg determines the individual's sex. for example in the american alligator's eggs, incubation at 33 ºc produces mostly males, while incubation at 30 ºc produces mostly females. so if the american alligator's egg will get the ambient temperature (33 degree celcius)during embryonic development from egg, the offspring will be male and same for the female sex determination.

evidence and logical support is essential for a scientist to do in order to maintain credibility. this is because no one can believe without any logic and without any evidence.hence a scientist can maintain credibility by proving himself and by answering logically so experiments prove very beneficial. logical hypothesis give conclusion which is acceptable. therefore, there are two main factors to maintain credibility by a scientist is evidence and logical support.
