How does the lysosome membrane better facilitate the function of the organelle? a) diffusion of essential ions against a concentration gradient maintain homeostasis. b) pathogens cannot enter the organelle from the cytosol by diffusion. c) the phospholipid bilayer is hydrophobic which decrease the amount of water entering the cell. d) the membrane contains the acidic environment needed for digestion that could be harmful to other functions within the cell.

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.
