The following are steps which incompletely describe the mechanism by which Na+ and K+ ions are transported by the (Na+—K+)—ATPase. What is the correct sequence for the events listed, assuming that K+ ions have just dissociated? 1. The phosphate group on the protein is hydrolyzed. 2. ATP binds to the protein. 3. The protein's conformation changes, exposing K+ binding sites to the cell interior. 4. Na+ ions dissociate.

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.

substitution is the answer in this case

when you breathe in, or inhale, your diaphragm contracts (tightens) and moves downward. this increases the space in your chest cavity, into which your lungs expand. the intercostal muscles between your ribs also enlarge the chest cavity. they contract to pull your rib cage both upward and outward when you inhale.
