1. Briefly explain why 6mM of potassium chloride (KCH) was introduced to match 9mM of sodium chloride. What concentration of potassium chloride would be used if that of sodium
chloride had been 15mM?
2. When deionized water was used in place of potassium chloride solution, there was no
sodium transport. Describe what would have happened if 6mM potassium chloride solution
was added to the OmM sodium chloride intracellular solution.
3. Upon introducing 400 glucose carrier molecules into the cell membrane, the rate of Na' and
K*transport was unaffected. Explain why such an observation was made.
4. State the mode of transport of Glucose, Na* and K, and explain the rationale behind your
choices of modes of transport, as stated above.

this protocol provides a detailed procedure for nucleoprotein extraction from cultured cells and tissues in an efficient manner.

the two answers are a, the population of birds with large beaks will increase on the island, and c, the trait for large beaks will be passed on to future generations through natural selection. the reason for that is because if the birds that have beaks developed for eating small seeds lose all of their food, they will go hungry and eventually starve because they physically cannot eat the large seeds, therefore making the population of large beaked birds higher. also, if the trait of large beaks are dominant on the island over small beaks, then over time the large beaked birds will reproduce more and more, while the smaller beaked birds will reproduce less and less because they can't survive with the food provided. that leads to the trait of small beaks disappearing and the trait of large beaks taking over the island.

i would answer but it has no question attached to be answer sorry kido
