The first is A second is C
-Crossing over occurs between prophase 1 and metaphase 1 and is the process where homologous chromosomes pair up with each other and exchange different segments of their genetic material to form recombinant chromosomes. It can also happen during mitotic division, which may result in loss of heterozygosity.
The answer is Because the resting plasma membrane is more permeable to potassium
Plasma membrane is more permeable to potassium(kalium) than sodium(natrium) which makes it easier to move between intracellular fluid and extracellular fluid. But the concentration of the ion still regulated strictly by the cell using pump and transporter in their membrane. The pump is doing active movement(against gradient of concentration) and need ATP to do so.
