c
Explanation:
A water molecule has three atoms: two hydrogen (H) atoms and one oxygen (O) atom.
Answer:
Selectively permeable or semipermeable means specific substances are allowed to pass through the plasma membrane.
Explanation:
The plasma membrane is selectively or semipermeable in nature because the plasma membrane allow only specific molecules such as nonpolar substances or hydrophobic substances such as steroidshormone to pass through it and prevent the passage of polar solute molecules such as water,glucose.
To transport these polar solutes across the membrane an additional protein is needed in case of transport of water channel protein is needed whereas in case of glucose transport carrier protein is required.
Answer:
22 cells
Explanation:
The concentration of numbers of cells = 6.74 x 10⁶ cells/ml
Dilution stages includes = 1:100 ; 1:100 & 1:3
The consecutive dilution stages can be calculated as:
= (6.74 x 10⁶) × (1/100)(1/100)(1/3)
= 222.42 cells/ml
= 2.22 × 10² cells/ml
So after addition 0.1 ml of the final dilution to a spread plate, the number of CFUs ( Colony forming units) we expect to count will be:
= (2.22 × 10² cells/ml)(0.1 ml)
= 22.2 cells
≅ 22 cells.
