plz mark me branliest
Answer:
smaller single celled organisms have a high surface area to volume ratio cause surface area to the volume ratio smaller as the cell grows larger. if a sell grow beyond the limit not enough material will be able to cross the membrane fast enough to accommodate the increased cellular volume
The mass (in grams) of NaCl required to prepare the solution is 36.27 g
<h3>What is molarity?</h3>
Molarity is defined as the mole of solute per unit litre of solution. Mathematically, it can be expressed as:
Molarity = mole / Volume
<h3>How to determine the mole of NaCl</h3>
- Volume = 200 mL = 200 / 1000 = 0.2 L
- Molarity = 3.1 M
- Mole of NaCl =?
The mole of NaCl in the solution can be obtained as follow:
Molarity = mole / Volume
Cross multiply
Mole = Molarity x Volume
Mole of NaCl = 3.1 × 0.2
Mole of NaCl = 0.62 mole
<h3>How to determine the mass of NaCl </h3>
We can obtain the mass of NaCl needed to prepare the solution as follow:
- Molar mass of NaCl = 58.5 g/mol
- Mole of NaCl = 0.62 mole
- Mass of NaCl = ?
Mole = mass / molar mass
Cross multiply
Mass = mole × molar mass
Mass of NaCl = 0.62 × 58.5
Mass of NaCl = 36.27 g

E. <span> When they stop dividing, they do so at random points in the cell cycle; they are not subject to cell cycle controls; and they do not exhibit density-dependent inhibition when growing in culture.
Hope this helps(:</span>
