Answer : Option B) <span>A liquid conforms to the circular area of the beaker, and this area multiplied by the liquid’s height equals its volume.
Explanation : When a liquid is poured into a beaker the liquid takes the internal shape of the beaker which is circular in shape, according to the markings on the beaker one can measure approx quantity of fluid required and perform the experiment. The area of circular of the beaker when multiplied with height of liquid gives the total volumes of fluid present in it.

Answer:
365.4 g/mol is the molar mass of this gas.
Explanation:
Using ideal gas equation:
PV = nRT
where,
P = Pressure of gas = 0.98 atm
V = Volume of gas = 1.5 L
n = number of moles of gas = ?
R = Gas constant = 0.0821 L.atm/mol.K
T = Temperature of gas = 287 K
Putting values in above equation, we get:
Moles of gas = n = 0.06239 mol
Mass of gas = m = 22.8 g
Molar mass of gas = M
365.4 g/mol is the molar mass of this gas.
-Plant cells have cell walls to keep the cell rigid, but animal cells don't
-Plant cells have a large permanent vacuole, but animal cells don't. Animal cells will either have a small vacuole or none at all.
-Plant cells have chloroplasts, which contain chlorophyll, so photosynthesis can take place. Animal cells don't need to photosynthesise and therefore do not need chloroplasts.
-Animal cells contain flagella, but in plant cells flagella is only found in gametes(sex cells)
