FILTRATION When the substances in a mixture have different particle sizes, they are separated by filtration. The mixture is poured through a sieve or filter. The smaller particles slip through the holes, but the larger particles do not.p
Answer:
Option A = it dies
Explanation:
Homeostasis:
It is the ability of organisms to maintain the equilibrium in its internal environment in order to deal with external environmental changes.
If the unicellular organism cannot maintain the homeostasis it would die.
Importance of homeostasis:
It is constant chemical and physical condition of cell. The unicellular organisms in maintained homeostasis condition can grow and reproduce. They respond to the environment and transfer energy. It is the primary objective of unicellular organism other wise they would not survive.
It is very important for them because they totally rely on it and can perform the necessary functions of life.
While in case of multi cellular organisms all cells communicate with each other to maintain the homeostasis.
Answer:
138g/mol
Explanation:
K₂CO₃ is also known as potassium carbonate. It has a molar mass of around 138.21 g/mol (138.2055 g/mol to be exact).
Answer : The freezing point of the solution is, 260.503 K
Solution : Given,
Mass of methanol (solute) = 215 g
Mass of water (solvent) = 1000 g = 1 kg (1 kg = 1000 g)
Freezing depression constant = 
Formula used :
where,
= freezing point of water = 
= freezing point of solution
= freezing point constant
= mass of solute
= mass of solvent
= molar mass of solute
Now put all the given values in the above formula, we get
By rearranging the terms, we get the freezing point of solution.
Therefore, the freezing point of the solution is, 260.503 K
