The water molecule is amphoteric (it acts both as an acid and base). It is the perfect medium for biochemical relations occurring in cells. It acts as:
- An Alkali
- An Acid
- A Solvent
- A steroid molecule
- c
-
Amphoteric means a substance that can act both as an acid and as a base.
Ulva belongs to which group?
- Oomycota
- Algae
- Sea Lettuce
- Protozoa
- c
-
Ulva is a green, simple and multicellular organism. It lives in water. It performs photosynthesis.
It is commonly called Sea Lettuce because it looks like lettuce.
Mitochondria are passed to as animal only by:
- Father
- Sister
- Mother
- Both A and C
- c
-
Mitochondria are the Powerhouses of the cell. They take food and turn into energy that cell can use. Its fact, without Mitochondria cell cannot work or survive.
Mitochondria have their own DNA
A protozoan that have both animal and plant like characteristics is:
- Ulva
- Chlorella
- Phytopthora infestans
- Euglena
- d
-
Euglena is like a tiny green animal.
Which of the following cannot conduct electricity?
- NaCl (Solid)
- NaCl (Molten)
- NaCl (Aqueous)
- Both B & C
- a
-
In NaCl, Ions are fixed in place or in solid form and cannot move.
In NaCl (Molten / Melted), Ions are free to move and electricity can flow.
NaCl (Aqueous / dissolved in water), Na and Cl can dissolved in water and can carry current.
The molar volume of CO2 gas is 22.4 dm3 at:
- 25 C and 2 atm
- 0 K and 1 atm
- 25 K and 0.5 atm
- 0 C and 1 atm
- d
-
1ATM (atmosphere) is a normal air pressure at sea level.
1ATM is equal to 760 Torr.
In simple words atm is unit of Pressure.
The space (volume) that 1 mole of a gas takes is called molar volume.
CaCo3 is a polymorph and exist in two crystalline form:
Viscosity of liquid increases with the decrease in:
- Temperature
- Intermolecular forces
- Atmospheric pressure
- Molecular mass
- a
-
Viscosity is the resistance of liquid to flow.
Which one of the following is not a state function?
- Temperature
- Work done
- Internal energy
- Pressure
- b
-
Temperature, Internal Energy and Pressure are state functions.
