Q:

Is Osmosis Active or Passive?

Answer

Osmosis is the process in which water molecules move from a region of higher water potential to a region of lower potential down a water potential gradient across a partially permeable membrane. It doen't requires any additional energy to do this work. 


So, Osmosis is a Passive.


 


Active and passive transport processes are two ways molecules and other materials move in and out of cells and cross intracellular membranes.


1. Active transport is the movement of molecules or ions against a concentration gradient (from an area of lower to higher concentration), which does not ordinarily occur, so enzymes and energy are required.


2. Passive transport is the movement of molecules or ions from an area of higher to lower concentration. Passive transport occurs because of the entropy of the system, so additional energy isn't required for it to occur.



3. Active transport requires energy to proceed, while passive transport does not require the input of extra energy to occur.

Q:

Solid Carbon dioxide is known as

A) Wet Ice B) Dry Ice
C) Solid Ice D) None
 
Answer & Explanation Answer: B) Dry Ice

Explanation:

Dry ice or Cardice is the solid form of Carbon dioxide.

 

1. It has an advantage of lower temperature than the water ice and doesn't leave any residue.

 

2. The reason why it is called as Dry ice is because unlike the normal ice, it won't melt into liquid form. It directly evaporates into the air as gas. That is Solid to gas form passing through liquid state is a phenomenon called as Sublimation.

 

3. The primary use of dry ice is as cooling agent.

Answer & Explanation Answer: C) Red

Explanation:

The visible colors from Longest wavelength to Shortest wavelength are :: Red, Orange, Yellow, Green, Blue and Violet.

                    Red > Orange > Yellow > Green > Blue > Violet.

 

1. Infrared radiation has a longer wavelength than visible Red light.

 

2. Ultraviolet radiation has a shorter wavelength than the visible violet light. 

 

3. The white light is a mixture of the colors of the visible spectrum.

Q:

7, 11, 19, 35, ?

Find the next number in the given number series?

A) 131 B) 94
C) 83 D) 67
 
Answer & Explanation Answer: D) 67

Explanation:

Here the given series 7, 11, 19, 35, ?

follows a pattern that (x 2 - 3) i.e,

7

7 x 2 - 3 = 11

11 x 2 - 3 = 19

19 x 2 - 3 = 35

35 x 2 - 3 = 67

67 x 2 - 3 = 131

 

Hence the next number in the given number series is 67.
