A solution is a mixture where the individual components cannot be made out.
Sugar dissolves in water, which results in a mixture of sugar and water. When the sugar dissolves, it is invisible to the human eye, but still exists at a molecular level. This makes the mixture a solution, as you cannot separate the sugar from the water visibly. The answer will be D) A mixture of sugar and water.
<u>Answer</u> :- Step 1 Receptors (sense organs, muscles, glands, etc.) receive stimuli from the environment or from inside your body.
Step 2 The central nervous system processes information received from the peripheral nervous system.
Step 3 The central nervous system sends out the processed information to the peripheral nervous system.
Step 4 The peripheral nervous system sends a message to the body part that needs to respond so you can react appropriately to the stimulus.
<u>Explanation</u>:-
- There are two different parts of the nervous sytem-the peripheral nervous system (PNS) and the central nervous sytem (CNS).
- The <em>CNS</em> consists of the brain and the spinal cord .
- The <em>PNS</em> consists of all the nerves that lie outside the CNS.
- The main function of the PNS is to gather information from the <em>sensory receptors</em> located in our body and convey this information to the central nervous system.
- The CNS collects this information from the PNS and then interprets it. The interpreted information is then relayed back to the body parts via the PNS to perform the appropriate action.

Answer:
Option (3)
Explanation:
The continental crust is usually thick because it has an average thickness of about 35-40 km. In the high mountain ranges, it is the thickest, forming about 80 km on an average. These are formed when two continental plates form a sandwich pattern by sharing a convergent type of plate boundary.
For example, the thickest part of the crust is the Mt. Everest which lies in the great Himalayan range, which has started to form about 50 million years back. It is geologically the most recent mountain range.
The older mountains are continuously eroded in the geological past, as a result of which the height of the mountains is affected.
Thus, the correct answer is option (3).
Answer: between the second and
third finger
The correct method of removing
a glass stopper is to grasp it between the second and third finger with the
help of the thumb. If the glass stopper is stuck, you can use the tap method by
using many gentle tap and keep on turning the flask. Another technique is to put
oil or use a flame to expose it to heat.
