Answer:
The correct option is<u> B.adhesion</u>
Explanation:
A molecule of water is made up of a hydrogen atom and two oxygen atoms. The water is a polar molecule; hydrogen ions carrying a positive charge and oxygen atoms carrying negative charge. The negatively charged oxygen atom of one molecule will attract the positively charged hydrogen atom of another water molecule. Hence, developing the forces of adhesion or hydrogen bonds. This forces of adhesion pull the water upwards when water is lost by leaves through transpiration.
Hi! so yea C. Nerves stimulated, hypothalamus signals muscles and skin, shivering and vasoconstriction activated, temperature falls
Answer: The charges of the objects are A: Positive and B: Negative.
Explanation-
The electric field lines are pictorial representation of the electric field in terms of imaginary lines.
The direction of electric field is away from the positive charge and is directed towards the negative charge.
In this question, the electric field lines are emerging from A and coming towards B.
Thus, the right answer is A: Positive and B: Negative.
I think it’s c. Hope you get it right!
