Answer:
All cells have a nucleus, which acts like the brain of the cell
Explanation:
prokaryotic cells don't have a nucleus
Answer: The two examples of conduction and induction are as follows.
Explanation:
Conduction can be defined as the process of transfer of charges from the charged body to the neutral body by direct contact whereas the induction is a process in which the charges are induced in the neutral body by the charge body. The conduction process requires the direct contact between the bodies in which the charges are being transmitted.
The example of the conduction process involves the neutral metal sphere gets charged when comes in contact of aluminum plate that exhibit a charge.
The example of induction is the rubbing of the rubber balloon with that of the animal fur then the two balloons will move away due to like charge repel each other.
Answer:
The correct option is C.
Explanation:
There are three modes of heat conduction, these are conduction, convection and radiation. Heat transfer by conduction usually involves the movement of heat through solid substances. For instance, in the scenario given in this question, the warm surface is the solid substance through which heat is passed to the insects' bodies. Thus, conduction requires direct contact.
Heat transfer by convection method usually involves the movement of heat through liquids or gases while radiation can occur in vacuum.
