Answer:
Mitosis
Explanation:
Mitosis is the process of making new body cells
Answer:
A <u>scientific model</u> is a physical and/or mathematical and/or conceptual representation of a system of ideas, events or processes. Scientists seek to identify and understand patterns in our world by drawing on their scientific knowledge to offer explanations that enable the patterns to be predicted.
Answer:
The direction of magnetic field produced by a current carrying wire is given by the right hand thumb rule. If the thumb points in the direction of current the fingers curl along the direction of magnetic field.
further, The red end of the compass needle points in the direction of external magnetic field. As the red end of the needle is pointing away from us, the external magnetic field at its location should also be directed away from us. Using the right hand thumb rule, we can see that this is only possible if the current in the wire is flowing upwards.
Explanation:
Answer: b- covection
Explanation:
Conduction: It is the circulation or transfer of heat through a metal or solid. For example, heat generated inside an enclosure can be transferred to the outer surface by means of conduction.so therefore conduction can not be the answer.
Convection is the circulation or tansfer of heat from a surface by means of a fluid such as air. Natural convection happens when air is heated: it expands, rises, and is replaced by cooler air. The amount of convection may be increased by using a fan to increase the flow of air.Likewise,Ducts are used to circulate air in the system. Since, air is circulated in the system, heat is transfered by convection.Hence,the answer is B-convection.
Radiation: Here, energy is radiated through the air by means of electromagnetic radiation. Since heat transfer through raidation does not involve contact between the heated object and the heated source,so energy is lost as light or through electromagnetic radiation. So C is wrong.
