Answer: The direction of an electric current is by convention the direction in which a positive charge would move. Thus, the current in the external circuit is directed away from the positive terminal and toward the negative terminal of the battery. Electrons would actually move through the wires in the opposite direction.
Absorbed light energy is used to convert carbon dioxide (from the air) and water (from the soil) into a sugar called glucose.
Answer:
Meiosis is important because during sexual reproduction, it ensures that all produced organisms have the correct number of chromosomes. It is also responsible for producing genetic variations during the process of recombination, and it repairs some genetic defects.
The disadvantage from not having the trait normally arises only after the reproductive stage of the individual's lifecycle is mostly over. This is a special case of "no strong pressure", because evolution selects genes, not the organism. In other words the beneficial mutation does not alter the reproductive fitness.

Answer:
First a warm front then a cold front.
Explanation:
Cyclone may be defined as the amount of the large air and move around the area that has low atmospheric pressure. The cyclone can cause the large disturbances to the living organisms.
The cyclone formation occurs at the low polar vertices. The two main types of front are related to the cyclone. The warm front first form for the air movement. This warm front is later replaced by the formation of the cold front of that cyclone.
Thus, the correct answer is option (3).
