I believe the statement would be that, A magnetic field created by the electric current causes the compass needle to move.
An electric current through a conductor creates a magnetic field,such that when a charged particle such as an electron, proton, or ion is in motion, magnetic lines of force rotate around the particle. Since current moving through the wire consists of electrons in motion, there is a magnetic field around the wire, which causes the compass needle to deflect.
Answer:
Option B, It increases the probability that some offspring will survive long enough to reproduce.
Explanation:
The larger the number of eggs, the larger will be the available opportunities for at least few of the youngsters to develop into adult being and survive till the age of fertility. This shall enhance the chances of producing new offspring before the older one dies thereby replacing them without changing the population number and further producing offspring that can survive to replace them and continue this chain.
Hence, option B is correct
Answer: Water, in its many forms, moves all over the Earth. Water vapor moves with the air currents, falling as rain from the clouds. Frozen glaciers creep slowly down from polar regions, then recede as they warm and melt. Liquid water moves from rushing rivers to ocean currents or to groundwater.
The water, or hydrologic, cycle describes the pilgrimage of water as water molecules make their way from the Earth's surface to the atmosphere and back again, in some cases to below the surface. ... Earth's water continuously moves through the atmosphere, into and out of the oceans, over the land surface, and underground.
