Answer:
The magnetic field due to a solenoid is given as : where, is the permeability of the medium. n is the number of turns or loops in the coil. I is the current flowing in the solenoid.
The magnetic field due to a solenoid can be increased by increasing the number of turns, current and placing an iron core inside the solenoid.
So, the correct option are:
(1) using more wire loops
(2) using a larger current
Hence, the correct options are (a) and (c).
Some of the organisms have evolved in such a way that they remain inactive when the predator populations are active.
Adaptive theory of sleep suggests that the prey population prefer to sleep when (in this case, at night) the predators are most active. The prey population use this time in taking rest and restoring energy for other works. As the prey population is inactive and remained protected in safe places, they are less likely to be predated.
Hence, the correct answer is adaptive theory of sleeping.
D because kg is mass and cubic cm is volume which Density = Mass / Volume
Answer:
D. It is not a superordinate goal because it did not require both pet store owners to accomplish.
Explanation:
In this case, both pet stores are benefited and therefore it corresponds to a superordinate goal.
I would say B.(RNA is singled stranded, DNA is double stranded, so
RNA is smaller than DNA.)
RNA is a single strand and can leave the nucleus easily but the DNA is double strands that are twisted together and are big and cannot leave the cell
