Electromagnets can be switched on and off. This is good in a scrap yard because they need to pick heavy pieces of metal and then drop it.

Answer:

The prime advantage of using electromagnets in a device is that it can be easily turned on and off.

Explanation:

The formation of electromagnets is done by winding a wire via a magnetic substance and then passing an electric current through it. The durability of the electromagnet relies upon the size of the electric current via the coil and the number of coils.  

On the other hand, the regular magnets do not need power, however, it is reliant upon the kind of material that is, used to produce it. Thus, it is advantageous to utilize electromagnets in comparison to permanent magnets as the strength of the electromagnet can be amended easily by monitoring the concentration of current flowing through it. Thus, it is easy to turn off and on any device containing an electromagnet.

Which of the following statements about transposable genetic elements is NOT true?
Katarina [22]

Answer:

C. They all use a cut and paste mechanism.

Explanation:

DNA transposons can go through a replicative or nonreplicative transposition.

The replicative transposition uses a "copy and paste" mechanism that consists of the introduction of a new copy of the transposable element in a new position, meanwhile <u>the old copy remains in the original position</u>. This determines an increase in the number of copies.

The nonreplicative transposition uses a "cut and paste" mechanism that consists of the cleavage of the transposable element from its position and its <u>insertion in a new position</u> without increasing the number of copies.

Retrotransposons, on the other side, move through RNA intermediates generated by the reverse transcriptase.

A frog with a mass of 0.29kg hops up in the air. At the highest point in the hop, the frog has a gravitational potential energy
PtichkaEL [24]

Answer:

0.27m

Explanation:

To get the energy

Potential energy= Mgh

M is Mass

G is acceleration due to gravity

H is height..

M= 0.29kg, h= ?

P=0.759. g=9.8m/s

Therefore,

0.759=0.29×9.8×h

H= 0.759÷2.842

H= 0.27m
