An electromagnet is a device in which moving electric charges (current) in a coil of wire create a magnet. What’s one advantage
belka [17]

Electromagnets can easily be turned on and off.

Explanation:

An electromagnet produces magnetic field which is done by the electric current. These electromagnets contain a wire would like a coil. The current passes through the wire and the magnetic field is concentrated in the center which is the "center of the coil".

When the current is "turned off" the magnetic field "disappears". This shows that we have can have a control over the passage of current or the magnetic field. Thus, the "main advantage" of the electromagnet is that it can be easily turned on and off whenever necessary.

Which of the following best describes the main purpose of the combined processes of glycolysis and cellular respiration?1 breaki
max2010maxim [7]

Answer:

4. transforming the energy in glucose and related molecules in a chemical form that cells can use for work

Explanation:

Glycolysis breaks down glucose into two molecules of pyruvate which is transformed into acetyl CoA to enter the Kreb's cycle. Kreb's cycle breakdown the acetyl CoA into CO2 and H2O. The energy stored in the glucose molecule is released during glycolysis and Kreb's cycle. The released energy is stored in the form of NADH and FADH2 as well as in few molecules of ATP.

The NADH and FADH2 enter the final step of cellular respiration, the oxidative phosphorylation. Here, NADH and FADH2 are oxidized with the help of electron transport chain (ETC). During the transfer of electrons through ETC, the proton motive force is generated which then helps in ATP synthesis.

Hence, the three steps of cellular respiration (glycolysis + Kreb's cycle + oxidative phosphorylation) retrieve the energy from nutrients such as glucose and store it in the form of ATP. ATP is used by cells as an energy source for various other functions.

Ovules produced by an entirely green plant contain a rare mutation in a nuclear gene that is involved in chlorophyll synthesis,
sveticcg [70]

Answer:

The plant will produce less chlorophyll

Explanation:

The plant still has a functional allele provided by the paternal gamete, thereby the leaves have this enzyme required for chlorophyll biosynthesis. In consequence, the plant can produce chlorophyll pigment but in less quantity, since it has only a functional allele coding for a key enzyme involved in the chlorophyll pathway
