Chlorine is micronutrients, too much chlorine may lead to toxicity in plants, it can result in to burned appearance in leaves.
<h3>What are micronutrients? </h3>
The nutrients which are less Essential to plants for there growth. For example Boron, chlorine, mangnese, molybdenum, iron, zinc.
Chlorine is also on of micronutrients , it not that much essential and if there is too much chlorine it can lead to brown or dead tissue on the tips ,margins between the veins of leaves.
As she has put chlorine in plants without the particular amount needed the plant ,so the plants lead to toxicity. And the fifth plant do not contain any chlorine it is alive.

The chemical reactions that absorb energy are called endothermic reactions. These reactions absorb more energy than they release. From the given options endothermic reactions are: respiration in cells, photosynthesis, activating a cod pack
The chemical reactions that release energy are called an exothermic reactions: producing electric current, burning a candle, baking bread.
Action potential is a mechanism of transfer of ions across the plasma membrane down their elctrochemical gradient. Action potential is regenerated by the influx of ions such as sodium in case of voltage gated sodium channels. The voltage gated channels can be either open or closed depending on the action potential. Depolarization of membrane leads to the opening of these channels that allow the sodium ions to enter the cell down their electrochemical gradient. The threshold of action potential is reached when the entry of sodium ions out reach the exit of potassium ions from the cell. This leads to the generation of action potential.
Answer
The statement that best describes the next step in the formation of the sun is
3. The cloud spins faster as it collapse
Explanation
The Sun is made up hot plasma having internal convective motion which generates a magnetic field through the dynamo process. According to scientists, the Sun was formed from a giant rotating cloud of gas and dust called the solar nebula. The nebula collapsed due to force of gravity on it causing it to spun faster and flattened the disk. Material was then pulled towards the center to form the sun.
