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.

Answer:
Reasons for the spreading of this illness is due to the fact that people are not wearing their masks, not covering their coughs and sneezing which spreads germs, and during this time coming in close contact with others. To help prevent the spread would be for us to wear masks because not only does it protect us it helps protects people from our germs. Washing hands and covering coughs and sneezes can also help tremendously as well as keeping distance between others. The sooner we all practices these basic things the quicker all of us can get back to our normal lives because almost we know almost everyone misses the normal.
Answer:
Bacteria that have obtained the ability to resist the effects of antibiotics. As the diseases caused by these bacteria are hard to treat.
Explanation:
Darwin proposed that evolution is caused by natural selection.
During the industrial revolution caused tons of soot has been deposited in the countryside around industrial areas. The soot discoloured and generally darkened the surfaces of trees and rocks.
In 1848, a dark-coloured moth was first recorded. Today, in some areas, 90% or more of the-peppered moths are dark in colour. More than 70 species of moth in England have undergone a change from light to dark. Similar observations have been made in other industrial nations, including the United States.
Overusing and misusing of antibiotics causes antibiotic resistance. The ability of bacteria to resist the effects of an antibiotic is known as antibiotic resistance.
It occurs because of overuse and misuse of antibiotics over a long period of time. It also occurs if we do not use it as prescribed.
Antibiotics should not be taken every time we feel uncomfortable. We should not save it for next time and should not share it with others. If we overdose ourselves with it we may have serious side effects which can make us feel worse.
Answer:
Hydra
Explanation:
The mode of nutrition being described in this question is EXTRACELLULAR DIGESTION, in which a food substance is chemically broken down externally. The organisms being portrayed is HYDRA. Hydra is an animal that secretes digestive enzymes that work on the food extracellularly (outside the organism), then absorb the digested food.
Therefore, the organism X observed by the scientist whose mode of nutrition is to secrete enzymes outside its body and digests food with these enzymes, then absorbs the digested food is the HYDRA.
At the end of Kreb cycle 2 molecules of ATP are produced.
<u>Explanation:</u>
Kreb cycle or the citric acid cycle is an important cycle that takes place in the mitochondria to yield energy molecules that is the ATP molecules. Every glucose moiety passes through the glycolysis , then yields pyruvate are produces through the glycolysis which then enters the cirtic acid cycle as acetyl co A and produces 2 ATP molecules. The FADH and the NADH are produced then enters the electron transport chain thereby leading to their conversion to ATP molecules.
