Well, it's important to be able to do this because school requires us but knowing plants may open you to know that they are our oxygen, they are essential in our lives. They take in carbon dioxide and release oxygen for us to breathe.
The answer is "<span>c. Ozone in the troposphere is beneficial to living organisms."
because options a, b and d are true about ozone layer.
</span>
Ozone layer is the area of the upper atmosphere, between around 15 and 35 km over Earth's surface, containing generally high groupings of ozone particles (O₃). Roughly 90 percent of the environment's ozone happens in the stratosphere. The ozone layer successfully squares all sun oriented radiation of wavelengths under 290nm from achieving Earth's surface, including certain kinds of UV and different types of radiation that could harm or kill most living things.
<span>The lac operon has three genes that encode for proteins that break down lactose into galactose and glucose. When there is no lactose around, it wouldn't make sense for the prokaryote to make these proteins as it would be a waste of energy. So, when there is no lasctose around, the lac repressor binds the operator region of the operon, which inhibits RNA polymerase's ability to bind and start gene expression. However, when lactose is available, it binds to the lac repressor and deactivates it via allosteric inhibition. Once the lac repressor is gone, the genes can be transcribed into mRNA which can be translated into proteins which can go and break down the lactose. </span>
Finding the reactions in the equation 2KCIO3(s)-2KCI (s)+ 3O2 (g) A 2KCIO3 B 2KCI and 3O2 C 2KCI D.....well first look for the synthesis reactions which are if two different elements are one one side and a compound on the other side where the elements form....the next reaction you would look for would be the decomposition reaction.....and I still don't see this because if I did it would be the same as the synthesis reaction except it would be the other way around...sooo the compound of the elements would be on the right and when you add the elements it would be on the left side....the next reaction is the single displacement which I don't see in this example...the single displace me is when you are adding the elements not the left and on the right it's the same thing BUT the elements are in different order....and the last one is the combustion reaction which I do see....this is when there is adding element on both side.......so the reactions I see in this example is the combustion reaction.....hope it helps....:)
The answer is cancer drugs. According to a united nations University Report, almost 62 percent of all discovered and distributed cancer drugs have been made or derived from the discoveries of medicinal plants. Cancer Drugs are usually made from Medicinal Plants, because they contain more effective effects than other substances.
