In a sample of double-stranded DNA, if the nitrogenous base guanine is 19%, then the nitrogenous base adenine will be 31%
Explanation:
In a double-stranded DNA, the four nitrogenous bases bind and pair together. The purine bases guanine (G) and adenine (A) pair with pyramidine bases cytosine (C) and thymine (T) respectively. The pairing will be between G-C and A-T bases.
According to Chargaff’s Rule, the percentage of each nitrogenous base will be equal in a pair. So the percentage of G will be equal to percentage of C and the percentage of A will be equal to percentage of T.
So if the guanine percentage is 19%, then applying Chargaff’s rule, cytosine will also be 19%
The remaining 68% will be shared with the adenine and thymine pair, of which adenine will be of 31% according to Chargaff’s rule.
GMO foods should be labeled. Why?
GMO foods are mostly common in fruits and veggies. They help prevent from bacteria and superbugs and other insect. And GMO food can save lives of other animal. Which means people who eat that will be ok but the others that eat it will die, caffeine for example is really deadly for other animals but it completely good for humans. That's all i know about it, a chemical that's super deadly but good for human society.
Answer:
the necessary criterion to validate the diagnosis is "at least 1 month of clinically significant distress affecting a person after witnessing or experiencing a traumatic event that affects other parts of his or her life"
Explanation:
posttramatic stress disorder (PTSD):"is a mental health condition that's triggered by a terrifying event — either experiencing it or witnessing it. Symptoms may include flashbacks, nightmares and severe anxiety, as well as uncontrollable thoughts about the event."
Inhalants can be breathed in through the nose or the mouth in a variety of ways, such as—
"sniffing" or "snorting" fumes from containers;
spraying aerosols directly into the nose or mouth;
"bagging" — sniffing or inhaling fumes from substances sprayed or deposited inside a plastic or paper bag;
"huffing" from an inhalant-soaked rag stuffed in the mouth; and
inhaling from balloons filled with nitrous oxide.
