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.
Answer:
c.systemic anaphylaxis
Explanation:.
Anaphylaxis is an allergic reaction. It is life threatening and is very severe and dangerous. People suffers from such allergies when they come in contact with certain food, latex, medicines, insects stings, etc to to which they are allergic to.
When a person is exposed to such allergen, reaction occurs within minutes and if not treated medically with EpiPen injection or epinephrine, it can causes death or unconsciousness.
When Cecilia is stung by a bee, it stared causing reaction in her body. It released a chemical mediators in her body that resulted in the swelling of her throat and she finds difficult to breathe. But when her husband injected EpiPen injection, the EpiPen started to counteracts the response as epinephrine helps to maintain blood pressure and dilates the airways.
Thus the answer is
c.systemic anaphylaxis

Answer:
communication
Explanation:
Based on the information provided within the question it seems that Jessamyn's component about communication is not entirely accurate. This is because she states that "they need to be able to communicate quickly and efficiently" but communication can have many obstacles that do not necessarily pertain to intelligence. An individual or entity can be intelligent and still not be able to communicate because of a difference in dialect between both parties.

There are a lot of weird sleep-related world records out there. From the longest line of human-mattress dominoes—2016 'dominoes' and took 14 minutes for all of them to fall—to the most people served breakfast in bed at once—418 people in 113 beds set up on the lawn of a Sheraton Hotel in China. But there's one record that remains elusive: who holds the record for longest consecutive slumber?
Tough to call
The length of time someone is actually asleep is pretty tough to measure, which is what has kept the official title out of the hands of sleepers around the world. That doesn't mean, however, that there have been no valiant attempts—though they don't really count as real sleep.
In October of 2017, Wyatt Shaw from Kentucky fell asleep for 11 days. He was just seven years old and doctors ran several tests with no conclusive explanations. Wyatt did wake up with cognitive impairment, particularly when walking and talking, but made a full recovery after treatment with drugs typically used in seizure management.
In 1959, UK hypnotist Peter Powers put himself under a hypnotic sleep for eight straight days. It made quite the splash in European media and radio shows, but doesn't quite count as sleeping.
