Because you could easily contaminate the results of the urine if you don't follow exactly what the strict rules dictate This could be a very dangerous thing because if you contaminate the results, then other doctors would think that the patient has some disease that needs to be taken care of which in reality they do not. The patient could also have to go through things or waste money on things that they don't need to because there was something in the urine that wasn't supposed to be there which was added because they didn't follow the strict rules. Then the doctor who contaminated it could be sued for malpractice which is never a good thing.
Answer:
3) Temperature
4) gill covering opening and closing per minute
5)as temperature rises, the rate of gill covering opening and closing per minute increase until the temperature reaches 27℃ where the rate decreases
Explanation:
4) you can adjust and control the temperature in an experiment
5) you can't control the gill opening and closing rate
The answer is benedict’s reagent. Benedict’s
test is used to detect reducing sugars in solution when heated. The color
change occurs from clear blue to a brick-red precipitate in the presence of the
reducing sugars. The cupric compounds in
the benedicts reagent react with the reducing sugars (enediols) produced from
heating of the reducing sugars in the presence of an alkali. Benedict's reagent is comprised of a mixture of sodium citrate, sodium carbonate, and
copper(II) sulfate pentahydrate.
Answer:
echolocation
it sends waves for them to see around them.
Explanation:
Answer:
A = Activator
B = Effector
Explanation:
An activator is a protein which typically binds to a short (50–1500 bp) region of DNA which might be located either upstream (mainly) or downstream of a gene so as to cause increased transcription. This particular region of DNA is known as enhancer and activator is also known as transcription factor. Activator is a trans-acting factor which binds to the cis-acting factor which is enhancer so as to enhance transcriptional expression.
But another protein named as effector may restrict activator from binding to the enhancer leading to a decrease in transcriptional expression by binding to the activator allosterically. Allosteric binding of effector to the activator causes conformational change in activator so it can no longer bind the enhancer.
