Option D
polymerase chain reaction (PCR) do Makes more copies of a sample of DNA
<u>Explanation:</u>
A procedure to create several portraits of a distinct DNA section is termed as Polymerase chain reaction. In other words, it is a lab routine handled to compose various representations of a portion of DNA. PCR is extremely explicit and can be utilized to increase, or model, a particular DNA destination from a hybrid of DNA particles.
In PCR, the effect is regularly cycled within a range of temperature variations, which deduct countless models of the destination range to be exhibited. PCR intends to obtain sufficient of the objective DNA region that it can be examined or applied in some other way.
Prediction! hypothesis consists of very little evidence. kind of like a guess
D the discovery of genes changed how scientists think about life
Hydrophilic means that it likes water so it will easily break down in water
hydrophobic will do the opposite and repel water
Osmolality tests is performed to determine the level of a certain nutrient present in the blood and urine.
What is osmolality test?
Osmolality tests measure the level of certain substances in blood, urine, or stool.
The level of glucose(sugar), urea( waste product made in the liver), sodium, potassium, and chloride are measured in osmolality test.
Osmolality test is also performed to check the balance between water and certain chemicals in blood.
Osmolality test also done to diagnose dehydration .
Therefore,osmolality test is done to determine the level of a certain nutrient in blood or urine sample.
