Answer:

To study these moths, Dr. Kettlewell placed light and dark moths on the trunks of trees where he could observe them. The same birds would find the dark moth twice as often if the bark on the tree was light. This supported the idea that dark moths had a survival advantage in a dark forest.

Answer:

There are no options in this question but generally a sample of DNA can be increased;

By using Polymerase Chain Reaction (PCR) technique.

Explanation:

This question describes the application of making molecular biology to solving a crime problem; a branch called forensics. In this case where an insufficient small amount of DNA sample was recovered from the blood in a crime scene, the polymerase chain reaction technique, commonly known as PCR can be used to increase the DNA sample.

In the 1980's, a molecular technique used to amplify part of a template DNA strand to produce several copies of it, was invented by Kary Mullis and his colleagues. This amplification refers to the numerical increase in the number of DNA sequence.

stira [4]
A decreased pH coupled with a decreased plasma concentration of bicarbonate ion indicates that acidosis is occurring and the respiratory system will compensate for this change.  
<span>Acidosis (metabolic) is a state when increased acidity in the blood occurs and it usually refers when arterial pH falls below 7.35. Metabolic acidosis may result from increased production of metabolic acids (lactic, for example) and is characterized by low pH, low blood HCO3, and normal or low PaCO2. Metabolic acidosis is compensated with an increased exhalation of CO2 to reduce metabolic acid.</span>
