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.

The primary purpose of the basic economic order quantity model is
AleksAgata [21]

Answer:

D. to minimize the sum of setup cost and holding cost e. to calculate the optimum safety stock

Explanation:

Economic order quantity ( EOQ ) is formulated as :

EOQ= \sqrt[]{\frac{2C_O D}{C_h} }

Co = Ordering cost

D = annual demand

Ch = Annual unit holding cost

Economic quantity is the order quantity which minimizes sum of annual cost of ordering and annual inventory holding cost  so to minimize the overall cost of the inventory.

ANSWER : d) to minimize the sum of setup cost and holding cost that is to calculate the optimum safety stock.

Distinguish between directional, stabilizing, and disruptive selection. Give examples.
pashok25 [27]
Directional selection is a type of natural selection that favors one extreme phenotype over the mean or another extreme. Examples of directional selection include giraffes that have long necks and the darkening of London's peppered moths after the Industrial Revolution.

Stabilizing selection, also known as purifying selection, is a type of natural selection in which genetic diversity decreases as the population stabilizes on a particular trait value. An example of stabilizing selection is birth weigh in humans.

Disruptive selection is a type of natural selection that shows a preference toward the reproduction of genetic material at the extremes within a population.One of the most studied examples of disruptive selection is the case of ​London's peppered moths.
