Answer:
The correct answer is <em>A. real-time PCR can measure the amount of DNA amplified as the reaction proceeds, while standard PCR cannot.</em>
Explanation:
PCR (Polymerase Chain Reaction) is a molecular biology technique. Conventional PCR and real-time PCR are diferent types of PCR, and are both used to exponentially amplify DNA molecules. In both types, a polimerase enzyme is employed to sinthesize DNA copies. The main difference is that conventional PCR is qualitative whereas real-time PCR is quantitative. So, real-time PCR permits not only to detect and amplify DNA but also permits to perform a quantification of the target DNA. This is accomplished by measuring a fluorescence signal - which is directly the amount of DNA amplified- during the course of the reaction.
EcosystemTropical Savanna is found between sections of tropical rain forest and deserts. They have 2 seasons; wet (constant humidity) and dry (long periods of dry spells and drought that may cause fires).
Both savanna buffalo and forest buffalo live close to water. The buffalo are found throughout the northern and southern savanna as well
as the lowland rain forest.
<span>How might this population suddenly increase? How might this affect the ecosystem? If there was an increase in population; grasslands during the wet season will be gone, more predators will flock for an abundance of buffalo.
</span>
<span>What might happen to the ecosystem if this population was removed? If you remove the buffalo from the savanna ecosystem, it can cause a ripple effect such as populations of small mammal (mouse) will double, which will attract more snakes (venomous), it can cause the flea and tick population to increase, and the increase in tick/fleas can cause the risk of transmission of flea/tick borne pathogens.</span>
Answer:
A blizzard can form when warm air combines with a high pressure system.
Explanation:
A high pressure zone is defined by cold air mass that has higher density than surrounding air mass. Therefore when a warm air current blows towards the high pressure system, the warm air mass rises over the cold air mass of the high pressure system.
The warm air begins to cool at the front between the cold air mass and warm air mass. Usually for a blizzard to occur the cold air mass is usually below freezing point temperatures. Therefore the moisture in the warm air cools and freezes into snowflakes. This is why the winds of a blizzard are accompanied by snowflakes akin to a winter storm.

Longitude is used to measure distances in degrees from the Prime Meridian. The correct option among all the options that are given in the question is the second option. The main purpose of longitude is to determine the east and west position of a point based on its geographical coordinate. I hope the answer helps you.<em />
Light receptors within the eye transmit messages to the brain, which produces the familiar sensations of color. Newton observed that color is not inherent in objects. Rather, the surface of an object reflects some colors and absorbs all the others. We perceiveonly the reflected colors.
