What does the PCR do

Biology
1 answer:
schepotkina [342]2 years ago

Answer: It is a technique used to amplify a segment of DNA of interest or produce lots and lots of copies. In other words, PCR enables you to produce millions of copies of a specific DNA sequence from an initially small sample – sometimes even a single copy. (looked it up on google lol)

Outline the process of the Carbon Cycle.
Bond [772]

Answer:

Carbon Cycle Definition

Carbon cycle is the process where carbon compounds are interchanged among the biosphere, geosphere, pedosphere, hydrosphere, and atmosphere of the earth.

Carbon Cycle Steps

Following are the major steps involved in the process of the carbon cycle:

Carbon present in the atmosphere is absorbed by plants for photosynthesis.

These plants are then consumed by animals and carbon gets bioaccumulated into their bodies.

These animals and plants eventually die, and upon decomposing, carbon is released back into the atmosphere.

Some of the carbon that is not released back into the atmosphere eventually become fossil fuels.

These fossil fuels are then used for man-made activities, which pumps more carbon back into the atmosphere.

Hope it helps!!!

In a fish species, the number of eggs that hatch and survive for one year varies depending on the number of eggs that were produ
Alenkinab [10]

Answer:

C. The chance of survival decreases when there is intraspecific competition for resources among surviving yearlings

Explanation:

The survival rate of the offspring of the fish species will decrease as a result of the huge number of eggs produced giving rise to overpopulation. Pressure will be on the limited available resources. As a result of this, Intraspecific competition would occur as members of the same fish species would compete for the limited resources.  

Interference and exploitation competition are two types of Intraspecific competition that can reduce the population size of the fish species.

For Interference competition, the dominant and stronger members would secure adequate supply of the limited resources to  detriment of the weaker and less dominant ones. This leads to the death of those members that are weak to compete successfully, thereby leading to a reduction in population size.

In exploitation competition, it involves all individual members of the fish species sharing the limited resources equally, while none of them gets an adequate amount. With time, a great size of the population decrease would be noticed when compared to that of Interference competition.

Finger [1]

Answer:

At the bottom you have the producers aka auto trophic livings (which use inorganic compounds to grow, produce energy, matter and so on..). These organisms would be plants, Cyrano bacteria, over all any organisms that do photosynthesis.

For energy, a plant breaks apart some of the small sugars it builds. What does the plant do with the rest of its small sugars?
balandron [24]

Answer:

The plant stores them as starch

Explanation:

A typical plant synthesizes sugars from photosynthesis by using water and carbon dioxide.

6CO_2 + 6H_20 + energy --> C_6H_1_2O_6 + 6O_2

Parts of the sugar synthesized via photosynthesis is used to generate energy during respiration. The energy generated is useful for other metabolic processes in the plant's body.

C_6H_1_2O_6 + 6O_2 --> 6CO_2 + 6H_20 + energy

<em>The remaining sugar is utilized in the synthesis of starch and stored in the various tissues of the plant.</em>
