3) beaker A was the controlling variable
Answer:
Why is the air colder farther from the earth,you ask ?its easy
Explanation:
A pretty basic answer is that the farther away you get from the earth, the thinner and thinner the atmosphere gets. The total heat content of a system is directly related to the amount of matter present, so it gets cooler and cooler at higher elevations.
the Pacific, Atlantic, Indian, Southern, and Arctic.
I hope this helps please mark me as brainliest;)
The enzyme Taq polymerase is required in the PCR process because it is the main enzyme that synthesizes the new DNA strands complementary to the template strand and without the activity of this enzyme the PCR will be useless and it cannot make the copy of the given strand in any way. Thus, this enzyme is very much necessary for the efficient working of the PCR.
Polymerase Chain Reaction is a very efficient technique that can able to detect and copy even a small amount of DNA by performing a set of reactions at different temperatures.
The PCR process begins with the denaturing of the template strand at 95°C, followed by annealing in which the appropriate primers bind to the single strands of DNA at 50-56°C, followed by extension at 72°C in which the thermostable Taq polymerase synthesizes the strand complementary to the template DNA.

The statements that are true concerning living organisms and how they acquire energy are;
Cells, the basic unit of life, cannot survive on their own. Instead, all living organisms must obtain and use energy to live.
The daily food consumption of an organism provides the energy to support all the metabolic processes required for the organism to live.
What are Living organisms?
Living organisms can be regarded as organisms that possess characteristics such as the ability to move and reproduce.
However, they acquire useful energy in different ways, and the daily food consumption of an organism provides the energy to support all the metabolic processes.
