<span>The variables in this study would be the folic acid used (the independent variable) and the DNA formed through the implementation (the dependent variable). By changing the amount of folic acid used in the experiment, the DNA will possibly be changed in the microbes.</span>
His body will react as if he is being starved, this causing his basal metabolic rate to drop.
Answer:
A. All of these choices are correct.
Explanation:
In pharmacology , drugs play different roles from simple to complex.
as is the above mentioned question drugs can facilitate the transmission of information from one neuron to another so option B is correct.
While the drugs / chemicals can inhibit the transmission of information from neuron to another so option C is also correct.
And the drugs can also be used to cure a whole variety of clinical disorders by playing a role at the synaptic level.
Hence option A All of these choices are correct is the right answer.
The correct answer is A. Experimental group
Explanation:
In experiments, the experimental group refers to the group of subjects that receives special treatment or in which the scientist or researcher intervenes. This is the opposite of a control group that does not receive treatment and therefore, it is used as a reference to measure the effect of the treatment.
This implies, in the experiment presented Group A is the control group as they do not have special treatment because they sleep normally and Group B is the experimental group as the researcher modifies their sleep time and reduces it two hours which means in this group there is a treatment or intervention.
Answer:
The correct answer is principle of superimposition.
Explanation:
According to the superimposition principle, in the undisturbed rocks, the youngest rocks are situated on the top and the oldest rocks are found in the bottom. The phenomenon takes place due to withering. The rocks get withered because of the influence of air and water.
The soil particles or the sediments get gathered at another site. The deposits of sediments get concentrated with time and result in the production of rocks. The mature rocks get surrounded by the layers of sediments with time passing by. These sediments get concentrated again to produce novel rocks. Through this procedure, the fresh young rocks get produced over the older ones.
