The correct answer is D. Xenobiotics
Explanation:
In biology, the word "xenobiotics" refers to any substance or chemical compound that is considered as not natural or synthetic is an organism, this means the substance or compound is not produced by the organism and therefore it is not expected to be found on it. In the seam way, a substance that is natural to the organism but that is found in abnormal concentration might be considered as a xenobiotics. This concept differs from pesticides because these are substances used to control pests and from bio remediators because these are used to deal with contamination. Therefore, the word that describes synthetic compounds that are not produced or expected to be present in an organism is xenobiotics.
Answer:
This question is asking to identify the variable in the experimental statement.
The eye chart is the CONTROL VARIABLE
Explanation:
An experiment consists of several variables to look out for in order to achieve any significant result. These variables are independent variables, dependent variables and control variables. Although independent and dependent variables are the major experimental variables, but control variables are also important.
A control variable is the variable that remains constant or unchanged throughout the experiment. Any change to the control variable will affect the dependent and independent variables. In this question, the eye chart is the CONTROL VARIABLE because it remains constant or unchanged. The same eye chart is used for the experiment.
N.B: The distance to the eye chart is the independent variable while the number of letters visible on the line is the dependent variable. Hence, changing the eye chart (control variable) will affect the distance and the number of letters visible.
The substrate and the active site both need to fit together perfectly in order for the enzyme to work properly. If their shape is changed, typically through heat or a change in pH, the enzyme will not work.
Parietal lobe and frontal lobe
If you want to prevent yourself from being bias you must not base anything off of your opinion, or what you think is the right answer.
Everything must be strictly facts with no intention of trying to persuade the reader. If you truly believe that you need something in your paper, make sure you can support your claim with actual facts (it is very important that you back up all of your claims with actual facts)
Refrain from using things like:
•In my opinion
•I think
•I believe
•I know
•Everyone knows that
