Independent variable: is the UV light exposure
Control group: people not exposed (sample b)
Dependent variable: skin cancer
Experimental group: (sample A)
Answer:
A. Intracellular Thirst
Explanation:
There are two types of thirst and intracellular thirst and extracellular thirst. Extracellular thirst (dehydration) can be ruled out as it only requires water and salt to regenerate blood, at it's correct osmality. On the other hand, intracellular thirst (dehydration) can be corrected by drinking water alone. Therefore, the answer to this problem is intracellular thirst due to thirst for plain water.
The mRNA will attach to the small ribosomal unit and then the large ribosomal unit. Then the mRNA will be decoded with its codon's tRNA. ... The tRNA will come in at the A site and a peptide bond will form between amino acids at the A and P sites.
Answer:
Control group: volunteer stationary bike riders in a pollution-free chamber
Experimental group: volunteer stationary bike riders in a chamber filled with air pollutants common to Los Angeles
Independent variable: exposure to air pollution
Dependent variable: The heart rates (physical fitness) of the volunteer riders.
Explanation:
In a scientific experiment, data is compared between the control group and experimental group to ascertain the effect of the independent variable on the dependent variable. A control group is the group in an experiment that is not treated with the independent variable i.e. the independent variable is controlled while the experimental group is the group that is treated with an independent variable.
N.B: The independent variable is the variable controlled by the experimenter in order to influence the dependent variable (measurable outcome).
In this experiment, the independent variable is the AIR POLLUTION the volunteer riders are exposed to while the dependent variable is the PHYSICAL FITNESS/ HEART RATES of the volunteer riders, which is dependent on the exposure to air pollution (independent variable).
The control group in this experiment is the volunteer riders placed in a POLLUTION-FREE CHAMBER where the independent variable cannot influence or have any effect on the measurable variable (dependent). The experimental group is the volunteer riders placed in a CHAMBER FILLED WITH AIR POLLUTANTS. The independent variable (air pollution) has been changed in the experimental group.
Answer:
Opportunistic.
Explanation:
Pathogen may be defined as the disease causing organism. The opportunistic pathogen causes disease mostly in the organism with weak immune system of the body.
The opportunistic pathogen can cause disease if the environmental condition is favorable for pathogen. These pathogens are not capable of inducing disease in the healthy individual.
Thus, the answer is opportunistic.
