Answer:
Independent variable: type of instrument
Dependent variable: Number of rabbits attracted
Experimental group: The group when he played an instrument
Control group: The group when not playing an instrument
Constant: Same song
Explanation:
1. Independent variable is the variable that the experimenter changes or manipulates in an experiment. In this experiment, the variable that is changed is the TYPE OF INSTRUMENT used (clarinet, flute, guitar), hence, it is the independent variable.
2. Dependent variable is the variable that is measured in an experiment. It is the variable that responds to the changes made to the independent variable. In this experiment, the dependent variable is the "NUMBER OF RABBITS ATTRACTED" by the instrument played.
3. Experimental group is the group of an experiment that receives experiment treatment, which is the independent variable. In this case, the experimental group is the GROUP IN WHICH INSTRUMENT WAS PLAYED.
4. Control group is the group that does not receive the experimental treatment. In this case, the control group is the group in which INSTRUMENT WAS NOT PLAYED.
5. Constants are those variables that remains unchanged for all groups throughout the experiment. In this case, one constant is the SAME SONG played.
Answer:
i dont know right now bc im :lExplanation:
Answer:
33.3 cM
Explanation:
Parent 1: blue shell, long antenna : BBLL
Parent 2: green shell, short antenna : bbll
BBLL X bbll :
F1 : BbLl ( blue shell, long antenna )
BbLl X bbll :
BL/bl = 82 : Parental
bl/bl = 78 : Parental
Bl/bl = 37 : Recombinant
bL/bl = 43 : Recombinant
Total = 240
Recombination frequency = (Number of recombinants/ Total offspring)*100
= (80/240) * 100 = 33.33 %
Map distance = recombination frequency
Hence, map distance = 33.3 cM
Answer:
b. smoking can paralyze the ciliary escalator.
Explanation
Generally cilia in the respiratory tract of smoker will undergo paralysis for 1-3 hours after smoking, and generally paralyzed in chronic smokers.
This is because the toxins( the TAR) in the cigarette destroy the mucocilliary escalator that trapped inhaled pathogens in air as it passes through the bronchi and push them up with phlegm out of the respiratory tract.
Therefore ,with the loss of cilirary function, pathogens are retained in the lungs leading to respiratory tract infections
