Answer: d)All of the above
Explanation: Competitive effect is defined as the interaction created between species or organism , which usually results in negative situation. There are certain condition for the competition such as supply of any resource in limited quantity, etc.So competition is also invoked by the density of the species present and in order to exist in an ecosystem and thus there is the high chances of the overlapping of species as well.
Therefore,option(d) is the correct option.
Answer:
It causes no pollution.
Explanation:
The first concern about implementing the method used for coral regeneration is that it causes no water pollution in order to protect the other aquatic animals from the harmful effect of the method used for restoration. If the harmful effect of coral regeneration is higher and disturbing so it must be avoided in order to save other organisms but if there is no harmful effect of the method used for coral regeneration so it must be used.
Can’t see diagram. Could you attach the photo.
Blood typing can identify if will is the father or not by the composition of the genotype and it’s compatibility within the parents.
Will can not be the parent as there is only one possible genotype composition of blood type AB being i^Ai^B.
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.
