Answer:
c. Independent = Fertilizer amount, Dependent = Yield
Explanation:
In an experiment, the independent variable is changed to observe its effect on the dependent variable. In the given experiment, the potted tomato plants were treated with different amounts of fertilizer to observe the effect of the amount of fertilizer on the plant yield. Therefore, the amount of fertilizer is an independent variable here. Since the effect of change in the amount of fertilizer was observed in terms of plant yield, the "plant yield" is a dependent variable in the experiment.
Answer:
Independent Variable - Soil, Dependent Variable - Height, Control Variable - Sun and Water
Explanation:
First we should define what the variables in the experiment are.
Independent variable is the aspect of the experiment that has a different value for each subject in order to find out how it affects the dependent variables.
Dependent variable is the variable that is kept under observation and recorded by the experimenters in order to track the changes and define its relationship with the other variables/parameters.
Control variable is the variable that is kept constant intentionally by the experimenters to be able to define the relationship between the other variables more clearly and easily.
In the example given in the question, there are one of each variable mentioned above which are, according to the definitions;
- Independent Variable - The Soil
- Dependent Variable - The Height Of The Plant
- Control Variable - The Amount of Water and Sun Exposure
I hope this answer helps.
Answer:
This question lacks options, options are:
A.Carrying capacity will increase B.Carrying capacity will decrease C.Carrying capacity will remain unchanged. The correct answer is B.
Explanation:
Ecologists define 'carrying capacity' as the population of a certain species that a defined habitat can support indefinitely, without permanently damaging the ecosystem on which they are dependent,that is, the ecological carrying capacity of an ecosystem is the maximum growth limit of a biological population that the environment can support in a given period, without negative effects on that population or on the environment.
There are a few differences between animal cells and plant cells.
Plant cells have cell walls, and animal cells do not.
Plant cells have a large central vacuole and animal cells do not.
But probably the most recognizable (and probably the one your question is asking about) is the chloroplast. The Chloroplast is the home of chlorophyl, a green pigment plants use to make energy.
Answer:
The right answer is Option A. It filters the blood that is used by the excretory system.
Explanation:
The endocrine system has great affect on the excretory system. It gives massages to the excretory system. When the amount of water is exceed in the body, the endocrine system send massage to the excretory system to produce more urine. And when the body has less amount of water, the
endocrine system send massage to the excretory system to produce less urine.
