Answer:
The correct answer is -
the independent variable - if fertilizer added or not,
the dependant variable - the height of the plant and
the standardized variable - 200ml water
Explanation:
In this study, the student wanted to see the effect of the fertilizer on the growth of the plant so the independent variable is the treatment of the fertilizer as manipulated or the independent variable is the factor which is affected or changed purposely during an experiment while other variables remain constant.
The dependent variable is the factor that is based or depends on the independent variable and measured to see the effect which is the height of the plants in this case.
The standardized or the control variable is the variable that remains constant throughout the experiment, 200 ml water treatment is the control variable in this experiment.
Answer:
Explanation:
A scientific researcher performs scientific methods to answer any natural process. The researcher will follow the protocol of a scientific method which includes: observe the natural phenomenon, ask related questions, suggest a hypothesis, perform the experiment and suggest answers.
In the given question if the researcher has to study about the flu virus, the possible questions he would ask will be:
1. The life cycle of the flu virus.
2. Effect of the virus on the life of an organism.
3. The mechanism used by the virus to replicate and to infect any organism.
4. Molecular mechanism of a virus.
The action that will directly affect the gravitational force between two objects is increasing the pressure on the objects (option B).
<h3>What is gravitational force?</h3>
Gravitational force is a very long-range, but relatively weak fundamental force of attraction that acts between all particles that have mass; believed to be mediated by gravitons.
Gravitational force can also be referred to as the force due to gravity of a planet.
The gravitational force between two objects can be affected by the following factors:
- Increase in pressure
- Increase in temperature
- Increase in speed of objects
Therefore, the action that will directly affect the gravitational force between two objects is increasing the pressure on the objects.

In this situation, you should direct your partner to manually stabilize the women's head, while you quickly visualize her chest to search for signs of breathing. I hope that this helps you!
Answer:
The organelles in an animal cell are as follows:
cell membrane, nucleus, nucleolus, nuclear membrane, cytosol, smooth endoplasmic reticulum, rough endoplasmic reticulum, Golgi apparatus, ribosomes, mitochondria, centrosome, cytoskeleton, vacuoles, vesicles, and lysosomes.
Explanation:
An animal cell is a typical example of an eukaryotic cell i.e a cell that contains a membrane-bound nucleus. In the cell are certain structures that performs specific functions in the cell called ORGANELLES. The organelles, according to this question, are found suspended or cushioned in the cytoplasm of the animal cell.
A list of the organelles in the cytoplasm (part of the cell that excludes the nucleus) of an animal cell are as follows:
- cell membrane
- nucleus
- nucleolus
- nuclear membrane
- cytosol
- smooth endoplasmic reticulum
- rough endoplasmic reticulum
- Golgi apparatus
- ribosomes
- mitochondria
- centrosome
- cytoskeleton
- vacuoles
- vesicles
- lysosomes
