Answer:
What was the answer
Explanation:
Was the answer A or D?
The variables are the factors, which do not have a fixed value. Their value keeps changing in an experiment. It can be divided in two types: dependent variable and independent variable.
The dependent variable in the experiment is the variable, whose tendency to vary depend on other factors. To test this hypothesis, the rate of photosynthesis with respect to different wavelengths. So, the dependent variable is rate of photosynthesis, as it is dependent on the wavelength of the light.
B. gravitational, weak nuclear, electromagnetism, strong nuclear.
C. strong nuclear, electromagnetism, gravitational, weak nuclear
D. weak nuclear, gravitational, strong nuclear, electromagnetism
Tissues is just below organs in complexity.
A tissue is a collection of cells and extracellular matrix from the same origin that work together to perform a defined function. Multiple tissues are then functionally grouped together to form organs.
The hierarchy is the following (from the most simple to most complex):
1. Cell
2. Tissue
3. Organ
4. Organ system
5. Organism
