The growth of the plants is the dependent variable in this experiment on tomato plants' growth. The amount of sunlight, water, and fertilizer are independent variables that were controlled and varied to observe their impact on plant growth.
The dependent variable in this experiment is the growth of the plants. The independent variables are the amount of sunlight, amount of water, and amount of fertilizer. By keeping the amount of sunlight and water constant, and varying the amount of fertilizer, the student can determine the effect of fertilizer on plant growth.
Answer:
disruptive/diversifying selection
Explanation:
Disruptive (also known as diversifying) selection is a type of natural selection where extreme phenotypic values are more favored rather than intermediate phenotypes. The disruptive selection favors the survivance and reproduction of organisms with extreme phenotypic traits, and in turn impairs the reproduction of organisms with intermediate traits, thereby changing the allele frequencies in the population in order to favor extreme values. An example of disruptive selection is the beak size of Galapagos finches, where extreme phenotypes of this trait have shown to be adaptive according to the type of food found in each island.
Answer:
In chemistry, solvent effects are the influence of a solvent on chemical reactivity or molecular associations. Solvents can have an effect on solubility, stability and reaction rates and choosing the appropriate solvent allows for thermodynamic and kinetic control over a chemical reaction.

The correct answer is option C.
Explanation:
The human gastrointestinal microbiota or the gut microbiota or the gut flora refers to the microbes, which thrive in the digestive tracts of humans. The human gastrointestinal tract comprises the gathering of all the genomes of gut microbiota. It is the niche where the human microbiota is found.
The microbial composition of the gut microbiota differs across the digestive tract. In the small intestine and stomach, very small species of bacteria are found, while the colon comprises the densely populated microbial ecosystem. Of these over 99 percent of the bacteria found in the gut are anaerobes, as the space within the intestines is highly anaerobic.
These microbes are confined deep within the body where oxygen cannot reach as it is not supplied with the help of blood vessels. Thus, a highly anaerobic environment is witnessed deep within the intestinal regions.
Cell contains hereditary information that is passed from cell to cell during cell division.
Living cells can be created from dead cells.
All cells perform similar metabolic activities
The statement which were not in the original cell theory, but are further explained by the modern cell theory include the following below:
B. Cell contains hereditary information that is passed from cell to cell during cell division.
D. All cells perform similar metabolic activities.
This is referred to as the simplest unit of life and it undergoes aggregation to form tissues which perform similar functions.
In the original cell theory, it was said that cells are similar in structure and function but the aforementioned above options had to be further explained by the modern cell theory.
