Answer:
Cell theory refers to the idea that cells are the basic unit of structure in every living thing. Development of this theory during the mid 17th century was made possible by advances in microscopy. This theory is one of the foundations of biology.
Answer:
osmosis is the movement of a solvent across a membrane, so water
Answer:
f = m - u
Explanation:
DNA methylation is an important epigenetic modification associated with the regulation of gene expression. As such, the analysis of DNA methylation marks and the dynamics of this process may shed light on the genes that are being expressed at a given time in a given cell type/tissue. In the example above described, f is defined as the fraction of the DNA molecule that is methylated after one (1) hour, whose value can be estimated by subtracting u fraction (i.e., fraction of methylated locations that become unmethylated) from m fraction (i.e., fraction of unmethylated locations that become methylated).
In consequence, the equation is
f = m - u
concise verbal or mathematical statement of a relation that expresses a fundamental principle of science, like Newton's law of universal gravitation.
The correct answer is 4) A dichotomous key is complete when each organism stands alone.
The statement about a dichotomous key that is true is "A dichotomous key is complete when each organism stands alone."
Scientists have the need to correctly identify organisms, animals, plants, and objects. For that to happen, they have dichotomous keys.
These tools help them to identify and give a correct name that differentiates from other objects and organisms. So the most important thing about the dichotomous key is the fact that it identifies an organism, species or objects with its scientific name.
