The appropriate answer is c. a scientific journal. A scientific journal is a collection of papers based on topics in science that have been written by experts in their fields. Individuals with a masters or doctorate in various subject areas are published here.

From the list given this is the best second source for the research. Science fiction novels and not real and so would be unacceptable. Magazines and news papers reporting on scientific research most likely get information from scientific journals.

Which reaction best explains why carbon is able to from macromolecules ?
guajiro [1.7K]

Answer:

Carbon can bond with many elements

Explanation:

Carbon can bond with many elements, including itself, to form macromolecules. Moreover, it can form four bonds, and that makes possible many different arrangements of the atoms in the molecules.

D is <em>wrong</em>. Carbon can bond with many other elements beside itself.

diamong [38]

To test his hypothesis, the student will have to design an experiment to measure the effects of <u>temperature on cellular growth</u>.

To test the effects of temperature on cellular growth the student will have to create an experiment containing the there kinds of variables:

  • Dependent
  • Independent
  • Control

In this experiment, the control variable will be the kind of cells used, as well as the incubation methods being used. We identify these as the control variable given that they will remain constant.

The independent variable will be the Temperature at which we will place each cell being studied. The dependent variable, on the other hand, is by definition, what we seek to measure. In the case given it would correspond to the amount of cellular growth.

To test his theory of the effects of temperature on cellular growth, a student can design an experiment in which the control variable will be the cells themselves, the independent variable will be the Temperature, and the cellular growth can act as the dependent variable.
