Answer:
Independent: Purposely altered
Dependent: Changes with respect to the independent being altered
Controlled: Never changes
Explanation:
An independent variable is a variable in which does not rely on other pieces/variables of an experiment to assume a value. In other words, it does not change when other variables change. However, it can be changed intentionally by the scientist.
A dependent variable is a variable in which its change in value relies on other pieces/variables of an experiment to assume a value. So, if the indeoendent variable is changed, the dependent variable will change as well. The opposite is not true though - if the dependent variable changes (for whatever reason), the independent variable hasn't necessarily been changed.
A controlled variable is a variable that stays CONSTANT throughout an experiment. It is never changed, and nothing will change it. An example of a control variable is the number of participants in a study: no more participants are being added, and no participants are being removed. The number of participants remains STATIC throughout the study.
(Both remove urea from the body) is the answer.
Because for the urinary system, it removes urea and waste through the body through urine. For the skin, it removes urea through sweat. Both are secretions that help rid the body of waste.
Explanation:
Sweat glands in the skin discharge a fluid waste called sweat or exudation; however, its primary functions are heat control and pheromone release. The purpose of the urinary system is to discharge waste from the body, control blood volume and blood pressure, control levels of electrolytes and metabolites, and regulate blood pH.both eliminate excess waste from the body.
Answer:
The endomembrane systemis a group of membranes and organelles in eukaryotic cells that works together to modify, package, and transport lipids and proteins.
Answer;
The above statement is false.
Explanation;
-CNS nerve fibers do not regenerate because of the actions of Schwann cells.
-PNS nerve fibers regenerate because of the actions of Schwann cells, but Not CNS nerve fibers.
-Nerve Fibers are slender processes of neurons, including the axons and their glial envelopes (myelin sheath). They conduct nerve impulses to and from the central nervous system.
