Which of the following is a kingdom within the domain Eukarya?

You notice that over the past month, many students on campus have started wearing a new style of school sweatshirt. You think to yourself that perhaps the bookstore has recently started selling this new sweatshirt style. This prediction is an example of

Hypothesis

Which of the following statements regarding a common cellular activity is false?

molecule, organelle, cell, tissue, organ, organ system, organism, population, community, ecosystem

To be scientifically valid, a hypothesis must be

testable and falsifiable.

Kingdom Fungi includes species

that obtain food by decomposing dead organisms and absorbing the nutrients.

An antibiotic kills 99.9% of a bacterial population. You would expect the next generation of bacteria

to be more resistant to that antibiotic.

two experiments are conducted, one differing from the other by only a single variable.
