A student compared 2 plants at varying humidity levels. Which would prevent error?

Both groups planted in same soil type

Which would most likely result in a change to the current classification of an organism?

Linking the organism to different ancestors by DNA

Which statement is an inference based on this information?

Milkweed seeds are dispersed by wind.

Students conclude that light causes water evaporation, causing vapor. Alternate explanation?

light caused elodea to photosynthesize releasing O2 gas

Which conclusion did the biologist most likely make from the data shown?

Optimum habitat for the warbler is 100 juniper trees.

Darwin's explanation for evolution was dependent on which scientific concept?

The existence of variations in a population.

Which statement best describes her hypothesis?

She thinks that some robins must migrate in the winter.

For the growth curve to continue increasing, which of these must occur?

Resources in the environment must be unlimited.

Structural differences between tadpole and an adult frog are due to

different genes expressed at each stage of development

In an ecosystem, a sudden decrease of soil bacteria would likely result in -

reduction of nitrogen available in ecosystem

Answers

1
Jackrabbit's increases blood circulation to the ears when its hot, and decreases at night/cold.
This is caused by homeostasis
This is caused by excretion
This is caused by detoxification
This is caused by osmosis
2
A student compared 2 plants at varying humidity levels. Which would prevent error?
Both groups planted in same soil type
One type of plant should have been tested
Percentage of humidity should be constant
Fewer plants in each group
3
A dissolved oxygen probe is used in a lab using samples of pond water. The probe's function is
to create a model
is to gather accurate data
to analyze investigation conditions
is to test a hypothesis
4
Which would most likely result in a change to the current classification of an organism?
Observing organisms that occupy the same ecological niche
Finding a related organism that was considered extinct
Linking the organism to different ancestors by DNA
Discovering organisms w/ similar physical traits in fossils
5
Which statement is an inference based on this information?

9
Students conclude that light causes water evaporation, causing vapor. Alternate explanation?
Gravity increased downward water flow of trapped air
Heat from the light caused escape of dissolved gas
Metabolism of elodea absorbed CO2 from water
