only in a controlled experiment... * 1 point
will the groups you compare vary in multiple unpredictable ways.
will you inform a particular hypothesis.
a single factor (variable) is changed among groups.
will researchers observe the factor (variable) in a natural setting.
can specific predictions be made about an outcome.

which of the following properties or processes is not * 1 point associated with living things?
evolving populations
maintenance of internal environment

consist of cells
genetic information stored in protein

to find out if the herbicide atrazine may cause testicular abnormalities in male frogs, the hayes lab collected frog and water samples from eight widely separated agricultural sites across the u.s. and quantified the correlated incidence of reproductive abnormalities with environmental atrazine concentrations. this was a(n) ______ experiment.
comparative
controlled
inductive
logical
deductive

starch and glycogen are similar in that both of them * 1 point
are polymers of gluc
contain ribose

Explanation:

1. A simple sugar with the formula C5H10O5 has 5 carbon atoms. Pentoses are sugars with 5 - carbon atoms. Hexoses have 6 - carbon atoms, polysaccharides are long - chain carbohydrates made of many monosaccharides, disaccharides are made of two monosaccharides, and lipids are a different class of biomolecules.
2. In a controlled experiment, only one factor (variable) is changed among groups to isolate the effect of that variable.
3. Genetic information is stored in nucleic acids (DNA and RNA), not in proteins. Evolving populations, maintenance of internal environment, extracting energy from the environment, and consisting of cells are all properties of living things.
4. The Hayes Lab collected samples from different natural sites and correlated two variables (reproductive abnormalities and atrazine concentrations). This is a comparative experiment as it compares different natural settings without strict control over all variables as in a controlled experiment.
5. Starch and glycogen are both polymers of glucose. Ribose is a 5 - carbon sugar found in RNA and is not a component of starch and glycogen.

Answer:

1. pentose
2. a single factor (variable) is changed among groups
3. genetic information stored in protein
4. comparative
5. are polymers of glucose
