Lesson 5: bio 1a cells and homeostasis

#1 which of the following are factors that both unicellular and multicellular organisms actively balance in order to achieve homeosis?

a.) size, shape, and mass

b.) texture, density, and flexibility

c.) wastes, nutrients, and water (correct)

d.) sound, light, and temperature

#2. what would be the outcome of a unicellular organisms that can not maintain homeostasis?

a.) it dies (correct)

b.) it divides

c.) it shrinks

d.) it grows larger

#3 which of the following statements are true?

a.) both unicellular and multicellular organisms are at risk of having too much water entering their cells if they are exposed to water containing no salts (correct)

b.) only multicellular organisms have structures that enable them to regulate excess water entering their cells

c.) unicellular organisms can protect themselves against too much water uptake by closing their membrane channels that allows water transport

d.) unicellular organisms, but not multicellular organism, must deal with the movement of water by osmosis across their cell membranes

#4. how are cells in a multicellular organisms able to achieve homeostasis?

they are uniform in function at work independently from one another

they are specialized in function and work independently from one another

they are uniform in function and work cooperatively with one another

d.) they are specialized in function and work cooperatively with one another (correct)

1.) c
2.) a
3.) a
4.) d

Experiments in environmental toxicology can sometimes be manipulative experiments in which the researcher actively chooses and manipulates the independent variable. in hunt's study, for example, dosages of bpa were manipulated and the effects were measured. in manipulative studies, the researcher controls all the other variables in the experiment, so any health effects observed in the test subjects can be attributed to differences in the independent variable. in other cases, researchers use natural experiments in which the dependent variable (typically a measure of organism health) is measured under differing contexts that are not manipulated. say, for example, that an accidental chemical spill contaminates five ponds. to determine the possible effects of the toxic chemical on frogs, a researcher could compare the hatching rate of frog eggs laid in those five ponds to the hatching rate of eggs laid in five uncontaminated ponds nearby. this would be an example of a natural experiment because concentrations of the toxic chemical in the ponds were not controlled by the experimenter, but rather resulted from the chemical spill. drag type of experiment on the left to the example of experiment on the right. blood concentrations of bpa in college students are compared to their recent manipulative consumption of canned food items 2. the feeding behavior of fish in streams that receive acidic runoff from strip mines is compared to the feeding behavior of fish in unaffected streams. the deformity rate in baby birds from nests in pesticide-sprayed fields is compared to the deformity rate in birds from nests in unsprayed fields 4 tumor development is compared in mice exposed to five dosages of a known carcinogen in the laboratory foraging activity levels are compared in tadpoles exposed to four concentrations of toxic metals in the laboratory. growth of corn plants is compared in field plots sprayed with three different dosage: s of weed killer 7 bpa concentrations in the urine of people with diabetes are compared to bpa concentrations in the urine of people without diabetes - natural; manipulative
