To test the effect of vitamin D on growth, two groups of rats were raised under identical
conditions and fed the same diet. One of the groups received daily injections of vitamin D. The
other group received injections of saline, which did not contain vitamin D. All the rats were
weighed weekly for 2 months. In this experiment, what was the control?
(A) group receiving vitamin D
(B) group receiving saline
(C) average weight gain of the rats
(D) 2-month period of time
(E) NONE of the above B- group receiving saline
A good experiment should include as many variables as possible at the same time. True or
False? False
Photosynthetic bacteria are examples of autotrophs. True or False? True
The variation among individuals, on which natural selection acts, is?
(A) physical training and excerise
(B) random occurrences in the lifetimes of individuals
(C) Genetic differences
(D) nutritional differences
(E) NONE of the above C- Genetic differences
Why do heterotrophs require "food" for survival?
(A) Food is an alternative source of energy for hetertrophs when sunlight is unavailable
, (B) Food provides the organic chemicals needed by heterotrophs
(C) Food provides at least half of the water required by heterotrophs
(D) Heterotrophs cannot photsynthesize without the chemicals provided by food
(E) NONE B-Food provides the organic chemicals needed by heterotrophs
Science cannot answer certain moral questions because?
