“Proficiency in scientific reasoning would free individuals from the dominance of authoritarian teaching and empower them to derive truth independently.”

Viewing the World with Microscopic Vision
Sunspots viewed from a telescope and binoculars
Look at an Entire Process, … Sequence of Steps … or a Procedure
A comically involved, complicated invention, laboriously contrived to perform a simple operation.
(1) natural selection
(2) asexual reproduction
(3) genetic engineering
(4) habitat modification
As you walk past cobbler shop, hook (A) strikes suspended boot (B), causing it to kick football (C) through goal posts (D). Football drops into basket (E) and string (F) tilts sprinkling can, (G) causing water to soak coat tails (H). As coat shrinks, cord (I) opens door (J) of cage, allowing bird (K) to walk out on perch (L) and grab worm (M) which is attached to string (N). This pulls down window shade (O) on which is written, "YOU SAP, MAIL THAT LETTER." A simple way to avoid all this trouble is to marry a wife who can't write.
How Well Can You Draw It?
The sequence of events occurring in the life cycle of a bacterium is listed below.
(A) The bacterium copies its single chromosome.
(B) The copies of the chromosome attach to the cell membrane of the bacterium.
(C) As the cell grows, the two copies of the chromosome separate.
(D) The cell is separated by a wall into equal halves.
(E) Each new cell has one copy of the chromosome.
This sequence most closely resembles the process of
(1) recombination (2) zygote formation
(3) mitotic cell division (4) meiotic cell division
Using the Step-By-Step Template
Is this the only answer?
Describe the four steps of producing recombinant DNA in bacterial cells.
Steps Left Out Lead to Questions … or Confusion
An experiment was carried out to determine which mouthwash was most effective against bacteria commonly found in the mouth. Four paper discs were each dipped into a different brand of mouthwash. The discs were then placed onto the surface of a culture plate that contained food, moisture, and bacteria commonly found in the mouth. The diagram below shows the growth of bacteria on the plate after 24 hours. Which change in procedure would have improved the experiment?
The laboratory setups represented below were used to investigate the effect of temperature on cellular respiration in yeast (a single celled organism). Each of two flasks containing equal amounts of a yeast-glucose solution was submerged in a water bath, one kept at 20° C and one kept at 35°C. The number of gas bubbles released from the glass tube in each setup was observed and the results were recorded every 5 minutes for a period of 25 minutes. The data are summarized in the table below. (Graphed from Data Table)
An experiment was carried out to determine how competition for living space affects plant height. Different numbers of plants were grown in three pots, A, B, and C. All three pots were the same size.
Analyze the experiment that produced the data shown in the table. In your answer be sure to:
The diagram below represents events associated with a biochemical process that occurs in some organisms. Which statement concerning this process is correct?
A student fills a dialysis membrane bag with a mixture of red dye, yellow dye, and water. He soaks the bag in pure water for 24 hours and then observes that the water outside the bag turns yellow. Which statement best explains the results of this experiment?
In order to produce the first white marigold flower, growers began with the lightest these plants produced seeds, which were planted, and only the offspring with very light yellow flowers were used to produce the next generation. Repeating this process over many years, growers finally produced a marigold flower that is considered the first white variety of its species.
This procedure is known as
(1) differentiation (3) gene insertion
(2) cloning (4) selective breeding
Reorganizing Information: Variations in Darwin’s Finches red dye, yellow dye, and water. He soaks the bag in pure water for 24 hours and then observes that the water outside the bag turns yellow. Which statement best explains the results of this experiment?
Create a Dichotomous Key (using the DK Template) for the:
- 1. Warbler Finch
- 2. Woodpecker Finch
- 3. Vegetarian Finch
- 4. Large Ground Finch
– (Wood, Vegetarian, Large Ground)
– (Wood, Vegetarian)
