Estimating the Osmolarity of Plant Cells

Estimating the Osmolarity of Plant Cells How can one determine the osmolarity of a potato cell by using different sucrose solutions? Make a prediction for the outcome of a potato core’s mass when placed in a hypertonic solution. Look at the images below. Starting with the potato as #1, number the images in the order […]

Diffusion of Molecules

Diffusion of Molecules Through a Selectively Permeable Membrane Complete the sketch of the experiment design for this experiment DI H20 with dropperfuls of Dialysis bag filled with and added Hypothesis: Hypothesize about the selective permeability of dialysis tubing to glucose. Prediction: Predict the results of the Benedicts test based on your hypothesis (ifthen) What color […]

Darwin’s critical observations

Which of the following was not one of Darwin’s critical observations? Organic evolution is observed at the population level over generations, not at the individual level within generations. 2. A) Certain characteristics can be passed from parents to offspring. B) Most organisms produce more offspring than the c) Traits acquired during the lifetime of an […]

Transposable elements

How can transposable elements promote functional genetic diversity in a population? (2 points) I. Insertion into a regulatory sequence may alter the strength of transcription. II. Insertion into an intro may provide an alternative splice site, producing a protein with a new exon. III. Insertion into an mRNA strand may change the amino acid sequence […]
