Draw it an artificial "cell" consisting of an aqueous solution enclosed in a selectively permeable membrane is immersed in a beaker containing a different solution, the "environment," as shown below. the membrane is permeable to water and to the simple sugars glucose and fructose but impermeable to the disaccharide sucrose.

a. draw solid arrows to indicate the net movement of solutes into and/or out of the cell.

b. is the solution outside the cell isotonic, hypotonic, or hypertonic?

c. draw a dashed arrow to show the net osmosis, if any.

d. will the artificial cell become more flaccid, more turgid, or stay the same?

e. eventually, will the two solutions have the same or different solute concentrations?

Which of the following occurs after a natural or unnatural disturbance in an ecosystem

Bisphenol a (often called bpa) is a chemical found in products that people use every day, from water bottles to food containers to children's toys. unfortunately, bpa leaches out of its many products and makes its way into our bodies. what are the health effects of bpa exposure? ongoing research is finding that elevated exposure to bpa can affect a wide variety of developmental and physiological processes, but one of the first studies of bpa's health effects came about because of a simple mistake in the lab. at a laboratory at case western reserve university in 1998, geneticist patricia hunt was making a routine check of her female lab mice. as she extracted and examined developing eggs from the ovaries, she began to wonder what had gone wrong. she noticed that many of the eggs showed problems with their chromosomes, and some had irregular amounts of genetic material, which can lead to miscarriages and birth defects in mammals. she learned that a lab assistant had mistakenly washed the plastic mouse cages and water bottles with a harsh soap, releasing bpa from the plastic. knowing that bpa is an endocrine disruptor, a chemical that can enter organisms and mimic hormones, hunt set out to discover whether it had adversely affected her mice.
