A student formed the hypothesis "If corn seeds were planted in freezing temperatures, then they would not germinate (grow)". 20 grains of corn were
planted on moist filter paper in each 2 petri dishes. The dishes were covered with
black paper to exclude light. Dish #1 was kept at 0 C (freezing) and dish #2 at 25
C. After 10 days, no seeds in dish #1 had germinated: 18 seeds in dish #2 had
germinated by the end of the fifth day.
Dish #2 in the experiment above represented the
the control group
the variable
the experimental group
the hypothesis

The kidneys, ureter, bladder, and urethra the body maintain homeostasis through the process of a. excretion b. specialization c. respiration d. digestion

Which statements about the fluid mosaic structure of a membrane are correct? select the three correct statements.which statements about the fluid mosaic structure of a membrane are correct? select the three correct statements.the framework of a membrane is a bilayer of phospholipids with their hydrophilic heads facing the aqueous environment inside and outside of the cell and their hydrophobic tails clustered in the center.because membranes are fluid, membrane proteins and phospholipids can drift about in the membrane.the diverse proteins found in and attached to membranes perform many important functions.the kinky tails of some proteins keep the membrane fluid by preventing the component molecules from packing solidly together.membranes include a mosaic, or mix, of carbohydrates embedded in a phospholipid bilayer.
