4. The common grackle is a species of robin-sized blackbirds that are fairly common (hence the name) over
most of the United States. Suppose that long tails (T) were dominant to short tails in these birds. A female
short-tailed grackle mates with a male long-tailed grackle that had one parent with a long tail and one parent
with a short tail. Using a Punnett Square, answer the following questions.
Parental Cross:
Female Eggs
What is the male's genotype?
How many of each genotype will be found in the F, generation (assume 4 offspring)?

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.
