And Composition of the Cell Membrane & Functions
The cell membrane is also called the
membrane and is made of a phospholipid
The
phospholipids have a hydrophilic (water attracting).
two hydrophobic (water repelling).
The head of a
phospholipid is made of an alcohol and
group, while the
tails are chains of
Phospholipids can move
and allow water and other
molecules
to pass through into or out of the cell. This is known as simple
because it does not require
and the
water or molecules are moving
the concentration
gradient. SKETCH AND LABEL a phospholipid coloring the heads red
and the tails blue.
PHOSPHOLIPID

This problem has been solved! see the answeryou are investigating two traits in fruit flies controlled by one gene each. the b gene controls for body color (black or brown), while the r gene controls for body sculpture (rugose or smooth). after crossing rugose black flies with smooth brown flies, you obtain an f1 generation of 100% smooth black flies.what are the dominant alleles? (1 pt)what are the genotypes of the two parent flies to perform a dihybrid test cross? (1 pt)after running a dihybrid test cross, you find 1000 offspring with the following phenotypes: , rugose406black, smooth86brown, rugose94brown, smooth4141000fill in the expected column with the expected number of offspring in each class of phenotypes. (1 pt)what phenotype classes represent the recombinant offspring? (1 pt each)calculate the relative genetic distance between the body color gene and the body sculpting gene (show your work). (1 pt).
