The cell membrane is composed of a phospholipid bilayer.

The cell membrane is primarily composed of a mix of proteins and phospholipids

Phospholipids are a major component of cell membranes.  They a head and a tail. The head is hydrophilic  (attracted to water) and the tail is hydrophobic (repelled by water).

They form a bilayer in which their hydrophilic heads face the aqueous cytosol and extracellular fluid  while their hydrophobic tails face away from the cytosol  and extracellular fluid.

The lipid bilayer is semi - permeable

A farmer crossed a yellow maize plant (Yy) with another yellow maize plant (YY). He planted 200 seeds from this cross. How many
Vladimir [108]

Answer: 200 seeds will be yellow.

Explanation: In this crossing, one parent will produce half of its gametes carrying allele Y and the other half carrying allele y. The other parent will have gametes with allele Y. After fecundation, the offspring could phenotype YY or phenotype Yy.

In genetics, Y is related to the dominant allele and y to the recessive one. In this case, having the Y dominant allele determine the color yellow. Therefore, as all of the offspring has the dominant allele Y for yellow, all of the seeds will be yellow, i.e., <u>200 seeds will be yellow</u>.

By the end of anaphase, the 2 halves of the cell have an equivalent collection of chromosomes. In telophase, 2 daughter nuclei form. The nuclear envelope beings to reappear.
