Answer:
two, phospholipids, non polar, tails, polar, heads.
Explanation:
This is just basically illustrating one of the components of the lipid bilayer memebrane. The membrane is made up of two lipid layers with the polar head groups facing either the cytosol or the outer surroundings while the non polar tails facing each other. Such that this bilayer act as a barrier between the cytosol of the cell/organelle eg endoplasmic reticulum and the outer surroundings.
Very true. There are several phyla
A genetic outcome of a genetic cross between the same parents is independent of previous outcomes.
<h3>What is genetic variation?</h3>
Genetic variation can be defined as the genetic poll of an organism, which is the raw material trough which evolution can occur by natural selection.
During sexual reproduction, the formation of gametes generates different genetic backgrounds which are independent of distinct gametes.
In conclusion, each genetic outcome of a genetic cross between the same parents is independent of all previous outcomes.

All of the above- 1, 2, and 3 These introduce variation into the chromosome or into the zygote and create cells and offspring unique from the parents.
