Answer:
The hydrophobic tails of the phospholipids
Explanation:
Because the phospholipid bilayer is made up of a hydrophillic head and a hydrophobic tail, the phospholipids spontaneously form a bilayer in water. This is because the hydrophobic tails are repelled by the water, meaning they retreat into one another, whereas the phosphilipid heads are attracted to water. This means the heads form the outside of the layer, and the tails form the inside of the layer.
DNA is contained in blood, semen, skin cells, tissue, organs, muscle, brain cells, bone, teeth, hair, saliva, mucus, perspiration, fingernails, urine, feces, etc. Where can DNA evidence be found at a crime scene? DNA evidence can be collected from virtually anywhere.
Answer:
Fossils are important evidence for evolution because they show that life on earth was once different from life found on earth today. Paleontologists can determine the age of fossils using methods like radiometric dating and categorize them to determine the evolutionary relationships between organisms.

More widely available food chain for other predators, an increase in population of the prey.
Answer and Explanation:
Principal of Spiral plating:In the spiral plate technique, a mechanical plater vaccinates the fluid sample on a pivoting plate agar. The volume of fluid sample decline from the inside to the edge of the plate. The microbial concentration is controlled by checking the provinces on a piece of the Petri dish.
A technique, portrayed for deciding the quantity of microorganisms in an solution by the utilization of a machine which stores a known volume of test on a pivoting agar plate in a consistently diminishing sum as an Archimedes spiral.
Materials used: agar plates, dilution blanks, pipettes
Method:
A spiral plater is a gadget that disperses a constantly diminishing volume of fluid over a solitary pivoting agar plate (the apportioning arm moves like a needle on a turntable, just in reverse). The agar is then hatched and checks are made. It can viably convey up to a 105 concentration range on one plate, yet list requires an uncommon tallying lattice. After the example is brooded, distinctive state densities are clear on the outside of the plate. A changed checking matrix is portrayed which relates zone of the plate of volume of test. By checking a proper territory of the plate, the quantity of microscopic organisms in the example is assessed.
