hydrophillic head, hydrophobic tail, hydrophobic tail, hydrophillic head

Answer:

The correct order would be a hydrophilic head, hydrophobic tail, hydrophobic tail, and hydrophilic head.

The plasma membrane is a lipid bilayer, that is, a layer formed of two layers of phospholipids.

A phospholipid is made up of two parts; hydrophilic polar heads and hydrophobic lipid tail.

The two layers are arranged in such a way that the hydrophilic parts are present outwards and the hydrophobic tails are sandwiched between the polar heads of two layers.  

Thus, the order would be a hydrophilic head, hydrophobic tail, hydrophobic tail, and hydrophilic head.

Living things come from other living things through either sexual or asexual reproduction.
Iteru [2.4K]

Explanation:

Organisms don’t have to only reproduce sexually or only reproduce asexually - some animals do both!

When conditions are good, such organisms will reproduce asexually because it is easier. For example, starfish (by fragmentation), slime molds, and water fleas/daphnia (by parthenogenesis) all reproduce asexually when there is plenty of food, minimal predators, and not too much crowding of individuals of the same species.

When conditions worsen (less food, too many individuals, etc), they may switch to sexual reproduction in order to add genetic variation to their population and ensure survival through difficult times.

The genes for miniature wings (m) and garnet eyes (g) are approximately 8 map units apart on chromosome 1 in Drosophila. Phenoty
Anestetic [448]

The following phenotypic classes reflect offspring that were generated as a result of a crossover event

  • wild type
  • miniature wings
  • garnet eyes

Explanation:

When the miniature wings and garnet eyes links up with the 8 map unit that are present between them. After that the presence of two recombinant classes must complement together and make 8% of total i.e. they contribute 4% each. together the parental classes make up to 92% by contributing 46% one.

This can be understood through a phenotypic ratio calculation, which can be expected from it.

wild type: 4% x 800 = 32

miniature wings: 46% x 800 = 368

garnet eyes: 46% x 800 = 368

miniature wings, garnet eyes: 4% x 800 = 368
