In 1895, Ernest Overton proposed that cell membranes were made of lipids

According to the lipid bilayer theory, which Gorter and Grendel put forth in 1925, the cell membrane bilayer structure can be described using crystallographic research and observations of soap bubbles.

<h3>What is Cell membrane ?</h3>

All cells have a cell membrane, also known as a plasma membrane, which separates the interior of the cell from the external environment.

  • A semipermeable lipid bilayer makes up the cell membrane. The movement of materials into and out of the cell is controlled by the cell membrane.
  • Biological membranes serve three main purposes. First, they prevent harmful substances from entering the cell. Second, they have receptors and channels that let certain molecules, like ions, nutrients, wastes, and metabolic products,
  • Third, they divide metabolic processes that are necessary but incompatible that take place within organelles.

A population of Drosophila simulans carries three alleles at the white locus: the wild-type allele at 86 percent, w1 at 9 percen
vladimir1956 [14]

Answer:

the population is polymorphic.

Explanation:

Polymorphism is the discontinuous genetic variation that leads to the production of varying unique kinds or forms of individuals within the population of an individual species.

Take for instance, allelic polymorphism is seen in the presence of multiple alleles that is produced within the members of an individual species as in peppered moths, human blood groups, and two-spotted ladybugs.

We have different causes of polymorphism: polymorphism can be sustained by an equity among variation developed by new mutations and natural selection. Genetic variation might be due to frequency-dependent selection.

An article in the Los Angeles Times (Dec. 3, 1993) reports that 1 in 200 people carry the defective gene that causes inherited c
Alborosie

Answer: 5

Explanation:

Since 1 out of 200 people carry the defective gene that causes inherited colon cancer.

In a sample of 1000 individuals, we say

1 = 200

y = 1000

cross multiply

y x 200 = 1000 x 1

200y = 1000

y = 1000/200

y = 5

Thus, in a sample of 1000 individuals, approximately 5 will be carriers
