Why do phospholipids form a bilayer in water?

Biology

When Phospholipds are mixed with water , they spontaneously rearrange themselves to form the lowest free- energy configuration. this means that the hydrophohobic regions find ways to remove themselves from water , while the hydrophilic regions interact with water. the resulting structure is called a lipid bilayer.

Answer:

The fatty acid tails are cluster together to form the phospholipid bilayer.

Explanation:

A phospholipid is an amphipathic molecule having a hydrophilic head and hydrophobic tail. Phospholipid consists of three components such as phosphate head, glycerol, and Fatty acid tails. The phosphate head is the water-loving side. It comes in contact with water. The fatty acid tail is a water-hating side. They cluster together and don't allow water to pass through them. Thus another phospholipid layer forms inside the cell forming a lipid bilayer. In the lipid bilayer, the middle layer is lipid tails while outer and inner are phosphate heads.

-how are the major sources of water pollution different between developing and developed countries?
victus00 [196]
Take India for example.... people use the bathroom and bathe in rivers! Now lets say we look at the US our pollution comes from factories, trash that people dont throw away, fertilizers and many more... but the difference is, that in developed countries like the US our water is filtered.... And in India water is not safe to drink

~~9. what are the haploid reproductive structures of fungi called? (1 point)
Katarina [22]
The correct answer is the spores. Fungi reproduce asexually by budding, fragmentation, or spore production. Fragments of hyphae can grow new colonies. Mycelial fragmentation occurs when a fungal mycelium separates into pieces with each component growing into a separate mycelium. Spores are usually haploid and unicellular and are produced by meiosis in the sporangium of a diploid sporophyte.

In a population of rabbits, there are 496 black rabbits and 27 white rabbits. Fur color is determined by a pair of alleles where
Troyanec [42]

Answer:

0.96

Explanation:

It is given that

B is the dominant allele which represents the black color

and b is the recessive allele which represents the white fur.

B being dominant will result into black color fur for genotype "Bb"

Given -

Frequency of black fur allele (p) is 0.8

As per Hardy Weinberg's  first law of equilibrium

p + q = 1\\

Substituting the value of p in above equation, we get -

q = 1-p\\q = 1-0.8\\q= 0.2

q represents the frequency for white fur allele

Frequency of white fur phenotype is

q^2\\= 0.2^2\\= 0.04

Frequency of homozygous black fur phenotype (BB) is

p^2\\= 0.8^2\\= 0.64

As per Hardy Weinberg's second law of equilibrium -

p^2 + q^2 + 2pq = 1\\0.64 + 0.04 + 2pq = 1\\2pq = 1 - 0.68\\2pq = 0.32\\

Combined frequency of homozygous and heterozygous black fur phenotype is

0.64 + 0.32\\= 0.96
