Describe the molecular structure of water, and explain why it is a polar molecule

Biology

lys-0071 [83]3 years ago
6 0
A water molecule, in light of its shape, is a polar particle. That is, it has one side that is decidedly charged and one side that is adversely charged. The particle is comprised of two hydrogen iotas and one oxygen molecule. The bonds between the particles are called covalent bonds, on the grounds that the molecules share electrons.

all this below

Each hydrogen atom is bonded to the oxygen atom with a single bond.

The oxygen atom has two lone pairs.

The molecule is bent.

Oxygen is more electronegative than hydrogen.

Each O-H bond is polar.

The molecule is asymmetrical.

The asymmetry and the polar bonds produce an overall molecular dipole.

The oxygen atom has a partial negative charge, and the hydrogen atoms have a partial positive charge.

Which property of matter is useful for holding papers and photos on refrigerator doors?
Flauer [41]

Answer:

Magnetism

Explanation:

The refrigerator doors are made of <u>metal</u>, and we use <u>magnets</u> to hold papers and photos on their surfaces. Magnets attract metals such as iron, cobalt, nickel, etc. That is due to the physical property of matter called <u>magnetism</u>, which is related to the attraction force generated by a magnetic field.

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

Answer: if they help you break down food

Explanation:

Mutualism is a biological relationship between TWO or more organisms of different species (inter-specie) in which one or more benefits.

A good example is bacteria in the human intestine that helps to break down cellulose contained in food, thus benefitting humans.
