Answer:
because when oxygen atom bonds with two hydrogen atoms they form water
Explanation:
A water molecule is formed by covalent bonds between an oxygen atom and two hydrogen atoms. The bond between hydrogen and oxygen involves unequal sharing of electron – it is a polar covalent bond. This is because the nucleus of the oxygen atom is more attractive to electrons than the nuclei of the hydrogen atom.

1. What percentage of the offspring will be heterozygous?
2. Why does each parent contribute only one allele to the offspring?
Answer:
1. 50%
2. Every gamete only contains 50% of the genetic information or half of the information for a gene.
Explanation: 1. Heterozygous means the pairs consist of a dominant and a recessive, or one big and one small letter, so only 2/4 or 50% are heterozygous.
2. Every sex cell has half of the chromosomes you need to make an embryo so you end up only having one allele as well
Heterogeneous means different
Here they are 2Total 4Percentage:-.
2/4×100=50%#2
It's because they only produce 50% not 100%
Explain the variation and distribution of expressed traits in a population in regards to the Sama-Bajau people and enlarged spleen. How does having an enlarged spleen benefit?
It is common for Sama-Banjou people to have an enlarged spleen, this is the result of environmental factors as a larger spleen helps them to dive better.
In most people, an enlarged spleen is not common and it is often related to specific conditions and diseases. Due to this, the percentage of people with an enlarged spleen is quite low.
Despite this, it has been found many Sama-Banjou people have an enlarged spleen and this is the result of environmental factors. Indeed, Sama-Banjou people have relied on diving to survive for centuries as they collect seashells from the seafloor.
This condition has led to bigger spleens, these bigger spleens increase the amount of oxygen while diving, and therefore, help them to dive for longer periods.

The property which would be expected to be true of a parallel universe would be that: They would have the same laws of physics.
Discussion:
A parallel universe by definition is; a separate universe or world that coexists with our known universe but is very different from it. a realm of existence and experience that is fundamentally different from the one that most humans share; a separate reality ultimately.
PS: Plato reflected deeply on the parallel realities, resulting in Platonism, in which the upper reality is perfect while the lower earthly reality is an imperfect shadow of the heavenly.

Which statement is true about the law of reflection?
The angle of reflected light is the same as the incoming angle of light.
The angle of reflected light distorts the image to appear larger or smaller.
The angle of reflected light is smaller than the incoming angle of light.
The angle of reflected light is larger than the incoming angle of light
Answer:
The law of reflection defines that upon reflection from a smooth surface, the angle of the reflected ray is equal to the angle of the incident ray, with respect to the normal to the surface that is to a line perpendicular to the surface at the point of contact.
The reflected ray is always in the plane defined by the incident ray and the normal to the surface at the point of contact of the incident ray.
The images produced by plane mirrors and curved mirrors can be understood by the law of reflection.
Law of reflection is defined as:
The principle when the light rays falls on the smooth surface, the angle of reflection is equal to the angle of incidence, also the incident ray, the reflected ray, and the normal to the surface all lie in the same plane.
What is Reflection of Light?
The process through which light rays fall on the surface and gets bounced back is known as a reflection of light.
Explanation:
Answer: The angle of reflected light is the same as the incoming angle of light.
Explanation:
The law of reflection states that the incident ray, the reflected ray, and the normal to the surface of the mirror all lie in the same plane. The angle of reflection is equal to the angle of incidence.

exchange of gases in the human breathing system takes place in the?
alveoli
ExplanationDuring gas exchange oxygen moves from the lungs to the bloodstream. ... This happens in the lungs between the alveoli and a network of tiny blood vessels called capillaries, which are located in the walls of the alveoli.
The exchange of gases takes place in the alveoli.
▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬
Additional information :- Alveoli are microscopic air sacs. They are the primary sites of exchange of gases. Gas exchange also occurs in lungs and tissues by diffusion.Atmospheric air contains little CO2, but blood flowing in pulmonary capillaries has a higher concentration of CO2.CO2 diffuses from higher concentration in blood across walls of alveolar capillaries to lower concentration in air in alveoli.Blood coming into pulmonary capillaries is oxygen poor and alveolar air is oxygen rich.Oxygen diffuses from higher concentration in alveoli across walls of alveolar capillaries to lower concentration in blood.▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬
