4. E=mc²
Explanation:
The best approximation of the energy released during a nuclear fusion process can best be determined using the Einstein equation.
In nuclear reactions, mass and energy are equivalent:
E = mc²
E is the energy
m is the mass
c is the speed of light
- In nuclear reactions, some of the mass is converted into the energy.
- Therefore mass is not conserved in such equations.
- This is why they release huge amount of energy.
- From this equation, we know that the more mass loss, the more the energy that would be produced.
- In a fusion reaction, two light nuclei combines to form a heavier one.

The air can be considered polluted once harmful or toxic substances are being released and introduced into the air and can bring many types of diseases or health problems to the living organisms in it. Some actions can be done in order to remedy air pollution and these include: government passing regulatory laws, testing for car emissions and carpooling so there will be less driving.
Answer:
Yes
Explanation:
A high quality DNA sample will have a 260/280 ratio of around 1.8. This value means that the DNA is sufficiently pure and free from other contaminants that could affect downstream experiments and analysis.
The ratio for this sample is 0.489/0.257 = 1.9
This is close to 1.8, and therefore the sample is of sufficient quality ot use downstream.
<span>Mendel showed that the green-seed trait did not disappear but was only masked by breeding plants with only two alleles for the trait. After the cross of yellow seed, a small amount of offspring had green seeds. So, he concluded that the green-seed trait is masked by the dominant yellow-seed trait and that two alleles are necessary for green-seed trait to show up.</span>
Answer:
Answer is E.
Explanation:
Generally, sphincter are circular or ring - shaped muscles, surrounding the natural opening in the body. They control the movement of substances by opening and closing through expansion and contraction.
There are many sphincter in the body, examples are
* Cardiac sphincter...found at the upper area or portion of the stomach.
* Pupilary sphincter..found in the iris of the eye.
* Glisson's sphincter...controlling the secretion of the gall bladder,pancrease and the liver.
