Answer : Option A) Translation
Explanation : A composition of reflections over parallel lines is the same as a <u>Translation.</u>
To identify if the composition of reflections over parallel lines are same as translation or not?
We can check using a picture of some shape in the plane. Place the picture on the right side of two vertical parallel. Now, we can see the reflected the shape over the nearest parallel line, then check the reflection over the other parallel line. We see that the shape winds up in the same orientation, like it was just shifted over to the right. Hence, it is translation.
If an atom gains an electron and gets a negative charge because of it, it is a negatively charge ion AKA an anion.
Environmental Chemistry studies the health hazards associated with lead, which is dangerous to humans.
Environmental Chemistry studies chemicals present in air, water and soil and their impact on humans and their environment.
Now, it was discovered that even low doses of lead particles in the paint when inhaled or ingested caused damaging effect to the body such as Impaired balance, seizures, ataxia and even death.
With the role of Environmental chemists in thier research and findings, the world has been informed on the negative effect on the expose of lead and other heavy metals like it to man and his environment.
