Answer:
When an electron absorbs energy, it will move up from a lower energy level to a higher energy level, called the "excited state" of the negatively-charged subatomic particle.
Chlorine is represented by the symbol Cl
Using the relationship M1V1 = M2V2 where M1 and M2 are the molar concentrations (mol/L or mmol/ml) and V1 and V2 are the volumes of the solutions, we can arrive at the following answer for the given problem:
<span>15.0M (L of stock solution) = 2.35M (0.25L) *all volumes were converted to liters.
L of stock solution = (2.35*0.25)/15.0
Therefore, 0.0392L or 39.17 ml of stock solution is needed. </span>

Selective breeding
The Alleles
DNA
X and Y chromosome from mother and father
Nucleus
Gene
<u>Explanation:</u>
- In selective breeding, a specific trait of the animal is considered and the gene coding for that trait is used to create new breeds. Example - cow producing lot of milk.
- Genotypes are always expressed by the alleles.
- Example - Genotype of Tall plants would be TT or Tt
- Information is passed from parents to offsprings from the information stored in DNA.
- A gender of an individual is determined by the x chromosomes of mother and X and Y chromosome of father.
- X chromosome from mother and X chromosome from father would form a female and X chromosome from mother and Y chromosome from father would form a male.
- DNA is located inside the nucleus of the cell
- Gene is the segment of chromosome that codes for a specific protein. The non coding segment of chromososme is heterochromatin.
