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.

½H2(g) + ½I2(g) → HI(g), ΔH = +6.2 kcal/mole 21.0 kcal/mole + C(s) + 2S(s) → CS2(l) What type of reaction is represented by the
wlad13 [49]

<u>Answer:</u>

Exothermic Reaction are those reaction, in which energy is released while in endothermic reaction are those, in which energy is absorbed.

<u>Explanation:</u>

First Reaction:

As in this reaction, energy is released

½H2(g) + ½I2(g) → HI(g), ΔH = +6.2 kcal/mole

so it is <em>exothermic reaction</em>

Second reaction:

As in this reaction, energy is absorbed

21.0 kcal/mole + C(s) + 2S(s) → CS2(l)

so it is <em>endothermic reactions</em>.

Type the correct answer in each box.
Arturiano [62]

Answer:

5SiO2 + 2CaC2 = 5Si + 2CaO + 4CO2

Explanation:

balancing equations is a lot of trial and error. My strategy to approaching this equation was to get the O's balanced. After trying several combonations I found that I needed 10 O's on each side of the equation for the other elements to match up. After I balanced the O's, I balanced my C's to 4 on each side. Then I balanced my Ca's to have 2 on each side. And last but not least I balanced my Si to have 5 on each side.
