12 If pressure is applied to a rock until its volume is
mote1985 [20]

Answer: The correct answer to the question is option 2

If pressure is applied to a rock until it's volume is reduced by one half how the new density compares to it's original density is ; THE NEW DENSITY IS TWICE IT'S ORIGINAL DENSITY.

Explanation: Density is defined as mass divided by volume,density increases with pressure and it's determined by spaces between atoms in the object being measured.

Density is directly proportional to Pressure,so when pressure increases, Density increases and when pressure decreases,density decreases.

Density is indirectly or inversely proportional to temperature. so when pressure and density increases, temperature remains constant.

This is applicable to the scenerio with the rock in the question,as the pressure on the rock is increasing,the density is increasing too.

True [87]

Answer:

Gene: The hereditary material made up of alleles.

Alleles: The alternative forms of a gene.

Dominant: An allele or trait that masks the effect of recessive allele or trait.

Recessive: An allele or trait that gets suppressed by the dominant allele or trait.

genotype: The genome of a particular organism of the genes which make up an organism.

phenotype: The physical traits or characteristics of an organism.

test- cross: A cross in which the dominant and the recessive trait offsprings are crossed to depict whether the dominant organism is homozygous or heterozygous.

law of independent assortment: Alleles of different genes get assorted independently into gametes.

law of segregation: allele pairs segregate during gamete formation and unite at the time of fertilization.

product rule: Independent evens can be calculated by multiplying the independent probabilities.

Addition rule: The probability which shows that one event would occur in a mutually exclusive event.

co-dominant: When the dominant and the recessive trait occur and the organism shows both the characteristics of the dominant and the recessive trait.

incomplete dominance: when the dominant trait is not fully dominant over the recessive trait. As a result, individuals are produced which show neither the dominant or the recessive trait. A new trait is developed in them.
