Answer:
Graduated Cylinder The most precise way to calculate the volume of an object, especially in the case of an irregularly formed object, is to immerse it in water and measure how much water it displaces. What is the more precise mass or volume measurement? Generally, mass is calculated by tools called balances.

Answer:
Let's recall Mendel's law of independent assortment that states, "During the formation of gametes, alleles of genes assort independently into each gamete"
How can the random distribution of alleles result in a predictable ratio?
For example, We have a trait for flower color either yellow or white, and the alleles for the flower color are Y and y. The yellow flower color is a dominant trait, and be expressed if plant has YY or Yy genotype. We cross a plant with genotype Yy with another plant Yy.
P1 Yy x Yy
F1 YY : Yy: Yy: yy
Phenotype Yellow: yellow: yellow: white
Genotypic ratio 1 : 2 : 1
Phenotypic ratio 3 : 1
So, we see that phenotypic ratio is different from genotypic ratio. Although the distribution of alleles is random but still there are only four possible outcomes for a trait. Hence, we can predict the phenotypic and genotypic ratio of offspring by drawing a punnet square or gamete formation.
Answer:
<h2>Gregor Mendel used "Cross Polination"of parents that have different traits to produce offsprings.</h2>
<span>There are at least three types of hypotheses which attempt to explain the origin of life on Earth. The first and oldest of these hypotheses suggest that life was created by a supreme being or spiritual force. Most cultures and religions have their own explanations of creation that are passed down from generation to generation. Because these ideas cannot be proved nor disproved, we consider them outside the boundaries of science. For that reason, they will not be pursued here and are left to each individual to decide. </span>
