The table below shows the dimensions of two colored cubes.
Lelechka [254]

Answer: The correct answer is black because the product of its side and mass is lower.

Explanation: Density of a substance is defined as the mount of matter that can be stored in a given volume.

Mathematically,

Density=\frac{Mass}{volume}

As, density is inversely proportional to the volume of the substance.

The substance will be more denser if it has less volume and it will be less denser if the volume is more.

We are given two cubes having different sides.

Volume of the cube is calculated by using the formula:

V=a^3

where, a = side of the cube.

Black: The side of this cube is 2 and volume will be = 2^3=8cm^3

Yellow: The side of this cube is 3 and volume will be = 3^3=27cm^3


As, the volume of black cube is less. So, this cube will be more denser.

Density of black cube: \frac{48}{8}=6g/cm^3

Density of Yellow Cube: \frac{135}{27}=5g/cm^3

Hence, black cube will be more denser  because the product of its side and mass is lower.

The following questions refer to the essential steps in Meiosis described below.
juin [17]

Answer:

3. Separation of sister chromatids

Explanation:

Before entering mitosis or meiosis, DNA contained in a cell duplicates and  and each chromosome will have two sister chromatids.

  • In mitosis the sister chromatids separate to produce two daughter cells that have the same information as the original cell before the DNA duplicated.
  • On the other hand, meiosis consists of two cell divisions. During meiosis I, homologous chromosomes separate, producing two daughter cells that have half the information the original cell had, but each chromosome still has two sister chromatids. During meiosis II, the sister chromatids separate, and each daughter cell produces two more daughter cells, that now have a single homologous chromosome of the pair, and which has a single chromatid.
