if the ratio of the ages of kisii and esinam is 3:5 and that of Esinam and Larry is 3:5 and the sum of the ages of all three is

larisa [96]

Answer:

The age difference between the oldest and the youngest is 48.

Explanation:

Given the following data;

The ratio of the ages of Kisii (K) and Esinam (E) is 3:5.

The ratio of the ages of Esinam (E) and Larry (L) is 3:5.

The sum of the ages of all three is 147.

Since the age of Esinam is common in both ratios, we find the lowest common multiple (LCM);

LCM of 3,5 = 15.

Hence, the ratio of the three ages is now;

K:E:L = 9:15:25

Let their ages be denoted by x;

$K:E:L = 9x:15x:25x$

The sum of all three ages is;

9x + 15x + 25x = 147

49x = 147

x = 147/49

x = 3.

To find the age difference between the oldest and the youngest;

The oldest is Esinam = 25x

The youngest is Kisii = 9x

Therefore, 25x - 9x = 16x

Substituting the value of x, we have;

x = 3; 16x = 16(3) = 48.

The age difference between the oldest and the youngest is 48.

How do DNA, chromosomes, and genes work as the instructions for heredity?

Margarita [4]

DNA or deoxyribonucleic acid is the molecule in living organisms wherein the genetic code or genes is stored. The structural conformation of DNA in the nucleus of the cells is called chromatin and in cell division, chromatin is grouped into a certain number (46, in humans, for instance) called chromosomes.

DNA provides instructions for hereditary such that a part of DNA is transcribed into messenger RNA or mRNA for the genetic code to be transported outside the nucleus. The mRNA is then translated into polypeptides to form proteins that form specific functions in the human body.

What subatomic particles are involved in chemical bonds

scoray [572]

Answer:

Actually, the ELECTRON: Negatively charged particles in an atom. Electrons, which spin around the protons and neutrons that make up the atom's nucleus, are essential to chemical bonding.

What is the essence of the catalase test?

garik1379 [7]

Explanation:

Catalase test demonstrate the presence of an enzyme called catalase, that catalyses the release of oxygen from hydrogen peroxide. It is used to tell the difference between the non-catalase producing bacteria from those bacteria that produces an enzyme catalase. Catalase is produced by the bacteria that respire using oxygen. If an organism produces catalase, bubbles of oxygen are produced when hydrogen peroxide is added to it.

Would a bacterial cell undergo mitosis in the same way as a eukaryotic cell? Why or why not?

nikklg [1K]

Unlike eukaryotes, prokaryotes (which include bacteria) undergo a type of cell division known as binary fission. In some respects, this process is similar to mitosis; it requires replication of the cell's chromosomes, segregation of the copied DNA, and splitting of the parent cell's cytoplasm.
