Which of the following describes the difference between nitrogen-14 and nitrogen-15?

1 answer:

7 0

Some of these can easily be eliminated by knowing that both nitrogen 14 and nitrogen 15 are isotopes ( same element, with the same amount of protons, but with different numbers of neutrons) of nitrogen. So if the only difference between nitrogen 14, 15 , and regular nitrogen is the amount of neutrons...how many protons and electrons should both nitrogen 14 and 15 have? After thinking, you should be able to eliminate A, B,and C.

UNO [17]

<h3>Answer;</h3>

There will be 4 different combination of chromosomes

<h3>Explanation;</h3>

A diploid cell is a cell that contains two sets of each chromosomes; thus a diploid cell with two pairs of homologous chromosomes has four chromosomes.
Gametes are produced through meiosis which is the type of cell division in which a parent cells divides into four daughter cells each with half the number of chromosomes as the parent, that is the cell are haploid.
Therefore, a diploid cell with two pair of homologous chromosomes will produce four haploid cells after meiosis each with two chromosomes.

Which of the following represents the correct format for the scientific name of an organism? Which of the following represents t

scZoUnD [109]

Answer:

Staphylococcus aureus

Explanation:

According to the rule of binomial nomenclature, the name of the organism is written in two parts that are-

1. Generic name- The first name which signifies the genus of the organism, the word represents the noun of the organism, the first letter of the word is always uppercase that is like in the "Staphylococcus"

2. The specific epithet-the second name of the organism represents the species which is usually a noun, and the first letter of species is always written in lowercase like in the aureus.

The scientific name should be written either in the italicised form or if not possible to write in the italicised form than underline the name.

Thus, Staphylococcus aureus is correct.
