the mass number for an atom is numerically equal to which quantity
Answer:
The mass number of an atom is equal to the number of protons plus the number of neutrons that it contains. In other words, the number of neutrons in an atom is its mass number minus its atomic number.
Explanation:
protons
The mass number of an atom is its total number of protons and neutrons. Atoms of different elements usually have different mass numbers , but they can be the same. For example, the mass number of argon atoms and calcium atoms can both be 40.

If a cell has 4 chromosomes at the beginning of meiosis, how many chromosomes will be in each cell at the end of meiosis?
Answer:2. Mitosis would produce identical daughter cells with the same number as the parent cell. Meiosis would product sex cells with one-half the amount of genetic material as the parent cells.
Explanation:
If a cell has 4 chromosomes at the beginning of meiosis then the daughter cell will have TWO chromosomes at the end of meiosis.
Meiosis is a type of reductional cell division by which a parental cell duplicates its genetic material (DNA) and then divides twice to produce four (4) daughter cells having half of the genetic material.These successive cell division cycles are known as Meiosis I and Meiosis II.Meiosis is a sexual mode of reproduction that produces gametes or geminal cells, which fuse during the process of fertilization to form a zygote.
In conclusion, if a cell has 4 chromosomes at the beginning of meiosis then the daughter cell will have TWO chromosomes at the end of meiosis.

An unknown material has a mass of 4.5 g and a volume of
6.75 cm3. What is the density
Answer:
0.67 cm³Explanation:
The density of a substance can be found by using the formula
[tex]density = \frac{mass}{volume} \\[/tex]
From the question
mass = 4.5 g
volume = 6.75 cm³
We have
[tex]density = \frac{4.5}{6.75} \\ = 0.6666666...[/tex]
We have the final answer as
0.67 cm³Hope this helps you
