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.

a) What is the role of protons in an atom?
b) How do we determine how many protons are in an atom?
Answer:
The number of electrons, in turn, determines the chemical properties of the atom.
Protons contribute to the mass of an atom and provide the positive charge to the nucleus. The number of protons also determines the identity of the element.
Electrons have a negative charge. Since the atom is electrically neutral, the number of electrons must equal the number of protons.
The electrons arrange themselves in energy levels around the nucleus. The outermost or valence electrons of an atom are the ones that take part in chemical reactions. An element’s chemical properties depend on its valence electrons.

Which change is likely to happen to an atom of the element strontium (Sr) during bonding?
(1 point)
It will gain electrons, forming a positive ion.
It will gain electrons, forming a positive ion.
It will give up electrons, forming a negative ion.
It will give up electrons, forming a positive ion.
It will gain electrons, forming a negative ion.
Answer: It will give up electrons, forming a positive ion.
During bonding, strontium atom will give up electrons, forming a positive ion.
STRONTIUM:
Strontium (Sr) is an element in group 2 of the periodic table. Just like every other element in group 2, strontium posseses two valence electrons in its outermost shell. Strontium will undergo bonding with other atoms by losing its two (2) valence electrons to form a cation i.e. a positively charged ion. Therefore, strontium atom will give up electrons, forming a positive ion when it undergoes bonding.Learn more at: https://brainly.com/question/21085681?referrer=searchResults

An ionic bond would most likely form between elements of which two families on the Periodic Table?
Answer:
Ionic bonds can form between nonmetals and metals, while covalent bonds form when electrons are shared between two nonmetals.
Explanation:
An ionic bond is formed between the electropositive and electronegative bonds. In the periodic table, it is formed between s block and p block elements.
What are chemical bonds?There are different types of chemical bonds: Ionic bonds, covalent bonds, and coordinate bonds.
Ionic bonds, also known as electrovalent bonds, are a type of linkage created in a chemical molecule by the electrostatic attraction of ions with opposing charges. When the valence (outermost) electrons of one atom are permanently transferred to another atom, a bond of this kind is created.
It takes place in positively charged cation and negatively charged anion. This type of bond is seen in NaCl, CaCl2, and other molecules.
Metal and non-metal, ionic bonding form. Ionic bonds, as opposed to covalent ones, involve the transfer of valence electrons between atoms.

5g of carbon?
Answer:
12 atoms of carbon
Explanation:
(6.023X10^23)/12 atoms of Carbon.
There are 0.42 moles of carbon atoms in 5g of carbon.
HOW TO CALCULATE NUMBER OF MOLES:The number of moles in a substance can be calculated by dividing the mass of the substance by its molar mass. That is;no. of moles = mass (g) ÷ molar mass (g/mol)
According to this question, the mass of carbon is 5g. The molar mass of carbon is 12g/mol.No. of moles = 5g ÷ 12g/mol
No. of moles = 0.42moles
Therefore, there are 0.42 moles of carbon atoms in 5g of carbon.
