Answer:
1' and 5' carbon.
Explanation:
DNA is the genetic material of almost all the living organisms but exceptions are involved in case of some viruses that contains RNA as their genetic material.
The DNA consists of the nitrogenous base, dexoyribose pentose sugar and the phosphate group. The base is attached with the sugar on the 1' position. The phosphate group is linked with the sugar at 5 position of the dexoyribose sugar.
Thus, the correct answer is 1' and 5' carbon.
1)Density is a physical property because its measurement or observation does not alter the chemical composition of a substance.
6)Yes
8)A characteristic property is a chemical or physical property<span> that helps identify and classify substances.</span>

Ionic compounds are compounds that are composed of oppositely charged ions, anions and cations. The force which holds the two ions (charged atoms) together is called the electrostatic force, and the bond that exists between them is called an ionic bond.
An ionic bond can be formed after two or more atoms loss or gain electrons to form an ion. Ionic bonds occur between metals, losing electrons, and non metals, gaining electrons.
Monoatomic elements are elements that are stable as single atoms. The chemical elements which are stable single-atom molecules at standard temperature and pressure (STP) are noble gases. These are helium, neon, argon, krypton, xenon, and radon.
Ionic compounds are made up of oppositely charged ions which are held together by strong electrostatic force of attraction. Due to this reason, they are hard solids.

Through J.J. Thomson's creative mind, he proposed the "Plum Pudding Theory" which shows the scientific model of an atom wherein electrons are attached to the body of the atom as if it was like a raisin in a pudding. He also consolidates the properties of atoms at that time such as: electrons are negatively charge particles and and atom has neutral charge.
Answer:
The answer is C
Explanation:
A lipid bilayer makes up the cell membrane because it is more like a chain link fence that is flexible allowing cell movement.
