Using the cell size and scale Interactive, the correct order of size, left to right, from smallest to largest is tRNA > influenza virus > E. coli bacterium Hepatitis virus > hemoglobin > phospholipid. The correct option is a.
<h3>What is t-RNA?</h3>
t-RNA is transfer RNA. It helps in transferring information from RNA to DNA or DNA to RNA.
t-RNA is present in viruses, so it will be smaller than the virus because they are present inside the virus. Phospholipids are chains of lipids. They are macromolecules.
Therefore, the correct option is a. tRNA > influenza virus > E. coli bacterium Hepatitis virus > hemoglobin > phospholipid.

Answer:
It is pure substance
Explanation:
Aerated water is a homogeneous mixture of carbon dioxide and water. It is not a pure substance. Carbon dioxide is a compound while oxygen and zinc are elements which are a type of pure substance.
Answer:
The option C is the false statement
Explanation:
Ionization energy is the energy needed to completely pull out an electron from the valence electron of a gaseous atom.
The given values of ionization energy (kJmol⁻) for a main group element is: IE₁ = 100; IE₂ = 2200; IE₃ = 3300; IE₄ = 4100; IE₅ = 5200
Since<u> first ionization energy is very low</u> and the <u>difference between the first and the second ionization energy</u> for the given element is <u>very high</u>.
Therefore, <u>the given chemical element is most likely an alkali metal</u> belonging to the<u> group IA of the periodic table.</u>
As the alkali metals react with oxygen to form oxides. So, the given <u>element (J</u>) can react with oxygen to form <u>oxide of the formula J₂O</u>.
Since the given element has <u>low first ionization energy, thus it is reactive</u>. Therefore, the given element <u>can not exist as a free element.</u>
If the given chemical element belongs to <u>the period 3</u> of the periodic table, then it is should be the group IA alkali metal,<u> sodium</u>.
<u>Therefore, option C is the false statement.</u>
Answer:
The answer to your question is below
Explanation:
In sodium chloride, its atoms are attached by ionic bonding.
In sucrose, its atoms are attached by covalent bonding.
Characteristics of substances that have ionic bonding high melting and boiling points, they conduct electricity in solution, are crystals, ionic bonding is stronger than covalent bonding.
Characteristics of substances that have covalent bonding have low melting and boiling points, they do not conduct heat or electricity, covalent bonding is a weak bond.
According to the previous description, the correct answer is " Sodium chloride has a higher boiling point than sucrose"
Answer: Areas surrounded by water would have less of a change in temperature
throughout the year.
Explanation: Water has a higher specific heat index so it's temperature will be slow to rise. Water also holds heat longer than most material hence areas sorrounsing water will have less temperature change throughout the year.
