Answer:
Bilateral: When something is bilateral it has two sides or it affects both sides of something. Discussions between two political parties are called bilateral because both sides get to share their views. Bilateral comes from Latin: bi means "two" and lateralis means "belonging to the side."
Endotherm: is an organism that maintains its body at a metabolically favorable temperature, largely by the use of heat set free by its internal bodily functions instead of relying almost purely on ambient heat
Subspecies: In biological classification, the term subspecies refers to one of two or more populations of a species living in different subdivisions of the species' range and varying from one another by morphological characteristics. ... In the wild, subspecies do not interbreed due to geographic isolation or sexual selection
Arthropod: Arthropoda, such as an insect, spider, or crustacean.
Micrometer: an instrument used with a telescope or microscope for measuring very small distances. 2 : an instrument having a rod moved by fine screw threads and used for making exact measurements. micrometer.
Hypothermia: Hypothermia is a potentially dangerous drop in body temperature, usually caused by prolonged exposure to cold temperatures. The risk of cold exposure increases as the winter months arrive. But if you're exposed to cold temperatures on a spring hike or capsized on a summer sail, you can also be at risk of hypothermia.
Polymorph: Polymorphism is the ability of a substance to crystallize into different crystalline forms. These crystalline forms are called polymorphs or crystalline modifications. Polymorphs have the same liquid or gaseous state but they behave differently in the solid state.

Answer:
D. protons that is the answer
Answer:
the number of protons and neutrons in an atom
Explanation:
To find the atomic number you just have to add the protons to neutrons.
Both the pure hydrogen and hydrogen bromide is held by weak intermolecular forces of attaction between molecules. Bromide has larger size of electron cloud than Hydrogen, leading to a greater extent of polarisation of the electron cloud. This results in stronger van der Waals' forces of attraction in hydrogen bromide compared to the pure hydrogen. More energy is required to break the stronger bonds in hydrogen bromide than pure hydrogen, leading to a higher boiling point in hydrogen bromide. Thus, pure hydrogen has a lower boiling point.
Explanation:
the strength of intermolecular forces of attraction rely on the size of the electron cloud. the greater the atomic number, the greater the size of the electron cloud and thus, the stronger the forces of attraction.
When asnwering a qn, you want to first state the structure and bonding of the compound, then compare the size of their electron clouds.
Answer structure:
greater size of electron clouds -> greater extent of polarisation of electron cloud -> stronger van der Waals' forces of attraction -> more energy required to overcome the bonds -> higher boiling point
