Answer: the correct option is A ( The spotted coat is an INHERITED TRAIT, and the ability to perform tricks is a LEARNED TRAIT.
Explanation:
Dog is one of the first domesticated animal by man because it has the ability to perceive information and retain it as knowledge for applying to solve problems.
Therefore, the ability to perform tricks is a LEARNED TRAIT. This is so because they have acquired the ability to understand and communicate with humans, and they are uniquely attuned to human behaviors.
INHERITED TRAIT is a trait that can be passed down from one generation to another which are found in genes within the strands of dogs DNA. Some of the inheritable traits includes the following:
- coat color,
- ear type, and.
- tail style.
Therefore the spotted coat is an INHERITED TRAIT

Answer:
Explanation:
Mallabone’s tests suggest there’s no risk the jacket liner will explode or heat up so much that it risks causing burns. The reaction also doesn’t produce acidic byproducts. And because calcium oxide doesn’t react with humidity (water vapor in the air), the liners can be stored for long periods and still work when needed.
Calcium oxide: A substance that gives off heat as it chemically reacts with water. Its chemical formula is CaO (which means each molecule is made up of one calcium atom and one oxygen atom).
Exothermic reaction: A chemical reaction that generates heat as it proceeds. (In Greek, “exo” means outside and “therm” means heat.)
Thought this might help ;)
Strategy: with the volume, pressure and temperature you can find the number of moles.
With the number of moles and the mass in grams you can find the molar mass of the gas, and with the molar mass you can figure out the gas.
1) pV = nRT => n = pV / RT
R = 0.082 atm*liter / mol*K
T = 62 + 273.15 = 335.15 K
p = 1.98 atm
V = 0.752 liter
n = (1.98 atm * 0.752 liter) / [0.082 atm* liter / (mol * K) * 335.15K] = 0.05418 mol
2) molar mass = mass / n = 2.49 g / 0.05418 mol = 45.96 g/mol ≈ 46.0 g/mol
So, now you must compare this molar mass with the molar masses of the list of choices.
For example, for NO2 the molar mass is 14 g/mol + 2 * 16 g/mol = 14 g/mol + 32 g/mol = 46 g / mol.
Given that NO2 is in the list of choices, you can conclude that the gas is NO2.
