Which structure's primary function is to warm and moisten the air?a. nasal cavity
b. epiglottis
c. bronchus
d. bronchiole

Answers

Answer 1
Answer:

Answer: a. nasal cavity

Explanation:

The nasal cavity is a external opening of the respiratory tract. This involves two canal like cavities through which air enters the respiratory tract and moves out of the body. These are the two hollow spaces within the nose each of which consists of mucus and lined up with the hairs.

The primary function of the two nasal cavities is to moisturize, warm and filter the air entering the respiratory tract. These cavities filter out environmental contaminants like dust, pollen, molds and others.

Which model of the atom has electrons traveling in specific paths around the nucleus? Bohr's model Rutherford's model Thomson's model Dalton's model

Answers

The model of the atom that has electrons traveling in specific paths around the nucleus is Rutherford's model.

Therefore, the correct answer is option B

J. J Thomson proposed that the atom is a sphere of positively charged matter in which negatively charged electron are embedded.

In Rutherford's model of atomic structure, the electrons moves in orbits by electrostatic attraction to the positively charged nucleus.

According to Dalton's atomic theory, atom were indestructible and indivisible  solid particle.

Bohr's model made assumption that electron can only exist in circular orbits of definite quantum energy.  

According to the question, the model of the atom that has electrons traveling in specific paths around the nucleus is Rutherford's model.

Therefore, the correct answer is option B

How many grams is 5kg of tap water?

Answers

When you write "5 kg", the little 'k' in the middle stands for 1,000.
So '5 kg' means '5,000 g'.

It doesn't matter what substance you're working with.  It could be
tap-water, gold, air, or mud.  5 kg of it is still 5,000 grams of it.

1)why do we get electric shock while holding a live wire barefooted and not when wearing rubber shoes?

Answers

Electricity is always going to take the path of least resistance to ground. The rubber in your shoes is not a conductor of electricity, therefore you are not completing the circuit and you don't get shocked. Your bare feet, on the other hand ARE conductors of electricity, so when you hold the wire, you complete the circuit and become the path of least resistance to ground... ZAP!

A a0 is the amount of heat needed to raise the temperature of one kilogram of water one degree centigrade.

Answers

The correct answer that would best complete the given statement above would be the term KILOCALORIE. A KILOCALORIE  is the amount of heat needed to raise the temperature of one kilogram of water one degree centigrade. On the other hand, the amount of heat needed to raise the temperature of one gram of water one Centigrade degree is calorie. Hope this answer helps.

I got this correct on Odyssey-ware the answer is Kilocalorie
