Where is air almost completely humidified? in the lungs in the trachea in the alveoli in the nose?

Biology

None of the provided choices provide a completely correct answer. In fact, 75% of humidification takes place in the nose and mouth, with the rest taking place in the trachea. When you breath in, mucous membranes inside the nose and mouth release moisture to air. It is estimated that the average adult evaporates 200 to 300 ml of water per day during this process. The process is very efficient: while  breathing in through nose or mouth, the mucous membranes are cooled down.  During breathing out, this cooling effect causes condensation of some of the moisture in the air coming from the lungs, thereby moisturizing the mucous membranes

A 6,000 kg train car is moving to the right at 10 m/s and connects to a 4,000-kg train car that wasn't moving. What is the veloc
SIZIF [17.4K]

6 m/s

This type of collision is a <u>Inelastic collision </u>

Explanation:

We begin by finding the momentum of the initial train car;

Remember that momentum is given by the formulae mass (kg) * velocity (m/s)

Therefore;

Momentum = 6000 * 10

= 60,000 kg⋅m/s

The other car has zero momentum because;

4000 * 0

= 0

When the two train cars collide, the total momentum will be;

60,000 + 0 = 60,000

Therefore to find the velocity, well use the same formulae;

p = mv  whereby;

p – momentum

m – mass

v – velocity

60,000 = (6000 + 4000) * v

v = 60,000 / 10,000

v = 6

= 6 m/s

This is an elastic collision because we are assuming that no energy is lost in the collision. Most collisions, however, are not elastic but rather inelastic. In inelastic collision some of the kinetic energy is lost to the environment in some other form of energy such as heat energy.

What is the difference between asexual and sexual reproduction? This is a Science question. PLZ HELP!!!!!!
Olegator [25]

Asexual reproduction only requires one organism. It is normally faster and that’s how organisms make more in a short amount of time. Sexual reproduction uses 2 organisms and it gives the baby more diversity so it can adapt to the environment.

Biotechnology has allowed us to genetically modify corn with a gene that acts as a pesticide. What could be a possible environme
Sergio [31]
<span>Since a gene that acts as a pesticide is inserted into a corn, that corn is now safe from insects. This will happen because the corn will probably synthesise protein according to that inserted DNA sequence and that protein will serve as a repellent to the insects. However, the Red Queen's hypothesis in evolution explains that organisms must constantly adapt and evolve in order to survive. This refers to insects. If they could not eat genetically modified corn, they would extinct. So, they must adapt or evolve in order to survive. So, it is expected that insects that are resistant to this specific pesticide would develop through the time.</span>
