Structure moves up against epiglottis when food is swallowed to prevent passage of food into it.

Biology
1 answer:
borishaifa [10]3 years ago
6 0

Answer:

The correct answer is A. The larynx moves up against epiglottis when food is swallowed to prevent passage of food into it.

Explanation:

The epiglottis is a moist, cartilaginous structure that is part of the cartilaginous skeleton of the larynx. It also marks the boundary between the oropharynx and the laryngopharynx. The epiglottis obstructs the passage of the bolus at the time of swallowing preventing it from going to the respiratory system.

Larynx closure occurs when the vestibular and vocal folds approach the midline during swallowing. Occasionally, when you eat very fast, solid foods or liquids can enter the larynx.

The slower an object moves the more kinetic energy it has.<br><br> True<br><br> False
Lady_Fox [76]
False , because its backwards 

There will be more energy 'locked away' in a massive lorry that is moving at 20 m/s than in a motorbike travelling at the same speed.



Also the faster it goes the more kinetic energy the lorry will have.

A lorry moving at high speed will have much more kinetic energy than a lorry moving at low speed.

Therefore a fast moving car or lorry will cause more damage in an accident than a slow moving one because this kinetic energy has to be turned into other forms including sound, heat and stress on the other vehicles.

The kinetic energy of an object therefore depends on two things:
(a) the mass of the object (m)
(b) its speed (v)

The formula for kinetic energy of an object of mass m travelling at speed v is:

Many people believe that vitamins and minerals are essentially the same type of nutrient but they are not: one is an organic mol
Minchanka [31]

Answer:

The correct statements are listed below.

Explanation:

Vitamins are organic and minerals are inorganic.

Organic compounds comes from living things.Vitamins generally exist as organic compounds for example all the vitamin such as vitamin A, Thiamine,riboflavin,biotin,pyridoxin,vitamin c,vitamin E, vitamin K exist as organic compounds.

On the other hand minerals are found in inorganic form for example nitrogen is found as nitrate and nitrite,phosphorus is found as phosphate group,phosphoric acid.
