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.

Amanda [17]
An insect bite on the face produces a break in the skin which introduces the normal skin flora (usually <em>Staphylococcus </em>and <em>Streptococcus</em>) to the sterile subcutaneous tissue causing inflammation. The inflammation of the subcutaneous tissue is called cellulitis. Since the infection is in the face, then it can travel from the infected site to the meninges through the cavernous sinuses and cause bacterial meningitis.

Volgvan

Answer:

b. Feedback response

Explanation:

Homeostasis is the ability of the system to preserve a constant state despite external inputs. Homeostasis requires the constant monitoring of internal environmental conditions in order to keep the balance of the system. Conversely, a feedback response enables to maintain a change observed in the internal conditions of a given system (for example, a living organism). This change is regulated by the interaction among different elements in the system including effectors, sensors and stimuli, which work together to maintain the feedback state.

Answer: Lack of energy

Explanation:

Oxygen is needed in a process known as Respiration where it is used to produce energy from glucose. This energy is what the cell uses to continue whatever functions that it carries out which are needed for the body to survive. If the cells don't get oxygen, they can't make energy and if they can't make energy, they die.

Some cells are more important than others and so will need a constant supply of oxygen. The brain for instance requires 20% of the oxygen used in the body. If the body suffers from a lack of oxygen for whatever reason, brain cells begin to die within about 4 minutes.

The brain is extremely important as it directs the body. If the cells there begin to die, the body deteriorates and the body stops engaging in certain processes due to a lack of direction from the brain. This coupled with the other cells dying around the body will lead to even more deterioration till the body dies.
