The epiglottis is pushed downward and the larynx is lifted up to meet it when we swallow. True False

Biology
1 answer:
Alex17521 [72]3 years ago
8 0

Answer:

The correct answer is true.

Explanation:

Swallowing of food is the process of passing the food from the mouth to the stomach through the way of the throat (pharynx) and esophagus. This process takes place in three stages:  oral, pharyngeal, and esophageal stages  

During the pharyngeal stage, epiglottis which is a leaf-shaped flap of cartilage located at top of the larynx (a muscular organ forming voice box) perform functions in response to the swallowed food as the larynx lift up or rises inside the neck to close the epiglottis while the epiglottis moves downward to cover it, providing more airway protection.

Thus, true is the correct answer.

Which partly explains why the domestication of animals tended to increase the human food supply?
Alenkinab [10]

Answer:

A

Explanation:

Before domestication of animals, these animals were wild and early humans used to hunt for food. The hunting process  was not always successful and took a lot of energy from the body. Domestication of these animals made food available and other conveniences. An example is cows that emanated from the domestication of wild aurochs. They provided the milk and meat for humans and also labored in the farm in the cultivation of domesticated plants.

fomenos

Answer:

The artificial reef would decrease erosion of the coastline.

Explanation:

Artificial reefs are created in area where there is little uderwater topography or near established coral reefs to imitate or even substitute for natural coral reefs where they are absent or endangered due various factors which are mostly human in nature. The artificial serves to provide a habitat for marine organisms and ensure more biodiversity around the area by providing shelter from predation and surfaces for encrusting organisms such as corals and sponges to grow on. The growth of these lower level food chain organisms attract larger predator organisms thereby increasing the biodiversity in the area.

Artificial reefs are made from a variety of materials such as shipwrecks, construction debris, oil rigs, concrete, and any other man-made objects. Since reef structures protect shorelines against waves, artificial reefs would decrease the erosion of the coastline providing benefit to the people living along the coastline by preventing the destruction of beaches and coastal property,
