The pharynx is the structure in the body that serves as a pathway of both air and food. How does the body make sure that food do

es not get into the lungs? The salivary glands secrete enzymes that pull food out of the air pathway. The small intestine pushes the air out of the digestive system. The pancreas breaks down food in the air pathway. The epiglottis closes the air pathway so that food will not enter it.

Answer:

The food is prevented to enter lungs as epiglottis closes the air pathway so that food can not enter.

Explanation:

The food we eat is converted into energy and essential nutrients by digestive system. The process of digestion starts from mouth when saliva is mixed with food during chewing. The esophagus is like a stretchy pipe that's about 10 inches (25 centimeters) long. It moves food from the back of your throat to your stomach. At the back of your throat a windpipe is also present, which allows air to come in and out of your body.

When we swallow the food, a leaf shaped cartilaginous structure called Epiglottis closes the wind pipe so that the food can not get to the lungs and cause problem. Once the food enters to the esophagus epiglottis returns to its position.

Answer:

D. The epiglottis closes the air pathway so that food will not enter.

Explanation:

The pharynx is the structure for both pathways of food and air, to keep food from getting into the lungs, the epiglottis closes the air pathway so the food won't enter the lungs, but instead enter the correct path. I also took the quiz on e d g e n u i t y and got it correct! :)

In science, what is artificial selection, and how does it work?
marysya [2.9K]

Answer:

Artificial selection, also called "selective breeding”, is where humans select for desirable traits in agricultural products or animals, rather than leaving the species to evolve and change gradually without human interference, like in natural selection.

Every spring in the southeastern United States strong thunderstorms are common. Frequently they lead to tornadoes which can have
svet-max [94.6K]

Answer:

c. Grasses and small shrubs would be the first plants to begin growing from the seeds that are in the soil.

Explanation:

This question depicts SECONDARY SUCCESSION, which is one of the two types of ecological successions where an area previously occupied by living organisms is disturbed by natural causes such as hurricanes, tornadoes etc. This is the case in this question where thunderstorms that lead to tornadoes leave a significant impact on the environment of the southeastern part of the United States.

According to the question, the tornado results in the uprooting of previously existing trees that has occupied that area. After the devastating effect of the tornado on the environment, changes occur rapidly since the soil of the environment are already rich in nutrients. The first plants to recolonize in secondary succession are annual plants consisting of grasses and shrubs whose seeds were not destroyed by the tornado. These forms of plants can also be called PIONEER species as far as secondary succession is concerned.

Hence, based on the question, grasses and small shrubs would be the first plants to begin growing from the seeds that are in the soil.

Lynna [10]

<u>Answer</u>: can be almost any size

<u>Explanation</u>: Plants are extraordinary organisms that come in a variety of shapes and sizes. The smallest is the watermeal (<em>Wolffia globosa</em>). With sizes of approximately 2 millimeters (0.079 in), it is also the smallest flowering plant in the world. One of the largest are the sequoia with heights of 70-85 meters and ages of over 3000 years old.

Plants are usually divided into two groups depending if they produce seeds or not. Thus, the three group title is unsuitable. As shown above, plants can reach extremely large sizes so the second title is unsuitable too.

All multicellular organisms contain specialized tissues, not only plants. Plants use active transport too and do not rely solely on diffusion. The last tile is also unsuitable as some plants do have true stems and leaves.
