Select the CORRECT statement about the pharynx. A. The palatine tonsils are embedded in the lateral walls of the nasopharynx.
B. The pharynx contains the vocal cords.
C. The pharyngeal tonsil is located in the laryngopharynx.
D. The auditory tube drains into the nasopharynx.

Answers

Answer:

D. The auditory tube drains into the nasopharynx.

Explanation:

The auditory tubes, commonly known as eustachian tubes have their pharyngeal openings in the lateral wall of the nasopharynx. Auditory tubes also prevent the mucus to enter the middle ear by channelizing it into the nasopharynx. This clearance of mucus does not allow any infection to spread to the middle ear.

Final answer:

The correct statement about the pharynx is that the auditory tube drains into the nasopharynx.

Explanation:

The correct statement about the pharynx is D. The auditory tube drains into the nasopharynx.

The palatine tonsils are actually embedded in the lateral walls of the oropharynx, not the nasopharynx. The pharynx contains the larynx, not the vocal cords. And the pharyngeal tonsil is located in the nasopharynx, not the laryngopharynx.

Baker's yeast is a single-celled ascomycete that is used in bread making. Why does yeast make bread dough rise?

Answers

Answer:

Air cells of dough are filled with CO2.

Explanation:

Flour, water and yeast are important parts of bread dough. When we mix these the yeast enzyme will breakdown the satarch into simple sugars and metabolize the sugars to produce CO2 and ethyl alcohol into the existing air bubbles in dough.

Fermentation helps in producing the strong and elastin gluten to held the CO2 within the bubbles and inflate it. The more the air cell filled the more will be the bread dough rise.

Answer:

Presence of CO2 in the dough.

Explanation:

Yeast cells thrive on simple sugars. As the sugars are metabolized, carbon dioxide and alcohol.

chemical process known as fermentation.

Equation of Fermentation reaction:

C6H12O6(s) --> 2C2H5OH(aq) + 2CO2(g)

Tiny air cells fill with carbon dioxide are released into the bread dough, making it rise.

10 differences between animal cells and plant cells

Answers

Answer:

Following are the difference to the given question:

Explanation:

Plant cells have a wall of a cell, while cells of animals wouldn't. Cell membranes offer plants support and shape.
Chloroplasts in plant cells do not occur, however, in animal cells. Chloroplasts allow plants can grow things via photosynthesizing.
Plant cells typically get a vacuole(s) that is one or even more big, whereas animal cells are vacuous, whether any.
Large vesicles assist shape the plant and enable food and water to be store for future use.
In animal cells, the storing function takes a smaller part and the vacuoles, therefore, are smaller.
A plant cell is square in its structural way and an animal cell is often spherical and irregular.
The cell of a plant has a vesicle in its big form which is significantly smaller than the plant cell, as well as the animal cell was the or more vacuoles. In general, a vacuole is a storage area for the cells to store water.
There is no chloroplast inside the animal cell. Chloroplast is a plant cell that produces photosynthesis from its food. The plants have a green color.
The nucleus is located throughout the cell of the plant on the other edge of the peripheral cytoplasm, while the nucleus is in the animal's core.
Plant cells store food of starch while animal cells store food of glucose.
The mitochondria in the plant are fewer and also have tube cristae, whereas the animal cells have grown in various.

How can an octopus be able to fit its entire body into any space it finds regardless of its size

Answers

Octopus are invertebrates hence, they obviously lack spinal column and other major bones that forms the structure of their body, and that said they only compose more of muscles that can contract and expand which makes them able to move from space to space with ease regardless of size and position. Their bodies adapt to such change but only for a durationed time.
