Indicate whether the given structure is located in the outer, middle, or inner ear. pharngotympanic tube helicotrema stapedius
Answer:
The pharngotympanic tube is in the middle ear.The helicotrema is in the inner ear.The stapedius is in the middle ear.Explanation:
The ear has three main parts, the outer part, the middle part, and the inner part. The outer part of the ear starts in the auricle, then it continues with the auditory canal, and it finishes with the eardrum. Then we have the middle ear that is separated from the outer one with the eardrum. In this section, it is the pharngotympanic tube, also known as the Eustachian tube. It is a tube that connects the inner ear with the pharynx to regulate internal pressure.
The inner ear has the bony labyrinth and the membranous labyrinth. In this part of the ear, the mechanical signals are transformed into electrical signals. The bony labyrinth has the cochlea, the vestibule, and the semicircular canals. The helicotrema is in the cochlea, and it connects the tympanic duct with the vestibular duct.
The stapedius is a muscle located in the middle ear. Its insertion is in the stapes, a small bone that moves with the vibrations that come from the eardrum to the malleus and the stapes. The stapedius' function is to protect our hearing by reducing the vibrations that enter this part of the ear.

depending on where you are on Earth.
A.) The Stratosphere
B.) The Exosphere
C.) The Mesosphere
D.) The troposphere
Answer: d
Explanation: The atmosphere has 4 layers: the troposphere that we live in near the surface of the earth; the stratosphere that houses the ozone layer; the mesosphere, a colder and lower density layer with about 0.1% of the atmosphere; and the thermosphere, the top layer, where the air is hot but very thin.
5. In 1928, Alexander Fleming noticed that a mysterious blue-green fungus had grown on some bacterial colonies that were known to cause strep throat. Upon closer inspection, he noticed that the bacterial colonies did not survive when introduced to the fungus. He questioned if something in the fungus stopped the bacteria from growing. Which steps in the scientific method are included in this story
Answer:
The steps that can be seen in this story are observation and the questioning phase, which can also be called elaboration of the problem.
Explanation:
The scientific method is a set of phases that are able to guide researchers to the creation of scientific knowledge, through an experiment. This method is essential for conducting scientific research, allowing an experiment to be managed in a way that promotes answers to scientists' questions. The scientific method presents the phases called observation, questioning (or elaboration of the problem), elaboration of hypotheses, experimentation, analysis of the results and conclusion.
In the story shown in the question above, we can see the phases called observation and questioning. The observation takes place the moment Fleming noticed a fungus capable of growing on colonies of bacteria that cause throat infections, killing them. This observation made him enter the questioning phase, when he wondered if the fungus was able to prevent the growth of these bacteria.
Which of the following is a difference between arteries and viens?
arteries carry blood and veins carry only plasma
arteries do not have valves and veins do have valves
arteries are thin and veins are thick
arteries carry blood back to the heart and veins carry blood to the heart
The correct option is :
=》arteries do not have valves and veins do have valves.
Arteries don't have valves because back flow of blood isn't possible due to high pressure, but blood in veins doesn't have high pressure just like arteries, so to stop backflow of blood, veins have valves.

What is the answer to this question if anybody knows i’m really finding it confusing
A species of moth lived in a forest with a mixture of dark- and light-colored trees. The coloring of these moths is inherited. The dark moths were hidden from predators on the dark trees, and the light moths were hidden on the light trees.
When the light-colored trees were killed by a disease, the forest was suddenly made up almost entirely of dark trees. Generations later, almost all the moths had the dark coloring. Which of the following gives a correct explanation?
Answer: The light moths that survived did not mate and have offspring because they thought that their offspring would easily be seen and eaten by predators.
The light moths that survived had dark offspring because the change in the environment caused the parents to decide to have offspring that would do better in the changed environment.
The light moths saw that the dark moths were less likely to be eaten by predators, so they made themselves dark as well.
The dark moths were better hidden from predators, so more of them survived. Because dark parents outnumbered light parents, there were many more dark offspring than light offspring in the next generation.
