because the vibrations are transmitted to the inner ear after the bones amplify it
Ossicles are the body's tiniest bones. the malleus (hammer), incus (anvil), and stapes (stirrup). Ossicles amplify sound.
What are ossicles?Ossicles are very little bones; in fact, they are the tiniest bones in the entire human body. The malleus (hammer), the incus (anvil), and the stapes are the names of the three bones because of the forms they make (stirrup). The sound is amplified even further by the ossicles.
In order to reach the eardrum, sound waves must first enter the outer ear and then proceed via the ear canal, which is a very short conduit. The incoming sound waves cause the eardrum to vibrate, and the eardrum in turn transmits these vibrations to three very small bones located in the middle ear. The malleus, incus, and stapes are the names given to these three bones.
Hearing is dependent on a series of intricate steps that convert sound waves in the air into electrical impulses. These steps are necessary for hearing.

which specialized structures are unique to the cnidarians?
Explanation:
Cnidarians contain specialized cells known as cnidocytes (“stinging cells”) containing organelles called nematocysts (stingers).
Cnidarians have stinging cells which are known as cnidocytes. This is the unique feature of cnidarians.
What are cnidarians and their characteristics?The class Soft-bodied stinging creatures like corals, sea anemones, and jellyfish are categorized as Cnidaria. Nearly every ocean ecosystem contains cnidarians. They may survive in warm or cold, shallow or deep water. Freshwater is home to a few species. Cnidarians can either live alone or in colonies.
Cnidarians share a number of fundamental traits. Cnidaria is all aquatic organisms, primarily marine ones. All of them have stinging tentacles called nematocysts that they utilize to capture prey. Cnidarians have just two body layers: the ectoderm and endoderm, which are divided by a layer that resembles jelly and is known as the mesoglea.
Thus, cnidocytes are unique features of cnidarians.

The movement of water across cellular membranes through aquaporins is known as?(1 point)
endocytosis
active transport
simple diffusion
osmosis
Answer:
- osmosis -
Explanation:
The quick trick is that osmosis can only occur in water or insolvent movements!
Think of fish, fish have a lot to do with osmosis because the water will go through the fish's skin/gills which will help them breathe and thrive.
!! hope that helps love you guys !!
The movement of water across cellular membranes through aquaporins is known as osmosis. Water moves down the concentration gradient. The fourth option is the correct answer.
How do molecules move across the cell membrane?Molecules can pass the cell membrane both actively and passively. In passive transport, no energy or ATP is required. Molecules can move from a higher concentration to a lower concentration.
Diffusion and osmosis are examples of passive transports. In diffusion, gases and other small molecules pass the cell membrane from a higher to a lower concentration. Water is a polar molecule, so it doesn't pass the membrane due to its nonpolar nature. Cells have aquaporin channels that are made for water.
Through aquaporins, water passes into the cell. This is called osmosis. In active transport, energy is required. When a molecule passes from a lower concentration to a higher concentration, energy is needed. An example is sodium-potassium ATPase.
Hence, the correct answer is osmosis. The fourth option is the correct answer.

Explanation:
Interphase is the period of the cell cycle during which the cell is not dividing. The majority of cells are in interphase most of the time. Mitosis is the division of genetic material, during which the cell nucleus breaks down and two new, fully functional, nuclei are formed.

Explain why contractile vacuoles would be of little value to one-celled organisms living in the ocean (salt water)
The organisms living in an aquatic environment have to undergo osmoregulation and survive in a hypotonic environment. The organisms such as paramecium, protists, and unicellular algae have contractile vacuoles.
The functions of the contractile vacuoles include:
1. Contractile vacuoles help in the osmoregulation, such that the movement of solute particles inside and outside of the cells.
2. The contractile vacuoles are also required to remove excess water from the organisms.
3. The vacuoles contract to discharge the fluid for the survival of organisms like paramecium and algae.
Thus, the contractile vacuoles contract to allow the organisms to survive in a hypotonic environment.

The input of sewage, fertilizer runoff, and animal waste can cause the formation of Choose one: A. an algal bloom. B. nutrient-poor soil C. fertile farmland. D. an artesian well.
Answer:
An algal bloom.
Explanation:
The input of sewage, fertilizer runoff, and animal waste can cause the formation of an algal bloom (abundances of cyanobacteria) because of the excess nutrients (nitrogen or phosphorus). If there are too much nutrients in the water (caused by the sewage, fertilizer runoff, and animal waste) it creates a perfect environment for excess growth, being an algal bloom. Algal blooms are toxic and are known to be harmful to the animals that rely on this source for their survival and humans as well.

which hormone signals the breakdown of glycogen in the liver increasing glucose in the blood?
Answer:
The answer is glucagon
Explanation:
When the blood sugar level drops down, the glucagon hormone converts the glycogen into glucose and raises its level in the bloodstream.
Glycogen is a main source of energy for the body. Glycogen is stored in the liver. When the body needs more energy, certain proteins called enzymes break down glycogen into glucose. They send the glucose out into the body.
Which hormone stimulates the breakdown of glycogen in the liver into glucose?Glucagon's role in the body is to prevent blood glucose levels from dropping too low. To do this, it acts on the liver in several ways: It stimulates the conversion of stored glycogen (stored in the liver) to glucose, which can be released into the bloodstream.
How does glucagon increase blood glucose?
When your blood glucose levels trend lower or fall too low (hypoglycemia), your pancreas releases more glucagon. Glucagon helps blood glucose levels rise back up in multiple ways, including Glucagon triggers your liver to convert stored glucose (glycogen) into a usable form and then release it into your bloodstream.
