When you first hear a sound, it travels to the auricle (which is also known as the pinnae). That is the part of the ear you can see you the human eye. It then moves through the ear canal, until it reached the tympanic membrane (also known as the eardrum). When it reaches the ear drum the noise starts to vibrate. Than alerting the three tiny bones within your inner ear called the ossicles. These bones have names of course. they are called the malleus (which is known as the hammer), incus (which is known as the anvil) and stirrup (which is known as the stapes). When the ossicles moves the fluid in the cochlea, the tiny hair that is in our ears (I know gross right) then lets the brain know. The process seems long, but happens so quickly within our body.

What would be the physical sign that a bone cannot continue longitudinal growth?
faltersainse [42]

Answer:

c) The presence of an ephiphyseal line

Explanation:

The options should be:

a) the presence of osteoblasts

b) the presence of osteons

c) The presence of an ephiphyseal line

d) the presence of hyaline cartilage on the ends of the bone

Explanation:

In vertebrates, the epiphyseal line is formed once the bone is completely grown. This occurs inside a plate known as the epiphyseal plate.

From the age of 18 to 21, the bone stops growing and the cartilage inside this plate gets replaced by bone. However, bones can keep growing in width until we are approximately 25 years old.

Therefore, the physical sign that indicates that a bone cannot continue longitudinal growth would be the presence of an ephiphyseal line.

What conclusions can be drawn about the existence of carbon-12, carbon-13, and carbon-14? A) These are forms of carbon and they
Kryger [21]

Answer:

C.

Explanation:

All these carbon atoms are isotopes: they have the same amount of protons (in this case, 6 because carbon always has 6 protons) and the same amount of electrons (6 because the carbons given have a neutral charge).

Therefore, the only thing we are changing is the atomic mass and the amount of neutrons present in each isotope.

In Carbon-12, there are 6 protons, 6 neutrons, and 6 electrons.

In Carbon-13, there are 6 protons, 7 neutrons, and 6 electrons.

In Carbon-14, there are 6 protons, 8 neutrons, and 6 electrons.

If the concentration of salt in the fluid surrounding cells decreases and the concentration of other solutes remains constant?
svetoff [14.1K]

Answer:

The cell will swell.

Explanation:

The cells react distinctly when placed in different solutions like hypertonic, isotonic and hypotonic solutions. In the mentioned question, that is, in the fluid surrounding the cells, the concentration of salt reduces, which makes the solution hypotonic. Hypotonic solution exhibit high water potential and low solute concentration.  

This makes the water move from the hypotonic solution to the inside of the cell as the osmotic movement occurs from high solvent concentration to low solvent concentration, thus, swelling of the cell takes place.
