Answer:

I think the answer would be C.

Explanation:

D is wrong for obvious reasons, elimanate any silly or impossible answers.

Since poly means muliple, and single means, not muliple (in most cases), B is elimanated.

Since Grapihic usaully refers to things that can been seen, where genic ussaully refers to more so like personality characteristics.

Answer:

The inner ear has two openings into the middle ear, both covered by membranes

Explanation:

The oval window lies between the middle ear and the vestibule, whilst the round window separates the middle ear from the scala tympani (part of the cochlear duct)

❈ The internal ear —

➥ The inner ear (also called the labyrinth) contains 2 main structures — the cochlea, which is involved in hearing, and the vestibular system (consisting of the 3 semicircular canals, saccule and utricle), which is responsible for maintaining balance.

➥ The cochlea is filled with fluid and contains the organ of Corti — a structure that contains thousands of specialised sensory hair cells with projections called cilia. The vibrations transmitted from the middle ear cause tiny waves to form in the inner ear fluid, which make the cilia vibrate.

➥ The hair cells then convert these vibrations into nerve impulses, or signals, which are sent via the auditory nerve to the brain, where they are interpreted as sound. The round window (fenestra cochlea) is a membrane that connects the cochlea with the middle ear. It helps dampen the vibrations in the cochlea.

➥ The semicircular canals also contain fluid and hair cells, but these hair cells are responsible for detecting movement rather than sound. When you move your head, the fluid within the semicircular canals (which sit at right angles to each other) also moves. This fluid motion is detected by the hair cells, which then send nerve impulses about the position of your head and body to the brain to allow you to maintain your balance.

➥ The utricle and saccule work in a similar way to the semicircular canals, allowing you to sense your body’s position relative to gravity and make postural adjustments as required.

❈ The middle ear —

➥ The middle ear is an air-filled space that contains 3 tiny bones (known as ossicles), called the malleus (hammer), incus and stapes (stirrup). Sound waves that reach the tympanic membrane cause it to vibrate.

➥ This vibration is then transmitted to the ossicles, which amplify the sound and pass on the vibration to the oval window (a thin membrane between the middle and inner ear). The Eustachian tube is a narrow tube that connects your middle ear to the back of your nose and throat (known as the nasopharynx). Its function is to allow air into the middle ear as well as drain mucus from the middle ear into the nasopharynx.

➥ When you swallow, your Eustachian tube opens up to allow air into the middle ear, so that the air pressure on either side of the tympanic membrane is the same. In situations when there is a sudden change in air pressure (e.g. during take-off and landing when travelling on a plane), the pressure in the middle ear is not the same as the outside air pressure.

➥ This can make your eardrum bulge or retract and less able to transmit vibrations, causing temporary hearing problems. By swallowing or ‘popping’ your ears, you can equalise the pressure.

Look below - A plane is math related.

Explanation:

a flat surface on which a straight line joining any two points on it would wholly lie.

"the horizontal plane"

synonyms:

flat surface · level surface · the flat · horizontal

Hope this Helps!

Answer:

I Don't Know what your asking but if your trying to figure out what a plane is this might help

1.  a flat surface on which a straight line joining any two points on it would wholly lie.

2. a level of existence, thought, or development.

3. completely level or flat.

4. (of a bird or an airborne object) soar without moving the wings; glide.

Also I don't know why this would be biology related.

Answer:

B: 45 degrees C

Explanation:

However, above 40-45 degrees Celsius, enzymes are usually denatured and can no longer catalyse the reaction, because the hydrogen bonds are broken, so the enzyme permanently loses its shape. The temperature at which the reaction rate is fastest is the optimum temperature.

As per the graph, the optimum temperature for the enzyme is 45 degree Celsius. The correct option is C.

The temperature at which the enzyme exhibits the greatest activity is referred to as the optimum temperature.

Enzyme activity decreases as the temperature rises or falls. It can even become inactive at times. It is equivalent to the body temperature of a warm-blooded animal.

The kinetic energy in the substrate and enzyme molecules is optimal for the maximum number of collisions at the optimal temperature.

At high temperatures, the enzyme's shape changes, and it no longer complements its specific substrate.

It is the temperature at which the enzyme's reaction rate is fastest. It will be the point on the graph where the line reaches a peak at 45 degrees Celsius.

Thus, the correct option is C.

Answer:

Los tejidos están formados por la unión de células relacionadas. Las células de un tejido no son idénticas pero trabajan juntas para desarrollar funciones específicas.

Answer:

a. Glycolysis

b. actually, both plants and animals use glycolysis. They use these during cellular respiration and plant respiration

c. Heart tissue!

Explanation:

a.  Glycolysis produces 2 ATP per glucose molecule, and thus provides a direct means of producing energy in the absence of oxygen. Lactic acid, the end product of anaerobic glycolysis.

b. In organisms that perform cellular respiration, glycolysis is the first stage of this process. In plants, this metabolic process occurs in the cytosol and plastids of both photosynthetic and non-photosynthetic organs.

c. Pyruvate is an important chemical compound in biochemistry. It is the output of the metabolism of glucose known as glycolysis. In highly oxidative tissue, such as the heart, the production of pyruvate is essential for acetyl-CoA synthesis and L-malate synthesis.

Answer: The movement of continents changes wind patterns and ocean currents.

hope this helps!

Explanation:

The best statement that describe the effect of tectonic activity on climate change is that the movement of continents changes wind patterns and ocean currents.

Tectonic activities includes volcanoes, mountain building, earthquakes and many more.

Tectonic activities are common in plate boundaries where plates converge, diverge or transform.

As a result of the movement of these continental plate, tectonic activities occurs causing earth climate change

Therefore, the movement of this oceanic or continental plates changes the wind pattern and ocean current.
