Answer:
Changes in genetic makeup occurs with the passage of time.
Explanation:
Antibiotic cause mutation in the bacteria which allowed to develop resistance in the bacteria. This resistance and change in the genetic makeup obeys the theory of evolution which states that all species are changed gradually with the passage of time. The genetic makeup of bacteria also changes with the passage of time and attain resistance due to regular application of antibiotics so due to this resistance, the antibiotic can't work on the bacteria.

Q.3. Describe the structure of the internal and middle ear.
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.

Please help to solve this question.
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.

Look at the graph...What is the optimal temperature for this enzyme?
A. 60 degrees C
B. 45 degrees C
C. 15 degrees C
D. 35 degrees C
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.
What is optimum temperature?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.

What is the most important biological molecule that provides energy for most cellular
processes?
What evidence is there that the 15 species of finch all evolved from one common ancestor?
All of them evolved from one rooted species, which colonized the islands only a few million years ago. This process, whereby species evolve rapidly to exploit empty eco-space, is known as adaptive radiation.
What is evidence of common ancestry and how do they explain evolution?Homologous structures provide proof for a common origin, while analogous structures show that similar selective pressures can produce similar adaptations. Alikenesses and differences among biological molecules can be used to determine species' relatedness.
Thus, adaptive radiation is one of the reasons.
