SECTION B: QUESTION 2 2.1 The diagram below shows part of the human ear. 2.1.1 2.1.2 2.1.3 2.1.4 E A B C Explain the consequence if structure E lost its flexibility. Describe the process of hearing. D 2.Z Identify structures A and B Give the LETTER and the NAME of the parts that: (a) equalises pressure on both sides of the tympanic membrane (b) absorbs excess pressure waves from the inner ear (2) (2) (2) (2) (7) (15)
If structure E (stapes) lost flexibility, it would impair sound transmission, leading to hearing sensitivity.
Process of hearing: Sound waves enter the ear, vibrate the eardrum (tympanic membrane). Ossicles (A: malleus, B: incus) amplify vibrations to inner ear. Vibration of fluid in cochlea stimulates hair cells, converting to electrical signals for interpretation.
Structure A: Malleus
Structure B: Incus
(a) Structure C (eustachian tube) equalizes pressure on both sides of the tympanic membrane.
(b) Structure D (round window) absorbs excess pressure waves from the inner ear.
If structure E, which is the ossicles (specifically the malleus, incus, and stapes), lost its flexibility, it would have a significant consequence on hearing. The ossicles play a crucial role in the process of sound transmission. They amplify sound vibrations that enter the ear through the outer ear and transfer them to the inner ear. The flexibility of the ossicles allows them to vibrate in response to sound waves, transmitting these vibrations to the fluid-filled cochlea in the inner ear.If structure E lost its flexibility, the transmission of sound vibrations would be impaired. This would result in a reduced ability to perceive and interpret sound. Hearing sensitivity would be significantly compromised, and sounds may appear muffled or distorted. It may become challenging to distinguish different pitches or understand speech clearly.The process of hearing involves several steps. When sound waves enter the outer ear, they travel through the ear canal and reach the eardrum (tympanic membrane). The vibrations of the eardrum are then transferred to the ossicles (structures A and B in the diagram), which amplify and transmit the vibrations to the cochlea (structure C). The cochlea is responsible for converting the mechanical vibrations into electrical signals that can be interpreted by the brain. These signals are then sent to the brain via the auditory nerve, where they are processed and perceived as sound.Structure A, known as the Eustachian tube, equalizes pressure on both sides of the tympanic membrane. It connects the middle ear to the back of the throat, allowing air to flow in and out, maintaining equal pressure on both sides of the eardrum.Structure B, called the round window, acts as a pressure relief valve. It absorbs excess pressure waves from the inner ear, preventing damage to delicate structures by allowing fluid in the cochlea to move in response to the sound vibrations.Overall, the ear is a complex and intricate system that relies on the interaction of various structures to enable the sense of hearing.For more such questions on Hearing sensitivity:

Hearing involves a process of sound wave transduction through the tympanic membrane and ossicles. If the tympanic membrane (E) loses its flexibility, sound quality may diminish. The Eustachian tube and cochlea serve to manage pressure within the ear.
Explanation:The process of hearing (audition) involves the transduction of sound waves into a neural signal. When the tympanic membrane (structure E in your diagram), or eardrum, is struck by sound waves, it vibrates. These vibrations are then transferred to the ossicles, which are three small bones in the middle ear. The ossicles are identified as structures A (Malleus or Hammer) and B (Incus or Anvil) in your diagram. Sound waves are finally transduced into a neural signal in the inner ear.
If the tympanic membrane was to lose its flexibility, it would not vibrate as effectively when struck by sound waves. This could diminish the quality of sound and potentially lead to hearing loss.
The Eustachian tube equilibrates air pressure on both sides of the tympanic membrane. This would be your answer to part (a) of the lettered question. Part (b) refers to the role of the cochlea in the inner ear, which helps to absorb excess pressure waves from the inner ear.

according to the film on race, mitochondrial dna provides genetic information from which set of a person's ancestor(s)?
According to the film on race, mitochondrial DNA (mtDNA) provides genetic information from a person's maternal ancestors.
Mitochondrial DNA (mtDNA) is a small, circular DNA molecule found in the mitochondria of cells. Mitochondria are organelles within cells that are responsible for generating energy through a process called cellular respiration. Mitochondrial DNA contains genetic information that is distinct from the DNA in the cell's nucleus and is inherited only from the mother.
According to the race movie, a person's maternal heritage can be determined genetically by looking at their mitochondrial DNA. This is because mitochondria, the organelles that house mitochondrial DNA, are primarily inherited from the mother during fertilization. Therefore, mitochondrial DNA is passed down from generation to generation along the maternal lineage and provides information about the maternal ancestry of a person.

What was the climate like prior to the extinction ?
Answer:
The extinction you are referring to is unclear, as there have been several mass extinctions throughout Earth's history. However, it is generally accepted that climate has played a significant role in many of these events. Prior to some of the mass extinctions, such as the Permian-Triassic extinction and the Cretaceous-Paleogene extinction, the climate was warm and tropical with high levels of carbon dioxide in the atmosphere. This warm climate was likely a contributing factor to the extinction, as it may have led to changes in sea level, ocean circulation, and weather patterns that disrupted ecosystems and caused widespread extinction of species. However, it is important to note that climate is just one of many factors that can contribute to mass extinction events, and there are often multiple causes involved.

Turn the amplitude down to almost zero and wait for the waves to hit the screen. Why does the screen darken?
When I reduce the amplitude almost to zero and wait for the waves to hit the screen, my screen darkens because it takes longer for the waves to arrive.
What effect does amplitude have on color?The intensity of the color is determined by the amplitude, or the distance between the wave's midpoint and its peak. The more intense and bright the color, the greater the amplitude of the waveform.
Why doesn't changing the amplitude change the color of the light?If you change the frequency of the light, the color changes, but what if you change the amplitude You simply cannot. Photons make up light. All photons with the same wavelength (color) have the same wavelength.

The lysosome is the site of synthesis of various large biological molecules.
False. The lysosome is the site of synthesis of various large biological molecules.
Why is the above statement false?The creation of a number of major biological compounds does not take place in the lysosome. Instead, it is an organelle that may degrade and recycle a variety of macromolecules, including proteins, nucleic acids, lipids, and carbohydrates. It is a component of animal cells. Proton pumps that actively transport hydrogen ions into the lysosome maintain the acidic environment necessary for these enzymes to function at their best. Although the lysosome does not participate in the production of new molecules, it is essential for maintaining cellular homeostasis and reducing the buildup of waste products since it breaks down and recycles molecules.

Do you think an advanced civilizations may exist in the universe? Why or why not?
Answer:
Many other planets throughout the universe probably hosted intelligent life long before Earth did, a new study suggests.
The probability of a civilization developing on a potentially habitable alien planet would have to be less than one in 10 billion trillion — or one part in 10 to the 22nd power — for humanity to be the first technologically advanced species the cosmos has ever known, according to the study.
"To me, this implies that other intelligent, technology-producing species very likely have evolved before us," said lead author Adam Frank, a professor of physics and astronomy at the University of Rochester in New York. [13 Ways to Hunt Intelligent Alien Life]
In 1961, astronomer Frank Drake devised a formula to estimate the number of extraterrestrial civilizations that may exist today in the Milky Way.
Adam Frank and co-author Woodruff Sullivan of the University of Washington were interested in the odds that intelligent aliens have ever existed anywhere in the universe. So they tweaked the famous Drake equation, coming up with an "archaeological version" that doesn't take into account how long alien civilizations may last.
Frank and Sullivan also incorporated observations from NASA's Kepler space telescope and other instruments, which suggest that about 20 percent of all stars host planets in the life-friendly, "habitable zone," where liquid water could exist on a world's surface.

The building is being help up by cells, how?
The smallest unit of life, cells serve as the basic building blocks for all living things. Living organisms' growth, development, and functionality are all governed by their cells.
How cells are crucial in the building blocks of all living organisms?They may carry out a range of tasks because they are made up of several organelles, including the nucleus, mitochondria, endoplasmic reticulum, the Golgi apparatus, and other parts. The synthesis of proteins and other molecules necessary for the operation of the organism, as well as the creation of energy and the storage of nutrients, all take place within the cells. Moreover, cells enable communication between various components of the organism, allowing it to react to its surroundings.
Why do mitochondria exist?Eukaryotic cells contain organelles called mitochondria, which are the sites of cellular respiration and generate ATP as a type of energy. Mitochondria are organelles found in the cells of eukaryotes, which are organisms whose cells contain a nucleus and other organelles surrounded by a membrane. Mitochondria are the powerhouses of the cell, responsible for producing energy in the form of adenosine triphosphate (ATP). They do this through a process called cellular respiration, in which glucose is broken down with oxygen to produce ATP. ATP is then used to power a variety of cellular processes such as muscle contraction, protein synthesis, and cell signaling. In addition to producing energy, mitochondria also play a role in other cellular processes such as calcium signaling, apoptosis, and cell metabolism.

Abundance of the different bases in the human genome. Results on the human genome published in Science (Science 291:1304-1350 [2001]) indicate that the haploid human genome consists of 2.91 gigabase pairs (2.91 x 109 base pairs) and that 27% of the bases in human DNA are A. Calculate the number of A, T, G, and C residues in a typical human cell.
Answer:
A typical Human Cells=\(3.1428*10^9\) residues.
T typical Human Cells=\(3.1428*10^9\) residues.
G typical Human cells=\(2.6772*10^{9}\) residues.
C typical Human cells=\(2.6772*10^{9}\) residues.
Explanation:
Given:
Number of human genome in pairs=2.91*10^9 base pair
Number of Human genome single bases=\(2*2.91*10^{9} =5.82*10^{9}\) bases
We know that human genome are diploid, Total Human genomes will bases will be \(2* 5.82*10^{9}=1.164*10^{10}\) bases
Since A is 27%:
A typical Human cells=\(0.27*1.164*10^{10}\)
A typical Human Cells=\(3.1428*10^9\) residues.
The Number of T and A residues are same in human genome. So,
T typical Human cells=\(3.1428*10^9\) residues.
Since A and T combined form 54% of human genome then G and C form 46% combined and 23% each.
G typical Human cells=\(0.23*1.164*10^{10}\)
G typical Human cells=\(2.6772*10^{9}\) residues.
The Number of G and C residues are same in human genome. So,
C typical Human cells=\(2.6772*10^{9}\) residues.
