Answers
T cells undergo a clonal expansion and differentiation followed by a contraction phase, once the pathogen has been cleared.
How does the T cell respond to a pathogen?Recent in vitro and in vivo evidence supports an antigen-pre-senting role for T cells. Human T cells exhibit major histocompatibility complex (MHC) class II antigens and adhesion molecules that are typical of antigen-presenting cells (APCs).
Controlling the populations of effector, memory, and naive T lymphocytes depends on cell survival and death. The presence of MHC proteins in the antigen-presenting cell is necessary for the identification process because they bind to these fragments, transport them to the cell surface, and present them to the T cells there together with a co-stimulatory signal.
Due to their dual specificity, T cells can distinguish between peptide antigens presented by self-MHC I or MHC II molecules and those presented by other MHC molecules.

Answers
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.

Skeleton features cladogram
Answers
The main skeletal features used to construct a cladogram include the presence or absence of specific bones/structures, bone shape/structure, dental characteristics, skeletal adaptations, and skull morphology.
Cladograms are phylogenetic trees that illustrate the evolutionary relationships between different organisms. When constructing a cladogram, various skeletal features can be used as characters to determine the branching patterns and common ancestry among organisms. Here are some main skeletal features used in cladistic analysis:
Presence or absence of specific bones or structures: The presence or absence of certain skeletal elements, such as wings or limbs, can provide insights into evolutionary relationships.
Bone shape and structure: Comparing the shapes, sizes, and structures of bones can help identify shared characteristics and infer common ancestry.
Dental characteristics: The structure and arrangement of teeth, including the type and number of teeth, can provide information about evolutionary relationships and dietary adaptations.
Skeletal adaptations: Features like the presence of a notochord, presence of a bony skeleton, or modifications for specialized locomotion (e.g., wings, fins, limbs) can be used to infer evolutionary relationships.
Skull morphology: Examination of the skull, including the shape of the cranium, presence and structure of specific cranial bones, and jaw structure, can help determine evolutionary relationships and functional adaptations.
By analyzing these skeletal features and comparing them across different organisms, cladistic analysis aims to identify shared derived characteristics (synapomorphies) that indicate common ancestry and to construct a branching pattern that represents the evolutionary relationships between the organisms being studied.

Answers
Transduction refers to the transformation of stimulus energy into neural impulses.
A virus or other viral vector introduces foreign DNA into a cell through a process known as transduction. One illustration of horizontal gene transfer is the viral transmission of DNA from one bacterium to another.
In contrast to conjugation, which involves physical contact between the cells giving and receiving DNA, transduction is DNase resistant (transformation is susceptible to DNase).
Molecular biologists frequently utilize transduction to successfully transfer a foreign gene into the genome of a host cell (both bacterial and mammalian cells).
At the University of Wisconsin-Madison, researchers Norton Zinder and Joshua Lederberg identified transduction in Salmonella in 1952.
