Explanation :
The removal of supernumerary cells (in excess of the required number) during development. 
• Involution of hormone-dependent tissues on hormone withdrawal, such as endometrial cell breakdown during the menstrual cycle, ovarian follicular atresia in menopause, and regression of the lactating breast after weaning.
• Cell turnover in proliferating cell populations, such as immature lymphocytes in the bone marrow and thymus, B lymphocytes in germinal centers that fail to express useful antigen receptors and epithelial cells in intestinal crypts, to maintain a constant cell number (homeostasis).
• Elimination of potentially harmful self-reactive lymphocytes to prevent immune reactions against one’s own tissues.
• Death of host cells that have served their useful purpose, such as neutrophils in an acute inflammatory response, and lymphocytes at the end of an immune response.

4. Mitochondria contains enzymes that take part in-
   a. Respiratory chain or electron transport
   b. Oxidative phosphorylation
   c. Krebs/citric acid cycle
   d. β-oxidation of fatty acid
   e. Ketogenesis

Inner mitochondrial membrane shows long infoldings called cristae (for increasing surface area).
The lipid bilayer of the inner membrane contains unusual phospholipids and is highly impermeable to ions.
Inner mitochondrial membrane is a site for oxidative phosphorylation, respiratory (electron transport) chain, and ATP synthesis.

Features of autosomal recessive disorders -
  1. ক
    Reduced penetrence
  2. খ
    Occurs in late life
  3. গ
    Disease expression is not uniform
  4. ঘ
    Both sexes are equally affected
ব্যাখ্যা
Explanation -
The expression of the defect tends to be more uniform than in autosomal dominant disorders.
• Complete penetrance is common.
• Onset is frequently early in life.
• Although new mutations associated with recessive disorders do occur, they are rarely detected clinically.
Since the individual with a new mutation is an asymptomatic heterozygote, several generations may pass before the descendants of such a person mate with other heterozygotes and produce affected offspring.
• Many of the mutated genes encode enzymes. Occurs due to defect in enzymes.

  2. খ

  3. গ

  4. ঘ
    Superior Olivary Nuclei
ব্যাখ্যা
The sequential steps are as follows:

1.The bipolar cells of the spiral ganglion, which are located in the cochlea’s modiolus, are the first-order neurons of the auditory pathway.
2. The second-order auditory pathway neurons are made up of neurons from the dorsal and ventral cochlear nuclei in the medulla oblongata.
3. Both the superior olivary nuclei and the lateral lemniscus nucleus comprise the third-order neurons.
4.The subcortical auditory centre is formed by the medial geniculate body, where the fibres of third-order neurons terminate.
5.The nerve fibres from the medial geniculate body travel as auditory radiation via the internal capsule to the temporal cortex.
6.In the midbrain, the inferior colliculus of the tectum receives some fibres from the medial geniculate body.
7.The reflex movements in response to auditory stimuli are mediated by the auditory radiation fibres.
8.The temporal lobe of the cerebral cortex houses the cortical auditory centres. The perception of auditory impulses, analysis of sound pitch and intensity, and identification of sound source are all concerns of the cortical auditory centres.
