Read the following and answer any four questions from (i) to (v) given below:
Reerna, Jai and Ankit are suffering from autoimmune diseases of adrenal cortex, joints and thyroid gland, respectively. Their immune system failed to recognise self and non-self and started destroying their body's own proteins. They are seeking proper medical help for their conditions but their condition cannot be cured completely.
Based on the above information, answer the following questions.
  1. Select the option that correctly identifies autoimmune diseases of Reema, Jai and Ankit.
S no.
Reema
Jai
Ankit
(a)
Diabetes
Grave's disease
Rheumatic fever
(b)

Multiple sclerosis
Myasthenia gravis
(c)
Addison's disease
Rheumatoid arthritis
Hashismoto's thyroiditis
(d)
Systemic lupus erythematosus
Severe combined immunodeficiency disease
AIDS
  1. Reema's autoimmune condition is characterised by
  1. Undersecretion of insulin.
  2. Destruction of RB Cs and low RB C count.
  3. Undersecretion of adrenal cortex hormones.
  4. Low production of intrinsic factor required for absorption of $B_12$
  1. What do you think is the major cause of Jai's condition?
  1. Deterioration of myelin sheath around nerve cells, leading to loss of precise muscle control
  2. Destruction of heart cells, leading to weakening of entire heart wall.
  3. Destruction of beta cells, leading to undersecretion of insulin.
  4. Deposition of immune complexes of IgM, IgG and complement in joints thereby inflaming joints, destroying articular cartilage and fusing bones.
  1. How do you think Ankit's condition got diagnosed?
  1. Low level of thyroid hormone and elevated levels of TSH in Ankit's blood.
  2. Presence of antibodies against thyroid pen oxidase (TPO antibodies) in Ankit's blood.
  3. Elevated erythrocyte sedimentation rate (ESR), reduced C-reactive protein (CRP) in Ankit.
  4. Both (a) and (b)
  1. Assertion: Immunosuppressive drugs often reduce the severity of autoimmune disorders.
Reason: Monoclonal antibodies have been successfully used in the treatment of autoimmune disease.
  1. Both assertion and reason are true, and reason is the correct explanation of assertion.
  2. Both assertion and reason are true, but reason is not the correct explanation of assertion.
  3. Assertion is true, but reason is false.
  4. Both assertion and reason are false.

Read the following and answer any four questions from (i) to (v) given below:
Non-native or alien species are often introduced in advertently for their economic and other uses. They often become invasive and drive away the local species. Exotic species have proved harmful to both aquatic and terrestrial ecosystems. For example, water hyacinth (Eichhornia crassipes) was introduced in Indian waters to reduce pollution. It was clogged water bodies including wetlands at many places resulting in death of several aquatic plants and animals.
  1. Island water ecosystem are the most vulnerable due to:
  1. Small size.
  2. Small number of species.
  3. Increases reproductive capacity.
  4. Both (a) and (b).
  1. Which of the following is not an alien species?
  1. Lantana camara.
  2. Periplaneta americana.
  3. Nile Perch.
  4. Yucca moth.
  1. Second major cause of species extinction is:
  1. Habitat loss and fragmentation.
  2. Over exploitation.
  3. Alien species invasion.
  4. Co-extinction.
  1. Assertion: Eichhomia crassipes drains off oxygen from water and can be seen growing in standing water.
Reason: Eichhornia crassipes is an indigenous species of India.
  1. Both assertion and reason are true and reason is the correct explanation of assertion.
  2. Both assertion and reason are true but reason is not the correct explanation of assertion.
  3. Assertion is true but reason is false.
  4. Both assertion and reason are false.
  1. The population of species Pin a certain conununity was constant until a population species Q from a distant land was subsequently introduced into that community. The interaction between the two populations is reflected in the graph below.


What could be the possible reason for the decrease in the population of species P over a number of days?
  1. Species Q is a predator of species P.
  2. Species Q is a prey species which wiped out the population of species P.
  3. Species P and Q compete for space but feeds on different food.
  4. None of these.

Read the following and answer any four questions from (i) to (v) given below:
During copulation, semen is released by the penis into the vagina. 'The motile sperms swim rapidly, fuse with ovum in the ampullary region, resulting in fertilisation. Haploid nucleus of sperm fuse with that of ovum to form diploid zygote.
  1. In female genital tract, sperms are made capable of fertilising the egg. This phenomenon of sperm activation is called:
  1. Amphimixis.
  2. Cortical reaction.
  3. Capacitation.
  4. Acrosomal reaction.
  1. Select the correct sequence of various physical and chemical events that take place during fertilisation.
  1. Fusion of cortical granules with plasma membrane of secondary oocyte.
  2. Formation of fertilisation cone to receive sperm.
  3. Release of sperm lysin from acrosome.
  4. Mixing up of chromosomes of a sperm and an ovum.
  1. R → Q → P → S
  2. Q → S → R → P
  3. Q → R → S → P
  4. R → P → Q → S
  1. Assertion: Only one sperm can fertilise an ovum.
Reason: The secretion of acrosome help the sperm to enter into cytoplasm of ovum through zona pellucida and plasma membrane.
  1. Both assertion and reason are true, and reason is the correct explanation of assertion.
  2. Both assertion and reason are true, but reason is not the correct explanation of assertion.
  3. Assertion is true, but reason is false.
  4. Both assertion and reason are false
  1. What is the significance of fertilisation?
  1. It restores haploid number of chromosomes.
  2. It produces offspring genetically identical to parents.
  3. It initiates cleavage.
  4. Both (b) and (c).
  1. Site of fertilisation in humans is:
  1. Endometrium of uterine cavity.
  2. Ampullary isthmic junction of oviduct.
  3. Cervix of uterus.
  4. Infundibulum of fallopian tube.
