Distinguish between : Electrical and chemical synapses:
✓

Answer

Electrical synapse Chemical synapse
1. The gap between the successive neurons in electrical synapse is very less [3.8 nm],1. The gap between two successive neurons in chemical synapse is larger than electrical synapse [10-20 nm].
2. Transmission across the gap is faster in electrical synapse.2. Transmission across the gap in chemical synapse is relatively slower than electrical synapse.
3. Electrical synapse is less common.3. Chemical synapse is more common.
4. Electrical synapse is found in those places of the body requiring instant response.4. Chemical synapse is found almost everywhere and connects neuron to neuron, muscles or glands.

Read the following and answer any four questions from (i) to (v) given below:
Aditya went to his hometown located in countryside along with his parents during his summer vacations. His grand parents' house is surrounded by farmland from all sides. Lots of crops were growing nearby and Aditya was very excited to visit the crop fields.

Read the following and answer any four questions from (i) to (v) given below:
During a study of inheritance of two genes, teacher asked students to perform an experiment. The students crossed white eyed, yellow bodied female Drosophila with a red eyed, brown bodied male Drosophila (i.e., wild). They observed that progenies in $F_2$ generation had 1.3 percent recombinants and 98.7 percent parental type combinations. The experimental cross with results is shown in the given figure. [Note: Dominant wild type alleles are represented with (+) sign in superscript]
  1. By conducting the given experiment, teacher can conclude that
  1. Genes for eye colour and body colour are linked
  2. Genes for eye colour and body colour show complete linkage
  3. Linked gene remain together and are inherited.
  1. A and B only
  2. B only
  3. A and C only
  4. A, Band C
  1. Teacher asked to conduct an experiment on Drosophila because.
  1. The male and female flies are easily distinguishable.
  2. It completes its life cycle in about two weeks.
  3. A single mating could produce a large number of progeny flies.
  4. All of these
  1. Genes white eyed and yellow bodied located very close to one another on the same chromosome tend to be transmitted together are called.
  1. Allelomorphs.
  2. Identical genes.
  3. Iinked genes.
  4. Recessive genes.
  1. Select the correct statement regarding the given experiment.
  1. The physical distance between two genes determines strength of linkage.
  2. The physical distance between two genes determines frequency of crossing over.
  3. The two linked genes always segregate independently of each other.
  4. Both (a) and (b)
  1. Assertion: When yellow bodied, white eyed Drosophila females were hybridised with brown-bodied, red eyed males and $F_1$ progeny was intercrossed, $F_2$ ratio deviated from 9 : 3 : 3 : 1.
Reason : When two genes in a dihybrid are on the same chromosome, the proportion of parental gene combinations are much higher than the non-parental type
  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.

Intrauterine devices are most widely accepted methods of contraception. These are used by females and are inserted by doctor or nurses in the uterus through vagina. However, these devices are not recommended for those who eventually intend to conceive.
  1. How does CuT prevent conception?
  1. Cu ions make uterus unsuitable for implantation.
  2. Cu ions make cervix hostile to the sperms.
  3. Cu ions suppress sperms motility.
  4. Cu ions inhibit ovulation.
  1. Which of the following IUDs makes uterus unsuitable for implantation?
  1. LNG-20.
  2. Multiload 375.
  3. Cu7.

  2. They increase phagocytosis of sperms within the uterus.
  3. They block entry of sperms through the cervix.
  4. Both (b) and (c).
  1. Select the correct matched pair.
  1. Hormone releasing IUD - LNG-20.
  2. Non-medicated IUD - Progestasert.
  3. Copper releasing IUD - Lippes loop.
  4. None of these.
  1. Assertion: IUDs can cause excess menstrual bleeding and pain.
Reason: IUDs can perforate uterus.
  1. Both assertion and reason are true, and reason is the correct explanation of assertion.

Read the following and answer any four questions from (i) to (v) given below:
A typical angiospermic ovule is a small structure attached to the placenta by means of a stalk called funicle. The body of the ovule fuses with funicle in the region called hilum. Each ovule has one or two protective envelopes called integuments. Integuments encircle the nucellus except at the tip where a small opening called the micropyle is formed. Mature ovules are classified on the basis of funiculus. It can be orthotropous, anadromous, hernitropous, campylotropous, etc.
  1. The body of the ovule consists of a mass of parenchymatous cells called:
  1. Integuments.
  2. Nucellus.
  3. Hilum.
  4. Funiculus.
  1. Refer to the given figure and select the correct statement regarding it.
  1. This type of ovule is found in cactus.
  2. The micropyle comes to lie close to the funiculus due to unilateral growth of ovule.
  3. It is most common type of ovule found in the members of Chenopodiaceae.
  4. It is half inverted ovule.
  1. Identify the parts labelled as A, B, C and D in the given figure and select the correct option.
S. No A B C D
(a) Chalaza Female gametophyte Embryo sac Micropyle
(b) Chalaza NuceIIus Embryo sac Micropyle
(c) Micropyle Egg Embryo sac Chalaza
(d) Micropyle Nucellus Embryo sac Chalaza
  1. Mature ovules are classified on the basis of funiculus. If micropyle lie close to the funiculus, the ovule is termed as:
