Which of the following trait shows transmission from carrier female to male progeny?

Options:
A Autosomal dominant
B X-linked recessive
C Y-linked recessive
D X-linked dominant

The correct answer is:
X-linked recessive

Solution:
In humans, inheritance of X-linked recessive traits follows a unique pattern made up of three points. The first is that affected fathers cannot pass X-linked recessive traits to their sons because fathers give Y chromosomes to their sons. This means that males affected by an X-linked recessive disorder that is inherited will be from X chromosome of their mothers. Second, X-linked recessive traits are more commonly expressed in males than females.

Which of the following type of joint does not allow any movement?

Options:
A Shoulder joint
B Joint between parietal bone and temporal bone.
C Joint in between carpals
D Joint between sternum and ribs

The correct answer is:
Joint between parietal bone and temporal bone.

On the basis of extent of movement possible at the joints, these are of three types : Immovable joints, slightly movable joints and freely movable joints. Immovable joints are known as fixed or Synarthroses (Syn meaning fusion and arthroses are joints) or fibrous joints as the bone ends are fused by means of fibrous tissue. These joints are seen in cranium in the form of zig-zag structures known as sutures that joint different cranial bones. E.g. between cranial bones.

Which of the following types of plastid does not contain stored food material?

Options:
A Chromoplasts
B Elaioplasts
C Alcuroplasts
D Amyloplasts

The correct answer is:
Chromoplasts

Solution:
Chromoplasts are yellow or reddish in colour because of the presence of carotenoid pigments. They do not contain stored food material. Chromoplast are formed either from leucoplast or chloroplast.
Related Theory
Chromoplasts are the plastids which are yellow or reddish in colour because of the presence of fat-soluble carotenoid pigments. Chlorophylls are absent in these plastids. Depending upon the dominant pigments present in plastids, chromoplasts are further classified into rhodoplasts that are rich in red pigment; phaeoplasts and xanthoplasts that contain yellow pigments. Chromoplasts are formed either from leucoplasts or chloroplasts. Change of colour from green to reddish during the ripening of many fruits, for example, Tomato and Chilli, is due to transformation of chloroplasts to chromoplasts. The chromoplasts also provide colour to many fruits and flowers.

Which of the following undergoes nucleophilic substitution exclusively by $\mathrm{S}_{\mathrm{N}} 1$ mechanism?

Options:
A Ethyl chloride
B Isopropyl chloride
C Chlorobenzene
D Benzyl chloride

The correct answer is:
Benzyl chloride

Solution:
More stable the carbocation, more the tendency to undergo $\mathrm{S}_{\mathrm{N}} 1$ reaction. Thus, order of carbocation to undergo $\mathrm{S}_{\mathrm{N}} 1$ reaction is:
Benzyl $>$ Allyl $>3^{\circ}>2^{\circ}>1^{\circ}>-\mathrm{CH}_3$
Related Theory
The rate of reaction depends on the concentration of the substrate in $S_N$ l reaction While In $S_N$, the rate of reaction depends on the concentration of both the substrate and the nucleophile.
! Caution
Benzyl carbocation is stabilised by resonance so it will undergo $S_N$ I reaction.

Which of the following unicellular organism has a macronucleus for trophic function and one or more micronuclei for reproduction?

Options:
A Euglena
B Amoeba
C Paramecium
D Trypanosoma.

The correct answer is:
Paramecium

Solution:
Paramecia have two kinds of nuclei: a small nucleus germinal nucleus also known as the micronucleus is involved in sexual processes. large ellipsoidal somatic nucleus, also known as the macro-nucleus participates in the process of transcription and ensures the expression of genetic information needed for the everyday functioning of the cell.
Related Theory
Paramecium belongs to the phylum Ciliophora. Its whole body is covered with small hair-like filaments called cilia which are in constant motion and help it move with a speed that is four times its body's length per second. Just as the organism moves forward, rotating around its own axis, this further helps it to push the food into the gullet. By reversing the motion of cilia, paramecium can move in the reverse direction.

Which of the following virus is used for the purpose of organic farming?

Options:
A Baculovirus
B Influenza
C Tobacco mosaic virus
D Retrovirus

The correct answer is:
Baculovirus

Solution:
Importance in organic farming
The use of the chemical fertilizers to meet the ever-increasing demand of agricultural produces has contributed significantly to this pollution. The chemical fertilisers are being overused, and there is a growing insistence to switch to organic farming and use bio-fertilisers.
Some bacteria fix atmospheric nitrogen into organic form, which is used by the plant as a nutrient. Other bacteria can fix atmospheric nitrogen while free-living in the soil, such as Azospirillum and Azotobacter.
Baculoviruses are pathogens that attack insects and other arthropods. The majority of baculoviruses used as biological control agents are from the genus Nucleopolyhedrovirus. These viruses are excellent candidates for species-specific, narrow spectrum insecticidal applications. They have been shown to have no negative impacts on plants, mammals, birds, dishes or even non-target insects. This is especially desirable when beneficial insects are being conserved to aid in an overall integrated pest management programme or when an ecologically sensitive area is being treated.
