A.
Paramecium
B.
Tiypanosoma
C.
Monocystis
D.
Plasmodium
Ans:
Paramecium
Explanation :
“Animalcule” is a old term for a microorganism; it just means “small animal”. A paramecium is shaped somewhat like a slipper (a soft shoe), so it is called the slipper animalcule. Other better-known animalcules include: Amoeba, called Proteus animalcule; Noctiluca scintillans, commonly called the ‘Sea Sparkles’; Rotifers, called wheel animalcules, etc.
[9] The thymus gland produces a hormone called -
A.
thyroxine
B.
thymosin
C.
thyronine
D.
calcitonin
Ans:
thymosin
Explanation :
The thymus is a specialized primary lymphoid organ of the immune system. Thymosin hormones are typically produced by the thymus gland and trigger the creation of T-cells, which are used by the immune system to fight disease. The thymus gland is only active until puberty.
[10] Blood group AB has -
A.
No antigen
B.
No antibody
C.
Neither antigen nor antibody
D.
Both antigen and antibody
Ans:
No antibody
Explanation :
Blood group AB individuals have Both (1) and (2) antigens on the surface of their RBCs, and their blood plasma does not contain any antibodies against either A or B antigen. Therefore, an individual with type AB blood can receive blood from any group (with AB being preferable), but cannot donate blood to any group other than AB. They are known as universal recipients.
[11] What does the word 'amphibian' means?
A.
Three lives
B.
Four lives
C.
Two lives
D.
One lives
Ans:
Two lives
Explanation :
The word amphibian means two-lives. Amphibians spend their lives in the water and on land. All amphibians begin their life in water with gills and tails; as they grow, they develop lungs and legs for their life on land. Members of this animal class are frogs, toads, etc.

constricts blood vessels
D.
stimulates lactation
Ans:
decreases blood sugar
Explanation :
Insulin is central to regulating carbohydrate and fat metabolism in the body. It stops the use of fat as an energy source by inhibiting the release of glucagon. It removes excess glucose from the blood, which otherwise would be toxic.
[16] When we touch leaves of 'Touch me not plant", they close, these movements are called -
A.
Photonastic movements
B.
nyctinastic movements
C.
seismonastic movements
D.
chemonastric movements
Ans:
seismonastic movements
Explanation :
These types of movements have been termed seismonastic movements. The movement occurs when specific regions of cells lose turgor pressure, which is the force that is applied onto the cell wall by water within the cell vacuoles and other cell contents.
[17] The concept of tissue culture was introduced by -
A.
Halfmeister
B.
Hanstein
C.
Haberlandt
D.
Harming
Ans:
Haberlandt
Explanation :
Wilhelm Roux is credited with the establishment of the basic principle of tissue culture in 1885. However, it was Gottlieb Haberlandt, an Austrian botanist, who first pointed out the possibilities of the culture of isolated tissues, plant tissue culture.
[18] What accumulates in the muscles after continuous strenuous physical exercise as a result of temporary anaerobic respiration that causes muscular fatigue?
A.
ATP
B.
Lactic acid
C.
Ethyl alcohol
D.
Carbon dioxide
Ans:
Lactic acid
Explanation :
Anaerobic reactions break down glucose into pyruvic acid, which then reacts to produce lactic acid. As muscle metabolism shifts from aerobic to anaerobic ATP production, lactic acid begins to accumulate in muscles and to appear in the bloodstream. This leads to muscle fatigue.
[19] Thalassemia is an example of -
A.
Deletion mutation
B.
Point mutation
C.
Silent mutation
D.
Frame shift mutation
Ans:
Frame shift mutation
Explanation :
Frame shift mutations are associated with Thalassemia. They involve a deletion or insertion of one or two base pairs within a coding sequence of a gene. As the coding message is read in triplets codons and deletions, the reading frame of mRNA is altered resulting in a nonsense sequence of amino acids.
[20] The plant from which cocoa and chocolate are obtained is a -
A.
herb
B.
shrub
C.
small tree
D.
very big tree
Ans:
small tree
Explanation :
Chocolate production starts with harvesting cocoa in a forest. Cocoa comes from tropical evergreen Cocoa trees, such as Theobroma Cocoa which are small trees. These trees live in the understory of tropical forests and require other, taller trees to shelter them from wind and sun
[21] The biggest single-celled organism is -
A.
Yeast
B.
Acetabularia
C.
Acetobacter
D.
Amoeba
Ans:
Amoeba
Explanation :
Researchers, in October 2011, found "giant amoebas" (Xenophyophores) beneath the surface of the Pacific in the Mariana Trench. At more than four inches in length, they are the largest single-celled organism on Earth. They are found exclusively in the deep sea.
[22] Which one of the following is not a rabi crop?
A.
Mustard
B.
Rice
C.
Wheat
D.
Gram
Ans:
Rice
Explanation :
Rabi refers to agricultural crops sown in winter and harvested in the spring. Examples of Rabi Crops: Wheat, Gram, Pea, Mustard, Linseed, Barley. Rice is a Kharif crop, cultivated and harvested during the rainy (monsoon) season in the South Asia.
[23] Resin is a product of -
A.
Grapes
B.
Coniferous trees
C.
Rubber tree
D.
Banyan tree
Ans:
Coniferous trees
Explanation :
Resin in the most specific use of the term is a hydrocarbon secretion of many plants, particularly coniferous trees. It is distinct from other liquid campounds found inside plants or exuded by plants, such as sap, latex, or mucilage.
[24] Which angiosperm is vessel-less?
A.
Hydrilla
B.
Trochodendron
C.
Maize
D.
Wheat
Ans:
Hydrilla
Explanation :
Trochodendron is a genus of flowering plants with one living species. It is vesselless angiosperm. Fewer than 200 species of angiosperms have the primitive feature of vesselless wood. With two exceptions— Trochodendron and Tetracentron—, all vesselless angiosperms occur in the Magnoliidae.
[25] Who was the first child born alter operative procedure?
A.
Caesar
B.
Huxley
C.
William
D.
Pasteur
Ans:
Caesar
Explanation :
Julius Caesar is commonly believed to have been born due to operative procedure from his mother Aurelia. It is from his name that the word 'Caesarean section' is derived. It is a surgical procedure in which one or more incisions are made through a mother's abdomen and uterus to deliver baby.
Explanation :
Pulse, in botany, is a common name for members of the Fabaceae (Leguminosae), a large plant family. Pulses, high in protein, are used as food for humans and other animals. Besides, they play a key role in crop rotation due to their ability to fix nitrogen.
[14] Laws of heredity was put forward by -
A.
Mendel
B.
Mendeleev
C.
Pavlov
D.
Koch
Ans:
Mendel
Explanation :
The laws of heredity were discovered by Gregor Mendel in about 1856-1863. Mendel conducted experiments in plant hybridization, collecting the results of cross-fertilizing hundreds of edible pea plants. The results from Menders experiments confirmed his ideas about heredity: the law of segregation, which has become known as Mendel's First Law, and the law of independent assortment, also known as Mendel's Second Law.
