Q.8 Epiphyte, also called air plant, any plant that grows upon ____________.
A. another plant
B. together
C. in sand
D. in water
Correct Answer) A: another plant
Description:
Epiphyte, also called air plant, any plant that grows upon another plant or object merely for physical support. Epiphytes have no attachment to the ground or other obvious nutrient source and are not parasitic on the supporting plants. Most epiphytes are found in moist tropical areas, where their ability to grow above ground level provides access to sunlight in dense shaded forests and exploits the nutrients available from leaf and other organic debris that collects high in the tree canopy.

Q.9 A substance that protects the body against cancer is:
A. inferno
B. penicillin
C. interferon
D. insulin
Correct Answer) C: interferon
Description:
Interferons are a group of signaling proteins made and released by host cells in response to the presence of several viruses. In a typical scenario, a virus-infected cell will release interferons causing nearby cells to heighten their anti-viral defenses. IFNs belong to the large class of proteins known as cytokines, molecules used for communication between cells to trigger the protective defenses of the immune system that help eradicate pathogens. Interferons are named for their ability to "interfere" with viral replication by protecting cells from virus infections. IFNs also have various other functions: they activate immune cells, such as natural killer cells and macrophages; they increase host defenses by up-regulating antigen presentation by virtue of increasing the expression of major histocompatibility complex (MHC) antigens. Certain symptoms of infections, such as fever, muscle pain and "flu-like symptoms", are also caused by the production of IFNs and other cytokines.

Q.10 Basalt is common example of:
A. Extrusive Rocks
B. Intrusive Rocks
C. Sedimentary Rocks
D. Metamorphic Rocks
Correct Answer) A: Extrusive Rocks
Description:
Basalt is an aphanitic extrusive igneous rock formed from the rapid cooling of low-viscosity lava rich in magnesium and iron (mafic lava) exposed at or very near the surface of a rocky planet or moon. More than 90% of all volcanic rock on Earth is basalt. Rapid-cooling, fine-grained basalt is chemically equivalent to slow-cooling, coarse-grained gabbro. The eruption of basalt lava is observed by geologists at about 20 volcanoes per year. Basalt is also an important rock type on other planetary bodies in the Solar System. For example, the bulk of the plains of Venus, which cover ∼80% of the surface, are basaltic; the lunar maria are plains of flood-basaltic lava flows; and basalt is a common rock on the surface of Mars.

A. D
B. B
C. A
D. E
Correct Answer) A: D
Description:
Vitamin D helps regulate the amount of calcium and phosphate in the body. These nutrients are needed to keep bones, teeth and muscles healthy. A lack of vitamin D can lead to bone deformities such as rickets in children, and bone pain caused by a condition called osteomalacia in adults. The body creates vitamin D from direct sunlight on the skin when outdoors.
Vitamin D is also found in a small number of foods.
Sources include:
1. oily fish – such as salmon, sardines, herring and mackerel
2. red meat
3. liver
4. egg yolks
5. fortified foods – such as some fat spreads and breakfast cereals
Another source of vitamin D is dietary supplements.

Q.13 A sexual reproduction in plants is also known as_______.
A. vegetative reproduction
B. sexual reproduction
C. bisexual reproduction
D. rapid reproduction
Correct Answer) A: vegetative reproduction
Description:
Vegetative reproduction (also known as vegetative propagation, vegetative multiplication or cloning) is any form of asexual reproduction occurring in plants in which a new plant grows from a fragment or cutting of the parent plant or a specialized reproductive structure. Many plants naturally reproduce this way, but it can also be induced artificially. Horticulturalists have developed asexual propagation techniques that use vegetative plant parts to replicate plants. Success rates and difficulty of propagation vary greatly. Monocotyledons typically lack a vascular cambium, making it more challenging to propagate.

Q.14 Vertebrates are the animals that have _______ in their bodies.
A. backbones
B. structure
C. skull
D. skins
Correct Answer) A: backbones
Description:
Vertebrate is derived from the word vertebra, which refers to any of the bones or segments of the spinal column. All vertebrates are built along the basic chordate body plan: a stiff rod running through the length of the animal (vertebral column and/or notochord), with a hollow tube of nervous tissue (the spinal cord) above it and the gastrointestinal tract below. In all vertebrates, the mouth is found at, or right below, the anterior end of the animal, while the anus opens to the exterior before the end of the body. The remaining part of the body continuing after the anus forms a tail with vertebrae and spinal cord, but no gut.

Q.15 The adult human brain weighs on average about ________.
A. 0.5 kg
B. 0.8 kg
C. 1.3 kg
D. 1.5 kg
Correct Answer) D: 1.5 kg
Description:
In humans, the right cerebral hemisphere is typically larger than the left, whereas the cerebellar hemispheres are typically closer in size. The adult human brain weighs on average about 1.5 kg (3.3 lb). In men the average weight is about 1370 g and in women about 1200 g. The volume is around 1260 cm3 in men and 1130 cm3 in women, although there is substantial individual variation. Yet another study argued that adult human brain weight is 1,300-1,400g for adult humans and 350-400g for newborn humans. There is a range of volume and weights, and not just one number that one can definitively rely on, as with body mass. It is also important to note that variation between individuals is not as important as variation within species, as overall the differences are much smaller. The mechanisms of interspecific and intraspecific variation also differ.

Q.16 The amount of actual water vapour of air is known as:
A. Dew point
B. Relative humidity
C. Condensation point
D. Absolute humidity
Correct Answer) D: Absolute humidity
Description:
ABSOLUTE HUMIDITY:
Absolute humidity (expressed as grams of water vapor per cubic meter volume of air) is a measure of the actual amount of water vapor (moisture) in the air, regardless of the air's temperature. The higher the amount of water vapor, the higher the absolute humidity. For example, a maximum of about 30 grams of water vapor can exist in a cubic meter volume of air with a temperature in the middle 80s. SPECIFIC HUMIDITY refers to the weight (amount) of water vapor contained in a unit weight (amount) of air (expressed as grams of water vapor per kilogram of air). Absolute and specific humidity are quite similar in concept.

Q.25 Water absorbed by the roots, rises up in the stem through:
A. axillary bud
B. tubules
C. xylem vessel
D. phloem vessels
Correct Answer) C: xylem vessel
Description:
Xylem is the tissue in vascular plants which conducts water (and substances dissolved in it) upwards in a plant. There are two kinds of cell which are involved in the actual transport: tracheids and vessel elements. Vessel elements are the building blocks of vessels, which constitute the major part of the water transporting system in those plants in which they occur. Vessels form an efficient system for transporting water (including necessary minerals) from the root to the leaves and other parts of the plant.
