1. Normal Human blood pressure is
[A] 110/110
[B] 120/70
[C] 120/80
[D] 140/60
Show Answer
Correct Answer: C [120/80]
Notes:
Blood Pressure is expressed in two numbers. The higher number is known as Systolic Pressure, or the amount of force (as measured in millimetres of mercury) that is exerted against the artery walls during a heartbeat (contraction). The lower number in the Diastolic pressure, which does the force exist while the heart is resting between beats.
2. The Stomata in the aquatic plants is ________?
[A] Not Found
[B] Found & available on both the surfaces
[C] Found & available on upper surface only
[D] Found and available only on lower surface
Show Answer
Correct Answer: C [Found & available on upper surface only]
Notes:
The Stomata in the aquatic plants is found and available on upper surface only. Stomata are crucial for plant functioning as they play fundamental role in the regulation of gas exchange between the plant and its surrounding environment.
3. Sugar , Amino Acids, & Nucleotides are constituents of respectively ___________ ?
[A] Polysaccharides, Proteins. Nucleic Acids,
[B] Proteins, Carbohydrates , Fats
[C] Nucleic Acids. Proteins, Polysaccharides
[D] Polysaccharides, Nucleic Acids. Proteins,
Show Answer
Correct Answer: A [Polysaccharides, Proteins. Nucleic Acids,]
Notes:
Sugar, Amino Acids, & Nucleotides are constituents of respectively Polysaccharides, Proteins and Nucleic Acids. Nucleotides are organic molecules which are the building blocks of nucleic acids.
4. Among Globulin, Albumin, Glutein and collagen which protein is abundant in Eggs?
[A] Globulin
[B] Collagen
[C] Albumin
[D] Thaimine
Show Answer
Correct Answer: C [Albumin]
Notes:
Albumin is most abundant in eggs. Albumin is a family of globular proteins are water-soluble, moderately soluble in concentrated salt solutions, and experience heat denaturation. Substances which contain albumins are called albuminoids.
5. In which of the following Cloaca which is the posterior opening that serves as the only such opening for the intestinal, reproductive and urinary tracts is present?
[A] Aves only
[B] Aves & Amphibians
[C] Aves, Amphibians and Reptiles
[D] Pisces, Aves, Amphibians & Reptiles
Show Answer
Correct Answer: C [Aves, Amphibians and Reptiles]
Notes:
Cloaca which is the posterior opening that serves as the only such opening for the intestinal, reproductive and urinary tracts is present in Aves, Amphibians and Reptiles. A cloaca is not present in placental mammals.
6. Which among the following is found in a Bacteriophage?
[A] only RNA
[B] only DNA
[C] Both RNA & DNA
[D] Either RNA or DNA
Show Answer
Correct Answer: D [Either RNA or DNA]
Notes:
Either RNA or DNA is found in a Bacteriophage. A bacteriophage which is also informally known as a phage, is a virus that infects and replicates within bacteria and archaea.
7. A plant belonging to which of the following groups would show least adaptation to marine water?
[A] Pteridophytes
[B] Gymnosperms
[C] Angiosperms
[D] Bryophytes
Show Answer
Correct Answer: C [Angiosperms]
Notes:
A plant belonging to angiosperms group would show least adaptation to marine water. Angiosperms are vascular plants that have stems, roots, and leaves.
8. Which among the following is the edible part in Rice?
[A] Fruit
[B] Cotyledons
[C] Endosperm
[D] Embryo
Show Answer
Correct Answer: C [Endosperm]
Notes:
Most of the essential micronutrients are almost exclusively stored in the husk, aleurone and embryo of rice, which are removed during the polishing process. Polishing of rice is required as the oil-rich aleurone layer turns the seed rancid upon storage and therefore making rice unsuitable for consumption. Consequently, the rice endosperm that comprises the edible part of rice for humans lacks or contains only small amount of key micronutrients (e.g., iron, zinc, protein, provitamin A, and other vitamins) that are essential for a healthy diet. Considering the facts above and severity of widespread micronutrient malnutrition, iron biofortification in rice endosperm is a promising strategy to overcome iron deficiency effectively.
9. The Trans-fats cause problems in human body because__:
[A] The fat molecules contain high energy that cause oxidation of the tissues
[B] The structure of the fat molecules is such that more molecules can fit in lesser space
[C] The fat molecules contain lesser energy and can not be used so easily
[D] None of the above reasons
Show Answer
Correct Answer: B [ The structure of the fat molecules is such that more molecules can fit in lesser space]
Notes:
Trans unsaturated fats are particularly risky because the double bond stereochemistry allows the fat molecules to assume a linear conformation, which leads to efficient packing (i.e., plaque formation).
10. Opium is a plant product obtained from which part of the plant?
[A] Roots
[B] Stem bark
[C] Dried Latex
[D] Dried leaves
Show Answer
Correct Answer: C [Dried Latex]
Notes:
The opium poppy straw is harvested from cultivation of pharmaceutical entities, the liquid or dried sap (known as opium latex that is obtained by lancing the outer surface of poppy pods) is the starting material for the clandestine production of heroin. Poppy straw is derived when latex are fully mature and dried by mechanical means.
