,Q. An atom is defined as a smallest particle of ____
i) A compound that can take part in chemical reaction
ii) An element that can take part in chemical reaction
iii) A molecule that with other molecules
iv) An isotope that can take part in chemical reaction
v) A compound that reacts with other compounds
Q. The three domains of life are____
A. Eukarya, fungi and bacteria
B. Eukarya, fungi and animalia
C. Eukarya, archaea and fungi
D. Eukarya, archaea and bacteria
E. Eukarya, bacteria and animalia
Q. Organisms are currently divided into three domains, named
A) Bacteria, Archaea, and Eukarya
B) Bacteria, Viruses, and Eukarya
C) Bacteria, Archaea, and Prokarya
D) Viruses, Archaea, and Eukarya
Q. Van der Waals interaction is a bond formed by ____
i. Polar positively charged and polar negatively charged atoms
ii. Polar positively charged and non-polar negatively charge atoms
iii. Non-polar positively charged and non-polar negatively charge atoms
iv. Positively charged and negatively charge atoms
v. Non-polar positively charge and negatively charged atoms
(Van der Waals interactions: Non-polar covalent bonds may have positively and negatively charged
regions where very weak bonds can be formed when the atoms and molecules are very close together.)
Q. Cellulose and chitin are examples of
a. Monosaccharides
, b. Disaccharides
c. Polypeptides
d. Polysaccharides
e. Proteins
Q. Cellulose and starch are examples of ____.
a. Disaccharides
b. Lipids
c. Monosaccharides
d. Polysaccharides
e. Proteins
Q. The form of carbohydrates that forms part of the exoskeleton in insects is
1. starch
2. cellulose
3. glycogen
4. chitin
Q. Chitin is an example of a _____
A. Polypeptide
B. Polysaccharide
C. Fat
D. Nucleic acid
(Chitin Structure: The structure is similar to cellulose except that chitin has a nitrogen – containing
appendages in its glucose monomer. Functions: The exoskeleton of arthropods, (insects, spiders,
crustaceans and related animals is composed of chitin. In fungi, it is used as the building material for
their cell walls.)
Q. The electron configuration 1s22s22p6 (6) belongs to____
A. Carbon
B. Neon
C. Oxygen
