1 Respiration in Plants
The number of ATP molecules used during glycolysis is 1) 8 2) 6 3) 2 4) 10
During glycolysis, one glucose molecule is split into two pyruvate molecules, using 2 ATP while producing 4 ATP and 2 NADH molecules
2 Structural Organisation in Animals
Ground substance of cartilage consist of proteoglycans, some lipid, collagen. The carbohydrates are glycosaminoglycans and include 1) Chondroitin sulphate 2) Hyaluronic acid 3) Keratan sullphate 4) All of the above
SOLUTION
The ground substance of cartilage shows a special carbohydrate association called chondroitin sulphate that is responsible for building the new cartilage,
3
The final electron acceptor during oxidative phosphorylation is: 1) oxygen 2) water 3) carbon dioxide 4) ATP
4
Athlete's foot is caused by-
(1) Aspergillus fumigatus
(2) Trichophyton
(3) Histoplasma
(4) Candida
5 Animal Kingdom
Which one of the following is not an Annelid ?
1) Nereis 2) Pheretima 3) Hirudinaria 4) Urchin
Solution
Sea urchins are spiny sea creatures that are round and prickly like hedgehogs. They belong to Echinoderm phylum.
Other options are examples of phylum Annelida - Nereis, Pheretima (Earthworm) , Hirudinaria, etc.
6 Evolution
The scores of dog breeds that are exhibited in dog shows are the outcome of 1) Natural selection 2) Artificial selection 3) Sexual selection 4) Special creation
7
The experimental system used in studies of the discovery of replication DNA has been1. Drosophila melanogaster2. Pneumococcus3. Escherichia coli4. Neurospora crassa
8 Morphology of Flowering Plants
A plant in which secondary rachii are modified into phyllodes is 1) Acacia melanoxylon 2) Opuntia dillenii 3) Parkinsonia aculeata 4) Asparagus racemosus
Rachis is modified into a leafy structure called Phyllode. Phyllode is a modified rachis or petiole of leaf. It is green in colour and can perform photosynthesis.
9
Study of nuclear cytology is1. Neurology2. Rhinology3. Mycology4. Karyology
10 Animal Kingdom
Chloragogen cells of earthworm are analogous to 1) liver of invertebrates 2) kidney of vertebrates 3) liver of vertebrates 4) uriniferous tubules
Chloragogen cells in annelids function similarly to the liver in vertebrates. The cells store glycogen and neutralize toxins, are yellowish in colour due to the presence of yellow granules, called as chloragosomes and are present in coelomic fluid of some annelids.
