Q1. A coal fired combustion facility reports the following annual emissions for greenhouse gases: Carbon Dioxide - 500 t/y(m)Nitrous Oxide - 500 kg/yNatrual Gas - 5 t/y(m)Sulfur Hexafluoride - 50 g/yGreenhouse Warming Potentials (GWP) are: 21 for CH4, 300 for N2O, and 23,900 for SF6The CO2eq emissions are:
Answer : Option C
Explaination / Solution:
No Explaination.
Q2. Ground tissue consists of
Answer : Option D
Explaination / Solution:
The ground tissue of plants includes all tissues that are neither dermal nor vascular. It can be divided into three classes based on the nature of the cell walls.
Q3. The radius of the innermost electron orbit of a hydrogen atom is 5.3×10–11 m. What are the radii of the n = 2 and n =3 orbits?
Answer : Option B
Explaination / Solution:
No Explaination.
Q4. What is the difference between the taxonomic categories of division and phylum?
Answer : Option A
Explaination / Solution:
In case of plants, classes with a few similar characters are assigned to a higher category called division, whereas phylum was used to refer animals. Hence, the correct option is Division refers to plants whereas phylum refers to animals.
Q5.
What will be the correct order of vapour pressure of water, acetone and ether At . Given that among these compounds, water has maximum boiling point and ether has minimum boiling point?
Answer : Option A
Explaination / Solution:
Water has maximum boiling point due to hydrogen bonding so its vapour pressure will be least because of low boiling point less amount of water will move to vapour phase at a particulat temperature so lesser will be the vapour pressure.
Q6.
Identify the cytokinin given below.
Answer : Option B
Explaination / Solution:
Cytokinin is of different types. The cytokinin shown above is of kinetin which promotes cell division. It was isolated by Miller and Skoog from autoclaved herring sperm DNA.
Q7. The molarity of 900 g of water is
Answer : Option A
Explaination / Solution:
M=900/18 as density of water is 1g/ml.
Q8. HYVP remained confined to which five crops
Answer : Option A
Explaination / Solution:
High Yielding Varieties Programme was introduced in 1964-65 with a new dimension of agricultural production created in the community development project. It includes 5 crops wheat,rice,jowar,bajra and maize. The objective of this programme is to adopt HYV for maximum production.
Q9. Which of the following organism produce gemmules as asexual reproductive structure?
Answer : Option C
Explaination / Solution:
Gemmules are asexual reproductive structure produced by sponges. Chlamydomonas produce zoospores, hydra produce buds and Penicillium produces conidia.
Q10. Phosphorus will not make part of
Answer : Option A
Explaination / Solution:
Phosphorus is not present in amino acids. Nucleic acids, ATP and Teeth contain phosphorus. Amino acids polymerases to form protein.
