Answers:

1.Answer: C

A dynamo is a device that converts mechanical energy into electrical energy

2.Answer: C

The viscosity of a fluid is the measure of its resistance to gradual deformation by shear stress or tensile stress. For liquids, it corresponds to the informal concept of “thickness”: for example, honey has a higher viscosity than water.

3.Answer: A

4.Answer:  D

A wavemeter (or wavelength meter) is a kind of interferometer which is used for precise wavelength measurements on laser beams. There are different variants, including scanning wavemeters and static devices with no moving parts.

5.Answer: A

6.Answer: B

Aqua regia is a mixture of nitric acid and hydrochloric acid, optimally in a molar ratio of 1:3. Aqua regia is a yellow-orange fuming liquid, so named by alchemists because it can dissolve the noble metals gold and platinum, though not all metals.

7.Answer: C

Picric acid is an organic compound with the formula (O₂N)₃C₆H₂OH. Its IUPAC name is 2,4,6-trinitrophenol. The name “picric” comes from the Greek πικρός, meaning “bitter”, reflecting its bitter taste. It is one of the most acidic phenols.

8.Answer: B

Tomato (Solanumlycopersicum L.) is the most intensively investigated Solanaceous species both in genetic and genomics studies. It is a diploid species with a haploid set of 12 chromosomes and a small genome

9.Answer: A

Pluripotent cells can give rise to all of the cell types that make up the body; embryonic stem cells are considered pluripotent. Multipotent cells can develop into more than one cell type, but are more limited than pluripotent cells; adult stem cells and cord blood stem cells are considered multipotent.

10.Answer: C

Bryophytes are an informal group consisting of three divisions of non-vascular land plants: the liverworts, hornworts and mosses. They are characteristically limited in size and prefer moist habitats although they can survive in drier environments

11.Answer: B
