Observe the cells from buccal epithelium stained with Giemsa under microscope.

Correct Answer - D Since due to wrong connection of each cell the total emf reduced to `2epsilon` then for wrong connected of three cells the total emf will reduced to...

Robert Hooke observed cells under the microscope for the first time. [Note. Cell walls were first observed by Robert Hooke (1665) as he looked through a microscope at dead cells from...

Correct Answer - B (b) Resolving power of microscope=`(2musintheta)/lamda` Since, `lamda_(R)gtlamda_(B)` hence, resolving power increases.

Correct Answer - C (c ) Given, n=1.5, and `h_(o)=3cm` Refractive index, `n=h_(o)/h_(i) rArr 1.5=3/h_(i)` Apparent depth , `h_(i)=3/1.5=2 cm` Hence, 3-2=1 cm upwards.

It is Anaphase.

1. In fern rachis, the number of vascular bundles is less as compared to number of vascular bundles in monocot stem. In monocot stem, vascular bundles are numerous.  2. In fern...

Molars is maximum in number in the human buccal cavity.

Correct Answer - c Simple epithelium is a tissue in which the cells are cemented directly to one another to form a single layer . An epithelium is a sheet or...

Correct Answer - B The wall of alveoli is highly vasularised.It is surrounded by flattened non cillitated squalmous cells to increase the surface area. Simple columnar ciliated cells line the few...
