Answer 1

Explanation:

Osmosis the gradual passing of a liquid through a thin layer of material (a membrane).

द्रव्याच्या पातळ थरातून (अंतस्त्वचा) पदार्थ हळूहळू जाणे; तर्षण, परासरण.

Detel information:-

the tendency of a fluid, usually water, to pass through a semipermeable membrane into a solution where the solvent concentration is higher, thus equalizing the concentrations of materials on either side of the membrane. the diffusion of fluids through membranes or porous partitions.

Tissue:-Biology. an aggregate of similar cells and cell products forming a definite kind of structural material with a specific function, in a multicellular organism. tissue paper.

Detel information:- A tissue is an ensemble of similar cells and their extracellular matrix from the same origin that together carry out a specific function. Organs are then formed by the functional grouping together of multiple tissues.

Defined density Density is a measure of mass per volume. The average density of an object equals its total mass divided by its total volume. An object made from a comparatively dense material (such as iron) will have less volume than an object of equal mass made from some less dense substance (such as water).

defined colloid A colloid may be a mixture of one substance that may spread out evenly inside another substance. They may be in two different phases or states of matter. ... Definition: A colloid is a substance microscopically dispersed evenly throughout another substance.

Detel information

a homogeneous non-crystalline substance consisting of large molecules or ultramicroscopic particles of one substance dispersed through a second substance. Colloids include gels, sols, and emulsions; the particles do not settle, and cannot be separated out by ordinary filtering or centrifuging like those in a suspension.

Answer 2

Answer:

A. a......

1.) Osmosis : It may be defined as the process in which water molecules move from high concentration to lower through semi permeable membrane . For example Dates kept in water undergo Osmosis due to which they appear to be fresh, soft and inflated.

2.) Tissue : It may be defined as group of similar or dissimilar cells that perform a specific function.

There are various types of Tissue :

a.) Epithelial Tissue

b.) Skeletal Tissue

c.) Adipose Tissue

d.) Connective Tissue

3.) Density : It may be defined as ratio of mass to the volume. It is represented by ' P'.

Mathematically,

Density = Mass / Volume

Density = m / V

Units of Density :

Density = Kg / metre cube

4.) Colloid : It is a heterogenous solution in which particles are too small but visible the path of light.

For example Ink in water , milk in water.
