Answer:

Liquid is the correct answer.

Explanation:

The hydrosphere contains the total amount of water on a planet. The water is on the surface, ground and in the atmosphere. Hydrosphere can be in liquid, gas and solid forms. On earth, the water exists in liquid form in lakes, oceans, and rivers. The frozen part of the water is in the form of an ice cap and icebergs. In hydrosphere, the water moves in a cycle. which leads to the transformation of water from one form to another, it is called the water cycle. The waterfalls in the form of rain and snow and are collected by lakes and ocean. It again evaporates into the atmosphere and the cycle starts again.

Answer:

a= In scientific notation

6.96000×10⁵ Km

b =In expanded notation

0.00019 mm

Explanation:

Given data:

Radius of sun = 696000 Km

size of bacterial cell = 1.9 ×10⁻⁴ mm

Radius of sun in scientific notation = ?

Size of bacterial cell in expanded notation = ?

Solution:

Scientific notation is the way to express the large value in short form.

The number in scientific notation have two parts.

. The digits (decimal point will place after first digit)

× 10 ( the power which put the decimal point where it should be)

for example the number 6324.4 in scientific notation will be written as = 6.3244 × 10³

Radius of sun:

696000 Km

In scientific notation

6.96000 × 10⁵ Km

The expanded notation is standard notation of writing the numerical values which is normal way. The numbers are written as they are, without the power of 10.

Size of bacterial cell:

1.9 ×10⁻⁴ mm

In expanded notation

1.9/ 10000 = 0.00019 mm

√is related to membrane permeability to solutes.

Explanation:

Tonicity of a solution can be explained as how an extracellular solution can give room for the liquid to move in and out of the cell through osmosis.

It should be noted that Tonicity of a solution is
