solid and liquid
solid
Answer:
gas
Explanation:
In gas there are weak attraction forces present between the particles.
Properties of gases:
Molecule of gases randomly move everywhere and occupy all available space.
Gases don't have definite volume and shape and take the shape and volume of container in which it present.
Their densities are very low as compared to the liquid and solids.
Gas molecules are at long distance from each other therefore by applying pressure gases can be compressed.
The very weak inter molecular forces are present between gas molecules.
Properties of Liquid:
Liquid have definite volume but don,t have definite shape.
Their densities are high as compared to the gases but low as compared to the solids.
In liquid, molecules are close to each other and have greater inter molecular forces as compared to the gas molecules.
Properties of solids:
Solids have definite volume and shape.
In solids molecules are tightly pack and very close to each other.
Their melting and boiling point are every high.
The densities of solids are also very high as compared to the liquid and gas.
There are very strong inter molecular forces are present between solid molecules.
b. It was successful.
c. It explained his theory of evolution.
d. It was based on his findings in South Africa.
It was based on his findings in South Africa; is not true Darwin’s book On the Origin of Species
The theory on " Charles Darwin's book "On the Origin of Species" stated that:
" individuals with traits that enable them to adapt to their environments will help them survive and have more offspring, which will inherit those traits"
Evolution simply means the way or process by which different kinds of living things were believed to have originated or developed from earlier forms

Answer:
The correct answer is option D.
Explanation:
Darwin's book on the origin of species explains his theory of evolution and he was working on this book's manuscript over three years time period. The origin of species is well known and was very successful. So, all three statement are correct.
The book was based on findings on Galapagos island and South America not in south africa. This book explained natural selection on the survival of the fittest theory.
Thus, the correct answer is option D.
A part of the cell theory is cells come from pre-existing cells. The correct option is A.
The cell theory is the conclusion of many scientists. There are three postulates of the cell theory. They are: all organisms are made up of cells. New cells are made up of old cells, and the cell is the basic structural and functional unit of life.
The cell is the smallest and basic unit of life. All functions of the body are performed by cells. It contains a cell organelle that has different functions and structures.
A nucleus is present in the cell and microscopic organs must have a single cell, they are not a part of cell theory, this is more related to the organism, not cells.
Thus, the correct option is A. cells come from pre-existing cells.

Answer:
Cells come from pre-existing cells
Explanation:
b) become cancerous
c) fail to exchange materials
d) divide
B.Smog
C.Acid rain
D.Carbon dioxide
d. Carbon Dioxide

B. Fog
C. Stratus
D. Cumulonimbus
The correct answer is Cumulus.
These clouds look puffy and is flat in bottom. They look like cauliflower and are white colored too.
These forms of clouds floats in the sky and seems to be like floating cotton. They are located at 3300 feet above the ground.
They always grow in upward direction and can sometimes form giant structures which are known a the giant cumulonimbus which is responsible for thunderstorms.
