Answer
1.1 organisational levels of organism are
-cellular level: organism is composed of one cell or multiple cell with distinct functions.
-Tissue level: organism is composed of tissue having different types of cell but performing a specific function by each tissue
- Organ level: here organism is composed of various organs formed by different types of tissye and each organ perform a specific function or sets if function
1.3 structure is the study of features of the organism and function are study of mechanism of process
1.4 Diversity of life
It is defined as variations present among the organisms in different parts of the world.
1.5 Natural selction:
Organism who are fit will survive and who are unfit will not survive. Natural selection are due to come favourable change in the organism that helps them to survive. These changes bring evolution in the organism
2.1
Atoms- smallest paticle and unit of elements
Molecules : smallest unit of Compound. They aee made up of more than two types of atoms. E.g H2O is a molecule for water compound which is made up of 2H and 1 O atoms
Elements: these are the subtance made up of large number of one type of atoms. E.g Gold, Silver etc
Compound: these are the subtance made up of large number of molecules
E.g Water (H2O) Carbon dioxide (CO2)
2.2 subatomic particles are
Electrons: negative charge - 1.6 x10-19 C
Present in the orbit around the nucleus wit mass 9.1 x 10-31 kg
Protons: positive charge +1.6 x10-19 C
Present inside the nucleus with mas 1.672 x10-27 kg
Neutrons: No charge present in the nucleus with mass 1.674 x 10-27 kg
2.3 atomic number : it is eqaul to number of proton in the nucleus of atom of an element
Atomic mass number: Number of protons and neutrons in the nucleus of an atom.
