Answer:
The cells differentiate.
Explanation:
Organism can be simply classified on the basis of the cellularity of the organism. Two main types of organism are unicellular organisms and the multi cellular organisms.
Multicellular organism contain different types of cells. The different cells differentiate to perform a particular function. The division of labor property is well shown by the multi cellular organism. The cells of the multi cellular organism must show differentiation process.
Thus, the correct answer is option (d).
Average kinetic energy of the particles in the object
Answer:
b. ion-ion
Explanation:
When NaCl dissolves in water , it dissociates completely into the corresponding ions , i.e. , Na⁺ and Cl⁻ ,
Since , the charges have complete positive and negative charges , hence , they interact with each other via ion - ion interaction , i.e. the interaction between the positive and negative charges , is referred to as ion - ion interaction .
Hence , the correct option is b. ion-ion interaction .
Answer:
A. Motors and generators are opposite processes
Explanation:
B, C, and D are wrong because, the term electrical generator is used to describe a range of devices that convert mechanical energy into electricity. A motor converts electrical energy into mechanical, which is the opposite process to the electrical generator.
