Answer:
Option B, Fimbriae are usually shorter than flagella whereas pili are involved in genetic exchange.
Explanation:
Fimbriae are a structure that allows a cell to stick to any surface while flagella are locomotors that allow an organism to move. Due to functional difference, fimbriae are short in length and are more numerous. A pili is a structure that comes out of the cell and hence attaches the cell to the specific surfaces. It also assists in transferring DNAs in cell. Hami are external structures found in archae only.
Hence, option B is correct

Answer:
Ecological and ethological approaches to the study of behaviour. The natural history approach of Darwin and his predecessors gradually evolved into the twin sciences of animal ecology, the study of the interactions between an animal and its environment, and ethology, the biological study of animal behaviour.

Answer;
-Kinetic energy
Explanation;
The energy associated with motion or movement is called kinetic energy.
-Kinetic and potential energies are found in all objects. If an object is moving, it is said to have kinetic energy (KE). Potential energy is stored energy and the energy of position; gravitational energy.
-An object that has motion - whether it is vertical or horizontal motion - has kinetic energy. Kinetic energy is calculated by the formula 1/2mv², where m is the mass of the object and v is the velocity of the object.
-Therefore, kinetic energy depends upon two variables: the mass (m) of the object and the speed (v) of the object.
