3. A periscope consists of two plane mirrors placed at an angle of 45°.

4. When light falls on one of the mirrors then after reflection from the first mirror it falls on the second mirror which further reflects it and falls on the eye of the observer.

 1. Among these, olive cultivation is studied in olivoculture.

2. Olives originated in the region of Southern Europe near the Mediterranean Sea. Currently, the largest producing countries are in the same region, with Spain, Italy, Morocco, Turkey and Greece being the largest producers.

1. Excretion is the process in which all metabolic wastes are passed out of the body. Excretion in humans occurs in several processes through various organs and internal organs of the body.

2. Diffusion is the most common process of excretion in lower organisms. The human body is an extraordinary machine, where various life-processes (respiration, circulation, digestion, etc.) occur simultaneously. As a result, many of the waste products produced in our bodies are in various forms including carbon dioxide, water, and nitrogenous products such as urea, ammonia, and uric acid.

1. Neurons are the building blocks of the nervous system. They receive and transmit signals to different parts of the body. This is done in both physical and electrical forms. Many different types of neurons facilitate the transmission of information.

2. Neurons are the structural and functional unit of the nervous system. All neurons have three distinct parts – dendrites, the cell body, and the axon. Neuron structure is specially adapted to quickly carry messages in the form of electrical signals over large distances in the body.

1. Temporal lobe – integrates memories with the senses of taste, sound, sight, and touch.

2. Parshivika Pali – Holds information about temperature, taste, touch and movement.

3. Frontal lobe – responsible for communicative functions and control of voluntary movement or activity.

4. Occipital lobe – responsible for vision

1. The proton was discovered by Rutherford. The name proton is derived from the Greek word protos meaning 'first'. The proton is a positively charged particle located in the nucleus of an atom, which was discovered by Ernest Rutherford in 1920. Rutherford proved in 1917 that the nucleus of the hydrogen atom (ie a proton) is present in the nuclei of all other atoms.

2. The nucleus of the atom was discovered by Ernest Rutherford in his famous gold foil experiment in the year 1911. The value of the particle is 1.6*10-19 C. To make an atom neutral, it has the same number of protons and electrons. He used the same concept to discover the proton.
