What is ohm\' s law |
|
Answer» At a constant temperature the current flowing through conductor is directly proportional to the potential difference across the current i.e V=RI Where R = resistance In short when I is directly proportional to R where R is resistance andI is current. According to ohms law , at constant temperature, the current flowing through a conductor is directly proportional to the potential difference across its ends. It states that electric current is proportional to voltage and inversely proportional to resistance. |

What happened when we mix milk with curd |
| Answer» Due to its fat and protein contents, on reaching the stomach, milk coagulates to form curd.

How do amoeba respiration |
| Answer» Amoeba is a unicellular organism which lives in fresh water. This organism does not have a specialized organ to do the process of respiration. So in amoeba respiration takes place through its cell membrane also called plasma membrane. Amoeba gets oxygen gas dissolved in surrounding water through its plasma membrane by the process of diffusion. The oxygen gas diffused inside the body is used up by amoeba. In the body the oxygen gas absorbed is used to break down the complex food material into simple molecules. During these metabolic reactions in the body of amoeba the oxygen gas is converted into carbon dioxide gas. The carbon dioxide gas is also liberated in the surrounding water through the same process of diffusion. | |

what is efflorescence ? give an example. |
| Answer» Efflorescence is the loss of water (or a solvent) of crystallization from a hydrated or solvated salt to the atmosphere on exposure to air.Efflorescence means "to flower out" in French is the migration of a salt to the surface of a porous material, where it forms a coating. The essential process comprises the dissolving of an internally held salt in water, or occasionally in another solvent. The water, with the salt now held in solution, migrates to the surface, then evaporates, leaving a coating of the salt.Example is Gypsum (CaSO4.2H2O) is a hydrate solid that, in a sufficiently dry environment, will give up its water to the gas phase and forms anhydrite (CaSO4). | |

What is function of brain |
| Answer» Tasks of brain involves receiving information from the rest of the body, interpreting that information, and then guiding the body\'s response to it. Types of input the brain interprets include odors, light, sounds, and pain. The brain also helps perform vital operations such as breathing, maintaining blood pressure, and releasing hormones (chemical signals that control certain cells and organs).The brain is divided into sections. These sections include the cerebrum, the cerebellum, the diencephalon, and the brainstem.The cerebrum is the largest part of the brain. It is responsible for memory, speech, the senses, emotional response, and more.The cerebellum is below and behind the cerebrum and is attached to the brain stem. It controls motor function, the body\'s ability to balance, and its ability to interpret information sent to the brain by the eyes, ears, and other sensory organs.The functions the brain stem governs include respiration, blood pressure, some reflexes, and the changes that happen in the body during what is called the “fight or flight” response.\xa0The diencephalon is inside the cerebrum above the brain stem. Its tasks include sensory function, food intake control, and the body\'s sleep cycle. | |
