The correct answer is d. 8p+; 9n; 10e−
Oxygen exists in three isotopes ¹⁶O, ¹⁷O and ¹⁸O. The atomic number of oxygen is 8. It means its nuclei has 8 protons. The given is oxide⁻² anion. This means it has gained 2 electrons. Thus, oxide anion have 8 protons and 10 (8+2) electrons. The number of neutrons depends on the isotope, in this question mass number is given¹⁷O. The mass number is the sum of the protons and neutrons in the nucleus. Hence, number of neutrons oxide anion will be 17-8 = 9 neutrons.
Tornadoes are common in areas of flat plains because its in a region when cold air clashes with warm air. Also, tornadoes requires parent thunderstorm, which flat plain areas such as Oklahoma and Kansas have higher chances of having tornadoes.
C. Food Processor
Explanation - Food processor is an appliance used in the kitchen that performs multiple purposes like blending, chopping, slicing etc. It makes the preparation of food very easy. Depending on the blades attached to the processor, the working of it varies.
It is also very convenient to use and does not require liquid for doing its purpose like electric blender. It is an electricity based device. It works only when the lid is properly closed to ensure there is no spillage of food and the device is safe to use.
Answer: Catalyst. Any molecule that will increase the rate of a chemical reaction, does not participate directly in the reaction and therefore is reusable, and does not supply the energy for the reaction (heat or ATP does). Enzymes work on one reactant, called a. Substrate.

Answer:
Energy flow in ecosystem occurs by food chain from producer to consumers. ... Then energy is transfered from producers to consumers, called as heterotrophs. Primary consumers are called as herbivores. Herbivores are eaten up by secondary consumers, called as carnivores.
