I believe the correct answer from the choices listed above is the last option. Lactase and carbonic anhydrase are examples of enzymes. Lactase is an enzyme produced by a lot of organisms. Carbonic anhydrases, on the other hand, is a family of enzymes that catalyze the rapid interconversion of CO2 and H2O to bicarbonate.
That would be the NOBLE GASES (Helium, Neon, Argon, Krypton, Xenon, Radon). Because these elements have a filled outer shell (thus giving them the full octet that other elements crave), they are stable elements under normal circumstances and as such resist chemical combination.
Plz note that under special conditions, noble gases such as Xenon and Radon can form compounds (Xenon Fluoride and Oxide; Radon Fluoride)
Answer Electromagnetic waves are used to transmit long/short/FM wavelength radio waves, and TV/telephone/wireless signals or energies. They are also responsible for transmitting energy in the form of microwaves, infrared radiation (IR), visible light (VIS), ultraviolet light (UV), X-rays, and gamma rays.
Explanation:
Answer: In theory, the scientific method can be used to answer virtually any question imaginable. The scientific method is a consistent approach to acquiring knowledge that begins with a question and then uses a combination of research, testing and analysis to arrive at the answer to the question.
Answer: The answer is blue, white, yellow-white, orange.
Explanation: These are the two basic reasons for different star colors:
Temperature – cooler stars are red, warmer ones are orange through yellow and white. The hottest stars shine with blue light
Age – As a star ages it produces different chemicals which burn at different temperatures. We can use a star’s color to show its relative age
