A students holds a mineral up to the light Hardness is the correct answer
Answer:
option D. continuous muscle spasms and convulsions
Explanation:
Sarin is an organophosphorus synthetic compound and is highly toxic. Sarin toxic is colorless and odorless. It act as a potent nerve agent and used as a chemical weapon. This toxic substance binds irreversibly with the enzyme acetylcholinesterase. This enzyme is responsible for degrading acetylcholine. The toxin interferes with the normal functioning mechanism of nervous system.
The organism poisoned by sarin could suffer paralysis, vomiting, continuous muscle spasms and convulsions. Thus, option D is correct.

Question: Which phrase defines a law?
A. a possible explanation or answer to a scientific question that is based on prior knowledge or research and is testable
B. A statement of fact that is generally accepted to be true and universal because it has always been observed to be true.
C. a hypothesis or group of related hypotheses that can be accepted as true based on repeated experimentation with similar results
Answer:
Correct answer: B). A statement of fact that is generally accepted to be true and universal because it has always been observed to be true.
Explanation:
A scientific law may be defined as the something that appears to be true and is universally applicable. Scientific laws do not explain why the observed events happen, but it only states that the event occurs in the same way over and over. Example of scientific law is a law of gravity. Gravity is always there and it always works in the same manner. Other examples include newton's law of motion, which states how the things move.
Answer:
There are two ways plants can achieve this. First, they can minimize the resistance to diffusion of CO2 through the stomata (i.e., have lots of large, open stomata). Second, they can maximize the biochemical rate of fixation (i.e., have high concentrations of photosynthetic enzymes).
