The answer is B. The higher the concentration of substrate, the FASTER a reaction happens (since there are more opportunities for molecules to collide in a way that favours the reaction), so B is an incorrect statement.
The other three options describe correct features of catalysts and/or enzymes (which are considered “biological catalysts”).
Answer:
The lowest level, which is usually the producers.
Explanation:
This is because on every level of the trophic system, some energy is lost before the next level. So the level with the least lost energy is the lowest
If your body has developed a tolerance to a medication you're taking, it means the medication at your current dose has stopped working as effectively as it once did. It might mean your body becomes used to the medication, and you don't get the same benefits or effects as before. Drug tolerance is indicative of drug use but is not necessarily associated with drug dependence or addiction. The process of tolerance development is reversible and can involve both physiological factors and psychological factors.
The answer is All of above
There is no context so I will just explain what a constant is:
In an experiment following the scientific method, a constant is a variable that cannot be changed or is purposely not changed during the experiment.
An example would be:
If a researcher wanted to study the effects of temperature on the growth and development of garden snakes, the experimental variable for the experiment would be temperature. All other variables would need to remain consistent to avoid invalid data. The size of the cage, amount of light, food and many other variables would need to remain constant to ensure accurate results and a valid study. Those variables are constants. Some variables are not under a scientist's control, but are still considered to be constants. These constants are called universal constants and include gravity, the speed of light and electronic charge. Universal constants do affect experiments but will be constant through an experiment without being controlled by the scientist.
