Assuming that you mean not (p or q) if and only if P ~(PVQ)--> P so now construct a truth table, (just place it vertical since i cannot place it vertical through here.) P True True False False Q True False True False (PVQ) True True True False ~(PVQ) False False False True ~(PVQ)-->P True True True False if it's ~(P^Q) -->P then it's, P True True False False Q True False True False (P^Q) True False False False ~(P^Q) False True True True ~(P^Q)-->P True True False False
No. Nitrogen makes up 78% of the air we breathe. Oxygen makes up 21%.
For Apex the answer is “True“.
false
This describes one kind of statement that can appear in a logical syllogism or argument. If a given argument A is true, then it follows that argument B must be true. It does not automatically follow that if B is true, then A must be true.'All living humans are breathing animals' is true. [If you are a living human (A) you breathe (B).'All breathing animals are therefore human' is not true. [If you breathe (B) you are a living human (A).
True. Nitrogen makes up about 78% of Earth's atmosphere, which is the air we breathe.
false
false
True. Nitrogen fixation is the process by which certain bacteria convert atmospheric nitrogen gas into a form that plants can use, such as ammonia or nitrates. This process is essential for providing crops with the nitrogen they need to grow and thrive.
true
True
False, the more oxygen you need the faster you will breathe.
No, this is false.
true!
false, when the plant dies in this case, nitrogen is returned to the soil
it is false
False. Animals do not get nitrogen directly by eating decomposers. Rather, animals obtain nitrogen by consuming plants or other animals that have already processed and absorbed nitrogen from the environment. Decomposers break down organic matter and release nitrogen back into the soil, where plants can then absorb it.
