How do you construct a truth table for parenthesis not p q parenthesis if and only if p?
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
True or false A corollary is a statement that can be easily proved using a theorem?
For Apex the answer is “True“.
True or false The independent variable is the variable that is changed in an experiment?
false
What describes the meaning of the statement If A then B?
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.

[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 or false Is nitrogen the main element found in the air you breathe?
True. Nitrogen makes up about 78% of Earth's atmosphere, which is the air we breathe.
Is it true or false that Nitrogen fixation makes nitrogen gas useful to crops?
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.
Frogs can breathe air through their skins true or false?
false
Protista are ecologically important because they process nitrogen through nitrogen fixation is that true or false?
False. While some Protista may play a role in nitrogen fixation, their ecological importance is primarily related to their role as primary producers in aquatic ecosystems, providing food for higher trophic levels and contributing to the overall ecosystem functioning.
TRUE or FALSE are humans multicellular organisms?
false
Apes and humans are classifed as hominids true or false?
true
True or false Most mollusks breathe with ciliated gills located in their mantle cavity?
True
Is it true that the more oxygen you need the more slowly you breathe?
False, the more oxygen you need the faster you will breathe.
Is it true that nitrogen is not used to make ammonia and nitric acids?
No, this is false.
Is it true or false The amount of nitrogen oxygen and water vapor in the atmosphere varies from place to place?
True. The amount of nitrogen, oxygen, and water vapor in the atmosphere can vary depending on location, altitude, weather conditions, and human activities. These variations can impact local air quality and climate.
The nitrogen cycle may be described as nitrogen moving from the air to the soil where plant roots use it as food. when plants die nitrogen is returned to the air true or false?
false, when the plant dies in this case, nitrogen is returned to the soil
True or false bacteria are used in food production to benefit humans?
