<h3>
Answer:</h3>
Biotic
<h3>
Explanation:</h3>
We are being tested on whether we can differentiate between abiotic and biotic factors in an ecosystem.
- We need to know that factors that affect living organisms in an ecosystem are classified into abiotic factors and biotic factors.
Then, what is the difference between abiotic and bioitic factors?
- Abiotic factors are non-living factors that affect living organisms in an ecosystem while biotic factors are living factors that affect organisms in an ecosystem.
What are examples of Biotic and abiotic factors.
- Examples of abiotic factors include wind, temperature, humidity, climate,. etc.
- Examples of abiotic factors include parasitism, mutualism, commensalism, etc.
How do we arrive at the answer to our question?
- A Paramecium swimming in a lake; this is a biotic factor.
- Because paramecium is a living organism which relates with other organisms in the lake ecosystem in various way.
Answer:
For question 1 the answer is D, Because the higher you are the more PE you have.
Answer:
The mean value theorem tells us the average velocity must be between the minimum velocity and the maximum velocity. The only way it can be either the minimum or the maximum is if velocity is constant. So of course instantaneous velocity can be greater and can be less.
Explanation:
Answer: 6.38 moles of 
are needed to react with 2.55 mol of 
Explanation:
The balanced chemical reaction for the combustion of ethyne is:
According to stoichiometry:
2 moles of require = 5 moles of
Thus 2.55 mol of require = 
moles of
Thus 6.38 moles of are needed to react with 2.55 mol of
