Answer:
- Unconditioned stimuli, US: getting hurt by hot water.
- Conditioned stimulus, CS: hearing a toilet flush.
- Unconditioned response, UR: feeling pain after hurting.
- Conditioned response, CR: being afraid when hearing a toilet flush.
Explanation:
- Unconditioned stimuli: Biologically significant stimuli that provoke an unlearned or reflex reaction. For example, getting hurt by hot water.
- Conditioned stimuli: neutral, innocuous or biologically not significant stimuli. For example, hearing a toilet flush.
- Unconditioned Responses: Unlearned response that is triggered by reflex because of an unconditioned stimulus. For example, feeling a lot of pain after hurting by hot water.
- Conditioned Responses: These are provoked by conditioned stimuli. This refers to a learned response that reflects the association between conditioned and unconditioned stimuli. For example, being afraid when hearing a toilet flush.
Initially, an unconditioned stimulus does not provoke any response, but after enough exposition to conditioned and unconditioned stimuli together, the simple presence of unconditioned stimuli induces conditioned responses. In this aspect, the subject has learned to predict or to anticipate the unconditioned stimulus.
When an ecosystem has a scarce nutrient, that is when there is a nutrient limitation.
So the answer is C. <span>Nitrogen is typically the limiting nutrient in freshwater environments.
This is because Nitrogen is the "scarce" nutrient </span>
Answer:
D
Explanation:
D. The second cell would not be able to produce as much food because it could not capture sunlight.
Based on these facts, we can state that the genes of the two organisms had a eukaryotic origin.
We can arrive at this answer because:
- Despite having exons, prokaryotes do not have introns in their genomes.
- This means that if two organisms have the same sequence of introns and exons, they have a common ancestor, in addition to having their genes originated in a eukaryotic organism, which explains the sequence of introns.
This means that the genetic expression of these two organisms has similarities, even if they are organisms with different biological processes.

The process is called denaturation.
I hope this helped :)
