Answer c is correct great job
Question: Is the pre-synaptic or the post-synaptic neuron damaged? Explain your rationale in detail (in other words, detail how you came to your conclusion). You're going to have to really think on this one. It's not something you can look up in the text. You will need to use what you have learned about the autonomic nervous system and some critical thinking to arrive at the answer.
Horner's Syndrome riddle: Ach is the neurotransmitter at all ANS preganglionic fibers, including SNS. The pt has decreased sweating and pupil constriction, indicating blockage of SNS transmission. When the MD gave ACh it induced sweating, but not pupil dilation. This is because the sweat glands are an exception in normal SNS transmission, as the postganglionic fibers utilize ACh as their neurotransmitters. Other SNS pathways utilize NE as their neurotransmitter. So ACh acted directly on the sweat gland to produce sweating, but could not stimulate the typical postsynaptic neurons to release NE. When the MD gave NE he saw pupil dilation, but not sweating, indicating the NE worked directly at the iris to produce pupil dilation. This indicaates the problem was with the postsganglionic neuron. If the preganglionic neuron were the problem injecting ACh would have solved both problems.
Answer:
Six examples of density-dependent limiting factors are:
1. Competition within the population.
2. Predation.
3. Disease and parasites.
4. Waste accumulation.
5. Energy supply.
6. Migration.
Cell wall and chloroplasts are found in the plant cell, but they are not found in animal cells.
Answer:
The answer to your question is This molecule has 10 carbons and 20 hydrogens.
Explanation:
- Number of carbons
You can see the picture below, all the edges are carbons and they are numbered, there are 10 carbons.
- Number of hydrogens
Carbon 1 has 3 hydrogens
Carbon 2 has 2 hydrogens
Carbon 3 has 1 hydrogen
Carbon 4 has 2 hydrogens
Carbon 5 has 3 hydrogens
Carbon 6 has 2 hydrogens
Carbon 7 has 1 hydrogen
Carbon 8 has 1 hydrogen
Carbon 9 has 2 hydrogens
Carbon 10 has 3 hydrogens
Total number of hydrogens = 20
