Tetrodotoxin blocks voltage-gated sodium channels, and ouabain blocks sodium-potassium pumps. If you added both tetrodotoxin and ouabain to a solution containing neural tissue it will result in immediate loss of action potential with gradual shift in resting potential.
When the voltage gated sodium channels are blocked then any threshold would not be able to cause an action potential thus, there will be an immediate loss of action potential and any depolarization step.
Moreover, when sodium potential pumps are blocked there is no influx or out flux of sodium or potassium ions thus the concentration of ions inside increases resulting in the gradual shift in resting potential.

Answer:
an organisms haploid number of chromosomes is 40 what would be this organisms diploid number?
Diploid number of an organism with haploid number of 40 is 80 chromosomes
Explanation:
Aaah I’m sorry if I’m wrong idk how to do this stuff, but I searched everything up and this is what I got
1. “B”- Codon
2. “A”- Anticodon
3. “C”- TRNA
4. “B”- Bond to the DNA strand to carry the code for protein synthesis out of the nucleus.
Answer: Savanna
Explanation:
The Savanna is a biome located in Africa and characterized by a lot of grass and dispersed trees. The climatic conditions are warm all year round and the summers are wet.
The presence of so much vegetation makes it an ideal biome for large herbivores like elephants, giraffes and wildebeests. As a result of so many herbivores being there, there are lots of carnivores as well such as lions and cheetahs.
the answer is external auditory meatus
