Tetrodotoxin is a potent toxin found in a variety of organisms including the pufferfish. The toxin binds to the extracellular side of the Na+ channel and prevents channel opening. This leads to paralysis of muscles, including the diaphragm. Death from respiratory failure can occur after ingestion of as little as 1 mg of the toxin. Why does this toxin cause paralysis? Question 7 options: The axon membranes become over-depolarized. The Na+ channels remain in the inactive, refractory state. The Na+ channel does not open wide enough to allow enough Na+ through the channel. The membrane depolarization is not amplified along the axon.

Answers

Answer:

The correct answer is - The membrane depolarization is not amplified along the axon.

Explanation:

Tetrodotoxin, a neurotoxin present in the liver and gonads of Marine organisms. it can inhibit the soidum channels which means it blocks the entering of the sodium in the cells or neurons if consumed it and it can lead to neurological and gastrointestinal disorders.

These toxins block the signals to move along the nerves to muscles In absence of sodium action potential cannot be sent along the axon by blocking the sodium channels. This results in weakening and paralysis.

A 3-column table has 1 rows. The first column is labeled Gelatin (+ control) with entry pink/purple. The second column is labeled
Water (negative control) with entry pink/purple. The third column is labeled Mystery food sample with entry blue.

The data above indicate an error. How do you know? What might have caused the error?

Answers

Answer:

When tested for proteins neither gelatin or water was not pink/purple

Explanation:

credit to person who commented on question above

Answer:

The water should not be pink/purple because water should test negative for protein. The water should actually have turned blue, because Biuret solution is blue. Someone may have mislabeled the test tube with water. The water may have been contaminated with a protein.

The diagram below represents the time a cell spends in the two main phases
of the cell cycle. In which phase does a cell spend less time?
A. Interphase
B. R phase
C. M phase
O
D. Prophase

Answers

The cell spends less time in the M phase, also known as the mitotic phase, where the actual division of the cell takes place.

What does happen during M phase?

During this phase, the cell undergoes mitosis or meiosis, depending on the type of cell, resulting in the formation of two daughter cells. In contrast, the interphase is the longest phase of the cell cycle, where the cell grows and carries out its normal metabolic activities.

The R phase, also known as the S phase, is a sub-phase of interphase where DNA replication occurs. Prophase is the first phase of mitosis and is relatively short compared to the M phase as a whole.

During prophase, the chromosomes condense, the nuclear envelope breaks down, and the spindle fibers form. In metaphase, the chromosomes align at the metaphase plate.

During anaphase, the sister chromatids separate and move towards the opposite poles. Finally, during telophase, the spindle fibers disassemble, the nuclear envelope reforms, and cytokinesis occurs, resulting in the division of the cytoplasm and formation of two identical daughter cells.

In terms of the amount of time spent in each phase, interphase is the longest, accounting for about 90% of the cell cycle. M phase, on the other hand, is relatively short, accounting for only about 10% of the cell cycle. Therefore, a cell spends less time in M phase than in interphase.

Anthropologist: In an experiment, two groups of undergraduates were taught how to create one of the types of stone tools that the Neanderthals made in prehistoric times. One group was taught using both demonstrations and elaborate verbal explanations, whereas the other group learned by silent example alone. The two groups showed a significant difference neither in the speed with which they acquired the toolmaking skills nor in the level of proficiency they reached. This shows that Neanderthals could just as well have created their sophisticated tools even if they had no language
Which one of the following, if true, most weakens the anthropologist's argument?
(A) Apart from the sophistication of their stone tools, there is a great deal of evidence suggesting that Neanderthals possessed some form of language.
(B) The students who were taught with verbal explanations were allowed to discuss the toolmaking techniques among themselves, whereas the students who learned by silent example were not.
(C) The tools that the undergraduates were taught to make were much simpler and easier to make than most types of tools created by Neanderthals.
(D) The instructor who taught the group of students who learned by silent example alone was much less proficient at making the stone tools than was the instructor who taught the other group of students.
(E) The tools created by Neanderthals were much less sophisticated than the tools created by anatomically modem humans who almost certainly possessed language and lived at the same time as the Neanderthals.

Answers

Answer:

A

Explanation:

The point of this arguement is that with or without speaking they were able to make the same sophisticated and complex tools, if it is true that both had a language that would mean the silent people would have no point and that both types of humans had the same initial factors.
