Cell wall, cell membrane, nuclear membrane.
The correct answer is that the axon would not be able to produce action potentials.
Majorly all the pufferfish comprises of tetrodotoxin, an element that produces foul tasting and is generally lethal to fish. In the case of humans, tetrodotoxin is hazardous, that is, up to 1200 times more poisonous in comparison to cyanide. There is an adequate toxin in one pufferfish to kill 30 adult humans and there is no antidote.
Dissimilar than scientists thought
Answer: This is the long-term carbon cycle. So, carbon takes up various forms: glucose in plants, carbon dioxide in the air and hydrocarbons like coal.
Answer:
Biogeography, the study of the geographical distribution of organisms, provides information about how and when species may have evolved. Fossils provide evidence of long-term evolutionary changes, documenting the past existence of species that are now extinct.
To give one classic example, the forelimbs of whales, humans, and birds look quite different on the outside. That's because they're adapted to function in different environments. However, if you look at the bone structure of the forelimbs, you'll find that the organization of the bones is remarkably similar across species. It's unlikely that such similar structures would have evolved independently in each species, and more likely that the basic layout of bones was already present in a common ancestor of whales, humans, and birds.
