sp2606 [1]

Answer:

Resting potential

Explanation:

This is because , the resting potential is negative in side of the cell because it has more negative charge inside than outside due to accumulation of alot of sodium and potassium ions. when an axon is at rest in the cell, the anions produce negative charge, the sodium pumps eject sodium out of the cell and potassium is injected in, and the sodium gates and potassium gates are all closed.

Chloroplasts

In plants and algae, which developed much later, photosynthesis occurs in a specialized intracellular organelle—the chloroplast. Chloroplasts perform photosynthesis during the daylight hours. The immediate products of photosynthesis, NADPH and ATP, are used by the photosynthetic cells to produce many organic molecules. I have taken the test before

Owl butterflies feed on mostly fruit, and owls feed on small animals. The images show an owl butterfly and an owl. How does the
Olegator [25]

Answer:

The adaptation in owl butterfly helps it to camouflage and also protects it from predators. Adaptations allow organisms to be better suited to their environment. So the answer is both 'A' and 'B' .

Explanation:

Owl butterfly use the concept of mimicry. It is a form of <em>adaptation</em> in which they fool the predator in thinking that they are owls and not butterflies. These butterflies have eyespots under their wings. By flashing them they look like the <em>eyes </em>of an owl.

Since owls feed on small animals, and small animals feed on butterflies, the owl butterflies protect themselves from predators. The small animals thinking that the butterfly is an owl, run away instead of coming closer. This way these small insects camouflage and protect themselves.

What is speciation?​
lorasvet [3.4K]

Answer:

speciation is when one species splits off into multiple species.

In-depth answer:

Speciation can happen in 4 different ways, the first being Allopatric Speciation, where 2 groups of the same species are physically separated for extended periods of time, and when they're re-introduced, they don't breed.

Sympatric Speciation is when 2 groups of the same species aren't seperated, but form different behaviors that isolate them reproductively (the groups wont inter-breed)

Parapatric Speciation is when 2 groups of the same species are suddenly placed into a new environmental niche, and adapt in different ways to fill that niche.

Quantum Speciation is much less recognized, but it's when a new species rapidly evolves and 'buds off' from the original group
