<span>A change in a organism's surroundings that causes the organism to react is called a stimulus</span>
<span>When frog matures from tadpole to adult, its gills are lost and develops functioning lungs. After maturity, frogs are still able to breathe through their skin---- known as “bimodal breathing,” wherein an animal uses two different systems for bringing in oxygen. These two different breathing systems allow adult frogs to shift between aquatic habitats (which require skin respiration) and land habitats (which are more suited to lung respiration).</span>
Fungus uses its hyphae to obtain nutrients.
The answer is Because the resting plasma membrane is more permeable to potassium
Plasma membrane is more permeable to potassium(kalium) than sodium(natrium) which makes it easier to move between intracellular fluid and extracellular fluid. But the concentration of the ion still regulated strictly by the cell using pump and transporter in their membrane. The pump is doing active movement(against gradient of concentration) and need ATP to do so.
Answer: convergent evolution
Explanation:
The similar shapes of fast swimming marine predators are an example of convergent evolution.
Convergent evolution shows how different species possess identical structures even though they evolve separately. Convergent evolution typically takes place with the organisms that are not really related.
An example of convergent evolution is the similarity that can be noticed in the wings or the flights of bats, birds, insects, etc
