Explanation; -A water molecule can act as an acid or a base even in a sample of pure water. It acts as an acid (donates H+) when it reacts with a stronger base, say sodium hydroxide.
Answer: hybridisation between related species is unlikely to contribute to adaptive speciation.
Explanation: any population has natural genetic variation. The available resources are insufficient for all plants (and conversely, not all offspring survive). Natural selection favours variations better suited to the conditions.
Although hybridisation is more common in plants than animals, and can lead to speciation, adaptive radiation from an ancestral species is the general response to environmental change, such as from rainforest to savanna. There is low probability of selective advantage from hybridisation of two ancestral species adapted to niches within the original habitat when the conditions in those niches changes significantly.
Answer:
<em>Vacuole</em>
Explanation:
Vacules are the storage bubbles within the cell. They store food, nutrients and/or other organic compound which might cell require during starving conditions. They are more than one in animla cells but relatively smaller. The diagram shown is the schematic representation of the animal cell.
No it could not. It would benefit society by knowing when that volcano will erupt so we could evacuate and save lives.
Answer:
The shapes of continents fit together like a puzzle. The matching coastlines show where the continents broke apart. Identical rocks that formed over 200 million years ago have been found on different continents.
