Explanation:
<em>
Homo sapiens</em> has dominated the world because of the features they evolved to adapt in the living conditions.
The physical characteristics that are developed by the<em> Homo sapiens</em> are:
1. Bipedalism- enabled the species to survive in grasslands and forests, to run after the prey to eat them.
2. Brain size- the increased size of the brain allowed the species to understand and analyse the world from a new perspective.
3. The use of hands as a tool to use the natural resources.
4. Sexual dimorphism- allowed the species to raise babies with more care.
Answer:
Charles Darwin had concluded that these birds had somehow evolved to adapt based on the island they were on. Each island had different food sources so if these finches wanted to survive they had to change. Each finch adapted to their environment due to forcefully evolving to survive.
Explanation:
Vacuole can occupy up to 90% of the cell volume and can exert turgor pressure against the cell membrane when it acquires water.
In biology, a vacuole is a membrane-bound space found in the cytoplasm of a plant cell.
These are large size compartments that can occupy up to 90% volume of water.
In fully grown plants, vacuoles play a very significant role as they help out in plant growth, storing water, disposing of waste materials, and protecting cells against external barriers.
In sum, vacuoles are generally small in size but important cell organelles that are present in bacteria, fungi, and protozoa.
