Answer:
mutations

It was Charles Darwin who called the birds seen on the Galapagos islands as the finches. These birds show a remarkable diversification in their beak based on their chief food.
What are Darwin's Finches?Charles Darwin observed a group of small sparrow like black birds with strong, short beaks which are known today as Darwin's finches. These finches varied on different islands, but they were closely related to one another.
These finches evolved from a common ancestors to have different beaks well suited for different types of food they feed on. Generally long and pointed beaks are suitable for seed and cactus feeders. Even some short beaked finches tear up the base of the cactus and feed on its pulp.
The slender and sharp beaks are common in insect eating finches. The process by which they successfully evolved and radiated to different habitats is called the adaptive radiation.

The picture shows a contractile vacuole of a unicellular freshwater organism. The contractile vacuole regulates the flow of water into and out of the cell in an aquatic environement. What condtions cause the contracile vacuole to fill with water? Your answer: The concentration of water is greater outside the cell than inside the cell. The concentration of water inside the cell is the same as the concentration outside the cell. The temperature of water in the vacuole is higher than the temperature of its environment.
Answer:
The concentration of water is greater outside the cell than inside the cell.
Explanation:
In living cells, water moves by Osmosis across the cell membrane, which acts as the semi-permeable membrane. Osmosis is the movement of water molecules from a region of high water concentration (low solute concentration) to a region of low water concentration (high solute concentration).
The contractile vacuole of this freshwater organism helps regulate water intake and exit by storing excess water. According to osmotic flow, water will flow into the organism via its cell membrane (semi-permeable membrane) because the concentration of water outside the cell is high than inside the cell, hence, this causes an osmotic gradient causing water to flow into the cell. The water that flows into the cell is stored in the Contractile vacuole.
