Describe what would happen to the abiotic factors within the ecosystem if the bacteria were eradicated from the ecosystem.
Answer: If a abiotic factor was to be removed from the ecosystem it can affect the entire ecosystem and all of the organisms that live there
Explanation:
Abiotic means which does not have life for example air, water, soil. Absence of bacteria can influence the abiotic factors in adverse ways.
What are abiotic factors?Abiotic components plays a major role in ecosystem, while biotic components are dependent on abiotic factors for their survival.
Both abiotic and biotic factors are related to each other, if any of these factors changes, it will adversely affect the ecosystem.
For instance, if bacteria were eradicated from ecosystem, it will affect the functioning of abiotic components which can result in increased pH, decreased decomposition etc.
Thus, the abiotic factors will get affected adversely if bacteria were eradicated from the ecosystem.

Answer:

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.

Why do elderly persons often develop bowed back and appear to lose height?
Answer:
When we get older, we experience a loss of bone density and our bones begin to thin and become weaker, which results in osteoporosis, causing us to develop bowed backs and appear to lose height.
We lose bone density as we age, and our bones start to thin and weaken. This leads to osteoporosis, which makes us appear smaller and causes us to acquire bowed backs.
What is osteoporosis ?Osteoarthritis is an osseous disease that arises when the body makes either too little bone or loses too much bone. Like a result, bones deteriorate and are more prone to breaking from a trip or, in extreme circumstances, from tiny bumps or sneezes. Under a magnification, healthy bone resembles a honeycomb; the term "osteoporosis" refers to porous bone.
What is treatment of osteoporosis?Typically, bisphosphonates are used initially for treating osteoporosis. Among these is the when first tablet Alendronate (Fosamax). Weekly or monthly pills of was also (Actonel). Ibandronate (Boniva), a tablet taken every month or an IV infusion given every 3 years. The most accurate test for identifying osteoporosis and determining the risk of fracture is commonly believed to be bone density testing by DXA now at hip and spine. Some persons get peripheral DXAs, which assess the thumb and heel bone densities.

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.
