The source is the allele for beak size being different, or more specifically the DNA sequences being different.
Answer:
Explanation:
The wastewater system relies on the force of gravity to move sewage from your home to the treatment plant. So wastewater-treatment plants are located on low ground, often near a river into which treated water can be released. ... From here on, gravity takes over to move the wastewater through the treatment process
Answer:
All the choices are correct
Explanation:
- Listeriosis is caused by a microorganism called Liateria that can grow refrigerator temperatures.
- It is a foodborne disease and can be found in deli meats and dairy products.
- Some people do not present with symptoms and a blood test will confirm the diagnosis.
- In some severe cases it can lead to complications which include meningitis and sepsis
Am certain that the aquifex bacteria might be classified as extremophiles.
Exremophiles are organisms that have been discovered on earth that survive in environments that were once thought not to be able to sustain life. The extreme environments include intense heat, highly acidic environments, extreme pressure and extreme cold. <span />
It is pertinent to understand what hypertonic, hypotonic, and isotonic solution means before setting out to explain how a cell reaches equilibrium in each type of solution.
- A hypertonic solution is one whose solute concentration is higher than that of the sap of a cell that is immersed in it.
- A hypotonic solution is one with the same solute concentration as that of the sap of the cell immersed in it.
- An isotonic solution has a lower solute concentration than that of the sap of the cell immersed in it.
In biological systems, water molecules move by osmosis from the region of higher water potential or lower concentration of solutes to the region of lower water potential or higher concentration of solute. An equilibrium is reached when there is no net movement of water between two sides. Hence;
- A cell placed in a hypertonic solution will lose water to the surrounding solution until an equilibrium is reached. This means that such a cell will end up shrinking (wilting) or even dying due to loss of water from the cell sap.
- A cell placed in a hypotonic solution will gain water from the surrounding solution until there is no net movement of water anymore. Such a cell might become turgid or even burst out its cell content.
- A cell placed in an isotonic solution will neither gain nor lose water because the cell sap and the surrounding solution have equal solute concentrations.
