Answer:
Red allele frequency will be highest in population II
Population III can undergo bottleneck effect
The frequency of the brown allele will least likely be altered in the population I
Explanation:
Population I -
Total population - 
Brown birds - 
Red birds - 
Population II
Total population - 
Brown birds - 
Red birds - 
Population III
Total population - 
Brown birds - 
Red birds - 
Frequency of red birds in population I
Frequency of red birds in population II
Frequency of red birds in population III
Red allele frequency will be highest in population II and it will be equal to 
as compared to 
in case of population I and III
Population III can undergo bottleneck effect because of smaller population size
The frequency of the brown allele will least likely be altered in the population that has highest brown individual , i.e population I
A hypertonic solution has:
Fewer water molecules outside the cell than are inside the cell. Thus, option "A" is correct.
<h3>What is hypertonic solution?</h3>
- The cell is in a hypertonic solution because it lost water through osmosis and shrunk.
- A hypertonic solution contains more solute molecules compared to solvent molecules while the hypotonic solution has more solvent molecules than solute molecules.
- When a plant cell is placed in a hypertonic solution it loses water through osmosis and shrinks.
- An animal cell placed in a hypotonic solution absorbs water through osmosis, increases in size and then bursts. Plant cell, on the other hand, does not burst when placed in a hypotonic solution as it contains a cellulose cell wall.
Thus, option "A" is correct.

Answer:
primary
Explanation:
Primary succession occurs when new land is formed or bare rock is exposed, providing a habitat that can be colonized for the first time. For example, primary succession may take place following the eruption of volcanoes, such as those on the Big Island of Hawaii. As lava flows into the ocean, new rock is formed.
Invasive firestorm method. All pests are now dead with the added benefit of fewer trees to infest.
Answer:
Immunity to Small Pox
Explanation:
Over the years, Europeans had built up an immunity to smallpox because many had contracted the disease and still survived. As the population grew children were born with some immunity to the disease. When the Europeans arrived in the Americas, and smallpox spread around the native peoples, the Europeans did not contract the disease because they were immune. However, since the natives were not immune, they slowly died of due just to the disease as well as some parts of the war between the europeans.
