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
Answer:
C. a string of nucleotides that can be used as a template to produce a RNA that codes for a protein.
Explanation:
A gene is a specific sequence of DNA containing genetic information required to make a specific protien and is a string of nucleotides (DNA in cells) that can be used as a template to produce a RNA (by transcription) that codes for a protein. The produced RNA might be the end product (for example some transfer RNA's) or might be further translated into a protein. An organism's entire complement of DNA is its genome.
Microtubules originate on the centre of the cell taking the positive end to the periphery of the cell, while the negative end remains turned to the centre of the cell. The melanosomes move along these microtubules using motor proteins desiganted kinesins and dyneins. The kinesins are responsible for moving the melanosomes to the positive end of the microtubule (periphery of the cell) generating dark-colored cells, whereas dyneins move the melanosomes to the negative end of the microtubule (centre of the cell) generating light-colored cells.
Antarctic fish. To stop their blood from freezing, some fish that live in the arctic and Antarctic have special Antifreeze proteins. Antifreeze proteins are very clever, as they slow down the formation of bonds between water molecules, which prevents the formation of ice crystals in the fish's blood.
