The answer is e. Calcitonin, Aldosterone and Atrial natriuretic peptide.
The calcitonin is a hormone secreted by the thyroid gland. Calcitonin is involved in the regulation of the levels of calcium and phosphate in the blood. Aldosterone is a hormone secreted by the adrenal gland. It is essential for maintaining the store of sodium in the kidney, salivary glands, sweat glands and colon. Atrial natriuretic peptide (ANP) or Atrial natriuretic factor (ANF) is a peptide hormone synthesized, and secreted by cardiac muscle cells in the heart. ANP is involved in the regulation of sodium levels in the cells of the heart.
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:
Many farmers use chemical herbicides to kill weeds and
insecticides to kill insects. Using genetic engineering, scientists
have developed ways to resist harmful crop pests. In this Gizmo,
you will use genetic engineering techniques to create genetically
modified corn.
