The answer is C
Explanation: The random change in the gene pool is due to genetic drift. Remember, genetic drift occurs at a more rapid rate when the population size is reduced. The flood is a random occurrence. It could have as easily been a drought.
Answer:
the seeds of plants contain angiosperm (flowering plants) seeds consist of three genetically distinct constituents: (1) the embryo formed from the zygote, (2) the endosperm, which is normally triploid, (3) the seed coat tissue derived from the maternal tissue of the ovule.
A hormone released in the small intestine that stimulates the pancreas to release digestive enzymes and the gallbladder to release bile is known as Cholecystokinin.
Hormones play a huge position for your normal functioning. They manage heart rate, sleep cycles, sexual feature, and replica. Your metabolism, urge for food, growth and development, temper, strain, and body temperatures are all suffering from hormones.
Cholecystokinin is secreted by using cells of the upper small gut. Its secretion is stimulated by using the advent of hydrochloric acid, amino acids, or fatty acids into the belly or duodenum. Cholecystokinin stimulates the gallbladder to settlement and launch stored bile into the gut. Cholecystokinin (CCK) is produced more often than not inside the duodenum and the jejunum. The physiological roles of CCK are the stimulation of pancreatic secretion and the contraction of the gall-bladder. Secretin and CCK are peptide hormones secreted via the endocrine cells inside the gastrointestinal tract. Secretin stimulates the secretion of water and bicarbonate ions from the pancreas, while CCK stimulates the synthesis and secretion of bile juice and pancreatic enzymes.
