Answer: Van der Waals forces
Explanation:
Van der Waals forces are weak intermolecular forces that depend on the distance between two particles. They are caused by correlations in the change in polarization between two nearby particles. To put it in other words, when a particle changes its polarization (becomes more positive on one end and more negative on the other), so does the adjacent particle, and the next one, and so on. This causes these particles to stick together weakly.
The tiny "hairs" increase the surface area of the gecko's feet in contact with the wall, which makes the bond stronger and allows it to support all of its weight.
Because experiments have shown that geckos stick well to both hydrophobic and hydrophilic surfaces, we can assume there aren't any hydrogen bonds present.
Ionic bonds can't be present either because geckos wouldn't stick to electrically neutral surfaces, as these bonds require charged molecules.
small chicken farms turned into factories because it was cheaper to
maintain and it also made it cheaper for people to buy eggs. However
this produced a huge problem of what to do with the chicken manure
and this is also a problem amongst other types of livestock as well as well as factories having big oil spills hope this helps sorry didnt know what you wanted for a answer
Endocrine system is involved in this
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.
