Answer:
CCK
Explanation:
Cholecystokinin (CCK) acts by generating gallbladder contractions and relaxing the Oddi sphincter together with the action of secretin (another hormone secreted by the gut) that stimulates bile production and decreases acid secretion in the stomach.
When stomach acid is high, it stimulates the secretion of another hormone, secretin, which causes decreased gastrointestinal motility. This has the effect of stopping the transfer of stomach contents to the duodenum, preventing the stomach from emptying too quickly. Secretin in conjunction with CCK will also act on the stomach glands, inhibiting acid secretion.
Hypertonic- plasmolyized
isotonic- flaccid
hypotonic-turgid
it means there is more sugar/ salt concentration in ratio to water
In a microbiology laboratory, a culturing involves growing microbes in the lab. It is the method of multiplication microbes where they are allowed to reproduce under controlled laboratory conditions. Microbial cultures are very important for diagnostic tests in medicine and research in microbiology.
Answer:
There are four things that are required: variation, inheritance, selection, and time. Variations are differences that exist among individuals.
Answer:
B. The two species share many proteins in common, and the nucleotide sequences that code for these proteins are almost identical
Explanation:
When two different species have the similar structure, (trait, behavior) these traits can arise through either of two processes:
- The structure is from the common ancestor that gave rise to the two species and that structures are then known as homologous structures. The species with homologous structures are more closely related to each other.
- The structures could have developed independently as a result of convergent evolution (trait was not present in the ancestor), and those structures are then called analogous structures.
