Match the gastric phase on the left (1-3) with the correct description on the right (4-6):
dem82 [27]

Answer:

1 and 5,

2 and 6,

3 and 4

Explanation:

Intestinal phase: stomach empties and decreases secretions

The intestinal phase is the phase where stomach empties its contents(chyme) and decreases secretion. In this stage the duodenum responds to arriving chyme and moderates gastric activity through hormones and nervous reflexes.

The Chyme is the semi-fluid mass of partly digested food that is expelled by the stomach, through the pyloric valve, into the duodenum.

Gastric phase: stomach secretes juice and mixes food into chyme

The gastric phase is a period in which swallowed food and semi-digested protein ( peptides and amino acids ) activate gastric activity  which secretes juice and mixes food into chyme. About two-thirds of gastric secretion occurs during this phase.

Cephalic phase: prepares stomach for arrival of food

The cephalic phase of digestion is the gastric secretion that occurs prior to when food enters the oral cavity. Cephalic phase result from the ignition of  visual, olfactory, and auditory inputs to the brain and also induce anticipatory responses i.e  prepare the gastrointestinal tract for the meal.

The length of bamboo grows much faster than that of thickness why?​
iren [92.7K]

Using a slow- and fast-growing variant of bamboo, Wei and colleagues looked at cell division, growth, and gene expression (through transcriptomics, which measures all the genes being expressed by an individual) to discover which genes may be responsible for fast growth in bamboo. They found that the slow-growing variant had reduced expression of genes relating to cell wall construction, the plant hormone auxin (important for cell growth and cell division), and had irregular cell growth and cell walls. Wei and colleagues suggest that a reduced ability to produce and perceive auxin, combined with a weakened cell wall, are responsible for the slow growth seen in the bamboo variant.
