Answer:
It controls the rate at which chyme enters the small intestine
Explanation:
Cephalic phase is one of the phase of gastric secretion (other two are gastric phase and intestinal phase) that begins even before food enters the oral cavity. Thinking of food stimulates the release of gastric juice via parasympathetic nervous system). Food that enters the stomach also stimulates the secretion of gastric juice by parietal cells. Partially digested food directly activates G cells (Enteroendocrine cells) to secrete gastrin which also stimulates the release of gastric juice.

Plasmid is mostly found in bacterial cell, but few can be found in animal cells
In order for a barrier island to form, the coastal sand is organized into barrier islands. There are three conditions for an Island of this type to form.
1. There must be a sufficient supply of sand to form the island.
2. The sea level must be rising.
3. There needs to be winds and waves with sufficient energy to move the sand around

Genetic engineering is the process of manipulating genes for practical purposes. today, scientists have genetically engineered many types of organisms including crop plants. which of the following is a current benefit gained from genetically engineered crops? a. some genes can be transferred to wild plants in the area. b. some animals develop allergies to the genetically engineered crops. c. some food staples, such as rice, contain more nutrients. d. some disease resistant fruits and vegetables are less flavorful.
Answer:
. b. some animals develop allergies to the genetically engineered crops. c. some food staples, such as rice, contain more nutrients
Explanation:
Rice is global staple food. It is mostly affordable by the poor and peasant farmer wordwilde.Vitamin A is an important vitamin for good eye sight and also for boosting the immunity.
This useful vitamin is present in eggs, cheese and liver. Which are expensive for poor families Some small quantity are produced as carotene found in carrot. However, a precursor of Vitamin A called Pro-vitamin A carotenoids is present in the part of rice called the Aleurone layer.
However this part of the rice is not in the endosperm thus the vitamin are washed way during processing of white rice .Although this is present in brown rice. Basically, the energy storage in most crop seeds is stored in the endosperm. Thus the vitamin in the rice are not stored are therefore not imbibe during consumption.
Therefore in order to incorporate carotenoid into the endosperm to avoid been wasted, Daffodil was used. The genes for the transcription of carotene in daffodils and from particular soil bacteria called Pantoea Anantis were extracted, to transfer carotenoid into the rice endosperm. This is called the Golden rice,, because the rice appear golden from the incorporation of the carotenoid into the endosperm though genetic engineering. This appear orange from the carotene pigment present in the endosperm.
Thus from the consumption of the rice ,poor family could imbibe vitamin A into their diet.
Answer:
2
Explanation:
When blood sugar (glucose) rises, the pancreas releases insulin into the bloodstream which helps in lowering the blood sugar level either by storing the excess glucose as fat or as glycogen.
This type of mechanism is regarded as a negative mechanism. It helps to regulate blood sugar level.
Therefore, the increase in insulin level when there's an increase in blood sugar level (glucose) can best be explained by a feedback mechanism that regulates blood glucose level.
