The correct answer is option a. true.

The fossil fuels, including coal and oil are present very deep inside the earth. In the carbon cycle, only fixation of atmospheric carbon dioxide in the organic material takes place. This cycle does not involve the recycling of the fossil fuels.

The burning of the fossil fuels directly release carbon dioxide and other carbon compound in the atmosphere, which was not involved in the cycle when it was present deep beneath the earth and ocean. Hence, the burning of fossil fuels increases the amount of carbon in the carbon cycle.

An intestinal hormone that stimulates the release of insulin from the pancreatic islet cells is?
slava [35]

Secretin is a hormone produced in the intestines that promote the release of insulin from pancreatic islet cells.

Discussion about secretin:

  • When fatty acids and acidic chyme are present, secretin is released. It performs a number of functions by attaching to secretin receptors, the majority of which are related to digestion and acid neutralization.
  • In its principal function, secretin tells the pancreas to release bicarbonate ions into the pancreatic juice, raising the pH to between 8 and 8.3 in order to neutralize the acidic chyme. The pancreatic juice's digesting enzymes may function at their best as a result, safeguarding the duodenum's lining.
  • Additionally, secretin controls the pyloric sphincter's tightness, gastrin release, HCl synthesis, and small intestine motility.

As a result, secretin also encourages the pancreas to produce more insulin in response to ingesting glucose.

galina1969 [7]

Answer:

option 4, y=1/4x+16

Explanation:

to solve this you must find the slope and the y intercept.

slope is rise/run, and equal to 2/8 or 1/4

then, the find the y intercept, find where the line crosses the y axis. Here it is 16.

finally you plug these answers into the slope intercept form, y=mx+b. In this form, m= slope, x=days, and b= y intercept.

after you plug in your answers you are left with y=1/4x+16.
