Identify the limitations of the carbon model(s) in accounting for all of<br> Earth's carbon.
Mariana [72]

The carbon model is the flow and the movement of the carbon and its compound in the atmosphere. Climate change is the limitation of the carbon model.

<h3>What is climate change?</h3>

A climate change is a variation in the weather and the climate pattern due to a change in temperature and other atmospheric factors. It will lead to a transformation in the flow of carbon in the environment.

Increased carbon in surroundings increases temperature and results in a change in seasons and humidity levels, leading to changes in the rainfall.

Therefore, climate change is the limitation of the carbon model.

andreyandreev [35.5K]

Answer: The question is incomplete because the options are not given, here are the options from another websites.

A.The enzyme, amylase. which is present in saliva breaks potysaccharide chains into disaccharides.

B. Other enzymes in the small intestine further break the potysaccharide into monosaccharides.

C. You take a bite and to chew the complex carbohydrate into smaller pieces.

D.Amylase is deactivated by the low pH in the stomach.

E.. Monosaccharides are absorbed through the intestinal wad.

The correct order are,

C. You take a bite and to chew the complex carbohydrate into smaller pieces.

A.The enzyme, amylase. which is present in saliva breaks potysaccharide chains into disaccharides.

D.Amylase is deactivated by the low pH in the stomach.

B. Other enzymes in the small intestine further break the potysaccharide into monosaccharides

.E. Monosaccharides are absorbed through the intestinal wad

Explanation:

Carbohydrates are complex or large molecules are they are found in rice, bread e.t.c

Digestion of carbohydrates start from the mouth through a process called mastication i.e chewing of the carbohydrates. The salivary gland then secrete the salivary amylase which act on the chewed carbohydrates. The salivary amylase breaks down amylose and amylopectin present in starches into smaller chains of glucose which is called dextrins and maltose. When it get to the stomach, the amylase cannot further break it because it does not work in acidic conditions. The substance form chyme in the upper stomach and pancreatic enzymes act on it to break it down into simple sugar glucose. The pancreatic enzymes include sucrase, maltase and lactase.

Sucrase breakdown sucrose into glucose and fructose, maltase breakdown maltose in two molecules of glucose and lactase breakdown lactose into galactose and glucose. The simple sugar are then absorbed into the blood through the intestinal wall.
