The journey of the food through the digestive system will actually digest the food. The rest will be given out as feces.
<h3><u>Explanation:</u></h3>
The digestive system actually consists of digestive tract and Digestive glands. The processes that are associated with digestive system is - ingestion, digestion, absorption, assimilation and egestion.
The food that is taken is first smashed and chewed into a rough bolus by mixing with saliva. The salivary amylase slightly digests the starch into dextrin.
Then the food is engulfed through the oesophagus into stomach. Inside stomach, the food is mixed with an enzyme pepsin and HCl. Pepsin digests the proteins into peptones and peptides. The food is converted into a bolus and transported into duodenum.
In duodenum, there are several enzymes from small intestine and pancreas breaks the fats into fatty acids, proteins into peptides and starch into carbohydrates like glucose. They are absorbed and the undigested substances are left over ad feces.
Answer:
They used artificial selection
Explanation:
Breeding animals who had desirable or good traits. For example, they bred cows who produced the most milk and plants that produced the most vegetables. :))
One possible strategy would be to find the cane toads natural predators. if the cane toad does have natural predators, then it can control the population by hunting it and etc. one limitation to this however would be that there has to be an balance between the toad and that natural predator. for example, they need to survive off of each other so there can’t be too many of the toads not so many natural predators and vise verse. (i hope this makes sense i took bio last year)
If about 30% is A then 30% is T. That leaves 40% to be G + C...so each must be around 20%.
Respiration using oxygen to break down food molecules is called aerobic respiration. 'Aero' means air, which contains oxygen, leading to the name aerobic respiration. Glucose is the molecule normally used for respiration - it is the main respiratory substrate. Glucose is oxidised to release its energy, which is then stored in ATP molecules.
The word equation for aerobic respiration is:
glucose + oxygen → carbon dioxide + water (+ ATP made)
You need to be able to recognise the chemical formulas:
C6H12O6 + 6O2 → 6CO2 + 6H2O
