Answer: Mouth (amylase digest carbohydrates), esophagus, stomach (digestion of proteins by pepsine), small intestine (digestion of fats, proteins and carbohydrate by pancreatic enzymes and bile), large intestine (it receives the indigestible substances, absorbs the water and leaves the waste products called feces, peristalsis helps move stool into the rectum and feces are expelled from the body through the rectum and anus). Insulin facilitates glucose uptake by the cells and glucagon turns glycogen into glucose.
Explanation:
The gastrointestinal tract is a series of hollow organs joined together in a tube from the mouth to the anus. The organs found there are the mouth, esophagus, stomach, small intestine, large intestine and anus. The liver, pancreas and gallbladder are the solid organs of the digestive tract that also have important functions during digestion.
Digestion is important because the organism needs nutrients to function properly. (carbohydrates, proteins, fats, vitamins). So, the digestive system breaks down nutrients into small parts so that the body can transport and absorb them. During digestion, carbohydrates are broken down into simple sugars, proteins into amino acids and fats into fatty acids and glycerol.
The digestion of food begins in the mouth, where the food is chewed. The saliva possesses enzymes that already begin with the degradation of starches and sugars. The two most important proteins in saliva are amylase (produced by parotid glands) and mucin (produced by sublingual and submandibular glands). When the person swallows, the tongue pushes the food down the throat and the epiglottis folds over the windpipe to prevent choking and so the food passes into the esophagus. The food bolus then passes through the esophagus, where a process called peristalsis takes place to transport the food.
Then the food reaches the stomach, where the upper muscle in the stomach relaxes (esophageal sphincter) to allow the food to enter and the lower muscle of the stomach mixes the food with the digestive juice. This sphincter remains closed to prevent the content in the stomach from flowing back into the esophagus. Protein digestion begins in the stomach with the action of pepsin and continues in the small intestine with pancreatic enzymes such as trypsin (produced in the pancreas), chemotrypsin, aminopeptidases and carboxypeptidases. So, the stomach acid and enzymes act there, which are molecules created by our body that are responsible for breaking down the polymers present in food into smaller molecules so that they can be easily absorbed.
The food then passes into the small intestine and is transported along the small intestine by peristaltic movements. There, fats, proteins and carbohydrates are digested. The small intestine has three parts: duodenum, jejunum and ileum. The pancreas produces pancreatic juice and the liver produces bile, and these two juices are discharged into the small intestine. Bile helps to dissolve fats, which facilitates their assimilation. Meanwhile, the pancreatic juice completes the digestion of proteins and sugars, a process that began in the stomach, together with the intestinal juice produced by the walls of the small intestine. Once the food has been digested, its components must pass into the blood to be distributed to all the organs of the body. The inner walls of the small intestine has intestinal villi which are irrigated internally by blood vessels and they are responsible for the absorption of water and nutrients into the bloodstream. So, when the digestive enzymes have dissociated the large molecules into small components, the products are absorbed by the wall of the intestine. The mucosa of the small intestine also secretes the hormone secretin, which stimulates the pancreas to produce digestive enzymes.
Finally, the large intestine is involved, where bacteria (microbiota) in the large intestine can also chemically break down food. The large intestine includes the appendix, cecum, colon and rectum and it receives the indigestible substances from the small intestine, absorbs the water and leaves the waste products called feces. The colon, is the last structure to process food. Peristalsis helps move stool into the rectum and feces are expelled from the body through the rectum and anus.
After digestion, glucose will be available as a source of energy. Once it begins to circulate in the bloodstream, it will need the help of a hormone called insulin to enter the cells and provide them with the energy they need. Insulin is a peptide hormone secreted by the β cells of the pancreatic islets of Langerhans and it helps cellular glucose uptake by signaling cells to take in glucose from the blood. If the body has enough energy. On the other hand, glucagon turns a type of stored sugar called glycogen into glucose, which goes from the liver into your blood to provide energy.
Why do tree's cells need to make more DNA?
It’s one of the big mysteries of cell biology. Why do mitochondria—the oval-shaped structures that power our cells—have their own DNA, and why have they kept it when the cell itself has plenty of its own genetic material? A new study may have found an answer.

how does fertilizer affect the quality of crops?
Answer:
Fertilizers replace the nutrients that crops remove from the soil. Without the addition of fertilizers, crop yields and agricultural productivity would be significantly reduced. That's why mineral fertilizers are used to supplement the soil's nutrient stocks with minerals that can be quickly absorbed and used by crops

how does fertilizer affect the quality of crops?
[tex] \huge \mathsf \pink{Answer}[/tex]
The role of fertilizers in food production is usually underestimated. Fertilizers are food for plants.
Fertilizers replace the nutrients that crops remove from the soil. Without the addition of fertilizers, crop yields and agricultural productivity would be significantly reduced. That’s why mineral fertilizers are used to supplement the soil’s nutrient stocks with minerals that can be quickly absorbed and used by crops.
Put simply – we use fertilizer to: Provide nutrients not available in the soil.Replace nutrients removed at harvest.Balance nutrients for better. producequality and higher yield.What is the name of the bond that is created when two amino acids

If the sugar has a carbonyl group within the carbon skeleton, we call it?
Glucose, Ketose ,Aldose,Galactose?
Answer:
Ketose
Explanation:
Monosaccharides also known as simple sugars are usually represented in a linear chain with a carbon skeleton. All the carbons present with the exception of one have a hydroxyl group that can be attached on either side of the skeleton.
Aldehyde sugars or aldoses such as glucose and galactose have a carbonyl group that is present at the end of the carbon skeleton. Monosaccharides also known as "ketone sugars", example fructose have their carbonyl group located at other parts of the carbon skeleton.
In animals, glucose is absorbed from the gut into intestinal cells against its concentration of gradient. This one-way process requires energy to work. Which of the following best describes how glucose is absorbed into intestinal cells?
A. By osmosis
B. By diffusion
C. By a buffer
D. By active transport
Answer: Glucose is absorbed through the intestine by a transepithelial transport system initiated at the apical membrane by the cotransporter
Explanation:
if im wrong ill give you your points
Osmosis best describes how glucose is absorbed into intestinal cells.
What do you mean by osmosis?
Osmosis is the movement of water molecules from a solution with a high concentration of water molecules to a solution with a lower concentration of water molecules, through a cell's partially permeable membrane.
Osmosis is when water moves from an area of LOW solute concentration (low osmolarity) to an area of HIGH solute concentration (high osmolarity) through a semipermeable membrane. Osmosis is one of the most important ways that plants and animals achieve homeostasis.
The absorption of water from the soil is due to osmosis. The plant roots have a higher concentration than the soil. Therefore, the water flows into the roots. The guard cells of the plants are also affected by osmosis.

In general, do organisms that have more traits in common also share more genes?
Answer:
In general, organisms that share similar physical features and genomes tend to be more closely related than those that do not. Such features that overlap both morphologically (in form) and genetically are referred to as homologous structures; they stem from developmental similarities that are based on evolution.
