What kind of molecule is formed when many disaccharide molecules are combined

salantis [7]

in what ways is the ocean at 1,000 meters deep different from the ocean at the surface in the same location

photoshop1234 [79]

It is much darker 1000 meters deep and photosynthesis most likely can't occur, the fishes there also have different abilities than the ones higher up in order to survive, also it is probably a harder to swim because of the increased pressure

Arte-miy333 [17]

The heart is a cone-shaped muscular organ located within the mediastinum of the thorax.

The mediastinum is the space lined with membranous tissue between the lungs. The mediastinum contains not only the heart but also the great vessels (pulmonary artery, aorta, pulmonary veins, and the superior and inferior vena cava), as well as parts of the esophagus and the trachea.

Its apex rests on the diaphragm and its superior margin lies at the level of the 2nd rib.

The apex of the heart is the conical area created by the confluence of the ventricles, but mainly by the left ventricle. It rests on the diaphragm. The superior margin of the heart, also known as the base, lies at the level of the second rib.

Approximately two-thirds of the heart mass is seen to the left of the midsternal border.

This is because to the left of the midsternal border lies the left ventricle which comprises most of the heart mass as the left ventricle is the one responsible for pumping blood throughout the systemic circulation and significant pressure should be overcame; resulting to the physiologic hypertrophy of the left ventricle.

The heart is enclosed in a serosal sac called the pericardium. The loosely fitting double outer layer consists of the outermost fibrous pericardium, lined by the parietal layer of the serous pericardium.

The pericardium is one of three layers of the heart (other ones being the myocardium and the endocardium); and is the outer layer of the heart. The pericardium is composed of two tissues, the fibrous pericardium and the serous pericardium. The pericardium functions to lubricate the movement of the heart by the action of the pericardial fluid.

The heart has four chambers. Relative to the roles of these chambers, the atria are the receiving chambers, whereas the ventricles are the discharging chambers.

The four chambers of the heart are namely the right atrium, right ventricle, left atrium, and the left ventricle. Venous blood goes to the right atrium via the vena cavas then to the right ventricle via the tricuspid valve; then to the pulmonary circulation via the pulmonary artery where it will be oxygenated. From the pulmonary circulation, the left atrium will receive the oxygenated blood via the pulmonary veins then to the left ventricle via the mitral valve where it will be pumped to the systemic circulation via the aorta.

Proteins are broken down into ___________ by the enzyme ____________

sergij07 [2.7K]

Answer: Proteins are broken down into amino acids by protease enzymes.

Explanation:

Protein is an essential nutrients which is needed for growth and development. Protein is the major constituent of hormones, enzymes, eyes, muscles e.t.c.

The protein sources are eggs,beans,meats, milk e.t.c.

Protein digestion start in the stomach. Once protein consume get to the intestine, hydrochloric acid and protease enzymes breakdown protein into amino acids.The Amino acids are linked together by peptides bond. The perform this by cleaving to the peptides bond within the protein by a process called hydrolysis.
