The right ventricle transports oxygenated blood to the lungs true or false

adell [148]

I believe the correct answer is FALSE.

<h2>Explanation:</h2>

The heart is an organ located at the center of the chest in the thoracic cavity and functions to supply blood to and from tissues giving the tissues oxygen and nutrients while taking away carbon dioxide and waste products. It is divided into 4 chambers and 2 chambers are separated by a muscular wall that prevents mixing of the blood.

<h2>Further Explanation:</h2>

Blood enters the heart via the vena cava which is divided into the superior vena cava that recieves blood from the upper region of the body that includes the head, neck and chest while the inferior vena cava recieves blood from the lower extremeties that includes the legs, the abdomen, the pelvic region and the thighs. The blood is deposited into the right atrium and is de-oxygenated. When it is deposited into the right atrium, the change in volume of the atrium and the expansion causes the valve to open and allow the de-oxygenated blood to flow into the right ventricle. The right ventricle then pumps the blood that is de-oxygenated to the lungs via the pulmonary artery which is the only artery that pumps de-oxygenated blood. In the lungs, carbon dioxide is removed and oxygen added to the blood and is taken to the left atrium which pumps the oxygenated blood to the left ventricle and then the left ventricle pumps the oxygenated blood to the rest of the body. The blood is then again taken through the body via the capillaries and the veins pick up the blood that has been removed of oxygen and added with carbon dioxide and transport the blood back to the heart via the vena cava. It enters the right atrium via both the inferior and superior vena cava and the de-oxygenated blood is circulated again to the lungs for oxygenation from the left ventricle.

Most proteins destined to enter the endoplasmic reticulum _________. Group of answer choices are transported across the membrane

Svetlanka [38]

Answer:

Begin to cross the membrane while still being synthesized-C

Explanation:

The Endoplasmic Reticulum is a part of the endomembrane system of the cell which is mostly reponsible for the synthesis and modification of proteins, although synthesis of lipids in plant and animal are carried out here

For more synthesis of proteins, it

needs to be further transported into the Rough endoplasmic reticulum- the designated site for secretion after synthesis of proteins.

Also it has been found out that when this proteins enter the Endoplasmic Reticulum, they start to cross the membrane while still being synthesized.

What feature of alcohol fermentation makes it more suitable for the baking process than lactic acid fermentation?

Ludmilka [50]

Answer:

The correct answer is : B. Carbon dioxide gas is produced as a by-product of alcohol fermentation but not lactic acid fermentation.

Explanation:

In t5he lactic fermentation, the end product is lactic acid whereas in Alcohol fermentation produces by-product carbon dioxide gas which makes it more suitable for baking.

Alcohol fermentation takes place the bread is made as gas is what puts tiny air bubbles within the dough of the bread and makes bread lighter consistency we are used to. Yeast helps in producing carbon dioxide by alcohol fermentation.
