There is no set lifespan.It can live as long as the environment can support its life. However the average lifespan differs for each particular species, with an average life expectancy from a few days to a year or two.

2. Beginning with the superior vena cava, trace the path followed by a red blood cell as it passes into and through the heart, t

Katen [24]

Answer:

BLOOD PATHWAY:

Body > superior and inferior vena cava > right atrium > tricuspid valve > right ventricle > pulmonary semilunar valve > pulmonary artery > lungs > pulmonary vien > left ventricle > bicuspid/mitral valve> left ventricle > Aortic semilunar valve > Aorta > Body

The pathway goes like this:

From the body (we don't say first because this is a cycle), unoxygenated blood collected goes to the heart via the INFERIOR and SUPERIOR VENA CAVA then it empties into the RIGHT ATRIUM from there it passess through a valve called TRICUSPID valve, which prevents backflow of blood to the right atrium. The blood goes to our first pumping chamber, RIGHT VENTRICLE. The right ventricle pumps the blood through the PULMONARY SEMILUNAR VALVE which leads to the PULMONARY ARTERIES, which happens to be the only arteries that carry unoxygenated blood. From there it goes to the lungs to pick up oxygen and rid itself of carbon dioxide. The blood then goes back into the heart via the PULMONARY VEINS and like the latter, they are the only veins that carry oxygenated blood.

The blood then goes back into the heart, emptying into the LEFT ATRIUM. From there it goes through the BICUSPID VALVE or MITRAL VALVE and to the last and thickest pumping chamber, the LEFT VENTRICLE. The left ventricle pumps the blood through the AORTIC SEMILUNAR VALVE which opens out to the AORTA.

And at last, it goes back to your body.

How is blood different after it is pumped through the capillaries in the intestines?

ololo11 [35]

Answer:

As blood moves through the capillaries, the oxygen and other nutrients move out into the cells. Then waste matter from the cells goes into the capillaries. As the blood leaves the capillaries, it moves through the veins. Veins merge into larger tubes to carry the blood back to the heart.

Which characterisic of life destinguishes a fire and a flowering plant

worty [1.4K]

Answer:

The correct answer from the options is Growth.

Explanation:

There are seven basic characteristics of life which separate living things from non- living things.

Growth is one of the characteristics which separate a living thing from a non- living thing. The plants use essential macromolecules for growing. The fire will not have macromolecules to grow. Hence, growth is the option that is correct.

Other options like defined boundary are incorrect because both plants and animals have a defined boundary.
