Which of the following terms best relates to the mechanisn that flatworms use to obtain oxygen pharynx diffusion spiracles excre

bagirrra123 [75]

Flatworms absorb oxygen by diffusion mechanism through their skin to the cells in their bodies. Since flatworms do not have a circulatory system, their bodies' cells are positioned close to the skin to ease the uptake of oxygen from surrounding fluids or water.

a. Blood enters the right ventricle from the right atrium through the right atrioventricular valve which is also known as the tricuspid valve

d. The right ventricle contracts next, which forces blood up through the right semilunar valve which is otherwise known as the pulmonary valve .

e. After circulating through the pulmonary capillaries, the blood returns to the left atrium. 

f. From the left atrium, blood moves through the left atrioventricular valve which is also referred to as the bicuspid or mitral valve.

b. From the left ventricle, the blood is pumped up to aorta the through the left semilunar valve which is sometimes referred to as the aortic valve.

Which of the following is not a true statement comparing exoskeletons and endoskeletons?

nordsb [41]

Answer:

Exoskeletons provide less mechanical leverage.

Explanation:

There are two types of skeleton in living beings: the endoskeleton (which vertebrates possess, is lined with epithelial tissue and has bones and cartilage) and the exoskeleton, a skeletal structure that is located outside the body of the living being. , is an external skeleton. They are common in invertebrate animals, which have no internal bone structure.

The exoskeleton is a tough but flexible outer layer, not formed by bones, unlike the vertebrate endoskeleton. Its function is mechanical, chemical and biological protection, avoid excessive water loss, muscle support and serves as a connecting point for legs, wings and other appendages. However, this type of skeleton provides less mechanical leverage.

On the other hand, the endoskeleton is the name given to the internal skeleton, which is inside the body. This body structure is mainly seen in vertebrate animals and has the function of supporting and moving the body, as well as protecting some internal organs. Unlike exoskeleton, the endoskeleton provides more mechanical leverage.
