Answer:

Endocardium

Explanation:

The endocardium makes the innermost lining of the wall of the heart. It is present over the thin layer of connective tissue. The function of the endocardium is to provide a smooth lining for the chambers of the heart. The valves present in the heart also have endocardium. The dense connective tissue of the heart valves is covered by endocardium.

The presence of the smooth endocardium made up of endothelium reduces the surface friction as blood passes through the heart. The endocardium of heart chambers is continuous with the endothelial lining of the large blood vessels that are attached to the heart.

Which level on on the pyramid will have the most amount of energy?
serious [3.7K]

Answer:

<em>Hello, In all the ecological pyramids, producers (organisms that produce their own food) are found at the lowest trophic level. This trophic level contains the highest amount of energy. The energy in each trophic level of an energy pyramid is just 10 percent of the energy in the level below it. (Why is there less energy available at the top of an energy pyramid than at the bottom?) Less energy is available to organisms in the upper levels because each organism releases some of the chemical energy in food to the air as thermal energy. Less total energy is available with each step up energy pyramid. Hope That Helps!</em>

Stella [2.4K]
The correct answer is a dichotomous key. Basically, you use the key to decide what species an organism is by looking at what traits it has, and if it doesn't have some traits you can instantly rule out a large number of species which brings you closer to your answer of what the species is that you're looking at.
