Compare and contrast ectothermy and endothermy, including their pros and cons.
spin [16.1K]

Endothermy is just another word for the term "warm-blooded" and ectothermy is closest to the meaning of "cold-blooded." The obvious pros of endothermy is the ability to perform more activities within a larger range of temperatures. For example, a human would be able to walk around in 100 degree weather Fahrenheit. They would probably be sweating a lot to maintain body temperature and would require lots of water, but they could do it. In contrast, a Lizard would most likely be forced to stay in the shade under a rock or another place as they have no system for maintaining their body temperature, and thus would have to wait until the environmental temperature cooled down before they could find food or move around. The cons of endothermy is it requires a lot more energy for an organism to maintain homeostasis, which is also a pro of ectothermy as lizards and similar ectothermic organisms can utilize more of their energy to d food or move around. Hope this helps!

Compare the thickness of the right and left ventricles. Which ventricle is thicker the right or left. Explain the difference.
zepelin [54]

Answer:

When comparing the thickness of the heart's ventricles, the left one is thicker than the right one, because it must generate more pressure to pump blood throughout the body.

Explanation:

In the human heart, the right ventricle is in charge of pumping the blood to the lungs —initiating the minor circuit of the circulation— while the left ventricle is in charge of pumping the blood to the whole body.

To fulfill its function, each ventricle has a specific thickness in its walls, the left one being thicker than the right one.

  • <em>The </em><em>right ventricle</em><em> is a chamber that handles more volume than pressure, and its walls are thinner because it does not require much pressure to pump the blood to the lungs. </em>
  • <em>The </em><em>left ventricle has a thicker muscular wall </em><em>because it is a chamber that must generate a high pumping pressure, so its contraction force must be greater. </em>

The structure of the myocardium in the heart is what allows each chamber to fulfill its function adequately.

The decrease in native birds will be due to the increased competition for food. They may adapt to different foods; however, the initial and most prominent effect will be that of the native birds' population declines.

How do astronomers measure distances to stars?
a_sh-v [17]

Answer:

I found this online:

Astronomers estimate the distance of nearby objects in space by using a method called stellar parallax, or trigonometric parallax. Simply put, they measure a star's apparent movement against the background of more distant stars as Earth revolves around the sun.
