When a dolphin jumps, it moves its muscles and chemical potential energy is converted to kinetic energy. Some of this energy is

lost to the dolphin. Explain why this phenomenon does not violate the Law of Conservation of Energy.
The dolphin is a closed system, so energy is allowed to exit the system.
The energy is transferred to waves in the surrounding water.
The muscles recapture the energy when they relax after contractions.
The Law of Conservation of Energy does not apply to biological systems.

I would say the answer is either A or B, the Law of Consevation of Energy states that,"<span>the total energy of an isolated system remains constant</span>" so this energy isn't destroyed, it's simply useless. When we use energy to run, our energy is released as heat, so I would assume that it is the same for other creatures. Let me know if this helps.

the answer is B.) the energy is transferred to waves in the surrounding water

Using the data from the graph, explain the relationship between the population of snowshoe hares and the population of the lynx.
AnnyKZ [126]

As you already know, lynx are predators of hares and a balance between the populations of these two animals is necessary, so that the populations have a stable growth.

As you can see in the chart above, when the lynx population is very low, the hare population is high. This is because, as there are few lynxes, predation is low and hares are able to maintain their birth rate higher than the mortality rate. However, there are many hares available for lynx to feed on, which allows the lynx's birth rate to also be higher than the mortality rate, which causes the lynx population to grow.

Also according to the graph, you can see that as the lynx population grows, the hare population decreases. This is because the greater number of lynx causes predatorism to increase and hares are hunted by lynx in greater quantities. This causes the mortality rate of hares to be higher than the birth rate, which decreases its population. On the other hand, the abundance of food allows the lynx population to grow to some extent. This is because, as you can see in the graph, when the hares population is very small, the lynx does not have enough food, which causes an increase in the mortality rate, also decreasing the lynx population.

When the lynx population is low, predatorism is lower, which allows hares to reproduce by increasing their population, which will result in an increase in the lynx population.

Why are volcanoes so important to geologists?
Kaylis [27]
The location and types of volcanoes are related to plate tectonics as well, so in that sense volcanoes also help us to understand about the tectonic history of a region because if there are volcanoes someplace even if they're not currently active we know that that must have been some sort of a plate uwu

Which statement concerning osmosis and active transport is correct?
marshall27 [118]

The question is incomplete, however, the statements associated with this question is given in the comments and here as well:

Neither facilitated diffusion nor osmosis requires cell energy.

Diffusion of gases and other small molecules requires no energy on the part of the cell.

Active transport requires cell energy and osmosis doesn't.

Both endocytosis and active transport require cell energy.

Answer:

The correct answer is - Active transport requires cell energy and osmosis doesn't.

Explanation:

Osmosis is an example of passive transport as it does not require energy to facilitate the movement of solvent In the process of osmosis,. It moves from high concentration to low concentration through the semipermeable membrane which is along the gradient so no requirement of energy.

In the case of Active transport, it requires energy to facilitate the movement of transport as it is the movement of a substance from low concentration to a high concentration area that is against the concentration gradient.
