Answer:

Fossils of Ambulocetus

Explanation:

Fossils of Ambulocetus show that it was about 3 meters long. It had hind legs which were more suited for swimming than for walking. It could hear very well under water, and its teeth resembled those of modern cetaceans. Its limb anatomy suggests that it was slow on land and in the water.

1. How would the predation of pythons on rabbits affect the population of other large predators such as bobcats and alligators?
Inessa [10]

Q1:

Answer:

Studies have reported that due to predation of pythons on rabbits, the population of other predators is badly affected.

Bobcats are a natural predator of rabbits thus they come in a competition with pythons for food. As pythons are more powerful so they target rabbits more easily than Bobcats. The population of Bobcats has been declined by 90% or more due to the establishment of pythons in the Everglades.

<em>Alligator mississippiensis </em>or American alligators are also abundant in Everglades and just like Bobcats they compete with pythons for their food. They can even kill pythons if pythons are smaller in size than them, but python will kill alligator if he is of smaller size. Although rabbits are food for both alligator and Python but Alligator is a key stone specie and it has very important ecological role, because it digs holes in land that retain water upon rainfall. These water hole provide water in the extreme dry weather and help in survival of other small specie like insects and birds.

So, we can expect the population of Alligator, Bob cats and other small insects and birds to decline rapidly if Python population kept on increasing with same speed.

-------------------------------------------------------------------------------------------------------------

Q2:

Answer:

There is no doubt that Pythons pose serious threat for both humans as well as survival of other organisms like Alligators and birds. However, I donot think that “Python challenge” is a reasonable way to kill or remove Pythons. Because It can threat the lives of many individuals who take part in competition, although they are trained but still they are nor professionals and get training of only few weeks so it is not safe competition.

There should be some strategy of introducing natural predators like Brown beers, Cougars and Alligators which can kill python naturally without staking the life of humans at risk.

Which is a correct interpretation of the cladogram shown below?
nataly862011 [7]

A cladogram is an image or a diagram that shows us an evolutionary relationship between different organisms. Up at the top we find the different organisms and their names. Along the side is where we find their characteristics. Anything that is past each characteristic will have that characteristic as you move up the cladogram. This diagram also shows which organisms are most closely related to one another.



Please see the image for an example. In this example we can see that the Koalas evolved after the trout.



I hope this helps, Regards.

1.how is the sound of thunder created?
Naddik [55]
1. Thunder is caused by the rapid expansion of the air surrounding the path of a lightning bolt. ... From the clouds to a nearby tree or roof, a lightning bolt takes only a few thousandths of a second to split through the air. The loud thunder that follows the lightning bolt is commonly said to come from the bolt itself.
2. thunderstorms mostly occur in rainforests. Some of the most powerful thunderstorms happen in the United States of America.

3. Cumulonimbus is a dense, towering vertical cloud, forming from water vapor carried by powerful upward air currents. If observed during a storm, these clouds may be referred to as thunderheads. Cumulonimbus can form alone, in clusters, or along cold front squall lines.

4. The air cools as it rises. Water vapor condenses and forms cumulus clouds. When condensation occurs, heat (latent heat/energy ) is released and helps the thunderstorm grow. At some point, condensation high in the cloud (now in the form of water droplets and ice) falls to the ground as rain.

The _________________ is composed of and endothelial layer that is continuous with the endocardium of the heart.
hram777 [196]

The t<u>unica media</u> is composed of an endothelial layer that is continuous with the endocardium of the heart.

<h3>What is tunica media?</h3>

Collagen, elastin, and smooth muscle cells make up tunica media. It is located halfway between the tunica externa and the tunica intima. The transverse arrangement of its strands and color make the middle coat (tunica medium) distinct from the inner (tunica intima). It not only supports the vessel but also alters the vessel's width to control blood pressure and flow.

Elastic fibers make up the majority of the tunica media in bigger vessels. The number of elastic fibers reduces as arteries get smaller, whereas the number of smooth muscle fibers grows. The strongest of the three layers is the tunica adventitia, which is the top layer. Elastic and collagenous fibers make up its structure.
