Answer:

The largest mass extinction ever recorded on earth was that which occurred at the end of the end of the Permian period.

Explanation:

The largest mass extinction of species ever recorded on Earth, which occurred 252 million years ago and eliminated 96% of marine fauna, occurred at the end of the Permian period and was the result of global warming and left the animals of the oceans without sufficient oxygen to survive.

The lack of oxygen caused by global warming explains more than half of the loss of marine diversity in this late Permian mass extinction and other factors, such as acidification or changes in the productivity of photosynthetic organisms, acted as additional causes, according to these scientists.

The situation at the end of the Permian, when the increase of greenhouse gases in the atmosphere generated higher temperatures on Earth, is similar to the current one.

Please let me know !! ASAP PLS

Answer:

$AD = 8$ , $DC = 15$ , $m\,\angle A = 112^{\circ}$ , $m\,\angle B = 68^{\circ}$ , $m\,\angle C = 112^{\circ}$

Explanation:

If the quadrilateral presented in figure is a parallelogram, then the following conditions are satisfied:

$AD = BC$ (1)

$AB = DC$ (2)

$m\,\angle D = m\,\angle B$ (3)

$m\,\angle A = m\,\angle C$ (4)

$m\,\angle A + m\,\angle B = 180^{\circ}$ (5)

$m\,\angle C + m\,\angle D = 180^{\circ}$ (6)

If we know that $m\,\angle D = 68^{\circ}$ , $AB = 15$ and $BC = 8$ , then we have the following results:

$AD = 8$ , $DC = 15$ , $m\,\angle A = 112^{\circ}$ , $m\,\angle B = 68^{\circ}$ , $m\,\angle C = 112^{\circ}$

Misha Larkins [42]

Answer:

"Dr. Randall Irmis is a famous paleontologist, who has gone on to make important discoveries since he showed the Penn State CAUSE class this fossil plate from the armored vertebrate Buettneria."

Explanation:

<u>Based on the discussions in the textbook and lecture on the topic of evolution, it is likely that: </u>

All species alive today are completely unrelated to Buettneria.
Some species alive today are essentially identical to Buettneria.
The most similar species alive today are related to but recognizably different from Buettneria.

I think the answer is B.

Because one of the factors that has prevented it from being a more unified country is its geography. It's rugged, mountainous. It's very difficult for any invading army to develop or control it.

Nuclear experimentation is a major global issue that affects relationships between countries. Describe why countries try to limi

Fynjy0 [20]

Answer:

Nuclear testing is known to cause an abundance of environmental pollution. It also causes one to have intense skin burns and evolve acute radiation syndrome. In some cases even cancer and cardiovascular disease can develop, if exposed to nuclear radiation. These are a few of the reaons why countries try to limit their use of nuclear weapon testing. Keeping the people and environment healthy is their main concern.

(Hope this helped :)
