Answer:

Scientists believe that at first these bears scavenged seal carcasses that had washed ashore, and gradually began to hunt the seals by waiting at the water's edge as the seals surfaced to breathe. This is believed to be an important step in the evolution of a new bear species, the polar bear

Over time the new polar bears were used to the cold climate and learnt how to fish, they then separated from the grizzly bears, they developed new creatures which would help them survive in one of the most dangerous climate.

Answer:

cess for GE crops conducted by the U.S. Environmental Protection Agency (EPA), the U.S. Department of Agriculture (USDA), and the U.S. Food and Drug Administration (FDA). Other evidence came from studies published by regulatory agencies in other countries or by companies, nongovernmental organizations (NGOs), and academic institutions. The committee also sought evidence from the public and from the speakers at its public meetings and webinars.1

The committee thinks that it is important to make clear that there are limits to what can be known about the health effects of any food, whether non-GE or GE. If the question asked is “Is it likely that eating this food today will make me sick tomorrow?” researchers have methods of getting quantitative answers. However, if the question is “Is it likely that eating

Commercial jets fly in the lower stratosphere. How does the jet's exterior temperature change as it leaves Earth's surface and e
LUCKY_DIMON [66]

The correct answer is option B

In the lower stratosphere, ozone is found which consists of unusual type of oxygen molecule which cause heating of this layer due to the absorption of ultraviolet radiation. The temperature rises as we move upward in the stratosphere. This causes temperature stratification due to which the convection and mixing is reduced and the layer of air becomes stable. Since the air is stable, the jet aircraft flies in the lower stratosphere to avoid disturbance and turbulence.
