Answer:

whales in the wild, show two basic methods of sleeping: they either rest quietly in the water, vertically or horizontally, or sleep while swimming slowly next to another animal. They feed through the extreme mechanism of engulfing as much prey-laden water as they weigh and then filtering out the tiny krill it contains. ... When krill density increased, they began "lunge-feeding" more frequently, consuming more per dive to obtain as much energy from the krill as possible.

How did Jolade learn photography?<br>​
laila [671]

Jolade learned photography by studying at the University. He studied classes of film and production, which included principles of photography and illumination.

> We are talking about London-based photographer Jolade Olusanya.

> In those early years as a student, photography was basically a hobby.

> He was interested in sharing photographs on social media.

> He increased his interest when Inst*gram appeared.

> Jolade realized that although many people shared non-sense daily photos, a few shared artistic photographs.

> That motivates Jolade to take his Canon camera and starting to take more elaborated and artistic photos.

We can conclude that although your question had no context or references, we did deep research and could find Jolade began his activities as a hobby, and from that amateur beginning he became a renowned photographer in England.

How did the explosion affect the ship​
Stolb23 [73]

Answer:

What was the cause of the USS Maine explosion?

Explanation:

Initial reports concluded that Maine had been sunk by a naval mine. Sparking a wave of outrage across the United States, the loss of the ship helped push the nation towards war. Though a later report in 1911 also concluded that a mine caused the explosion, some began to believe that it was the result of a coal dust fire.

How were the ideas of President Roosevelt and John Muir different regarding protecting the environment?
Natalija [7]

The Roosevelt Museum of Natural History opened its doors in 1867. Among its first specimens was the skull of a seal that had washed up in New York Harbor, begged from its owner by the museum's founder, eight year old Theodore Roosevelt, Jr. Frail, myopic "Teedie," as he was known to his family, seemed an unlikely naturalist. But it was his mind, not his body, that made Roosevelt's precocious entry into the world of natural history anything but child's play. Inquisitive and single-minded, he would pursue his interests in nature relentlessly for the rest of his life -- a pursuit that would impact America's wild places for decades beyond his death.  

Fueled by Theodore's curiosity, the Roosevelt museum grew. Teedie collected everything within his reach and range of vision, and begged friends and family to bring him any specimens they found. He even paid other children to collect specimens for him. Yet he generously shared his collection. In 1871, he donated several specimens to another fledgling museum -- the American Museum of Natural History, which had been co-founded by his father.

The following year, having obtained spectacles to correct his vision and a shotgun to aid in capturing specimens, Theodore traveled with his family to Egypt and Syria, where he collected numerous birds. By then a skilled taxidermist, he skinned and mounted the birds himself. If young Roosevelt's collection methods seemed bloody and cruel, he merely followed the accepted practices of the leading naturalists of the time. Killing was the only way to make extremely accurate observations about the physical characteristics of unfamiliar animals.

While written in a childish hand, the notebooks in which young Roosevelt logged his studies reflected the zeal with which he pursued Nature. They contained complete descriptions of the animals collected, including size, sex, place and date collected, habits, and even stomach contents. In Vienna, where the family traveled after leaving Egypt, Roosevelt turned his hotel room into a virtual zoological laboratory, much to the dismay of the cousin who shared his lodgings.

At Harvard, where he studied natural history, Roosevelt similarly outfitted his off-campus apartment and continued collecting. In 1882, after being elected to the New York State Legislature, Roosevelt donated the bulk of the Roosevelt Museum of Natural History to the Smithsonian Institution. But his interest in the outdoors did not end with the museum's closing.

By the mid-1800's, many of the people closest to nature had come to realize that the wilderness could only suffer so much exploitation. Hunters, miners, and timber cutters threatened not only individual species, but entire ecosystems. Fortunately, forward-thinking sportsmen began to organize for the conservation of game and game habitat. Theodore Roosevelt, an avid hunter, joined the fight. Not surprisingly, the organization he helped to found would be among the most influential.

In 1887, Roosevelt and editor George Bird Grinnell of "Forest and Stream" magazine founded the Boone and Crockett Club. In the pages of his magazine, Grinnell had called for scientific forest management, clean water, and restricted use of natural resources-ideas considered quite radical by most Americans. Under Roosevelt and Grinnell, the Boone and Crockett Club would support these concepts, not only promoting the enjoyment of hunting, but the study and preservation of game animals and their habitats.

Perhaps none of the club's efforts was more significant than one of their earliest -- the battle for Yellowstone. While Yellowstone had been officially designated a national park, the designation included no provision for its protection from commercial exploitation. When mining and railroad interests threatened to seriously damage the park, Boone and Crockett rose to the defense.  

With editorials, speaking engagements, and furious lobbying among Washington's rich and powerful, the B & C succeeded. In 1894, President Gover Cleveland signed a bill protecting Yellowstone. While this action alone might have been enough to enshrine Theodore Roosevelt as a Friend to Nature, it represented only a fraction of what he would do to preserve the natural world. Roosevelt's career as a politician/conservationist had only begun.

Roosevelt the President is almost universally remembered for his brash foreign policy. Yet Roosevelt the naturalist also lived in the White House. During his tenure, with the same type of bullishness as he exhibited in the international arena, he established a natural empire the like of which the world had never seen.
