What role did scientific methods, such as communicating results, play in the discovery of the structure of dna?
nika2105 [10]
It played a very big role as without collaborative work from multiple scientists who were working on the discovery of DNA, it would have postponed its discovery by decades perhaps. For that reason - yes, communicating results played a major role in the discovery of the structure of DNA.

What limits where pikas live?
AnnZ [28]

"For years, the polar bear has been the symbol of the global warming movement. But today, the American pika has good grounds to compete with the polar bear for this unwanted honor.


American pikas are suffering because global warming has brought higher temperatures to their western mountain homes.


Pikas live in high mountain ecosystems that are cool and moist. Higher temperatures can cause the pikas to overheat.


Unlike other mountain species that can move to higher altitudes in warming climates, pikas live so high on the mountain that there is no where for them to go. Without our protection and help, American pikas could be the first species with the distinction of going extinct due to global warming. We can't let this happen!

Description

American pikas are small, rodent-like mammals. Although they look like a squirrel or guinea pig, they're actually more closely related to rabbits and hares. Pikas have short, stout bodies with big, round ears. They do not have a visible tail.


Pikas have brown and black fur. The fur is colored to camouflage with rocks. Pika fur is thick to keep them warm in the winter. During the summer, they put on a much lighter coat of fur--however, the fur is still thick enough that a pika might overheat if exposed to very high heat for long periods of time.


Size: Pikas are about 7-8 inches long.


Diet: Pikas are herbivores. They especially love grasses, weeds and tall wildflowers that grow in their rocky, high mountain habitat.


Pikas like to be prepared! In the winter months, there are a lot less grasses and flowers growing in the mountains. To prepare for the lean times, pikas like to save up food during the summer. A pika will collect a pile of extra wildflowers and grasses and lay them out in the sun. The sun's heat dries the plants so they do not get moldy. The plants are stored in the pika's den until winter.


Typical Lifespan: American pikas can live around 6-7 years. Many die after 3 or 4 years.


Habitat

American pikas are found in alpine terrain, above the tree line, on mountains. They live on rock faces, talus and cliffs near mountain meadows. Talus is a rocky area on the side of cliffs, slopes or hillsides.

Range: American pikas live on high-elevation cool mountains west of the Rocky Mountains. They can be found in Montana, Wyoming, Colorado, Idaho, Washington, Oregon, California, Nevada, Utah and New Mexico.


How Pikas Communicate

American pikas are often heard before they are seen. They make calls and sing to define and protect their territory, alert others to the presence of dangers and attract mates. The call sounds like the bleat of lamb, but more high-pitched and squeaky.


Life History and Reproduction

American pikas have adapted to living in very inhospitable environments. They live where most other mammals do not venture to go--the treeless slopes of mountains. It is very cold, rocky and treacherous for the tiny pika.


Pikas help protect themselves by living in colonies. They live near other pikas and will alert the group to predators by sending out a warning call. Weasels, hawks and coyotes can prey on pikas.


Although pikas live in colonies, they are very territorial over their den and surrounding area. They will give off territorial calls to define the boundaries between each pika neighbor. They make their dens among rocks.


Pikas are active in the daytime and they do not hibernate in winter. They are active throughout the year, but they tend to spend most of their time inside the den in the winter. Pikas eat stored grasses to survive and venture out to forage when the weather permits.


In early to mid-spring, American pikas begin to breed. Many pikas breed twice--once in spring and summer. The female is pregnant for a month before giving birth to a litter of 2-6 young. When born, the young cannot function on their own and they depend on their mother for care. It takes about a month for the young to be weaned and 3 months to reach an adult size. After a year, the young develop into breeding adult pikas.

why do saturated fatty acids have straight structures while unsaturated fatty acids have bent structures
Deffense [45]

1. Though Florida receives a lot of rainfall, only 1 percent remains available for people to use or drink. What happens to the r
telo118 [61]
<span>
1. Although the state of Florida receives a lot of rainfall, about 61 percent of that water leaves the ground by evaporation and transpiration, and another 38 percent is ‘lost’ into the Atlantic Ocean & Gulf of Mexico, thus leaving only 1 percent of the rainfall water available for drinking and other human use. 

 2. Florida has a very vast underground water system, known as the Floridan aquifer system; for this reason, Florida is the source of drinking water to four other states. These states are South Carolina, Georgia, Alabama, and Mississippi. The Floridan underground water system is made up of the Upper and Lower Floridan aquifers.

3. Residents of the state of Florida wanted to get rid of the water in certain areas of the state because there was too many wetlands, they experienced frequent flooding which posed a great measure of difficulty in navigating the state.

4. One negative result of the changes made by people in order to get rid of the ‘excess’ water in Florida was groundwater depletion which has led to the drying up of wells, decrease in water level in streams and lakes, reducing quality of water and land subsidence.

5. One thing that has been done to try and improve those mistakes is Rainwater harvesting; a method which is often used to replenish ground water. Using the rainwater harvesting approach, an outlet pipe is connected from the rooftop and used to divert the rainwater to existing wells.
