Why do you think these fossils are important to the study of evolution?

Fossils best demonstrate what ancient organisms may have looked like when they lived long ago. Without fossils, knowing such things would be nearly impossible.

Somebody knows the answer to this
KiRa [710]
Typically when we think about extreme weather, we think about the effect of weather on humans and other life forms. However, weather events also greatly impact non-living things. Freeze and thaw cycles tend to break up rocks, weathering them physically. Landscape erosion can be greatly enhanced by storms because rivers and streams are able to transport larger amounts and larger sizes of material than they otherwise would, due to faster flow velocities. Sand at beaches is carried away by strong storms until it can be replenished over time. Sediments become hydrated during rainfall events, which can result in landslides and land movement. Many of these processes can create hazards for humans, but the physical landscape is very much shaped by extreme weather events. Weather is weather, which is nonliving. Erosion is affected by weather, the more rain there is, the more erosion. The more temperatures change, the more erosion because things swell as they warm up and shrink as they cool off, which can cause them to break.


Hurricane affects come from both wind and water impacts. Wind and waves break coral, damaging it or forcing it on shore and disrupting the ocean ecosystem. Fish and benthic organisms face turbulent conditions due to waves and wind. ... Winds dislocate sea and migratory birds caught in the eye of the storm.


Some examples of non-living things include rocks, water, weather, climate, and natural events such as rockfalls or earthquakes. Living things are defined by a set of characteristics including the ability to reproduce, grow, move, breathe, adapt or respond to their environment. Extreme heat causes lakes and rivers to dry up. Some kinds of earth can also dry up so much that it gets cracked.

Extreme rainfall causes floods and landslides.

Extreme cold can cause rocks to break, when the water that leaked into cracks in the rock freezes and expands.

If I knew more about the water cycle, I might be able to tell you more about how extreme weather affects clouds and other parts of the water cycle.

Ras is a GTP-binding protein involved in cell proliferation (division). In its active form, with GTP bound, Ras activates cell s
ArbitrLikvidat [17]

Answer:

E. They decrease the rate at which Ras hydrolyzes GTP.

Explanation:

Activated Ras has GTP bound to it, this propagates an intracellular signal to the nucleus where cell proliferation is induced. Thereafter proliferation is switched off by the hydrolysis of the bound GTP to GDP.

Therefore decreasing the rate of GTP hydrolysis causes Ras to remain active, ultimately leading to uncontrollable proliferation characteristic of cancer.

What would happen if (G) guanine lined up with (T) thymine during meiosis. Please help me with this.
ivann1987 [24]

Answer:they won't for a pair

Explanation:Basically it all depends on process called complementary base pairing, the structure of thymine and adenine is such that it forms two hydrogen bonds and therefore pair up

2.guanine and cytosine have such structure that they form three hydrogen bonds and pair up

So Adenine complements only thymine and guanine complements cytosine and there aren't any chances of guanine pairing up with thymine.
