Answer:
C. All fossils contain intact DNA that can be sequenced.
Explanation:
Fossils are the impression, trace or preserved remains of once-living thing from past thousands of years such as bones, exoskeletons, objects preserved in amber, and stone imprints of animals or microbes.
Fossils provide evidence about seevral characteristics and features of extinct organism such as evolutionary relationship between organisms and transitional forms between groups of organisms. but all the fossil do not provide evidence about the intact DNA that can be sequenced because some fossils carry DNA rumnants which do not have the ability to get sequenced.
Hence, the correct option is C.
The speed of a longitudinal wave will not be affected by the temperature of its surrounding. Base on the formula for the wave speed (applicable on longitudinal wave), wave speed ( speed in m.s 2) is equal to the distance of a wave (wavelenth in meter) travel over a unit of time (seconds) or wave speed is equal to distance of a wave times the frequency (hertz), temperature is not included in calculating the wave speed.

<span>This is a great question and I would love to hear what a roller coaster designer / engineer thinks makes a successful roller coaster. Until they show up, though, you've just got me.For me a successful roller coaster is one that fills me with dread as it makes the slow climb up the track, and then converts that dread into pure adrenaline as it takes me down and around. It's the one that makes your stomach drop as you're in freefall and makes your heart skip a beat as you take a corkscrew loop. Some roller coasters are open at the bottom so your legs dangle off. Some go backwards through a corkscrew. Those are fun additions.What I'm saying is that a good roller coaster is one that floods you with emotions as you're riding it - think about the Mummy ride at Universal Studios. It's not a particularly crazy coaster as far as thrill rides go, but the design of the ride itself is meant to fill you with anxious dread as you wait for something to happen and then launches you at breakneck speed when you least expect it. That's a good roller coaster, and I'm not even sure you'd actually call it a roller coaster.Well that's me ^.^ I hope this helps</span>
The answer is 40 m, because you must cross multiply by using proportions.
