PLEASE HELP!! im despratte
Alex73 [517]

Answer:

Template strand = complementary strand

GCA AG = CGT TC

TTA CG = AAT GC

GAT AC = CTA TG

CGG AT = GCC TA

DNA strand = mRNA strand

CGA TT = GCU AA

GCT TA = CGA AU

GCA TC = CGU AG

TTC AT = AAG UA

It is more important for DNA replication to be exact than transcription or translation because any error that occurs during DNA replication if not repaired will become permanent and will be transferred to the next generation.

Explanation: In DNA base pairing, G pairs with C and T pairs with A. But in RNA base pairing, G pairs with C and U pairs with A. DNA contains four bases G, C, T and A while RNA contains four bases G, C, A and U.

What would life be like without plate tectonics
emmasim [6.3K]
 It really is impossible to predict such a matter. I mean, think about it, its nearly impossible to think about how earth would be impacted if the heat from the interior of the planet that powers plate tectonics were to suddenly cease to exsist, or if that heat never exsisted in the first place, because that is how planets are formed.
 One thing is certain however, life wouldn't be the same without plate tectonics; in one case, the constont transgression/regression, sue in large part of tectonic forces acts as a evolutionary pump forcing life to evolve. EXAMPLE:  the evolution of plants from marine to terrestrial settings. Without plate tectonics, life would certainly be dramatically different.

Colton has an ice cube that has a mass of 4 grams. He places it in a sealed container and then puts it in the microwave on high.
Jobisdone [24]

Hello!

The sentence that best describes what Colton discovers is D) The mass of the melted ice cube remained the same at 4 grams.

<h2>Why?</h2>

The melting of the ice cube is a physical process. That means that it is a process in which the identity of the substance (water) doesn't change, but only how their molecules are arranged.

In melting, a substance in the solid state changes to the liquid state. Its molecules go from having a definite volume and shape to having the same shape as the container that holds it, but there are no changes in the mass of the substance.

If the container is closed, Colton should record the same mass as the initial one, as mass doesn't change in physical processes.

Have a nice day!
