Dna polymerase i and dna polymerase iii both have but only dna polymerase i has 5'–3' polymerase activity; 3'–5' polymerase activity 5'–3' exonuclease activity; 3'–5' exonuclease activity 3'–5' exonuclease activity; 5'–3' exonuclease activity 3'–5' polymerase activity; 5'–3' polymerase activity 5'–3' polymerase activity; 3'–5' exonuclease activity

1) 5'-3' polymerase activity

2) 5'-3' exonuclease activity

Explanation:

Both enzymes act during DNA replication in prokaryotes.

DNA polymerase I is in charge of removing primers (5'-3' exonuclease activity) and completing those free spaces with DNA (5'-3' polymerase activity).  

DNA polymerase III is the main enzyme in charge of DNA elongation (5'-3' polymerase activity) with also proof reading activity (3'-5' exonuclease activity).

With this in mind we can complete the sentence:

DNA polymerase I and DNA polymerase III both have 5'-3' polymerase activity but only DNA polymerase I has 5'-3' exonuclease activity.

explanation:

plate tectonics and volcanic euptions

over time, plate tectonic processes cause continents to move to different positions on the globe.

for example, britain was near to the equator 300 million years ago, and therefore was hotter than it is today. for further details look at our climate through time poster or online map.

the movement of the plates also causes volcanoes and mountains to form and these too can contribute to a change in climate.

mountain ranges formed by plate tectonics. large mountain chains can influence the circulation of air around the globe, and consequently influence the climate.   warm air might be deflected somewhere cooler by the mountains.
