Answer:
1) 5 kingdom system of classification is a type of classification in which all the living organisms are classified into 5 kingdoms i. e. protista, monera, fungi, plantae and animalia.
2) Plants are autotrophic organisms while animals are heterotrophic. Plants have cell wall while cell wall is absent in animal. Plants are fixed while animals move from place to place.
3) Both plants and animals are made of cell. Both plants and animals are multicellular organisms. Both plants and animals reproduce.
4) Plants make their own food while fungi are unable to make their own food. Plant cell wall is made of cellulose while fungi cell wall is made of chitin.
Answer:
The correct answer is: exonuclease activity.
Explanation:
DNA Polymerase is an enzyme of critical importance for the replication of the DNA. DNA needs to be replicated so, when entering Mitosis, each daughter cell can have a copy of the genetic material they need.
DNA Polymerase has an exonuclease activity in which mismatched nucleotides are removed from the newly replicated DNA strand in order to prevent mutations that can lead to malfunctioning or harmful proteins.
Yes, sure!
1) Moving Water - Water, when running for a long period of time, can actually start to weather rocks.
2) <span>Ice wedging - Yep, this can cause rocks to weather as well. Water, when being constantly frozen and unfrozen weathers the rock due to the fact that water is able to expand.

3) Plant Roots - Ah, these little nutrient grabbers can certainly weather rocks over periods of time.
4) Winds - Winds can certainly physically weather the rocks, and it's probably the most common way they do.
