Answer:
A new rock is produced that is different from the original rock.
Explanation:
During chemical weathering, a new rock is produced that is different from the original rock.
- Chemical weathering is the chemical decomposition of rocks to form sediments and soils.
- A large chunk of rock combines with water, air and other chemical materials.
- This cause chemical action and a new substance is produced.
- This process is known as chemical weathering.
Physical weathering is the breaking down of rocks into smaller fragments.
Answer:
Explanation:
Mutation can cause a change in DNA to change in many ways.
Mutation is the sudden change in the genome of an organism that can be heritable from parent by their offspring.
Missense mutation - This occur when a base pair is substituted for by another leading to the formation of an entirely new amino acid.
Nonsense mutation - This occurs when a base pair is substituted for by another leading to the formation of a new amino acid. The new amino acid form therefore send a stop signal to the sequence of amino acid been built.
Insertion or deletion - Insertion mutation inserts new base pair into the sequence changing the number of the DNA base while deletion deletes a base pair changing the number of DNA base from the amino acid sequence.
