The same sentences are written with a substitution, deletion, or insertion, much as a gene may have a substitution, deletion, or
strojnjashka [21]

Answer:

The question is incomplete, the complete question has been added as an attachment.

THE DGR AN represents deletion mutation

THE RED ANA TRA N represents insertion mutation

THE FOX WTS RED represents substitution mutation

Explanation:

Mutation is a change in the nucleotide sequence of a gene. It can be of different types depending on how it occurs. A deletion mutation is that which involves the removal of one or more nucleotide base from the sequence.

An insertion mutation is the addition of one or more nucleotide bases to the sequence.

A substitution mutation is the replacement of one or more nucleotide base in a sequence.

The original sentences were:

1. THE RED ANT RAN

2. THE FOX WAS RED

3. THE DOG RAN

The three sentences that mutated/changed are:

1. THE DGR AN- in this sentence, letter O which represents one base is missing due to removal, making the original sentence (THE DOG RAN) alterated. Hence, this represents an example of deletion mutation.

2. THE RED ANA TRA N - in this case, Letter A has been added in between N and T. This makes the original sentence (THE RED ANT RAN) altered. Since addition of letter (base) occurred, this represents an example of insertion mutation.

3. THE FOX WTS RED - In this case, letter A in "WAS" was replaced by T, making the original sentence (THE FOX WAS RED) altered. Since a replacement of letter (base) is the case here, it represents an example of substitution mutation.

Describe the impact of human activities on natural resources;
Anastasy [175]

Answer:

As the human population has grown, the need for more land has caused an increase in the cutting down of forest lands for habitation and farming. The result has been an increase in soil erosion, an increase in species extinction from habitat loss, and a reduction of oxygen supplied by the trees, as well as lower amounts of carbon dioxide being removed from the atmosphere. Industrial and personal use of fossil fuels has dramatically increased the amount of air pollution in the atmosphere while systematically using up the supply of the non-renewable resources such as coal, oil and natural gas
