How could the movement of tectonic plates create another supercontinent like Pangaea

Margaret [11]

<span>When the landmasses are again collected together in a specific area

The Pangea theory supports the theory of plate tectonics because it is based on the idea that all the present continents were one super-continent. For reasons still unknown, the super-continent got separated and created separate smaller continents. This theory also supports the fact that this movement will continue until the day arrives when all the smaller continents will again merge in a different configuration to create another super-continent. </span>

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.

PLEASE HELP !Unlike sexual reproduction, vegetative reproduction

pishuonlain [190]

B. requires flowers.

Sexual reproduction is one type of biological reproduction wherein the genitals of the male and female organisms engage into a sexual activity in order for the sperm cells to fertilize the egg cells of the females.
In the case of most plants, they engage in asexual reproduction. Asexual reproduction happens outside the body system of a cell.
Moreover, this process is extrinsic than its opposite the sexual reproduction which happens in the female reproductive system.

With the given dimensions, it is important to note that the space shuttle is still in need of the two solid rockets because it has to be propelled in the outer space at specified speed which is only attainable if there has been initially a force applied to it prior it is sent to the outer space.
