Answer:

TEs are repetitive and mobile elements, thereby it is hard to trace their origins  

Explanation:

Repetitive elements are patterns of nucleotide sequences in the DNA characterized to have multiple copies throughout the genome. DNA mini-satellite and Transposable Elements (TEs) are some examples of highly repetitive DNA. TEs are repetitive mobile elements that have the ability to jump within the genome and occupy a major part of eukaryotic genomes. For instance, there is a type of TEs called retrotransposons which mobilize through a copy-and-paste mechanism, thus increasing their number in a genome. In consequence, TEs represent highly repetitive and dynamic genomic sequences, and thereby it is hard to trace their evolutionary histories.

How were humans made
nignag [31]
There are different ideas of how humans came to be, depending on if you’re going from a scientific or religious point of view.

For instance, scientifically, humans evolved from Chimpanzees. This is further supported by similar genetic make up as well as intelligence an actions.

Religiously, Christianity specifically, states that humans were made by God - specifically Adam and Eve.

Different perspectives, different answers.

However, if you’re asking for human make up, start with the basics of atoms and go up through layers of systems.

Hope this helps!

Drag each tile to the correct location on the table,
Tom [10]

Answer:

Mechanical Isolation

A snail with a flat disc-like shell

will not be able to mate with a

snail having a conical shell.

The reproductive organs of

male bush babies do not

match with the reproductive

organs of females of other

bush baby species

Behavioral Isolation

The mating call of a cricket is not

recognized by a cricket of other

species.

The signals sent by a male firefly

are not recognized by the female

firefly of other species.

Explanation:

Mechanical isolation occurs in the scenario where two organisms are willing to mate but cannot do so due to the physical challenges. As in the case of snail a flat disk and a conical disk snail are willing to mate but physical barriers restrict them in doing so.

The same case is with the male and female bush babies where the difference in reproductive organs does not allow them to mate.  

Behavioral isolation represents a scenario where two organisms are unaware of mating rituals, season, pattern or signals of each other and hence cannot mate.  

For example – male and female cricket do not recognize the mating call of each other. Likewise male and female firefly is also not able to understand each other’s mating signal.
