Answer:

The correct answer is - Cyanobacteria; Horizontal gene transfer

Explanation:

According to the endosymbiotic theory it is believed that the eukaryotic plastids (mitochondria and chloroplasts) have developed from symbiotic bacteria, such as cyanobacteria and alpha-proteobacteria.

During this symbiotic process, some genetic material may have been move in between the symbiotic counterparts in a process called Horizontal gene transfer or lateral gene transfer.

thus, the correct answer- Cyanobacteria; Horizontal gene transfer

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.
