Answer:
The conservation of “junk DNA” sequences in diverse genomes suggests that they have important functions.
Explanation:
Transposons move by means of a DNA intermediate, whereas retrotransposons move by means of an RNA intermediate.
It helps sustain tbe population because of the food chain. everything needs to eat, so the more diverse a population is, the more options things have to eat. The population is sustained because everything is able to eat to survive
During respiration, the diaphragm moves upwards and returns to dome shape from the flattened shape before during expiration.
This movement of diaphragm can decrease the lung volume, increase the pressure inside and thus force the air out. This process is expiration.
However, if we breathe in again, which makes that inhalation, the diaphragm moves downwards into a flat shape so that it can increase the lung volume and thus we can breathe in as much air we can. This process is completely opposite from expiration.
