Answer:
Orca inhaled oxygen and exhaled carbondioxide just like humans and other mammals.
Orcas is a type of whale which breathe air through their lungs not gills. They can't inhale oxygen from water, it comes to the surface in order to inhale oxygen and exhale carbondioxide.
In Orca breathing is not an automatic reflex but a conscious act due to the environmental condition. When orcas come to the surface to breathe they must quickly expel the carbondioxide gas and inhale oxygen into the lungs so we can conclude that Orca breathe just like humans and other mammals.

Explanation:
Observation is essential in science. Scientists use observation to collect and record data, which enables them to construct and then test hypotheses and theories. Scientists observe in many ways – with their own senses or with tools such as microscopes, scanners or transmitters to extend their vision or hearing
Answer:
The answer to your question is: Active transportation
Explanation:
Cell can move molecules in or out of it by two processes: Active or Passive transport.
Active transport: is the movement of molecules against a concentration gradient. Use proteins or enzymes to happen.
Passive transport: is the movement of molecules or ions from a higher concentration to a lower concentration.
The two ways by which we can detect that gene editing have occurred in the bacteria are;
A) WESTERN BLOT; Here,the gene that is edited will not be able to synthesize the protein.With this,if we do western against the already edited protein,no band will eventually appear in the western blot,and this indicates/confers that the gene have been edited.
B) PCR FOLLOWED BY SEQUENCING; IN PCR,there is amplification of the region with the use of flanking end primers that is edited.
However,mean primers will actually be used in a way that one primer is upstream to site of editing and the other primer to the downstream.
From this stage,the PCR product that is amplified will be sent for sequencing,and this sequency result will further confirm if the gene has been edited or not edited.
Restriction enzyme can also be used if the place where the gene has been edited is known.
If actually the gene has been edited,the nucleotide sequence will get changed.Having to choose such enzyme that cut only one's wide type wild type DNA but not actually gene that is edited,the result will further be compared inorder to confirm whether the gene has been edited or not.
Do you know , human eye and octopus eye are example of convergent evolution ! origin of both are different way but both works the same way, function of both are same !
