Prokaryotic
-no nucleus
-unicellular
-does not contain cell organelles like the mitochondria
-smaller and less complex then eukaryotes
-domains Archaea and Bacteria
-DNA is not in a nucleus
Eukaryotic
-nucleus
-can be multicellular
-larger and more complex than prokaryotes
-does contain cell organelles like the mitochondria
-domain Eukarya
-DNA contained in nucleus
Answer:The only difference between a molecule of a compound and a molecule of an element is that in a molecule of an element, all the atoms are the same. For example, in a molecule of water (a compound), there is one oxygen atom and two hydrogen atoms. But in a molecule of oxygen (an element), both of the atoms are oxygen.
Explanation:hope this helps
The natural blind spot is due to lack of receptors where the optic nerve and blood vessels leave the eye. There can also be artificial blind spots when something blocks light from reaching the photoreceptors, or when there is local adaptation of the retina as just after seeing a bright light
I'd like to say it's food. However I'm not sure
Answer:
D. physiological mechanisms are the basis of behaviors.
Explanation:
The example of the development of electric fields as part of the communication between some fish, shows the interrelation that exists between physiology and behavior. This physiological factor that fish have has an impact on their behavior. However, it is necessary to recognize that physiology does not act by itself, but needs to receive a stimulus from the surrounding environment.
This way of communicating is called electrocommunication, a fish generates through its physiology an electric field and a second individual receives that electric field with its electroreceptors.
