seals and sea lions are different in what way
seals have ear flaps and sea lions lack ear flaps
no difference
seals lack ear flaps and sea lions have ear flaps
seals can rotate their hind flippers underneath them and sea lions cannot
seals can jump and sea lions cannot
What is the mammalian diving reflex
at the surface, mammals have a high plus rate and metabolism at full speed. when they dive their pulse rate slows down and blood flow diverts from the muscles to sensitive organs like heart and brain
at the surface where the pressure is low marine mammals consume less oxygen and when they dive they consume more oxygen
at the surface mammals have a high plus rate but low oxygen consumption, when they dive the plus rate remains high but they consume less oxygen
what is Cohesion which is property of water because of hydrogen bond
the action or fact of forming a united whole
the state of sticking together
Because hydrogen bonds attract water molecules to each other water molecules tend to stick together this is called cohesion
Cohesion is a term in linguistics that refers to how the structure or the content or text is linked together to create meaning

because that is how they grow
Because Zooxanthellate leave the corals

How does the water Molecule have polarity
Hydrogen end of the molecule gives a positive charge and the oxygen end of the molecule gives a negative charge
hydrogen gives a negative charge to the water molecule and oxygen gives a net negative charge
hydrogen end of the molecule gives a positive charge and the oxygen end of the molecule gives a positive charge
