New oceanic lithosphere is unable to form at mid ocean ridges. This is False. New oceanic lithosphere is able to form at mid-ocean ridges. This is where the New oceanic lithosphere is usually formed
I found the attached image on the internet and it really helps complete this exercise.
First question:
In the presence of an enzyme, the course of the reaction is shown by the
red curve. The necessary energy to make a reaction occur is less when there is an enzyme to help the reaction happen. Enzymes work as catalysts that act over substrates converting them into different molecules in a much accelerated way then it would happen without the enzyme's help, if it would happen at all.
Second question:
The activation energy is represented by
line B. The activation energy is the energy needed to be available for a reaction to happen. If we compare it with line A, which represents the activation energy necessary for a reaction without an enzyme, we can see how much less energy is necessary to dispend when an enzyme is part of the reaction. Line C represents the energy resultant from the reaction.
So you don’t tear any tissue and so they get more elastic.
Microtubules provide a rigid structure, or cytoskeleton
Brown algae and dinoflagellates
Reason: Because they are the closest being in the same branch, makes them the most related.
Hope this helps! :))
