Answer: map
Explanation: I say its map because a map represents the entire earth
*The key function of each of the two photosystems is to absorb light and convert the energy of the absorbed light into redox energy, which drives electron transport.
In PS II (the first photosystem in the sequence), P680 is oxidized (which in turn oxidizes water), and the PS II primary electron acceptor is reduced (which in turn reduces the electron transport chain between the photosystems).
In PS I, the PS I primary electron acceptor is reduced (which in turn reduces other compounds that ultimately reduce NADP+ to NADPH), and P700 is oxidized (which in turn oxidizes the electron transport chain between the photosystems).
Excitable cells like those found in muscle tissue are expected to be present in higher quantities in arteries than in veins.
<h3>What are Excitable cells?</h3>
Excitable cells are defined as those cells that are capable of generating electrical impulses when stimulated. Example of such cells include:
- muscle cells( smooth, skeletal and cardiac)
The artery is made up of higher amount of smooth muscles than the veins therefore, excitable cells like those found in muscle tissue are expected to be present in higher quantities in arteries than in veins.
