I hope this helps :)
I think the correct answer would be option 1. It is the marine life in the Arctic circle that is most affected by the extinction. It was estimated that about 40% of the endangered animals of this part are in extinction. This is because of climate change and the destruction of their homes. Also, scientists say that the temperature change of this area is increasing rapidly as compared to the rest of the world which means the animals would have to adapt to these conditions and while some can adapt easily, there are those that cannot and would die to extinction.

Answer:
Following statements are correct
A graded potential has a threshold Graded potential amplitudes decay over distances
Graded potentials can summate in space and time
Graded potential amplitude increases with stimulus strength
Explanation:
Graded potential is generated in a neuron when ions enter or exit through the ligand gated channels. In general, this potential decreases with time before reaching axon. Signals that reach the graded potential, determine whether the amplitude of the potential will reach the threshold and hence causes action potential. Graded potential travel only over a short distance and is either depolarization or hyperpolarization. Their strength reduces with time as the charged ions move out of the membrane. They summate temporally or spatially
Graded potentials spread by passive means i.e spreading electronically to neighboring membrane regions.
Hence, the correct statements are
A graded potential has a threshold Graded potential amplitudes decay over distances
Graded potentials can summate in space and time
Graded potential amplitude increases with stimulus strength
