The answer is nucleic acid. Every nucleic acid is composed by a base, a sugar and a phosphate group. And they can form DNA or RNA by combining together.

Answer;
-Tropical rainforest; tropical seasonal forest
In contrast with the tropical rainforest, the soil of the tropical seasonal forest is more nutrient-rich and this type of biome has fewer insects, parasites, and fungal diseases. therefore, in many places, these areas are highly endangered.
Explanation;
The tropical rainforest is one of the world's most threatened biomes, despite being home to some of the most diverse and unique species on the planet. The tropical rainforest is a biome with a constant temperature and a high rainfall. The level of humidity and density of the vegetation give the ecosystem a unique water and nutrient cycle. Rainforests around the world are threatened by human expansion.
The tropical seasonal forest has more or less densely growing trees which lose their leaves during the dry season. It typically contain a range of tree species: only some of which drop some or all of their leaves during the dry season.
Answer:
addition to the external medium.
Genearlly, potassium is an intracellualr ion, therefore there is higher concentration of potasium ions with its positive charges inside than outside.In addition potassium ion has many leaking potassium channels in the cell membrane,which permit K+ to escape down the gradient to the extracellular medium.
Therefore when KCl is added to the external medium of a resting neuron, the concentration of external K+ increase than intracellular medium, preventing K+ from diffusing out to the external medium, retaining their positive charges, therefore favouring depolarization of the neuron.This decreases the RMP, leading to depolarization.
If the KCl is reduced, less k+ are available outside compare to the inner medium.Therefore electrochemical gradients is sets up for leaking of K+out of the intracellular layers, caring the positive charges along, leaving the inside more negative (together with the negative charges of the anions of the intracellular layer). This is reversal of charges.And it increases the RMP.
