Answer: "antibodies" . (specifically, "antibodies from plasma cells" .).

The resting potential of the neuron would be reduced from
-70mV. This is because increasing K+ ions inside the cell reduced the electro
negativity of the inside of the cell in comparison to the outside. Therefore,
the reaching the potential to induce an impulse would be easier but then the
impulse would be weaker than normal.
Answer: Amazon are the largest rainforests in the world.
Explanation:
The Amazon Rainforests are located in the northern South America. The following are the ways in which the Amazon rainforests are important to the world.
1. The Amazon Rainforests can regulate the major cycles like water cycle, carbon cycle and oxygen cycle necessary for maintaining the aesthetic qualities of the environment. These are also necessary for maintaining the weather patterns. These phenomena makes the earth habitable.
2. These forests provides accommodation to 30 million native people. These forests are also the source of 10% if the total world's biodiversity.
Ecosystems have trouble adjusting to short-term changes - This is false.
Eco system changes can be long term and short term. Few short-term environmental changes that can change an eco system are - drought, smog, volcanic eruptions, floods etc. An ecosystem can easily adapt to short-term changes. For example, after a forest fire plants can re-grow from their roots. Many species have features to help them cope with natural, short-term environmental changes.
