Answer:
Ocean currents bring nutrient-rich water into coastal regions.
Explanation:
About 70 percent of our planet is covered by water. The earth has been declared a "blue planet" because it looks blue from space. About 96 percent of this water is the sea or salt water, made up of the ocean that covers the Earth.
Within these oceans, there are many different types of habitats or environments inhabited by plants and animals, from the freezing of polar ice to tropical coral reefs. Most marine life is found in coastal habitats.
The correct options are, frying an egg and burning candle.
Explanation :
Physical change : It is a change in which no new compounds are formed only changes occurs in size or state of substance. In this, there is no changes in the substance or compound.
Chemical change : It is a change in which a new compounds are formed by the chemical reaction. Changes occurs in their chemical composition and properties.
Frying an egg : It is a chemical change because a new substance is form by heating.
Burning a candle : It is chemical change because new substances are formed (carbon dioxide, water and heat) by burning.
Boiling alcohol : It is physical change because only changes in the state.
Melting and ice : It is a physical change because only changes in the state.
Making coffee : It is a physical change because no new substance is formed.
Therefore, frying an egg and burning candle are the example of chemical change.

Answer:
The internal structures disrupted by this chemical are probably VACUOLES.
Explanation:
A vacuole is a large membrane-bound vesicle in a cell's cytoplasm.
The central vacuole of a cell houses the digestive processes which includes chemicals that come to attack the cell; also it helps the cell regulates it's water concentration during changing environmental conditions.
vacuoles are present in the absorptive cells (enterocytes) covering the wall of the intestine
