the answer is actually A. chemical weathering by oxidation .
chemical weathering works on rocks that contain iron. These rocks turn to rust in a process called oxidation. Rust is a compound created by the interaction of oxygen and iron in the presence of water.
Oxygen and hydrogen make up water
Answer:
Answer is B. Escherichia Coli.
Explanation:
Transformation involves the introduction of foreign DNA into competent organism, I.e E.coli.
This effect can be done through the application of electric current across the cell. This process is known as electroporation.
Answer:
Adhesion and surface tension
Explanation:
Capillary action is the tendency of a liquid to rise or fall in a narrow tube. Two main terms are required to explain capillary action; adhesion and cohesion.
Cohesion is the force of attraction between molecules of the same kind while adhesion is the force of attraction between molecules of different kinds.
Forces of adhesion causes water to move up in a capillary tube. The water is held as it rises by surface tension forces acting on the circumference of the meniscus. The water keeps rising in the tube until the weight of the water drawn up in the tube balances the surface tension acting at the top column of the water.
Answer:
D. a higher number of double bonds between carbon atoms in their structures.
