Answer:
The correct option is C. The level of organization best represented by the corn plant is : organism, the level of organization directly above organ system organ system
Explanation:
An organism can be described as a living thing made up of organ systems.
Plants are organisms that have levels of organizations similar to animals. Cells in plants make up tissues. There are mainly two types of tissues in plants: the meristematic tissue and non-meristematic tissue.
Just like animals, plants have organ systems. There are two kinds of organ systems mainly in plants: the shoot system and the root system. Hence, option C is the correct option.
Answer:
Carbon and Oxygen cannot react to form an ionic compound because the two elements are non-metals. To form an ionic bond, a metal combines with a non-metal through electrostatic attraction of oppositely charged ions.
An organic compound<span> is any member of a large class of gaseous, liquid, or solid chemical </span>compounds whose molecules contain carbon and <span>a hydrocarbon is compound of hydrogen and carbon, such as any of those that are the chief components of petroleum and natural gas.</span>
When changing states, only the intermolecular forces are considered, which, in water's case are hydrogen bonds. In order to go from solid to liquid to gas, the hydrogen bonds between the water molecules must be weakened to a certain degree that allows the molecules to spread further apart in liquids, and must be broken altogether to separate the molecules in order to turn it into gas.
Therefore, the answer is d.
The reason it is not the covalent bonds within molecules (despite the fact that it will turn water into a gas, it’s not water vapour, but hydrogen and oxygen gas) is that when bonds within a molecule are broken, this is called decomposition and it is a CHEMICAL change. Changing states is only a PHYSICAL change.
It is not ionic because water has covalent bonds.
Hydrogen bonds can only occur BETWEEN molecules (intermolecular forces).
Covalent bonds can only occur WITHIN molecules (intramolecular).
