Answer:
have the same number of electron energy levels
Explanation:
All of the elements in the same period have the same number of atomic orbitals that are occupied by electrons that are in constant motion. For example the elements in the first period have one orbital for its electrons. The elements in the second period have two orbitals for their electrons. As you move down the table, every row adds an orbital. At this time, there is a maximum of seven electron orbitals.
Answer: your answer is below
Photosynthesis is important to living organisms because it is the number one source of oxygen in the atmosphere. Without photosynthesis, the carbon cycle could not occur, oxygen-requiring life would not survive and plants would die. The importance of photosynthesis in our life is the oxygen it produces.

i hope it helps if not pls let me know
Answer:
Chlorophyll absorbs the light needed for photosynthesis.
Explanation:
Photosynthesis is the process where green plants manufacture their food. During photosynthesis, carbon dioxide combines with water in the presence of light energy from the sun to produce glucose and oxygen as a byproduct.
From the statements listed, chlorophyll does not combine with water. Chlorophyll is a pigment in plant that simply absorbs light energy from the sun which is necessary for the process of photosynthesis. This makes photosynthesis a simple process in which light energy from the sun is transformed to chemical energy.
Answer:
Different mass
Different volume
Same density
Explanation:
Intensive physical properties are those properties of a substance that is not dependent on amount i.e. do not change in response to changes in the amount of the substance. Intensive properties include density, temperature, boiling point etc.
On the other hand, extensive properties are those properties that are dependent on the amount of the substance. For example, mass and volume are extensive properties.
Hence, according to this question, measuring an entire bar of soap and comparing it to a piece of soap, the bar and the piece would have a:
- Different mass ( size dependent)
- Different volume (size dependent)
- Same density (size independent)
The air as there are many elements in the air
