The mass number of an oxygen atom with 8 protons and 8 neutrons is 16. The mass number of an atom is the total number of protons and neutrons in the nucleus. This atom is an isotope of oxygen, called oxygen-16.
The mass number of an oxygen atom that has 8 protons and 8 neutrons in the nucleus is 16.
The mass number of an atom is the total number of protons and neutrons in its nucleus. The number of protons in an atom is also the atomic number, which identifies the element. In the case of oxygen, the atomic number is 8, because there are 8 protons in the nucleus.
Neutrons are subatomic particles that, together with protons, make up the majority of an atom's mass. Neutrons and protons have approximately the same mass, while electrons are much lighter. Therefore, the mass number, which represents the sum of the number of protons and neutrons, provides a good estimate of the mass of an atom.
In this case, the atom is an isotope of oxygen, known as oxygen-16, because it has 8 protons and 8 neutrons. Isotopes are atoms of the same element that have different numbers of neutrons and therefore different mass numbers. Oxygen-16 is the most abundant isotope of oxygen, making up about 99.76% of all oxygen atoms.

B.respiration
C.decomposition
D.building proteins
The correct answer is A.photosynthesis
In the process of photosynthesis plants use the energy of the sunlight and absorbed CO2 from the atmosphere to create simple sugars. In this process, plants also create oxygen molecules that are released to the athmosphere.
Human activities that involve burning fossil fuels cause a release of a huge amount of CO2 to the atmosphere. Photosynthesis in plants can reverse the effects of this, but only to a certain extent. This is, but all means, not enough to stop the global warning effect that the CO2 build-up in the atmosphere is causing.
Answer:The correct answer is -
A.photosynthesis.
Explanation:
Human activities such as burning of fossil fuels (like coal and oil) , clearing of forests can lead to the accumulation of CO2 (carbon dioxide) in the atmosphere, which affects the carbon cycle.
This can lead to many harmful effects like global warming (overall rise in the earth temperature).
These human interactions can be counteracted through photosynthesis.
Photosynthesis is a process of formation of food (glucose) in green plants and algae using CO2 and water in the presence of sunlight.
It releases oxygen in the atmosphere as a byproduct of this process.
The atmospheric CO2 can be reduced through photosynthesis and therefore, it can help counteract the given human activities.
Thus, option A) is the right answer.
-can be solids, liquids, or gases
-have a uniform structure or composition
-are made from the remains of plants and animals
