Answer:
The total of O2 + CO2 is not a mathematical expression that can be added together.
O2 and CO2 represent different chemical compounds: O2 refers to oxygen gas (two oxygen atoms bonded together), and CO2 refers to carbon dioxide (one carbon atom bonded to two oxygen atoms).
In chemistry, we do not add or combine the formulas of different compounds in the same way we add numbers. Instead, we use chemical reactions and equations to understand how elements and compounds interact and form new substances.
B hydrogen
C oxygen
D nitrogen
The correct answer is option B, hydrogen.
The majority of the atmospheric gases are found in the sea water solution. In supplementation to oxygen and nitrogen, the most profusely found gas in the atmosphere, that is, carbon dioxide is found in the ample concentrations in the ocean waters.
However, hydrogen is not present, and if found it is found in minute concentration. Of the gases, nitrogen is the most abundant gas found in seawater, while oxygen is the second most abundant, and carbon dioxide is the most soluble gas, and one of the various constituents, which influences the pH balance of the ocean.
The answer is B. hydrogen.
Answer:
The correct answer will be option-D
Explanation:
The cell cycle is the cyclically ordered sequence of events taking place in the cells associated with the division of the cell.
The cell cycle takes place in two phases: the interphase proceeded by M-Phase. The interphase of the cell cycle proceeds in G₁, S and G₂ phase. During the G₁ phase, the cell prepares itself to prepare for the next important phase marked by the synthesis or replication of the genetic component of the cell.
The changes that take place during the G₁ phase thus includes the increase in size and the production of ATP as DNA replication is an energy-dependent process.
Thus, Option-D is the correct answer.

a. rift
The Triassic Period indicated the commencement of significant developments that were to take place everywhere in the Mesozoic Era, individually in the administration of regions, the development of life, and the geographic concentration of living things.
At the conclusion of the Triassic, the supercontinent of Pangea, which consolidated all of the modern regions into a single landmass, started to split (rift) apart. As North America segregated from Africa and the Atlantic Ocean started to form, volcanic activity on a comprehensive scale originated carbon dioxide into the environment. This led to global warming and modifications to the oceans that were comparable to those that happened at the end-Permian extirpation.
