In addition to carbon dioxide, what other two ingredients does a plant need for photosynthesis? ( A: water and sunlight B: Sunlight and soil C: sunlight and oxygen D: water and oxygen)
In addition to carbon dioxide, water and sunlight are the two ingredients that a plant need for photosynthesis. Therefore, the correct option is option A.
What is photosynthesis?Green plants along with certain other organisms convert sunlight into chemical energy through a process called photosynthesis. Light energy is gathered and utilised during photosynthesis by green plants to change moisture, carbon dioxide, plus minerals into oxygen- and energy-rich organic molecules.
It is impossible to overstate the role that photosynthesis plays in sustaining life on Earth. There'd soon be food or even other organic materials on Earth if photosynthesis stopped. The majority of life would vanish, and eventually, the atmosphere of Earth would contain almost no gaseous oxygen. In addition to carbon dioxide, water and sunlight are the two ingredients that a plant need for photosynthesis.
Therefore, the correct option is option A.

Describe the concentration of hydronium ions and hydroxide ions when a base is added slowly to a white vinegar solution. The pH of white vinegar is 3.1.
Answer: as you add the base it added some PH. The Ph lever of white vinegar is2.4 - 3.4
The concentration of hydronium ion will decrease, and hydroxide ion will increase when a base is added to a white vinegar.
What is pH?pH is the measure scale of how acidic and basic the solution is.
The acid has low pH value and a base has high pH.
When a solution is basic, more hydroxide ion are present and when a solution is acidic, more hydronium ion are present.
Neutral solution will have equal amount of H+ ion and OH- ions.
A buffer neutralizes the pH of any solution.
Thus, the concentration of hydroxide ion will increase and the concentration of hydronium ion will decrease when a base is added to a white vinegar.
