Hello!
The statement that <span>best explains whether the mass is conserved or not during photosynthesis is that </span><span>It is conserved because the total number of O atoms on each side is 18.
This comes from the Law of Conservation of Mass. It was discovered by Antoine Lavoisier, who is often called "the father of Chemistry". It states that matter is neither created nor destroyed in chemical reactions and that it only changes. In Photosynthesis, the chemical reactions transform the Oxygen in carbon dioxide and water to sugars and molecular oxygen.
Have a nice day!</span>
Answer:
A. nucleus
Explanation:
The cell nucleus is a structure present in eukaryotic cells, being, precisely, the main characteristic that differentiates them from prokaryotic cells, those that have the nucleoid genetic material. It is in the nucleus that this is the instructions for cells to differentiate and different types of tissues.
To facilitate understanding, an analogy is possible. Let's say the cells are industries, each department within the company is responsible for performing a specific function. In this case, these departments would be organelles, such as the Golgi complex, mitochondria, among others. The core, in this comparison, would be the management or administration sector. This is because it is exactly in the nuclear region that the genetic information that coordinates and commands cellular functions is present.
<span>Surfactant, which is a mixture of fatty lipids and proteins are secreted by alveolar type II cells that line the perimeter of the inside of our empty alveolar space and aids in the movement of air and liquids that go in and out of the lungs. These cells may line other vital organs to protect it against outside wear and tear and keep the tissue inside our bodies intact making bodily functions working more smoothly.</span>
