im not understanding the question, but if its a solid then the reactants are precipitate
Answer:
D. Grass
Explanation:
Every living organism must contain one or more cells to be considered "living". Each cell, however, contains certain structures that perform specific roles called ORGANELLES. These organelles are of different types and hence, perform different tasks. For example, mitochondria is the power house of a cell i.e. site of energy production, and hence, is found in every eukaryotic cell.
On the other hand, chloroplast is an organelle designed to perform photosynthesis, which only occurs in plant cells. Since only plant cells can undergo photosynthesis, only plant cells can contain chloroplast. Hence, according to this question, GRASS as a type of plant is an organism that will contain both mitochondria and chloroplast in its cells.
Answer:
B) Add appropriate quantities of weak acid and its conjugate base to water.
C) Partially neutralize a weak acid solution by addition of a strong base.
(D) Partially neutralize a weak base solution by addition of a strong acid.
Explanation:
A buffer solution is made by a weak acid and its conjugated base or a weak base and its conjugated acid.
If you add a weak acid to water, you can adjust the pH of the buffer solution by adding a strong base.
If ypu add a weak base to water, you can adjust the pH of the buffer solution by adding a strong acid.
1) it explains about stability of an atom by including stationary state.
2) it explains tge quantization of energy.
3) it gives the concept of angular momentum of a revolving electron.
