A. Only the movement of matter involves living things
Answer:
Sound energy is produced when an object vibrates. The sound vibrations cause waves of pressure that travel through a medium, such as air, water, wood or metal.

Answer:
Option-A
Explanation:
Penicillin is an antibiotic drug that is derived from the fungal species of Penicillium molds especially the<em> Penicillium notatum</em>. The penicillin acts by disrupting the formation of the cell wall and thus prevents the growth of the bacteria.
The discovery of penicillin was accidental when he was studying the petridish of staphylococcus and he found that due to avoidance while the experiment, molds grew in the petridish. The area around the mold was clear and clear rings without the bacteria were easily observed. This lead to the discovery of the penicillin compound.
Thus, Option-A is the correct answer.
<span> (3) contain structures that perform life functions</span>. Although unicellular organisms have less capacity to survive than multicellular organisms, they contain internal structures or organelles that perform different functions to maintain stability and survival.
i. In bright sunlight, the Calvin cycle takes place in the stroma. At the time of the Calvin cycle, the products of the light-dependent reactants, that is, ATP and NADPH are used to transform molecules of carbon dioxide into high-energy sugars.
ii. In the darkness, the Calvin cycle also takes place in the stroma. During the Calvin cycle, the products of the light-dependent reactions, that is, ATP and NADPH are used to transform the molecules of carbon dioxide into high-energy sugars.
iii. If the plant has been kept in dark for an extended period of time, then there may be not enough production of ATP and NADPH taking place in order to continue the Calvin cycle.
