Answer:
See the answer below
Explanation:
The amount of light available to Chlorella culture might affect the growth dynamics of the alga <u>because the light is an important factor necessary for the synthesis of carbohydrates and other important molecules in the body of the organism.</u>
The process of synthesizing carbohydrates is termed photosynthesis and during this process, the energy of light is used to excite the photosystem of the chlorophyll of the organism, leading to the release of electrons whose energy is used to synthesize an energy molecule that is utilized in the latter part of the photosynthetic process. The entire process of photosynthesis can be summarised as an equation below:

<em>The manufactured carbohydrates act as food for the organism and are broken down during respiration to release energy necessary to drive metabolic processes that bring about growth and development.</em>
Hence, the amount of light is an important factor that might affect the growth dynamics of all green plants, including the Chlorella.
Shawna's work on her blog about cars would be best described as
unreliable. Although speaking outside of a scientific context, she is
very knowledgable about cars, it is also important to consider that all
of her information comes either from second-hand sources, or from
opinions that she personally holds, which is not the basis for reliable
information.

Answer:
D. physical weathering
Explanation:
The geological process that initiates and leads to the breaking of the rocks is termed as the physical weathering. In this process, the chemical composition of the rocks do not undergo any change. The process of breaking of the rocks is both gradual and sudden. The movement of the earth, the change in the temperature, the rise and fall of the water level, the presence of ice rocks for longer duration of the time, and the melting of the snow are some of the reasons which causes the physical weathering.
The phenomena in the given expert represents the physical weathering.
Answer:
the second one is the correct one
