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.
Can't see the chart. But chloroplasts, cell wall, central vacuole are only in plant cells
The phylogenetic tree is commonly used by biologists to study evolutionary relationships between organisms and their ancestors. To add up, it is a diagram that branches the "phylogeny" of a single organism which could be very significant and determining on how genetically different or similar they are to their ancestors.
Answer: Point source
Explanation:
An exotoxin is a toxic substance secreted by bacteria. The botulism exotoxin is the exotoxin secretes by bacterial strain named as Clostridium botulinum.
Point source outbreak is a condition in which people are exposed to the same source of infection from a pathogen. This may occur due to the consumption of a single meal which is being infected by the pathogen. This may lead to incidences of food poisoning, disease and even mass death.
