Answer:

The correct answer is the third statement.

Explanation:

Alexander Fleming was a Scottish biologist, pharmacologist, and botanist. He discovered Penicillin by accident in 1928. While performing research for determining the characteristics of staphylococci, he stacked all the research jars containing staphylococci in the corner of his lab and went to enjoy the holiday with his family.

After coming back, he witnessed that some of the jars had fungus surrounding them and the majority of staphylococci got eradicated. This marked the discovery of penicillin. It was a novel kind of medicine, which exhibited a tendency to treat infections. Thus, it can be concluded that he discovered a novel kind of medicine, which could treat infections.

Which of the following abiotic factors might have an effect on how much photosynthesis can occur by the producers in an ecosyste

Evgesh-ka [11]

Abiotic factors such as temperature, water quality, air quality, soil quality, and sunlight efficiency affect the rate of photosynthesis. Thus, the correct option is D, i.e. All of the above can affect photosynthesis.

<h3>What is Photosynthesis?</h3>

Photosynthesis may be defined as a process through which green plants synthesized their own food (glucose) via carbon dioxide and water in the presence of sunlight.

The rate of photosynthesis primarily depends on the numerous abiotic factors which are present in a particular environment.

For example, Desert plants accomplish photosynthesis by the CAM pathway, which requires less water as compared to rainforest plants.

The maximum rate of photosynthesis occurs in the region of photosynthetically active radiation (PAR), which belongs to the wavelength of 400nm-700nm.

Therefore, it is well described above.

How does substance A affect the amount of activstion energy needed by the process? Explain?

asambeis [7]

<u>Answer</u>:

Substance A affects the amount of the activation energy needed by the process by catalyzing the reaction. Enzymes are the natural biological catalyst that lowers the activation energy for a reaction to proceed faster at a low energy requirement.

<u>Explanation</u>:

The reactants in the solution react to form a product. For a reaction to happen some energy is needed. The energy which helps reactants to break some bonds and make other bonds to make a product is known as activation energy.

Enzymes are the biological molecules which lower this activation energy by catalyzing the reaction by helping in breaking old bonds and forming new bonds to create a product.

Sloan [31]

CAM plants keep stomata closed in the daytime, thus reducing loss of water. They can do this because they - fix $CO{2}$ into organic acids during the night.

The correct option is a.

As an adaptation to dry environments, certain plants developed a carbon fixation mechanism known as crassulacean acid metabolism, or CAM photosynthesis, which enables a plant to photosynthesize during the day but only exchange gases at night.

During the day, the malate is transferred to chloroplasts where it is transformed back to $CO2$ , which is then utilised during photosynthesis. At night, the $CO2$ is stored as the four-carbon acid malic acid in vacuoles. The enzyme RuBisCO is surrounded by a concentration of pre-collected $CO2$ , which improves photosynthetic efficiency. Plants in the Crassulaceae family were the ones that initially revealed this process of acid metabolism.
