Answer: Option B) . a decrease in the amount of oxygen dissolved in
the pond
Explanation:
Anaerobic bacteria are able to survive in the absence of oxygen while aerobic bacteria survive only in the presence of abundant oxygen.
Hence, while reduced levels of dissolved oxygen in the pond decrease the amount of aerobic bacteria like Bacillus; anaerobic bacteria like Actinomyces flourish since they survive on organic substances like methane, cellulose instead.

Answer:
The main purpose of light dependent reactions of photosynthesis is to generate ATP and NADPH.
Explanation:
Photosynthesis consist of two reactions 1 light reaction 2 dark reaction .The light reaction occur in the thylaKoid of Grana to produce Adenosine tri phosphate (ATP) and NADPH
Role of ATP
ATP is an energy rich molecule which undergo hydrolysis to provide energy for Carbon di oxide fixation during dark reaction. The carbon di oxide fixation is very much important to produce glucose.
Role of NADPH
NADPH act as reducing equivalent that carry out the reduction of phosphoglyceric acid formed in the first step of light independent reaction to generate phosphoglyceraldehyde(PGALD). Some PGALD then undergo various enzymatic reaction to form glucose and rest are utilized to regenerate ribulose bis phosphate(RUBP).
Answer: system development life cycle
Explanation: system development life cycle is a term used in systems engineering, information systems and software engineering to describe a process for planning, creating, testing, and deploying an information system.
