Photosynthesis is the process by which green plants, algae, and some bacteria convert light energy into chemical energy, producing glucose and oxygen from carbon dioxide and water. This process occurs in chloroplasts and is essential for producing food and oxygen, making it foundational to life on Earth.
Mitosis is the process of cell division that results in two identical daughter cells, each with the same number of chromosomes as the parent cell. It consists of several phases: prophase, metaphase, anaphase, and telophase. Mitosis is crucial for growth, development, and tissue repair in multicellular organisms.
Natural selection is a mechanism of evolution described by Charles Darwin. It explains how species adapt over time. For example, in a population of moths, those with coloration that better camouflages them from predators are more likely to survive and reproduce, passing on their traits to future generations. This leads to a gradual change in […]
Cellular respiration is the process by which cells convert glucose and oxygen into energy (ATP), carbon dioxide, and water. It occurs in three main stages: glycolysis, the Krebs cycle, and the electron transport chain. This process is essential for producing the energy that cells need for various functions, from muscle contraction to nerve impulse transmission.
A site engineer oversees day-to-day construction activities, ensures work is carried out according to plans and specifications, coordinates with subcontractors and suppliers, maintains quality control, and resolves technical issues that arise during construction.

Value engineering is a systematic approach to improving a project’s value by optimizing its function, quality, and cost. It involves identifying and eliminating unnecessary costs without compromising the project’s performance, reliability, or maintainability.
Float (or total float) is the amount of time that an activity can be delayed without affecting the project’s completion date. Slack (or free slack) is the amount of time that an activity can be delayed without delaying the start of any immediately following activities.
A work breakdown structure (WBS) is a hierarchical decomposition of a project into manageable tasks or work packages, organized by phases or deliverables. It helps in project planning, resource allocation, and progress tracking.
The critical path is the longest sequence of activities in a project schedule, which determines the shortest possible duration for completing the project. Any delay in the critical path activities directly impacts the project’s completion time.
The main components of a safety program include hazard identification and assessment, safety training and education, personal protective equipment, safety inspections and audits, incident reporting and investigation, and emergency response planning.
