Q.6A) Radiation heat transfer is the transfer of thermal energy from a body in the form of electromagnetic waves (mainly infrared radiation).
It does not require any medium, so it can occur even in a vacuum.
Example: Heat reaching Earth from the Sun.
Difference from Conduction and Convection
| Mode | Medium Required? | How Heat Transfers |
|---|---|---|
| Conduction | Yes (solid) | By direct molecular contact |
| Convection | Yes (fluid – liquid/gas) | By actual movement of fluid particles |
| Radiation | No medium required |
Fundamentals of Ethics
Ethics – Meaning
Ethics refers to a set of moral principles and values that guide the behavior of individuals and professionals. In engineering, ethics ensures honesty, responsibility, safety, and accountability in all technical and professional activities.
Personal vs Professional Ethics
:Personal ethics are moral values shaped by culture, family, and belief systems. They include honesty, kindness, and integrity.
:Professional ethics are rules and standards defined by the

1. Social Groups: Meaning, Characteristics, and Classification -
Meaning of Social Groups
A social group is a set of individuals who interact regularly, share a sense of identity,
and are bound by common norms, values, or goals. Unlike mere aggregates (like
people waiting at a bus stop), a social group provides structure, stability, and
predictability to interactions. Members perceive themselves as part of a distinct
entity and develop a sense of belonging and loyalty.
Example: Family, student clubs,...

1. FUNDAMENTALS OF ETHICS
Meaning of Ethics
Ethics is the systematic study of moral values, principles, duties, and standards that guide human behavior. In engineering, ethics provides a framework for decision-making, ensuring that engineers act with honesty, integrity, fairness, and responsibility toward society, the environment, and stakeholders.
Characteristics of Ethical Behaviour
1.Universality – Ethical principles apply broadly to all situations and people.
2.Impartiality – Decisions
...## Overview of the Cell Cycle -The cell cycle is an ordered sequence of events enabling a cell to grow, replicate its DNA, and divide into two genetically identical daughter cells, ensuring accurate genetic transmission. It comprises interphase (G1, S, G2 phases) and the mitotic (M) phase (mitosis and cytokinesis). During G1 phase, the cell grows metabolically, synthesizing proteins and organelles while assessing environmental conditions at the restriction point before committing to division. S
Here is the information on the structure and function of the cell components you asked about, including chemical components of cells, catalysis, and energy use:
Lysosome: Lysosomes are membrane-bound, dense granular organelles containing about 50 hydrolytic enzymes active in acidic pH. They digest intracellular and extracellular materials by breaking down macromolecules, waste materials, and cellular debris. Structurally, lysosomes have an outer limiting membrane and an inner matrix with enzymes
