Metallurgical Optical Microscope
A metallurgical optical microscope, also known as a metallographic microscope, is a specialized type of optical microscope designed for the examination and analysis of opaque materials, such as metals, ceramics, and polymers. It is a valuable tool in materials science, metallurgy, and other fields where the microstructure of materials needs to be studied. Working Principle: The working principle of a metallurgical optical microscope is based on the reflection and...
Although all three species—the brown bear (mammal), Chinook salmon (bony fish), and European honey bee (insect)—carry out the same essential life process of gas exchange to support cellular respiration, the structural adaptations they exhibit reflecta remarkable diversity in response to this shared biological demand, shaped by their differing environments, metabolic needs, and body plans. Mammals such as the brown bear have evolved an internal lung system supported by a double circulatory system,

Q1:What is meaning of education
The word ‘Education’ has been derived from two Latin words. Educare and Educere.’
Word “Educare” means to “bring up” or “to raise”. The word “Educere” means to “draw out” or “to lead out”
All these meanings indicate that education seeks to bring up the good qualities in child and draw out the hidden talent in every individual.
Q2: Definition of education
The delivery of knowledge, skills and information from teachers to students
most mammals live on land, meaning they breath in oxygen through the air. they are at risk of desiccation, therefore, their gas exchange system (the lungs), is found deep inside their bodies to avoid any water loss. air has a relatively high oxygen concentration of approximately 21%, and is easy to ventilate.
air enters the lungs through the trachea, which then splits into 2 bronchi, and then separates into smaller bronchioles. the tubes are held together by rings of cartilage. on the bronchiole
Gas exchange is the biological process through which organisms obtain oxygen from their environment and expel carbon dioxide, a waste product of cellular respiration. Oxygen is essential for aerobic respiration, which produces ATP, the energy currency of cells. Without a constant supply of oxygen and efficient removal of CO₂, cells cannot perform metabolic functions, leading to organismal failure. Different animal groups have evolved diverse gas exchange systems, finely

#what is css ? Discuss type of css with example.
CSS (Cascading Style Sheets) is a stylesheet language used to control the look and formatting of HTML elements on a webpage. It separates content (HTML) from presentation (design), allowing for better flexibility and control in web development. CSS is used to define styles such as: *Font size and color *Layout and positioning *Backgrounds and borders *Animations and transitions.
There are three main types of CSS: 1. Inline CSS *Applied directly to
