Explanation
The stomach is an organ involved in digestion , not waste elimination. The four parts of body play important role in eliminating waste material from our body Lungs : remove carbon dioxide through exhalation Kidneys : filter waste and excess substances from the blood, producing urine Skin : removes waste through sweating Liver : detoxifies harmful substances and aids in their removal

Explanation
Telescope : It is a device used to see distant objects. The word telescope was coined in 1611 b y the Greek mathematician Giovanni Demisiani  ** ND22-1-2023

Explanation
The breakdown of CFCs releases chlorin e, which then acts as a catalyst for the destruction of the ozone layer. ** ND22-1-2023

Explanation
The form of cell division known as mitosis is responsible for the body's expansion and repair. while Gametes are created as a result of the cell division process known as meiosis . ** ND22-1-2023

Explanation
The Milky Way is the galaxy that contains our solar system It consists of  100–400 billion   stars The Milky Way is a huge collection of:  stars dust gas It is visible as a hazy band of white light Additional Information The nearest galaxy to our Milky Way is  Andromeda Largest galaxy in the Universe is  a Spiral galaxy 

Explanation
Inclined planes are used to move heavy loads over vertical obstacles. The inclined plane is one of the six classical simple machines defined by Renaissance scientists.  ND20-1-2023

Explanation
The Earth's Moon has considerably less mass than the Earth itself. Not only is the Moon smaller than the Earth, but it is only about 60 percent as dense as Earth. Thus, the gravitational attraction on the Moon is much less than it is here on Earth , and a person weighs less on the Moon. ND20-1-2023

Explanation
The physical weight of our body is determined by the pull of gravity on it ND20-1-2023

Explanation
When two surfaces slide over one another the tiny bumps push on each other.
Friction causes a force on a surface  that is in the opposite direction to its motion.
Friction can be reduced by the application of lubricants

Explanation
Chromatography is one of the latest techniques , which is used to separate the colored components of a mixture . Ink is a mixture of several dyes therefore we can separate those colors from one another using chromatography . **** ND20-1-2023

Explanation
The smallest particle of a compound is called a molecule . Molecules are formed when atoms of the same or different element s combine.  while The matter is made up of the smallest particles called atoms *** ND20.1.2023

Explanation
In a solid state, particles cannot move from their position. They can only vibrate at their mean position .  The particles in solids vibrate about fixed positions; even at very low temperatures. *** ND18-1-2023

Explanation
The nucleus is primarily composed of protons and neutrons, collectively called nucleons . protons and neutrons,  both types of particles reside inside the nucleus of an atom *** ND18-1-2023

Explanation
 non-magnetic materials are examples Rubber plastic stainless steel feather paper mica gold Silver leather *** ND18-1-2023

Explanation
The force of friction opposes the motion of an object, causing moving objects to lose energy and slow down. *** ND18-1-2023

Explanation
When the parachute opens, the air resistance increases. The skydiver slows down until a new, lower terminal velocity is reached. *** ND18-1-2023

Explanation
Producers, also known as autotrophs. They are organisms that can produce their own food through photosynthesis, using water (H2O), carbon dioxide (CO2), and sunlight to produce glucose and oxygen.

Explanation
The correct answer is: Gases have definite volume Gases: Have indefinite shape Have indefinite volume Can be compressed

Explanation
If an opaque object is moved closer to the light source, the shadow gets bigger. This is because the light source appears larger and more intense from a closer distance, casting a larger shadow.
