DNA short form for deoxyribonuclic acid is a molecules a group of atoms stuck together in the shape of dobble helix. Its the genitic code that Determines all the characterstics that forms living organisms. we are made of 3 billion cell that we can't see, and each cell has a spcefic job. some banch of cells make up our bone some make our brain some make our skin and all together makes our body. DNA tells every cell what to do. DNA is like a blueprint for our body.

What is amino acid?

The amino acid is an needed chemical inside our body and its often referred to basic bulding block of life. they come in 20 different shapes an kinds of chemicals it stays coiled up inside the nucles which is inside cytoplasm and which is inside the cell.

When blinking hapence you are actully mosturing your eye, eye ball , there is also a layer to protect you from dust so this too. So when you don't blink your eye dust mostureise so your eye , eye ball and the layer will get try. Also when you blink it blocks dust too so when you don't blink dust can pass through which cause eye itches. Also when your eye vanes will break after few hours so when it hapence you eye will start getting red in colour and start burring and itching then if you still hold it like that for some more time then that layer of your eye will break and also if you still keep it for days your brain will forget how to blink so it is better to blink when needed

Elephants belong to the elephantipae family and to the probosicided order. That includes sea cows, elephant and Hyrxes. Elephants can grow up to 13 feet tall and can weigh up to 13,000 pounds. early elephants were very different in there sizes apperance back then compared to what we see of them today. It started with a species known as ''moeitherium'' and were heavily about 3 feet tall . They didn't have trunks like mordern day elephants. Had abroud , flexible upper lip like a tapits for grasping aquatic vegetations. Then came the byatheriume the most important feature that was changed from would be the small tusks That were on the upper and lower jaw. This was changed because the need to be able to have the shearing action to crop plants. Then about 26 millone years ago came the ''numidotherium'' with much slender body shape and not much changed un…

1. Cells: The Building Blocks

The cell is the basic structural and functional unit of all living organisms. If your body were a house, a cell would be a single brick—but a "smart" brick that can breathe, eat, and reproduce.

• Key Characteristics: Every cell contains genetic material (DNA) and organelles (like the mitochondria, which produce energy).

• Specialization: Not all cells look the same. A neuron (nerve cell) is long and wiry to send signals, while a red blood cell is shaped like a disc to carry oxygen.

2. Tissues: The Power of Groups

When a group of similar cells work together to perform a specific job, they form a tissue. In the human body, there are four primary types of tissue:

Definition of Metals

Metals are substances that are usually hard, shiny, strong, and good conductors of heat and electricity.

Main Details

Metals are found in the Earth’s crust.

They are mostly solid at room temperature (except mercury).

They can be:

• How do they eat

microbes don`t have mouths

• Producers: some (like algae) act like plants and uses sunlight to make food

  
  

• Hunters: some (like amoebas) wrap their bodies around microbes and swallow them

Factors of Production

Factors of production are the resources used to produce goods and services.

Types of Factors:

• Land

  • Natural resources used in production

  • Examples: raw materials, fish, physical land

1. Metals: The Conductors

Metals like aluminum, copper, and iron are used because of their unique atomic bonding (the "sea of electrons").

• Properties:

  • Malleability: They can be hammered into thin sheets (like aluminum foil).

  • Ductility: They can be pulled into wires (like copper wiring).

  • Conductivity: They are excellent at moving heat and electricity.

Everyday Metals & Their Properties

1. Iron (Fe)

Where we use it: gates, bridges, tools, cooking pansProperties:

• Strong and hard

• Magnetic (gets attracted to magnets)

• Can rust when exposed to air and water
