The human body system

The human body system. Cell, Tissue, Muscle, Organ, System, Body.

The cell is made from different parts of the body organ.

Each part has many roles in a single human system, I know what you think what I am talking about, 
well, it's start off with the (muscle cell) as you see in the image.

Muscle Cell is found in our Muscle Tissue, the Muscle Tissue is soft but that can compose muscles in animal bodies, that gives a rise to the muscles and ability to contract within the cell.

The average heart is the size of a fist in an adult but you're Heart can beat at 115,000 times each day. And it pumps over 115,000 blood times each day,
and our heart has an Electrical System Controls the rhythm every time it beats the heart.

There are 11 major that works together Organ Systems,
on Google search, I find some things to help to make it easy for you.😊

but you can search them up so you can learn for your self and express what it means to your self.
And to be honest I'm too lazy but you can find some interesting facts about the system and cell and the others.

Forms of energy

there are different many types of energy form. there's 6 inti 

• Potential Energy is any type of stored energy. It can be chemical, nuclear, gravitational, or mechanical.
• Kinetic Energy is found in the movement
• gravitation 
• chemical 
• nuclear 
• Els
• motion
• THERMAL ENERGY AND TEMPERATURE. 

and there are many more:

Light energy, Heat energy, Mechanical energy, Gravitational energy, Electrical energy, Sound energy, Chemical energy, Nuclear or Atomic energy and so on to Kinetic energy.
And each of one of has a role to play in.

Osmosis

Explain the osmosis process in plant roots.

Plants rely on the nutrients and water in the soil to survive, to tack plans the chan line.

And the basic Function of xylem is to transport water from roots to shoots and leaves.

They are mostly found on the Under-surface of plant leaves, And

(Also stoma-plural Stomata) is a tiny opening or pore that is used for gas exchange.

States of Matter

1. (Solid) = well it means to (i.e or e.g), Definite volume and definite shape.

And the same goes for gas...

2. (Liquid) = conforms to the shape can nearly  (the others being solid, gas, and plasma), And also can do with the state with a definite volume, but no fixed shape...

3. (Gas) = gases are made up of just one atom, but they made up of two or more of the same atoms joined together, contain in different atoms...
