Newton's 3 Laws of Motion
Newton's 1 LawAn object at rest stays at rest, an object in motion stays in motion until it experiences an unbalanced force.
|
Newton's 2 LawThe acceleration of an object depends on the mass of the object and the force applied.
|
Newton's 3 LawFor every action there is an equal and opposite reaction.

Physics
Velocity
Velocity is the speed of something in a given direction.
Acceleration
It is the rate of change of velocity in per unit in a given time
Positive and Negative Acceleration
Positive acceleration is accelerating velocity, while negative acceleration is when the velocity is decreasing.
Centripetal Acceleration
It's a force that makes a body follow a curved path.
Scalar quantity
Scalar Quantity means having no direction.
Vector Quantity
It means having a direction.
Speed (equation)
Speed = Distance/Time or S = d/t
Cloning
Cloning is the process of making a genetically identical individual of another organism. One example is Dolly the sheep. She was the first mammal to be cloned from an adult somatic cell.
Artificial Selection
Artificial Selection is when you take an organism with a certain trait and breed it with another organism with a certain trait.
Genetic Engineering
Genetic Engineering is when you take a gene, alter it, then put it back or put it in an other organism.
Lesson 7: Endocytosis,Exocytosis, Diffusion, and Osmosis
Endocytosis: endocytosis is the process of actively transporting molecules into a cell.
Exocytosis: it is the process of which a cell transports secretory products through the cytoplasm.
Diffusion: it is the physical process where molecules move from a higher concentration to a lower concentration(with concentration gradient)
Osmosis: it is the process where molecule move from a low concentration to a high concentration.
Exocytosis: it is the process of which a cell transports secretory products through the cytoplasm.
Diffusion: it is the physical process where molecules move from a higher concentration to a lower concentration(with concentration gradient)
Osmosis: it is the process where molecule move from a low concentration to a high concentration.
Lesson 6: Cells, Tissue, Organ, Organ System
Cell: it is the smallest structural and functional unit of an organism.
Tissue: a group of cells that have a similar structure.
Organ: a self-contained group of tissues that perform a specific function.
Organ system: an organ system is a group of organ performing the same task.
Tissue: a group of cells that have a similar structure.
Organ: a self-contained group of tissues that perform a specific function.
Organ system: an organ system is a group of organ performing the same task.
Lesson 5: Structure and Function of a cell
Nucleus: it contains most of the genetic material in a cell
Golgi complex: it's major function is packing, sorting and modifying proteins
Chloroplast: it is located in plant cells and its function is to produce food for the plant
Endoplasmic Reticulum: it transports proteins and makes lipids
Ribosome: it makes proteins
Mitochondrion: it is the powerhouse of the cell
Lysosomes: they work like the digestive system and break down unwanted materials and break up larger molecules into smaller ones.
Large central vacuole: it stores materials and wastes

Lesson 4 : Atoms, Molecules, and Compounds
Atoms: The basic unit of an element.
Molecules: molecules are a group of atoms bonded together
Compounds: something made of two or more element
Some important molecules that can be found in cells are:
The function of lipids: they are used for storing energy and making energy from fats.
The function of carbohydrates: they are the source of energy in our body and they store energy(starch and sugar)
The function of proteins: to repair and build the body and to make amino acid
The function of nucleic acid: carries information
Molecules: molecules are a group of atoms bonded together
Compounds: something made of two or more element

The function of nucleic acid: carries information
Elements present in the Human body
Lesson 2 : Cell Theory
The cell theory states that cell are the unit of life, a cell can only be made from another cell, and that all biological organisms are composed of cells. The people responsible for making the Cell Theory are Robert Hooke, Anton Wan Leeuwenhoek, Matthias Schleiden, Theodore Schwann, Rudolf Virchow.
Lesson 1: Cells : )
A cell is the smallest structural and functional unit of an organism.
