Let's go through the different levels of Biological organization. I start at the organism and finish at the Biosphere. However, the smallest level of life is a cell. Cells can combine to make tissues, which may combine to make an organ, and a group of organs may make an organ system.

An organism refers to a living thing that has an organized structure, can react to stimuli, reproduce, requires energy plus grows and adapts
Examples include animals, plants, fungi, protists, and many, many more.

Whenever you get a group of the same type of individuals together, like this group of Penguins or these wolves, and horses, or plants you have a population. The organisms are all of the same species.

If you have several different populations living together you have a community.
A community does not include the non-living factors also called abiotic factors.

An ecosystem is a community of living factors called biotic factors and non-living factors called abiotic factors interacting and living together.
A desert can be an ecosystem.
A forest can be an ecosystem.
A pond is an ecosystem,and even a rotting log can even be an ecosystem.
An ecosystem is a community of living and non-living objects living together in a particular area.

A Biome is a large ecosystem that has formed in response to the physical environment[1] in which they are found and a shared regional climate. Examples include a desert, tropical rainforest, and a deciduous forest.
The Biosphere is part of the earth where life exists. It is the sum of all the ecosystems on Earth.

The Golgi body is vital for the health of a cell. It is sometimes described as a post office, or a distribution center because it repackages proteins and chemicals and ships them to locations in the cell.
The Golgi body which is also called the Golgi apparatus is found in eukaryotic cells.
The Golgi body receives proteins from the rough er and repackages the proteins and chemicals into vesicles that are sent out to three locations. Some vesicles become lysosomes, others travel to the cell membrane and provide proteins for the membrane, and other vesicles travel outside the cell-like vesicles containing insulin so it can be released into the bloodstream.

A scientific name uses a two part naming system called binomial nomenclature.
The first part on the name describes the genus the organism belongs to, and the second part is the species.

Friction is the force that opposes motion between any surfaces that are in contact. There are at least four types of friction: static, sliding, rolling, and fluid friction. Static, sliding and rolling friction occur between solid surfaces. Fluid friction occurs in liquids and gases

Static friction occurs when an object is resting on a surface. The static friction between the boots and the snow allows this person to stand and shovel snow.
When you rub your hands together you experience sliding friction.
When you ride a bike you depend on the rolling friction of the tires.
Sky diving depends on fluid friction between the air and the parachute to slow down.

In this video, I cover many real-life examples of friction and how friction helps you in everyday life.

Vertical Angles Explained
Vertical angles in Geometry occur when two lines cross one another. The lines share a common vertex and are opposite each other.
Vertical angles are congruent which means the angle measure is equal. In addition two pairs of vertical angles are created when the lines cross.

6 kingdoms of classification in 3 minutesThe 6 kingdoms are
Animal
Plant
Fungi
Protist
Eubacteria
Archaea

The Animalia kingdom is an extremely diverse group of individuals
Some animals are giant, like the blue whale, whereas others are tiny, like an ant Some have complex nervous systems and are very intelligent, whereas others are simpler, like the sponge.
Some common traits
Animals are heterotrophs, which means they eat other organisms for food.
Animals are multicellular, meaning they are made up of more than one cell.
Animal cells are eukaryotic, animal cells contain membrane-bound organelles, or tiny organs, which help the cell undergo certain processes it needs to function.

In addition, animals use the protein collagen to attach cell tissue together.
Finally, animal cells are diploid, meaning each cell has a two pair of chromosomes. One pair is is usually from mom and one from dad
Plantae kingdom contains large trees and flowers. Let’s see what they have in common.
First plants are autotrophs. This means they can get their food from the sun.
Next, they are eukaryotes and contain a cell wall and plants are multicellular

Fungi range from mushrooms to yeast
Some mushrooms are multicellular and others a unicellular
Fungi are eukaryotes and contain a cell wall
Fungi are also heterotrophs
Some fungi are decomposers while others are parasites

Protista
Kingdom Protista has been called the junk drawer kingdom. Protist range from single-cell organisms like euglena to multicellular kelp Some are plant-like, others animal-like, some fungi like
As the catchall kingdom for eukaryotic organisms if it is a not animal, plant, or fungi it is thrown in the protist kingdom it is not surprising that very few characteristics are common to all protists.
Some protists are heterotrophs but others are autotrophs.
Most protists are found in moist environments

Eubacteria single cells prokaryotes which mean they don’t have a nucleus or membrane-bound organelles
Have a cell wall, some move with a flagella
Eubacteria help digest food, make us sick, or help make yogurt

Archaea are prokaryotes like bacteria but are structurally different many handle extremes
Extreme temperatures, extreme salty conditions, or little or no oxygen

Local winds are winds that do not blow for great distances. In this video, I cover two major types, sea and land and mountain and valley winds. These local winds occur because the land and sea heat up and cool at different temperatures and this produces wind due to low and high-pressure areas.

Waves such as light and sound waves can bend, slow down, and speed up. In this video, I define and explain the difference between reflection, refraction, and diffraction.

Desert Biome is found on every continent. A desert is an area that receives rainfall of 10 inches or less a year.
Deserts can be very hot or very cold.
For example, the Sahara desert is the largest hot desert, and the Gobi desert in China is very large and cold most of the year.
Animals and plants in the desert must have adaptations that allow them to survive on little water.

Learn about the steps of protein synthesis, the creation of long chains of amino acids from DNA.
It begins in the nucleus with transcription and moves to the ribosome where translation takes place.
Translation occurs in the nucleus when RNA polymerase attaches to the DNA and unzips a portion of the DNA.
mRNA or messenger RNA begins to fill in the DNA.
RNA is similar to DNA but contains Uracil instead of thymine.
This strand of mRNA leaves the nucleus and travels to a ribosome where translation will begin.
The messenger RNA will be read three units at a time called a codon.
The anticodon on the transfer RNA aligns with the correct codon and delivers an amino acid.
This continues and a polypeptide chain begins to grow.

Nucleus Structure
What the parts of the nucleus?
Cell parts and function-I have always heard that the nucleus is the brain of the cell. But why is it the brain, and what are the major parts of the nucleus?
The nucleus is a large organelle. In fact, you can see the nucleus with a compound microscope.
Here it is inside a cheek cell.
I’m going to look at four main components of a nucleus and the role each part plays.
The nucleus is surrounded by a nuclear membrane. It is very similar to the cell membrane, and it is composed of two layers. It protects and houses the other parts of the nucleus.
You can also find ribosomes on the outside of the nuclear membrane.
Up next are nuclear pores. These are openings found on the nuclear membrane.
They allow items to move in and out of the nucleus. An example would be the mrna. It would travel through a nuclear pore to leave the nucleus.
Nucleoplasm This is a gel-like material found inside the nuclear membrane. You will find the DNA suspended in the nucleoplasm
Nucleolus. This is almost like a nucleus inside the nucleus. It has a very high concentration of DNA,
It is also the site of transcription which is the starting point of protein synthesis.
This is how the nucleus controls the cell. It has all the information on how to make stuff like proteins inside the cell. These proteins are used for many purposes inside the cell.
Ribosomes are also made at the nucleolus
All eukaryotic cells have a nucleus and bacteria and other prokaryotic cells do not have a nucleus.
