The cell membrane surrounds the cell and protects the cell, communicates with other cells, and controls what enters and exits the cell.
The cell membrane is made of phospholipids which have a polar and nonpolar end.
The cell membrane also has proteins and carbohydrates.
In this video, I cover what the cell membrane is made of and the structure and function of the cell membrane.

In this video, I would like to show some examples of diffusion.
Diffusion is when objects move from an area of high concentration to an area of low concentration.
Check out this example, of diffusion.
You can another simple example of diffusion when you watch the food coloring diffuse into the water.
If you take an egg and soak it in vinegar and then place it in water, the water will diffuse into the egg causing it to get larger.
If you place sugar into coffee it will diffuse out into the coffee.
Watering plants diffuses the water into the plants
When you go into Starbucks and smell the coffee smell the smell of the coffee has diffused through out the coffee shop.
You can soak a gummy bear in water and the water will diffuse into the gummy bear. and it will get larger.
Those are several examples of diffusion.
When objects move from high concentration to low concentration.
Thanks for watching and MooMooMath and Science uploads a new Math and Science video everyday.

What is a ribosome? A ribosome is an organelle found in plant, animal, and bacteria cells.
They are very small yet very important because they make proteins. Ribosomes use a process called translation to make proteins.

If you would like to learn more about proteins and their importance this video will help.

Pathway of Air Flow
Our journey of oxygen into the lungs and back begins when the brain stem sends a message to the diaphragm which is a muscle under the lungs.
As the diaphragm moves down the lungs expand.

Air enters the nose and mouth and enters the nasal passages.
Your nose and nasal passages have tiny hairs called cilia and mucus that help filter dirt and pollen out of the air.
The air next moves to the pharynx which is located at (the back of the mouth)
From the pharynx, it moves to the larynx which is commonly called the voice box.
the voice box (makes sounds when air
passes over the vocal cords)
Epiglottis: the flap of connective tissue that covers
over the larynx during breathing
It stands open during breathing, allowing air into the larynx. During swallowing, it closes to prevent choking on food

From the larynx, air travels to the Trachea which is a rigid tube made of cartilage.
The trachea leads into two tubes called the left and right bronchus
These tubes continue to branch until you reach a tiny air sac called a alveoli
At the alveoli, oxygen diffuses into the capillaries and carbon dioxide diffuse into the alveoli and is exhaled.
This process is repeated over and over again.

Kingdom Animalia Characteristics-Animal Kingdom
The kingdom Animalia comprises of most of the organisms we face daily. Your pet dog belongs to the kingdom, along with snakes, frogs, cats, and humans.
There is a huge variety of creatures in this kingdom, but animals have these common characteristics.
All animals are eukaryotes this means the have a nucleus and membrane-bound organelles.
All animals are multicellular
All are heterotrophs
No cell wall
Two major categories.
Vertebrates which have a backbone and invertebrates that do not.
Invertebrates don't have a backbone or spine.
They include your sponges, cnidarians,several types of worms, mollusks, arthropods, echinoderms starfish,sea cucumber,sea urchins
Most of the animals on the planet are invertebrates.
Vertebrates have a backbone. Examples include,
Lancelets,lampreys,various kinds fish,amphibians,reptiles,birds, and mammals.
Animals are found on every continent and also have adaptations that help them survive.

Equivalent Fractions look different but measure the same thing! I place several equivalent fractions on a number line in order to help you see that they measure the same things. Remember, a fraction measures parts of a whole.

Learn how biogeochemical cycles work. Important elements along with molecules like water are conserved by moving between living factors called biotic factors and abiotic factors which are nonliving factors. You can remember the elements that have biogeochemical cycles using CHNOPS
Carbon, Hydrogen, Nitrogen, Oxygen, Phosphorus, Sulfur.
Each of these elements has its own unique cycle and path from biotic and abiotic factors.

Protein synthesis in simple terms. I cover the steps of transcription and translation. The overall process involves DNA unzipping when RNA polymerase attaches and a strand of RNA is created. Rna is different than DNA because it contains the base Uracil instead of Thymine. This step is called transcription.
I next show the difference between transcription and translation by showing how the mRNA leaves the nucleus and attaches to a ribosome.
At the ribosome codons and anticodons put the amino acids together in the correct order to form the protein.

Mesozoic EraIn this video I would like to talk about the Mesozoic era on the geologic time scale.
The Mesozoic era is part of the Phanerozoic Eon along with the Paleozoic and Cenozoic eras.
Mesozoic means “middle animals” and is a time of rapid change.
This era has also been called the age of reptiles and age of dinosaurs
The Mesozoic era was roughly 65 million years to 250 million years ago.
Let’s hit several highlights of this era
The Mesozoic era began after a mass extinction.
The shape of the continents looked different. At the beginning of this era, there was a super
Continent called Pangea. Over time this supercontinent broke apart and the continents started drifting apart.
The climate was warmer than today
The first mammals appear but are very small and they don’t begin to thrive until the Cenozoic era.
Dinosaurs also appear and begin to scatter and prosper.
The dinosaur population peaks during this era.
However, at the end of this era, the dinosaurs die off
The first birds appear and begin to scatter throughout the world.
The dominant plant is a cone-bearing tree and plants
At the end of this era, flowering plants begin to appear
So there we go the Mesozoic era,
Dinosaurs and cone-bearing plants

How do we breathe? The lungs and diaphragm work together to bring oxygen into the lungs and to move carbon dioxide out of your lungs.
The diaphragm is a large muscle that is found under your lungs. Your lungs are actually composed of millions of tiny air sacs and depend on the diaphragm in order to inflate
Your rib cage also helps out by having cartilage which allows the rib cage to expand and contract.
When you take a deep breath your diaphragm moves down and a low-pressure area is created and air flows into your nose and mouth. This process is your respiratory system hard at work.
Air enters the nose and mouth and enters the nasal passages.
Your nose and nasal passages have tiny hairs called cilia and mucus that help filter dirt and pollen out of the air.
The air next moves to the pharynx which is located at (the back of the mouth)
From the pharynx, it moves to the larynx which is commonly called the voice box.
the voice box (makes sounds when air
passes over the vocal cords)
Epiglottis: the flap of connective tissue that covers
over the larynx during breathing
It stands open during breathing, allowing air into the larynx. During swallowing, it closes to prevent choking on food

From the larynx, air travels to the Trachea which is a rigid tube made of cartilage.
The trachea leads into two tubes called the left and right bronchus
These tubes continue to branch until you reach a tiny air sac called a alveoli
At the alveoli, oxygen diffuses into the capillaries and carbon dioxide diffuse into the alveoli and is exhaled.
As you exhale the diaphragm moves upward and carbon dioxide and airflows out.

How does oxygen enter the body. The respiratory system is designed to exchange oxygen for carbon dioxide. The respiratory system is vital for the production of ATP. The mitochondria uses oxygen in order to produce ATP. In addition, it is designed to get rid of the waster product carbon dioxide.

Quantitative Data vs Qualitative Data

Additional Information on Qualitative vs Quantitative Data
https://moomoomath.com/qualita....tive-vs-quantitative

Data can be divided into two groups called quantitative and qualitative data
Quantitative data is numerical
Qualitative Data id descriptive data
Let’s look at examples of both
Examples of quantitative data would be
The number of pets, time of day, the temperature outside
Quantitative data can be graphed
If you count or measure, you are collecting quantitative data
There are two types of quantitative data, discrete and continuous
Discrete data is usually data you can count and continuous data is usually data you measure. I have a separate video on these two types of data.
Qualitative is descriptive or observations and uses words
For example, the color of a house, smell of a sock, texture of a shirt
Quantitative or Qualitative
Consider a cat
Quantitative Data would be the cat has 4 legs and weighs 10 pounds
Qualitative data would be the cat is yellow, and has soft fur
A bookshelf
Quantitative would be you have 50 books and is 150 centimeters tall.
Qualitative data would be it is multi-color and has a smooth texture

In this video, I show real-world examples of alleles.
An allele is different forms of the same gene which results in traits that look different.

A trait is a characteristic that can be passed from one generation to another.

The different forms of the same gene are the alleles
How about a couple more real-life examples

Eye color would be the trait
The different color of eyes would be the alleles

The trait is having hair

Black or blonde hair color

Your height is the trait
If you are Six feet or five feet tall

Allele different forms of the same trait.
