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.

Commensalism Examples
Commensalism is a symbiotic relationship in which one organism benefits and the other organism is neither helped nor harmed.
The examples include egret bird and cattle, orchids and trees, barnacles, burdock weeds, and remora

Learn how to code from DNA to mRNA to tRNA to amino acids.DNA is made up of four bases Adenine Cytosine Guanine and Thymine
Let's shorten this to ACG and T
A pairs with T and G pairs with C
So if we have this strand. It moves from 5 to 3
For a complementary strand, you will have
a will pair with t, t with a g with c and you can watch the rest.
Now messenger RNA is similar to DNA but instead of thymine, you will have uracil.
After decoding the mRNA and tRNA you can use an amino acid chart and find the correct amino acid.

At 2:21 I mislabel tRNA. Sorry for the mistake. Here is an updated video correcting the mistake.

Kingdom of Protista
In this video, I review the kingdom Protista
A protist is a eukaryote that is not an animal, plant or fungi.
The kingdom protista is called the junk drawer kingdom because if a eukaryotic organism is not placed in the other kingdoms it is considered a protist.
There are three main types of protists, plantlike,animal-like and funguslike.
Some common examples of protists include amoeba , paramecium, kelp,algae,diatoms, euglena, and dinoflagellates.

Learn about the Phosphorus cycle. Phosphorus is an essential nutrient for living organisms. It’s a building block of nucleic acids, like DNA, and phospholipids that form our cell membranes. It is also essential for plant growth.
In the natural world phosphorous is never encountered in its pure form, but only as phosphates, which consists of a phosphorus atom bonded to four oxygen atoms
Phosphate compounds are found in sedimentary rocks, and as the rocks weather—wear down over long time periods—the phosphorus they contain slowly leaches into surface water and soils. Volcanic ash and fertilizer can also be significant phosphate sources.

A surface wave is a wave in which particles of the medium undergo circular motion. Surface waves are neither longitudinal pause nor transverse. Pause Kinda like a liger
In longitudinal waves, the particles move parallel to the disturbance, and transverse waves the particles perpendicular relative to the direction of the disturbance. In a surface wave, it is only the particles at the surface of the medium that undergo the circular motion. The motion is both at right angles and parallels when the particles travel in a circle.

The circular motion of particles tends to decrease as you move further from the surface.

Large bodies of water like the ocean contain surface waves.

During an earthquake, Rayleigh waves are produced and are a type of surface wave that travels near the surface of solids. The circular motion of the medium near the surface produce both longitudinal and transverse motions

The Phosphorus Cycle is essential for life on Earth. It is considered a biogeochemical cycle.
In the video, I cover the phosphorus cycle steps.
Phosphorus is not found in the atmosphere but is found in rocks and is released by weathering.
Plants and animals absorb the phosphorus that is washed into the soil.
Eventually, the phosphorus is washed into sediment that is compressed into rock.

How do thunderstorms form? In this video, I will cover the basics of these exciting storms.Here is how a thunderstorm forms
Step 1 Warm moist air is heated and begins to rise upward.
Step 2 As this warm air rises it begins to cool, condenses and begins to form clouds
Step 3 This warm air will continue to rise and will encounter cold air which will cool the moisture in the clouds and ice may form
Step 4 Eventually the cooled moisture and ice will begin to fall to the earth This action creates a downdraft
5. The updrafts continue feeding warm humid air and the falling moisture create downdrafts. This creates convection currents. You can see what convection currents look like. The warm water is in red and the cool water is blue.
These convection currents create the most violent stage of the thunderstorm
Lightning and strong winds are produced
6. Eventually the downdrafts will stop the updrafts of warm air
7 When the warm moist air is cut off the storm begins to dye off

There are three main types of thunderstorms; orographic, air mass, and frontal.

Difference between habitat and niche-Ecology

A habitat is an ecological area where a plant or animal lives. It may be an island, a tree, or rock ledge. The habitat is where an individual can find food, shelter, protection, and mates.
A niche is a role or position that an individual has in its environment. A niche may also involve what the individual eats, how it interacts with other living things, and also how it interacts with the non-living factors.

I have taught at the same school for many years and the same room for many of these years. This would be my habitat. I teach Life Science at this building and this is my niche. Mrs. English teaches English and Mr. Kay teaches social studies. We all live in the same habitat and we all have our own niche.
Let’s take a look at a real world example.

The Galapagos Islands are islands located 605 miles to the west of South America. There are several types of finches that live on the islands. Their habitat would be the Galapagos Islands and the different Finches have their own niches. The different finches eat different types of food.

The warbler finch has a thin beak for eating insects. A ground finch has a short beak for eating seeds left on the ground.
Cactus finches eat cacti seeds.
Each Finch has their own niche that allows them to survive and prosper in the same habitat as other finches.

Heat is the transfer of energy from objects of different temperatures. As objects warm-up or cool down their kinetic energy changes. Kinetic energy is the energy of motion.
In this video, I focus on three ways heat can be transferred,
Conduction, Convection, and Radiation.
Conduction involves direct contact between objects and usually occurs among solids.

Convection is caused by unequal heating and the density of the different objects causes movement of fluid away from the heat source.

Radiation occurs without objects touching and occurs in space.
For example, the energy of the sun warms objects on Earth due to radiation.

I show several examples or demonstrations for each type of heat transfer.

Conduction, Convection, Radiation

Anaerobic Respiration Fermentation

Anaerobic respiration, also called fermentation, occurs when cells need energy but there is no oxygen for aerobic respiration. As a result, cells convert glucose into either ethanol or lactic acid.
Alcoholic respiration occurs in plants and yeast.
Lactic acid fermentation occurs in animals.

Acceleration is the measure of the change in velocity over time. The change in velocity can be a change in speed, direction or both.

The formula for average acceleration is
Final velocity-Initial Velocity over Time it takes to change

Acceleration is expressed in meters per second squared

Learn how to divide decimals. The key is to make sure the divisor doesn't have a decimal. You can always move the decimal to the right, but if you move the decimal for the divisor you need to also move the decimal of the dividend.

Introduction to metabolism | Biology|
You may have heard that you have a fast metabolism or a slow metabolism

But what exactly is your metabolism?

Metabolism is the sum of all chemical reactions within the cells of living things.
Take a look at this summary of all of the chemical reactions taking place in a human.
The chemical reactions of metabolism are organized into pathways in which one chemical is transformed through a series of steps into another chemical, with the help of enzymes.
An example of a pathway is cellular respiration in which glucose and oxygen are transformed into carbon dioxide water and ATP which is used for energy

You can break metabolism down into three main categories.

The chemical reactions used for the conversion of food to energy
The conversion of food into building blocks used to make items like proteins
The chemical reactions needed for the elimination of waste

Enzymes are crucial to metabolism Enzymes help speed up chemical reactions The molecules upon which enzymes may act are called substrates and the enzyme converts the substrates into different molecules known as products.
Almost all chemical reactions in the cell need enzymes in order to occur at rates fast enough to sustain life
There are over 5000 chemical reactions that occur in plants,animals, and microbes that are controlled by enzymes.

Most of the structures that make up animals, plants and microbes are made from three basic classes of molecule: amino acids, carbohydrates and lipids
Many chemical reactions focus on making these molecules during the construction of cells and tissues, or by breaking them down and using them as a source of energy during digestion and cellular respiration.

These chemicals can also be joined together to make DNA and proteins.

So there you go metabolism the sum of chemical reactions that take place in living things.

You can test for proportionality on a graph by looking at various properties
A proportional graph will always go through the origin ( 0,0 )
A proportional graph will be a straight line
If you list points ( ordered pairs) from a graph you can create ratios and see if they are constant
