Learn the difference between a autotroph and a heterotroph. All plants and other organisms that produce their own food in an ecosystem are called autotrophs. Or self feeders
An Autotrophs is an organism that collects energy from sunlight or inorganic substances to produce food.
A Heterotroph is an organism that gets its energy requirement by consuming other organisms.
They are also called consumers
A heterotroph that eats only planed is called a herbivore
Heterotrophs that eat other heterotrophs are called carnivores. Lions,wolves
An organism that eats plants and animals are omnivores.

In this video, you will learn about the Circulatory SystemThe circulatory system, is the transportation system of the body and is responsible for the flow of blood in the body. The major structures that make this possible are the heart, blood vessels, and blood.
The heart pumps blood in order to move nutrients oxygen, carbon dioxide disease-fighting white blood cells, and hormones to and from the cells in the body
The circulatory system has two main types of circulation.

The pulmonary
The Systemic
Pulmonary circulation travels from heart to the lung where your blood picks up oxygen and back to the heart
Systemic circulation is from the heart to the body

Your heart has four chambers that is used to pump blood throughout your body.

Two Atria - which are the upper chambers.
Two ventricles - these are the lower chambers
The left and right side of the heart is divided by the septum

Blood Vessels carry blood throughout the body.
Arteries carry blood away from the heart and veins carry blood towards the heart

Capillaries, which are the smallest blood vessels in the body create a network of vessels connecting veins and arteries.
In summary, the heart pumps blood to the body through the arteries and returns blood to the Body through the veins

You have around 1.5 gallons of blood in your body
It is composed of several different types of cells.
The first type of blood cell is the red blood cell. Red blood cells help carry oxygen

The second type of blood cell is known as the white blood cell and helps fight pathogens

The third type of cell is the platelet and create blood clots.
These blood cells are found in a liquid called plasma which consists of water along with electrolytes and some proteins and hormones

In summary, The job of the circulatory system is to circulate blood to and from cells in the body in order to transport nutrients and oxygen and remove carbon dioxide and waste.

In this video, you will learn about transport across the cell membrane. I cover active and passive transport, diffusion, osmosis, and endocytosis and exocytosis.
Passive transport involves diffusion and osmosis and does not require energy. Objects move from a high concentration to a low concentration.
Active transport requires energy.
I answer questions like, is facilitated diffusion active or passive transport.

A keystone species has a large impact on their habitat given their size and numbers. Their daily activities impact all kinds of other species.
A keystone is a central stone at the summit of an arch, locking the whole together.
A keystone species helps keep the entire ecosystem together
When beavers build their dam and lodge they basically create their own wetlands which impact many other organisms.
In addition, as the number of beavers increase the biodiversity of the ecosystem increases, and also the inverse fewer beavers less biodiversity
You may have heard the expression “ Busy as a beaver?”
That is because they, well stay busy building stuff.
Beavers build dams and a lodge to live in.
The dam transforms a stream or creek into a wetland.

There are several diferent types of estuaries.
An estuary is a body of water that has fresh water entering and is also open to the ocean. An estuary is a semi-enclosed, coastal body of water, that is connected to the open sea, with fresh water draining into it.
If you look at the state of Georgia you can see the Savannah river run through it. The Savannah river dumps into the Atlantic ocean and creates an estuary. Here is what a small portion of this estuary looks like.

Estuaries are known for their brackish water which is a combination of salt and fresh water. Estuaries have been called the "Nurseries of the Sea." because of the many phytoplankton that is found there help the food chain and provide food for many organisms.

Ocean stratification results when ocean water with different densities forms layers due to their properties. In this video, I show how differences in salinity can create ocean stratification which may result in ocean currents.
In the salinity demonstration, I have a container divided into two halves. On one side I have fresh water and the other I have very salty water. The two types of water are separated by a divider. When I lift the divider the salty water flows under the warm water and creates a current.

Learn about the arctic and alpine tundra.
The tundra is a very cold and dry biome.The arctic tundra is found in North America, Asia, and Europe and circles the arctic ocean and stretches southward down to the taiga.The alpine tundra occurs at any latitude and is found at high elevations of 10,000 feet and
above.
The alpine tundra is found above the tree line and does not have any trees
Because of the high elevation, the alpine tundra has a climate and rainfall similar to the arctic tundra.

Learn the basics of Lichen and Moss. In many places on Earth, you will find Lichen and Moss living beside each other. Although they may look similar they are very different. Lichen are actually a symbiotic relationship between fungi and cyanobacteria. Moss are nonvascular plants.

What happens during metaphase?
In this video, I would like to talk about the stage of mitosis called metaphase.
Mitosis consists of four stages and I always remember mitosis using PMAT
For Prophase Metaphase Anaphase Telophase
During metaphase the sister chromatids align in the middle of the cell.

However for this to happen a couple of things need to happen during prophase
During prophase the chromatin condenses into x shaped chromosomes.
Each half of the x is a sister chromatid and identical copies of the DNA
The two sides of the x shaped chromosome are attached at the centromere.

During metaphase spindle fibers appear These fibers create something called the spindle apparatus.
It consists of spindle fibers, centrioles, and another fiber called aster fibers
In plants, the centrioles are missing.
These spindle apparatus move to the poles of the cell.
The spindle fibers attach to the centromeres of the sister chromatids at the kinetochore.
After the spindle fiber is attached at the kinetochore the sister chromatid is pulled along the spindle apparatus and eventually end up in the middle of the cell.

Metaphase is the shortest stage of mitosis but is important because it helps ensure that new cells have correct copies of the chromosomes.

Mountain and Valley Breezes occur when the slopes of the mountain and the valley heat up and cool off at different rates. Valley breezes occur during the day and mountain breezes occur at night.

There are four main classifications of galaxies

Elliptical galaxies which are featureless and spiracle.

Spiral these have arms that spiral outward


Lenticular galaxies are given the symbol S0. These galaxies consist of a bright central bulge, similar in appearance to an elliptical galaxy, surrounded by an extended, disk-like structure.

Irregular galaxies are any other galaxy

The gas giants which are also called the Jovian planets include the planets, Jupiter, Saturn, Uranus, and Neptune.
These planets are not only huge but have no real surface, are composed of hydrogen and helium, and revolve around the Sun slowly.
These planets also have rings and many moons that revolve around them.

An overview of the transition metals. Which group of metals are silver, maybe gold and sometimes liquid? The transition metals
The transition metals are the elements found in groups 3-12.

Steps for cloning an animal
How Dolly the sheep was cloned and what we learned.
20 years ago Dolly the step was cloned from two sheets.
Here is how they cloned this sheep.
First, they took cells from the udder of one sheep. They grew these cells in the lab.
Next, they took the egg from another sheep and removed the nucleus.
These stopped cells were fused together and inserted into a female sheep who gave birth.
