What are diatoms?
Diatoms are a major group of algae and are among the most common types of phytoplankton.

Diatoms are unicellular organism, although they can form colonies
They have cell walls made of glass

Diatoms belong to kingdom Protista

There are at least 100,000 species of diatoms have been discovered,
Diatoms exist in large numbers in most bodies of water throughout the world. In fact, just one quart of seawater can contain millions of diatoms
They are primary producers and create and are a very large food source in the ocean


Diatoms are autotrophs and produce energy by photosynthesis.As a result,, diatoms need sunlight, carbon dioxide, and water. They are found in the ocean, fresh water, and even moist topsoil

Many Diatoms are microscopic, but some measure a millimeter across.

Diatoms contribute enormous amounts of oxygen to our atmosphere.

Two basic forms of these organisms exist. They are known as Centrales Centrales have radial symmetry and are most often found in oceans and are wheel-shaped. They can be found drifting near the surface, sunlight and absorbing nutrients.Pennales tend to be elongated

Many Pennales live in fresh water streams, swamps, ditches, or on the bottoms of shallow regions of oceans and estuaries.

The deciduous forest biome is known for having four seasons and trees that drop their leaves in the winter.
This biome is located in the eastern half of the United States, Canada, Europe, parts of Russia, China, and Japan.
The deciduous forest has moderate winters and warm summers. It receives around 50 inches of rain a year. This rainfall allows trees like oak, maple, and beech trees to grow in this forest.
You will find bear,fox, and deer in this biome

Excretory system
The excretory system removes waste and toxins from the human body.
Your skin eliminates waste by sweating.
Your lungs eliminate carbon dioxide.
Your kidneys filter over 180 liters of blood in order to produce urine.
The kidneys filter waste like urea. This liquid that is collected is called urine.
Your kidneys are made up of millions of filtering units called nephrons.

The spleen is located in the upper left abdominal cavity, just beneath the diaphragm, and next to the stomach. It is similar to a lymph node in shape and structure but it is much larger.
An easy way to remember the anatomy of the spleen is the 1×3×5×7×9×11 rule. The spleen is 1" by 3" by 5", weighs approximately 7 oz, and lies between the 9th and 11th ribs on the left-hand side.
Your spleen is considered part of the lymphatic system.

the spleen consists of two types of tissue called white pulp and red pulp. The white pulp is lymphatic tissue consisting mainly of lymphocytes around arteries. The red pulp consists of sinuses filled with blood and lymphatic cells,

As blood is filtered through the spleen old and damaged red blood cells are removed from the blood. In addition, the spleen produces lymphocytes in response to invading pathogens found in the blood. The spleen is like a large lymph node that filters blood instead of lymph looking for invaders like harmful bacteria. White blood cells stored in the spleen help remove and eliminate these invaders. It is particularly helpful when fighting meningitis and pneumonia

The spleen also stores blood. The sinuses in the red pulp of the spleen are filled with blood and can be used in case of an emergency.

You can live without your spleen. your immune system won’t shut down without a spleen, but it won’t operate as efficiently.

Find the cube root of 8 and 27 without a calculator.

Learn the difference between independent and dependent variables in research.
The independent variable can stand alone and is the variable that is being changed or manipulated.
The dependent variable is the variable that is being measured.
Learning the difference between these two types of variables can be very helpful in Science and any type of experiment.
I also cover how to graph these two types of variables.

Detrivores are heterotrophs that feed on decaying organic matter in an ecosystem. Common examples of detrivores include worms and millipedes. Without decomposers and detrivores, the earth would be covered up with dead organisms.
