Kingdom Monera-Bacteria-Archaebacteria
The kingdom monera consists entirely of single cell organisms. Members of the kingdom are found just about everywhere on earth. They are located in popular springs,cow's stomach, and nearly every surface on earth.
All members of the kingdom don't have a nucleus or membrane bound organelles. Accordingly, they are categorized as prokaryotes.
They have a cell wall, genetic material, cytoplasm, and ribosomes.
Bacteria get their energy in lots of different methods.
Some get strength from sunlight,others get strength from chemicals like CO2, while some break down organic and natural material
This kingdom is split into two groups.
Archaebacteria and bacteria
Archaebacteria is found in extreme environments.
For instance, some are in the tummy of a cow, hot springs, the dead sea, and swamps or marshes.
They have a different type of cell wall than bacteria and so are antibiotic resistant.
Bacteria are found just about everywhere.
They are very important to life on earth.
Although some cause disease, virtually all are extremely helpful to us.
They break down food inside our stomach, help the nitrogen cycle, and actually help make a few of our food like sauerkraut.
We could not survive without bacteria.
Bacteria could be classified by their shape.
Coccus includes a sphere shape
Spirillum have a good spiral shape
Bacillus have a good rod shape.
Most organisms of monera kingdom reproduce asexually in an activity called binary fission, however, many reproduce sexually in an activity called conjugation.

Learn how to find the area of a sector which is similar to a pizza. The formula for finding the area of a sector equals the measure of the angle over 360 times pi radius squared.
m/360*πr2
The most common sector is a semi-circle which divides a circle in half.

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

Learn how to simplify 4th roots. Complete a factor tree and find groups of 4 in order to pull out numbers from the radical symbol

What are the factors that allow the Earth to sustain life?
Life has been around for a long time. How does the earth help life on earth keep going and going and going.
I would like to look at three processes and one force that work together to help sustain life.
First, life is sustained by the flow of energy from the sun through the biosphere.
The biosphere is any location on earth that has life.
Plants contain chloroplasts which have the ability to convert sunlight into sugar.
Plants combine carbon dioxide, water and sunlight into glucose.
Animals eat plants and the energy from the sun is transferred to the animal.
Other animals eat these animals and the energy from the sun is spread throughout the ecosystem
The next process is the cycling of nutrients within the biosphere.
The earth has several biochemical cycles that recycle important chemicals
These cycles move chemical substance from the biotic and abiotic compartments of Earth. There are biogeochemical cycles for carbon, oxygen, nitrogen, phosphorus, sulfur, and water;
These cycles keep recycling these important chemicals so that we don’t run out of these chemicals.
Life has the ability to duplicate itself. It can be the offspring of two adults or bacteria that uses binary fission to rapidly make copies of itself.
Finally, gravity is the force of attraction between objects.
Gravity hold life on earth and also holds our atmosphere close to the earth.
The atmosphere contains important gases like oxygen which are essential to life.
Without gravity, the earth would not have an atmosphere and life as we know it would go away.
So there you go,
How life keeps going and going and going

Learn how to calculate the scale factor. You can use scale or model or scale over the actual or the original in order to determine the scale.factor.

Our blood helps keep us alive.
Your blood makes up around 7% of your body weight
This equals between 1 and 1 and a half gallons 4.5 to 5.5 liters
Your blood is considered a connective tissue.

Our blood has many important functions.
Here is a list of some of the major jobs
Transports oxygen to each cell.
Removes waste material like carbon dioxide.
Helps regulate your temperature and ph levels.
Fights disease and helps the immune system do its job.
Blood transports nutrients, such as sugars, fats and proteins, amino acids,
Along with hormones which are your chemical messages of the endocrine system.
It is made up of red blood cells, white blood cells, platelets, and plasma.

In this video, I show you how to find the exact square root of a number using a factor tree.
A factor tree allows you to find the prime numbers of a number.
Once you know the prime numbers then you can easily find the square root.
In this video, I find the,
The square root 50
The square root of 9
The square root of 25
The square root of 12

How to simplify square roots. I give step by step instructions on how to simplify a square root. Once you see a couple examples I think you will find the process pretty easy.

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.

Learn how to find the cube root of 64. The number 64 is a perfect cube.

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.

What makes an arachnids an arachnid? Spiders and mites are examples of arachnids. First arachnids are arthropods and in addition, they have 8 legs, no antennae, and no wings.
Spiders are arachnids and come in a variety of sizes and shapes.
Spiders are not insects, but instead, they are Arachnids.
Although a spider and insect have many of the same traits spiders have only two body segments and eight legs instead of six.

Plant root structure explained.
The root of a plant helps anchor the plant and absorb water and nutrients from the soil.
There are two main types, a taproo nd a fibrous root.
