Chordates are often divided into 5 main groups. These groups are, fish,amphibians,reptiles,birds, and mammals. Each group of chordates have their own unique set of traits and characteristics.

If you live in the united states,canada, or Australia, you use a 12 hour system for telling time.
If you look at this clock it is 7 oclock. However is this 7 oclock in the morning or 7 oclock at night. This is where am and pm help
.The 12-hour system divides the 24 hours of a day into two periods lasting 12 hours each. The first 12-hour period is designated as am. It runs from midnight to noon. The second period, marked pm, covers the 12 hours from noon to midnight.
AM comes from the latin phrase ante meridiem, which translates to, before midday)
and p.m. from the Latin phrase post meridiem which translates to, past midday
There are 24 hours in a day, this requires the hour hand to pass the 12 twice.

Learn about the first four planets called the terrestrial planets and the gas giant planets called the Jovian planets.
The terrestrial planets include Mercury, Venus, Earth, and Mars.
These planets are small, rocky, and close together.
The Jovian planets in Jupiter, Saturn, Uranus, and Neptune.

Steps of cellular respiration
All organisms use respiration in order to produce energy.
In this video I review the basics of cellular respiration.
Welcome to MooMooMath
All living organisms practice cellular respiration.
This includes bacteria,fungi,plants, and animals
Why is cellular respiration important?
Because living organisms generate energy with cellular respiration
In plants and animals cellular respiration takes place at the mitochondria.

Think of the mitochondria as the power plant of the cell because the energy of the cell is generated at the mitochondria
Just like these powerplants and turbines generate power for their city.

Cells that need more energy have more mitochondria like muscles

At the mitochondria sugar combines with oxygen to produce carbon dioxide plus water and energy in the energy in the form of atp

Limiting Factors in an ecosystemAny biotic or abiotic factor that restricts the number or production of organisms is a limiting factor.

Take this ecosystem found in the fishbowl
The limiting factors would be the size of the bowl, amount of water, will limit the number of fish that can survive in the fishbowl

Limiting factors can be dependent limiting factors and independent factors

Dependent limiting factors depend on the number of organisms
For example, the amount of food available for each organism depends on the number of organisms
An independent limiting factors does not depend on the number of organisms.
For example, the amount of rainfall does not depend on the number of organisms

You also have

Density-Dependent Factors
A limiting factor that depends on population size is called a density-dependent limiting factor.

Density-dependent limiting factors include:
• competition
• predation
• parasitism
• disease

Here is a list of abiotic limiting factors
Sunlight
Climate
Temperature
Water
Space
Soil chemistry
Fire
Natural disasters


Biotic factors limiting factors
Number of plants
Number animals
Amount of competition
Number of decomposers
parasites
Disease causing agents

Wetlands are ecosystems found on Earth that are covered with water for most of the year.
In this video, I cover the difference between a swamp which has trees and a marsh that mainly has grass and reeds.
I also cover a bog that receives on rain or snow and fen that has a water source feeding it.

Compare and contrast tornados, hurricanes, and thunderstorms Each of these extreme weather events can cause great damage and are very powerful but they each form in a unique way.

Symbiosis or Symbiotic Relationships are interactions between different species. In this video, Let's take a look at three types of symbiotic relationships.
Mutualism in which both win.
Commensalism in which one organism wins and the other is neutral.
Parasitism in which one wins and the other is harmed.

Learn the planets in order along with some interesting planet facts.
The planets in order are,
Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune
** Please note Uranus has the coldest recorded temperature and Neptune has the coldest average temperature.***

Learn how to balance chemical equations.
Follow these steps when balancing a chemical equation
Draw a line vertical at the arrow
Count the number of atoms on each side of the vertical line.
Start with the metals and balance the metals.
Next work with the nonmetals and then move on to hydrogen and other elements.
Remember you cannot change the subscript, only the coefficient.

If you make a model of the distance of the planets on a large field you get an impression of how far away the planets and closest stars really are. In this model, 1 foot represented 15,500,000 miles.
The Earth is only 6 feet away but Pluto ends up being 236 feet away.
The closest star Alpha Centauri ends up being 305 miles away, Imagine that, 305 miles away on this scale when Neptune is less than 100 yards away from the sun. It is hard to imagine these kinds of distances.

Learn how to find the area of a circle.The area of a circle uses the formula is pi times radius squared.

Types of Biodiversity
Biodiversity is the variety of life in an area which is determined which is determined by the number of species in that area.
the totality of genes, species, and ecosystems of a region
As biodiversity increases so do the health of the ecosystem increases.
Think of it as if you were running a business.
You want your business to be healthy and make money. Imagine you sell shirts. If you only sold a black shirt with a heart you are limited and if white shirts go out of style you are out of business. If you have a variety of shirts as fashion changes you are better able to adapt to these changes and continue to make money.
As biodiversity increases the ecosystem has a greater ability to adapt to changes.
Biodiversity is broken down into three types
Genetic diversity
Species diversity
Ecosystem diversity

Levels organization in Biology
Life can be classified from simple to more complex. The levels of organization can be summarized as,atom,molecule,macromolecule,cell,organ,tissue,organ,organsystem,organism,population,community,ecosystem,biosphere.
