Many times mass and weight are used to describe the same thing. However, these two measurements are different. In this video, I explain the difference between mass and weight.
Mass is a measure of how much matter something contains, which equals the number of atoms in it
Weight is a measure of how strongly gravity pulls on something

The SI unit for mass is kilograms
The SI unit for weight is the newton N

Sedimentary Rocks are rocks formed from rock fragments and organic matter.

Sedimentary rocks are formed from pre-existing rocks or pieces of once-living organisms. They form from deposits that accumulate on the Earth's surface or under the ocean. The particles that form a sedimentary rock are called sediment and may be composed of minerals or organic matter.
The following rocks are sedimentary Rocks
Shale, Conglomerate, Limestone, Sandstone

Soil horizon and profile explained.
Soil is essential for many activities like plants growing and much of the food we eat.
In this video, I cover the difference between soil profile and horizon and review the characteristics of horizons O A E B C R
o = litter
b = topsoil
e = eluviated
b = subsoil
c = parent material

Examples of parasitism

This innocent looking bird called a cowbird lays her eggs in another birds nest and expects the unsuspecting mom to raise their young. If this bird kicks her eggs out of the nest the cowbird may destroy her nest. This is just one example of parasitism.

Parasitism is a symbiotic relationship in which one organism benefits and another organism is harmed and in some cases may die.
Let’s take a look at examples

Mosquitoes These annoying pests will show up at most picnics and start trying to have a meal at your expense. mosquitoes are carriers, or vectors, for some of humanity’s most deadly illnesses, and they are public enemy number one in the fight against global infectious disease. Mosquito-borne diseases cause millions of deaths worldwide
In a similar fashion, ticks will do the same to you, dogs, livestock. The latch on to their host and start eating. Ticks can infect their host with many diseases including Lyme disease.

Many worms are parasitic.
Leech
A leech is a segmented worm that attaches to a host like you and gets a meal from their blood. They secrete a chemical that actually prevents the blood from clotting.
If present in great numbers on a host, these can be debilitating, and in extreme cases, cause death.

E. coli
There are hundreds of different types, or strains, of the bacteria E. coli (Escherichia coli). Most of these are harmless and live in the intestines of healthy people and animals. But some strains of E. coli make a strong toxin that can cause a severe infection.

Mistletoe This plant you will see high in trees is actually a parasite. Mistletoe will attach to their host tree or shrub and then extract water and nutrients from the host plant.

Bacteria-- Parts of a bacteria cell
A bacteria cell is classified as a prokaryotic cell because it does not have a nucleus or membrane-bound organelles.
A bacteria cell does have genetic material, but it is not organized in a nucleus.

What is a kite in Geometry?
A kite has four sides, therefore it is a Quadrilateral
One of the first things you may notice is that there are two pairs of different-length sides.
The perimeter of a kite is found by adding the length of all four sides.
You can find the area by using the diagonals of the kite. A kite has one diagonal that is longer than the other diagonal.

Learn the difference between physical and chemical changes by observing real life examples.
Is mentos and diet cke a physical or chemical change? Actually it is a phase change so it is a physical change.
I include other example like breaking a piggy bank, fireworks, cutting hair and several other examples. The goal is to help you undertand the difference between a physical and chemcal change by looking at examples.

Transparent material allows visible light to pass through it. Some of the light may be absorbed, but it is possible to see objects through the material.
Translucent materials allow some light through them but it is scattered so it is impossible to see a clear image through the material.
Opaque materials don't let light through them at all. The light is either reflected or absorbed.

In this video, I would like to talk about the cytoplasm of a cell.
The cytoplasm is a fluid found in cells and the organelles suspended within.
Cytoplasm is found in eukaryotic and prokaryotic cells.
The fluid of cytoplasm is called cytosol.
The organelles are found floating in this liquid.
Along with the cytoskeleton, the cytoplasm helps give the cell it’s shape.
Think of filling up a water balloon.
Without cytoplasm, the cell would be deflated and materials would not be able to pass easily from one organelle to another.
In addition, there are important molecules dissolved in the cytosol.
You will find enzymes, glucose, fatty acids, sugars, and amino acids that are used to keep the cell working. Waste products are also dissolved before they are taken in by vacuoles or sent out of the cell.
The cytoplasm is also the site of ATP production through the process of glycolysis when glucose is converted into pyruvate and 2 ATP’s are generated.
In addition, the enzymes found in the cytosol help break down larger molecules.
So there you go, the very important fluid of living cells, the cytoplasm.

Sublimation and Deposition are two types of phase changes. Sublimation is when a solid goes to a liquid and deposition is when a gas goes straight to a solid.
Sublimation and Deposition are phase changes. Sublimation is an endothermic process and deposition is an exothermic process.

Types of Proteins and their function in the human body
Proteins are made up of hundreds or thousands of smaller units called amino acids, which are attached to one another in long chains. Proteins are put together at ribosomes from a blueprint stored in DNA and more specifically from sections of the DNA called genes. There are 20 different types of amino acids that can be combined to make a protein. The order of amino acids determines each protein’s unique shape and its specific function or job.

Let’s take a look at 5 important functions of proteins
Messenger Proteins.
Enzymatic Proteins
Structural Proteins
