Daily Science Fact-Would kissing this frog kill you?



Maybe, but at least it would be very painful. This is a Black-legged Dart Frog This frog  gets it name from having dark legs.  Only a tiny portion if it’s poison can cause fevers, excruciating pain, seizures and, possibly, death by respiratory and muscular paralysis.

Proteins-A beginners guide





What is a protein?Proteins are essential for your cells and body. These are over 100 types of proteins but what is a protein?



Proteins are long strands of amino acids

There are 20 types of amino acids to create proteins

DNA is transcribed into an RNA transcript and the ribosomes uses this to create the correct order of the amino acids.



What are some of the jobs of proteins?

Some proteins like collagen are used as building blocks and structural support for hair, nails,skins, ligaments and tendons



Enzymes some proteins are enzymes which help speed up chemical reactions.



Digestion Pepsin is used in your stomach to help with digestion



Some proteins move molecules from one place to another. Hemoglobin found in blood helps transport oxygen in the body.



Proteins help in muscle contraction. The protein actin and myosin are both involved in muscle contraction and movement.



Some proteins regulate body functions. The protein insulin regulates glucose metabolism by controlling the blood-sugar concentration.



Antibodies are proteins produced by the immune system to help remove foreign substances and fight infections.



As you can see the proteins produced at the ribosomes help the cell and body stay alive and function properly.

Ribosomes The Protein Factories





What are ribosomes.

Ribosomes are small protein factories found in cells.

They are located in the cytoplasm and on the ER

See the small dots on the ER and in the cytoplasm



Here is how the ribosome makes a protein.

In the cytoplasm DNA is transcribed to RNA

The ribosome reads the RNA in triplets and the correct amino acids are put together to create a protein.

Ribosomes are found in plant,animal, and bacterial cells.

Cytoplasm-Cell Organelles





Cytoplasm is referred as cytosol,

It is a clear,jelly like substance. It is a little thicker than an egg white.



Think of cytoplasm as the water in the pool



A pool does not function well without the water filling it up.

The organelles are suspended in the cytoplasm much like these floats are in the next video.



Cytoplasm is located between the nucleus and the cell membrane



The cytoskeleton present in the cytoplasm gives the cell its shape. The cytoplasm also has nutrients salts and it aids to dissolve waste products.

It helps movement of the cellular materials around the cell through a process called cytoplasmic streaming. Here is an example of cytoplasmic streaming Notice how the chloroplasts moving in the euglena cells.



In summary, the cytoplasm is a clear, jelly like substance found in cells that contains nutrients,salts,

Helps give the cell it’s shape, and helps cell materials move about.

Amazing Science Facts





Which three elements make up all carbohydrates?

All carbohydrates are made of oxygen,carbon,and hydrogen.

All those yummy sugars are made up of these three elements.

What is the most abundant protein in our hair?

Our hair is composed mainly of the protein keratin.

In fact keratin makes up 60 to 85 % of our hair.

Lately scientists have begun understand you can use this protein to identify people

What is the most abundant protein in our body?

Collagen is the most abundant protein in our body. It is used in our skin,ligaments, and tendons.

It is found in all animals.

Do all fish have scales. No In fact the hagfish has a slimy mucus covering it's body and no scales.

The lamprey has a skin like covering.

What is the largest living structure in the world?

The great barrier reef off the coast of Austria is the largest living structure. It is composed of small polyps.

It has been in the news lately because it is beginning to die off.

Have aliens visited earth?

No this is just a picture of a dust mite magnified using an electron microscope.

An electron microscope uses electronsto magnify, and can magnify up to 2 million times.

What is this insect trying to say to you

It is saying, " with it's yellow or warning coloration it is saying to stay way or I will bite,sting, or harm you if you come to close."
