What is blood made of?

Sunday, February 17, 2019


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
.
It has many important functions
Here is a list of some of the major jobs
Transports oxygen to each cell and
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.

If you place blood in a centrifuge and spun it around
Here is how it would separate out

44 % would be red blood cells also called erythrocytes
1 % would be white blood cells and platelets
55% plasma

Red blood cells contain a protein called hemoglobin that carries oxygen. Red blood cells also remove carbon dioxide from your body, transporting it to the lungs for you to exhale.

Red blood cells are made inside your bones, in the bone marrow. They typically live for about 120 days, and then they die.


White blood cells (WBCs), also called leukocytes, are an important part of the immune system. These cells help fight infections by attacking bacteria, viruses, and germs that invade the body. White blood cells originate in the bone marrow but circulate throughout the bloodstream. There are five major types of white blood cells

Plasma
Is the liquid portion of the blood.
It is 90 % water but contains other very important ingredients such as
glucose, electrolytes such as calcium, sodium, potassium, phosphate
hormones and waste products.

Platelets are tiny blood cells that help your body form clots to stop bleeding. Without these platelets, a minor cut could result in you losing all of your blood.

There are 8 different types of blood
A positive or negative
B positive or negative
AB positive or negative
O positive or negative

Prime Factorization of 164 and 500

Friday, February 15, 2019




Prime factorization of 164 and 500.

Prime factorization which is also called integer factorization or prime decomposition involves finding which numbers multiply together to equal the original number. In this video, I use a factor tree to find the prime factors of one hundred and sixty-four and five hundred.

In this video, I will express as a product of its prime numbers for 164 and 500.

Integer factorization of 164  2 * 2 * 41
Integers factorization of 500 2 * 2 * 5 * 5 * 5

Prime decomposition of 164  2 * 2 * 41

Solvent Solute Solution What is the difference?

Wednesday, February 13, 2019




Learn the difference between solvent and solute.

Solvent is the object that dissolves the solute.

Imagine you have water, tea leaves, and sugar.

The water is the solvent, the tea leaves and sugar would be your solute.


Different types of Fossils

Tuesday, February 12, 2019



How do we know that the tyrannosaurus rex once roamed the earth?
How do we study a mosquito that is 46 million years old?
The answer is fossils. Fossils are the remains of once-living organisms.
Let’s take a look at five different types of fossils.

Up first, mineralization.  Mineralization occurs when an organism dies and is buried under sand and other sediments. The minerals in the water begin to replace the organisms original material. The object may harden and almost become a rock. For example, petrified wood is an example of mineralization.

Carbonization occurs when an organism dies and is compressed over time and eventually all that
remains is a carbon outline of the original organism. 

Molds and Casts 
Sometimes an organism will die and you may have a bone or a tooth and it will make an impression and then this impression hardens so you have a permanent record of the tooth or bone. On the other hand, this impression can then fill up and create a caste which is a copy of the impression. 

Trace Fossils

Sometimes you don't even have a record of the original organism but you have evidence of their behavior. You may find a footprint or tracks This type of a fossil is called a trace fossil.

Finally, you get a copy of the original material. What may happen is you may have a tiger that falls in a tar pit and is preserved for thousands of years. An insect may fall into amber and it will remain in this amber for a very long time.

There you go five different types of fossils which are remains of once-living organisms.

Prime factorization and Factor Trees for 36 and 69

Thursday, January 24, 2019


Prime factorization of 36 and 69
Prime factorization which is also called integer factorization or prime decomposition involves finding which numbers multiply together to equal the original number. In this video, I use a factor tree to find the prime factors of 36 and 69
In this video, I will express as a product of its prime numbers
Integer factorization of 36 = 2*2*3*3

2^2 * 3^2
Integers factorization of 69 = 3*23
Prime decomposition of 36 = = 2*2*3*3 2^2 * 3^2

Prime decomposition of 69 = 3*23
