Apologia Biology: Penicillin

If Alexander Fleming and his acquaintances had tested penicillin on guinea pigs instead of mice, we might not have this antibiotic today.  Penicillin is toxic to guinea pigs; it can cause diarrhea and even death if there are too much gram-positive bacteria in the guinea pig.  This antibiotic, however, is not toxic to humans and most animals, but is to very few.


The antibiotic, penicillin, comes in many forms, all are used to help heal infections.


Penicillin was not well known until November 19, 1999 at Alexander Fleming's Laboratory Museum in London.  The antibiotic was discovered in the 1940s, and is one of the best moves in therapeutic medicines.


Penicillins are used to fight against multiple infections in the body.  Yet, many bacteria don't react to penicillin.

Apologia Biology: How are Infectious Disease Microbes Transmitted?

How are infectious disease microbes transmitted? 

A.  Well, if a person has a disease and drinks a cup of water and then another person drinks out of the same cup, that person would most likely get the same disease.  Why?  Because the person with the disease put saliva in the water and on the cup.  This spreads the disease.

B.  If a stray dog bites a person and that person breaks flesh, that person could get a disease from the dog's germs.

C.  If  person puts a pair of shoes on that belong to someone else who happens to have athlete's foot, that person would end up getting that disease.

D.  If a stray cat scratches a person and that person breaks flesh, the germs from the cat's claws could spread diseases to that person.

Apologia Biology: Fungi

Fungi:  They are multi-cellular organisms that come in many separate categories.  Fungi can't secrete their diet out of the terrain, so they feed on other organisms.  Fungi can cause diseases.

Apologia Biology: Protozoa

Protozoa:  They are single-celled parasites who thoroughly enjoy moisture and spread diseases through water a lot.  Additionally, these microbes are known as parasites; therefore, they feed off various populations, sometimes humans.  Some engender intestinal infections. 

Apologia Biology: Viruses

Viruses:  In order to reproduce and grow, viruses have to be associated with an active species.  The habitat of a particular parasite is commonly referenced as your average host.  They can make our bodies very ill if they enter, but there are treatments for these viruses.

Apologia Biology: Bacteria

Bacteria:  They are single-celled, very small creatures who obtain their food from where they live, sometimes meaning the anatomy of a homo sapien in order to survive.  Reproduction can take place in the interior or on the exterior of the homo sapien.  Some bacteria inside the body can cause infections.  Conversely, there are also some beneficial bacteria.  These bacteria live in our intestines and put to work the nutrients we eat and the remains will be made into waste.  Also, scientists use some bacteria for vaccines and medicines.

Apologia Biology: What is a Microbe?

What is a microbe? 

Answer:  A microbe is a single-celled creature that cannot be seen with the naked eye.  They tend to be good and very useful; they take a part in helping us eat and breathe.  Some, however, are the opposite making organisms quite sick.  One thing that is cool about microbes is that they are known to be the first organisms on earth.  There are four major kinds of microbes: bacteria, viruses, fungi, and protozoa.

mnmtacos back story!

Hello!  We thought it might be a good idea to give you guys a little more information on who we are and why we are here!  First off, mnmtacos is created by two people: Meg and Patrick.  We are in a homeschool co-op where we do science and this blog is a unit test our teacher wants us to do instead of taking an actual end-of-the-year test!  We hope that our explanations are straightforward and simple.  Also, that they help you to understand the topics a little bit better.    

Force and motion: module 10: what are Newton's three laws?

Newton's three laws of motion are the groundwork of physics.  Those three laws were finished in less than 18 months.  The first law, also known as inertia, states that an object's velocity will not switch unless acted on by an outside force.  The second law states when an object is maneuvered on by an outside force, the force is equivalent to the mass of the object times the resulting acceleration.  The third law states that "For every action, there is an equal and opposite reaction."

Force and motion: module 10: what is friction?

Friction is created when two surfaces meet.  An example would be when a person rolls a ball on the ground.  It will eventually stop because of the friction between the two surfaces.

Force and motion: module 10: what is force?

A force is basically a push or a pull applied on an object in an attempt to switch that object's acceleration.  An example would be let's say two people were traveling in a car.  The car just so happens to run out of gas on them.  One of the two has to push the car to the nearest gas station.  The person pushing the car is using force.





Equation:  f= mass x acceleration


                 m= force/acceleration
          
                 a= force/mass

Force and motion: module 9: what is free fall?

Free fall is the case of an object that is falling facing the earth with nothing forbidding its fall.  An example would be like falling without air resistance.

Force and motion: module 10: what is momentum?

Momentum is the amount of motion of a moving object.  An example would be a train going 2,000 m/h has a very large amount of momentum.

Equation:  mass x velocity

Force and motion: module 9: what is acceleration?

Acceleration is a sudden change in an object's velocity.  An example would be a horse galloping at a velocity of 45 m/h west then quickly switched to 55 m/h north.

Equation: final velocity - initial velocity/time

Force and motion: module 9: what is speed?

Speed is how fast an object is moving.  An example would be a car going 43 m/h.

Equation:  distance/time

Force and motion: module 9: what is velocity?

Velocity is speed with direction; an example would be a train going north at 65 m/h.

Equation: distance/time north

Force and motion: module 10: what is inertia?

Inertia is Newton's first law.  It states that if an object is going a certain velocity, it will not change unless an outside force forces it to change.  An example would be if a bike is laying on the ground, and a little girl stands up the bike and starts riding away.  The velocity of the bike changed by an outside force.

Apologia force and motion: introduction

If you're using Exploring Creation with Physical Science by Dr. Jay L. Wile and reading module 9-11, you should read our blog!  In our blog we will be focusing on: inertia, velocity, speed, acceleration, momentum, free fall, force, friction, and Newton's laws.
