Mitosis


What is Mitosis? Mitosis is cell division. It is where a single cell divides into two equal cells called daughter cells.
  • One cell divides once into two daughter cells
  • Main purpose is to replace worn out or bad cells.
  • Mistakes made during Mitosis can lead to changes in DNA, which can cause genetic disorders.
5 different phases of Mitosis
  • Interphase
  • Prophase
  • Metaphase
  • Anaphase 
  • Telophase
Summary: The purpose of mitosis is for the an old or worn out cell to break down into 2 equal daughter cells that each get a full set of DNA or genetic code. It only happens one time for each cell. But a problem can occur if the body take to long during mitosis If it takes too long, the cells can change their DNA which can cause genetic disorders.

Meiosis




What is Meiosis?

Meiosis is cell division. The nucleus divides into 4 nuclei each having half the amount of chromosomes. Meiosis is essential in sexual reproduction an happens in all eukaryotes including single celled organisms.

-Cell division
-Four cells are created with half the chromosomes
-only happens with reproduction

Plant Cell vs Animal Cell




("Differences Between Plant And Animal Cells") 



Plant Cell - Larger than Animal Cells and have Chloroplasts, the cell wall, vacuoles. They need to perform photosynthesis to help the plants reproduce.  


Animal Cell - Animal cells do not need to carry on life through photosynthesis and have other parts of the cell to rely on. 

Similarities - The plant and animal cells are very similar because they are both eukaryotic cells. They both contain membrane-bound organelles. 



The cells are used to function off life and are needed to help each other and to help the plant or organism grow and produce. They are in every living thing and are much more important than we think. It is one of the building blocks of life. The cell function regulates the cell and holds everything together and keeps the parts of a cell functioning correctly.

Grace Moore 
Scientific Method - a method of research in which a problem is identified, relevant data are gathered, a hypothesis is formulated from this data, and the hypothesis is empirically tested.
Steps 
- Ask a question
-  Do background research
-  Construct a hypothesis
-  Test your hypothesis by doing an experiment
-  Analyze the data and results then draw a conclusion

Something surprising about this is that we do this almost every day. When you have a question and you are trying to solve it you do these steps in your head to try and to come to a conclusion. I learned this because when learning what this was and applying it in real-world situations it just brings to light that we do this with most questions that we have. When going into this I already knew some of the steps but I did not realize how often this can be used every day.

Symbiotic Relationships: Parasitism

Image result for parasitism








Parasitism:

-What is it? It's a symbiotic relationship where an organism lives in/on another organism called the host, and this organism harms the host.

The parasite's goal is to live in the other organism as long as they can without killing it, if the host is dead, the parasite will end up dying too.
There are many examples of parasitism everywhere, a simple example is a tick and a dog, the tick attaches to the dog and sucks the dog's blood, so the tick benefits from the dog, while the dog can be harmed by transmission of many diseases.

This symbiotic relationship differs from the predator-prey relationship, in parasitism, the goal is not to kill the host, and they can last for days, weeks, months, and even years, but in the predator-prey relationship one organism kills another organism in order to survive, that's the biggest difference.

Acid Rain -Cadence Amaral

What is acid rain?
  • Rain that's made acidic by pollution that causes environmental harm, usually to forests and lakes.


Why is it bad?
  • Acid rain makes waters acidic and causes them to absorb the pollution that makes its way from soil into lakes and streams.


What are the causes?
  • Acid rain is caused by a chemical reaction that starts when compounds like sulfur dioxide and nitrogen oxides are released into the air. 
  • An example of a cause for acid rain would be burning coal and other fossil fuels.


How can we prevent acid rain?
  • A good way to reduce acid rain is to produce energy without using fossil fuels. Instead, people can use renewable energy sources, such as solar and wind power.
Summary
  • In conclusion, Acid rain is acidic rain caused by the burning of coal and other fossil fuels. Acid rain causes the deconstruction of the environment and the poisoning of the earth with pollution. Acid rain is easily avoidable by using renewable energy sources, like solar and wind energy.

Biogenesis is where anything comes from how they were made and being born.
-reproduction
-life
-people used to think that if you put bread in a corner and left it there mice would just appear there and start eating it instead of coming from outside getting in and eating it.

I was not aware that people a few hundred years ago thought that animals just randomly appeared if there was food somewhere instead of reproduction happening them growing up and finding there way to food. If someone said that now they would sound dumb.
