1. Develop a timeline in which you predict 10 of the most important advances that may occur in science during the next century.

Don't forget to add dates to your timeline!
2. Give an example of a living organism and how this organism meets at least six characteristics of life. You must be very specific for your organism in your descriptions to demonstrate your understanding of the characteristics of life. For example, you cannot just say "a dog obtains energy by eating." You need to explain what kinds of food a dog eats, what type of consumer it is, etc.
3. The four main groups of macromolecules are important to our bodies for various reasons. Explain the functions of each of these groups of compounds in your body.
4. There have been major developmental milestones in Earth’s history as well as mass extinction events. Do a little research on an organism that has gone extinct because of human impact. Answer the following questions:
What is the organism?
Where was it found?
What caused it to become extinct?

Why does the angle at which the Sun’s rays hit the Earth change during the year, and how does this cause the seasons to differ i
kirill115 [55]

Explanation:

This is due to the tilted earth's axis. During the summer, the sun's beams hit the Earth at a steep angle. The light does not spread out so a lot, subsequently expanding the measure of energy hitting any given spot. Likewise, the long daylight hours permit the Earth plenty of time to reach warm temperatures.

What is cancer? (please make sure to include mitosis and cell division)
saw5 [17]

Answer:

<h2><em>Cancer is a disease in which abnormal cells divide uncontrollably and destroy the body tissue. // Putting it into simple words, It’s an error caused in meiosis and cell division.</em></h2><h2 />

WELL here's what it does to your body... (please read all of it...thank u)  

Let's start with what is cancer? Cancer is an uncontrolled growth of abnormal cells in the body. Cancer is caused by a mutation in DNA cells. The DNA inside a cell is packed into a large number of individual genes. Those genes in the cell, each contains a set of instructions telling the cells what types of functions to perform as well as how to grow and divide into more cells. Kind of like a little increased cell factory like system. Errors in the 'instructions' can cause the cell to stop its normal work and functionality and allow a cell to become cancerous.  

Soo... gene mutations can instruct healthy cells to allow and naturalize excessive growth or rapid growth in cells to divide. So then all the new cells are infected and mutated. It can also fail to stop unhealthy rapid growth. Basically, cancer cells lose control in the factory and basically keep on spreading and growing an unhealthy amount till it gets deadly. Just kidding but basically thats what it means. AND gene mutations also make "mistakes" when they try to fix DNA errors. Which then are lead to turn into cancerous cells.  

Now, what causes gene mutation? Gene mutation can be caused by one of many reasons. Two of the main reasons is being born fresh out your mommas womb. You could be born with a genetic gene mutation you most likely inherited from your parents. OR it could be caused by the enviroment you live in. Causes such as smoking, radiation, obesity, harmones, etc. and a lack of exercise.  However, cells contain a mechanism that recognizes when a mistake occurs and repairs the mistake. But occasionally, a mistake is missed... which therefore results in a cell becoming cancerous.

MEANING:

Cancer is bad for your body. periodt.
