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?

ddd [48]

Answer:

An increase in the population of a species increases the chances of survival for that species. The species will be able to survive severe changes such as diseases and disasters.

Which of the following elements would be more reactive with other elements
kirza4 [7]

Answer:

The chemical element which would be the most reactive with other elements is: D. helium, #2.

A chemical property is a property of a chemical substance that is observable and measurable in the course of a chemical reaction. The chemical properties of a chemical substance include the following:

  • Tarnishing.
  • Heat of combustion.
  • Flammability.
  • Acidity.
  • Chemical reactivity.

Chemical reactivity is a property that determines how readily a chemical element would bond with other chemical elements to form a new compound.

Basically, the ability of a chemical element to bond with other chemical elements is highly dependent on the number of valence electrons.

The chemical elements Neon and Argon are noble elements, and as such have a filled outermost shell and wouldn't react with other chemical elements.

Helium has a single valence electron in its outermost shell while Boron has three (3) valence electrons in its outermost shell.

In conclusion, Helium with an atomic number of two (2) would be the most reactive with other elements.
