35-18 = 17 protons = <u>17 electrons</u>
Answer:
d making models.
Explanation:
When scientists create a representation of a complex process, they are inferring that they are making models.
A model is an abstraction of the real world or a complex process. Models are very useful in developing solutions to processes that are not easily simplified.
- The models allow a part of a body to be simply studied.
- Through this simple abstraction, extrapolations to other parts of the system can be deduced.
- This can give very useful insights into the other parts of the system.
- The heterogeneity of complex processes is a huge limitation to understanding them.
- A homogenous part can be modelled and used to understand the system.
We wouldn't have the majority of the people around that we do now, soldiers would have bleed out on the field, people needing blood transplants due o having cancer, people in car accidents, people with brain bleeds. The population would practically be cut in half.
The different atmospheric pressures cause the air to have zones with different temperatures, the cold air tends to descend and the hot air to rise because it has less density. This movement of the two airs in the atmosphere is what generates the wind.
Answer:
29. Proteins support the body's structural framework, chemical reactions, and contractions (muscle movement).
30. Proteins have a primary structure (polypeptide chain of amino acids), secondary structure (made up of alpha helices and beta pleat sheets), tertiary structure (superimposed on secondary structure), and quaternary structure (2 or more polypeptide chains with its own tertiary structure).
31. Protein molecules can denature if conditions aren't right, such as the wrong temperature or pH level. When denatured, proteins typically lose their shape and their function for a short time because their active sites become deactivated (though if conditions are too extreme, they can permanently lose their function). This happens to globular proteins because they are not nearly as stable as fibrous proteins due to their functional 3D shape.
I just did the first 3 since I could easily access the proteins section in my textbook at the moment. :)
