n atom “likes” to obtain a full outer shell. The fourth shell (in the atoms that we are studying today) can hold a maximum of 8 electrons. Think: Energetically, would the atom above “prefer” to give away its valence electrons or borrow some from another atom in order to fill its outer shell? Explain your reasoning
It depends on how many electrons are already in the outer shell.
If it is a large amount (if it is almost to the maximum), then it will want to borrow from another atom.
But if it is close to empty then it will want to give away so it will go back to the inner ring with will be full.
Hope this helps, good luck!

Describe two ways the material in this lesson illustrates the importance of creativity in scientific investigation
Answer:
Dalton used creativity to modify Proust's experiment and interpret the results. Millikan used creativity to develop a way to measure the charge on an electron. Thomson used creativity to interpret the results of the cathode ray tube experiment.
Explanation:
Creativity enables scientists to devise new ways of solving old problems.
I do not know what your material contains, however, creativity is key in scientific investigation. The term "science" is coined from the Latin word "scientia" which means knowledge.
In science, we endeavor to create new knowledge through research and innovation. This requires that a scientist must think of new and efficient ways of solving old problems. This underscores the centrality of creativity in scientific investigation.

Cell membranes are primarily made of a component that contains fatty acids. This component is most likely a. Carbohydrate. Protein. Nucleic acid Lipid
Answer:
Lipid
Explanation:
I just took the test and I got it right
Cell membranes are primarily made of fatty acids which are the components of lipids. Thus, the correct option is D.
What is a Cell membrane?A cell membrane may be defined as a biological membrane that separates the interior of the cell with respect to the outer environment. It provides overall protection to the cell from external damage.
The Cell membrane is made up of a phospholipid bilayer. This bilayer is amphipathic in nature. The phosphate group forms a polar head while lipid forms a non-polar tail.
Due to undissolved in water, lipids deliver stability to the cell membrane against the water.
Therefore, Cell membranes are primarily made of fatty acids which are the components of lipids. Thus, the correct option is D.

How are P waves and S waves used to find out how far away an earthquake is
Answer:
The distance between the beginning of the first P wave and the first S wave tells you how many seconds the waves are apart.
Explanation:
This number will be used to tell you how far your seismograph is from the epicenter of the earthquake.
Answer:
The distance between the beginning of the first P wave and the first S wave tells you how many seconds the waves are apart.
Explanation:
This number will be used to tell you how far your seismograph (an instrument that measures and records details of earthquakes, such as force and duration) is from the epicenter (the point on the earth's surface vertically above the focus of an earthquake) of the earthquake. Measure the distance between the first P wave and the first S wave.

Most elements' names end in the suffix -ium. This practice started around the year 1800, with many elements discovered before that having a more common name. However, some elements are more recently discovered and don't end in -ium. Do you notice any patterns for these elements?
Answer:
The last naturally occurring element to be discovered was francium (87) in 1939. Since that discovery, plutonium (94), neptunium (93) and astatine (85), which were initially created in the lab in 1940, have since been found in nature.
Explanation:
The -ium suffix is just a Latin suffix that creates abstract nouns, therefore, it's being used to construct scientific component names from their nomenclature origin, including such minerals (calcium from calx) or person names (gadolinium), and further discussion can be defined as follows:
This denotes a metallic element including platinum or barium. It's a group that forms positively charged ions: ammonia chloride, hydronium ion. It indicates a cellular structure, syncytium Etymology, New Latin, via Latin, via Greek -ion, small suffix.Its last found natural element found is francium (87) in 1939. Ever since, plutonium (94), neptunium (93), and astatine (85), which were synthesized inside the lab in 1940, have indeed been discovered throughout nature.Learn more:

What are the two laws of conservation of energy?
Answer:
Explanation:
The law of conservation of energy states that energy can neither be created nor destroyed - only converted from one form of energy to another. This means that a system always has the same amount of energy, unless it's added from the outside. This is particularly confusing in the case of non-conservative forces, where energy is converted from mechanical energy into thermal energy, but the overall energy does remain the same. The only way to use energy is to transform energy from one form to another.
Answer:
The first law, also known as Law of Conservation of Energy, states that energy cannot be created or destroyed in an isolated system. The second law of thermodynamics states that the entropy of any isolated system always increases.

According to law of conservation of matter , the mass of the trees got converted fro one form of matter to another.
What is law of conservation of matter?According to law of conservation of matter, it is evident that matter is neither created nor destroyed rather it is restored at the end of a chemical reaction .
Law of conservation of mass and energy are related as mass and energy are directly proportional which is indicated by the equation E=mc².Concept of conservation of mass is widely used in field of chemistry, fluid dynamics.
Law needs to be modified in accordance with laws of quantum mechanics under the principle of mass and energy equivalence.This law was proposed by Antoine Lavoisier in the year 1789.
