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.

Cell membranes are primarily made of a component that contains fatty acids. This component is most likely a. Carbohydrate. Protein. Nucleic acid Lipid

Answers

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.

Before the fire, the forest consists of large trees. After the fire, there is only ash. Explain what the law of conservation of matter suggests happened to the rest of the mass of the trees.

Answers

Matter can’t be created or destroyed, so the mass of the trees broke down and separated across the forest in the form of ash.

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.

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?

Answers

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.

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

Answers

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!

True or False When nitrogen enters a chemical reaction it is looking for three neutrons.

Answers

Answer:

False

Explanation:

Every chemical element undergoes a reaction in order to fulfill the completion of their outermost shell. This is the case of nitrogen (symbol "N"), which is an element found in group 5 of the periodic table with atomic number 7 (i.e. 1s2 2s2 2p3). It possesses three valence electrons in it's outermost shell.

Looking at the configuration of the Nitrogen atom, it requires three electrons to complete its electron shell. Hence, nitrogen will enter a reaction in order to have its need for THREE ELECTRONS met in order to have its electron shell full.

Note that, nitrogen enters a chemical reaction to look for three electrons not three neutrons.
