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.

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

2Cu+S→Cu2S
Copper (Cu) reacts with sulfur (S) to form copper sulfide as shown in the chemical equation. A scientist adds 4 grams of Cu to 2 grams of S to start the reaction. At the end of the experiment, she has 6 grams of product. In one to two sentences, explain what would happen if the scientist increased the amount of copper to 6 grams, and why
The result of the reaction when the scientist is added more copper then the amount of product increases. If copper is increased to 6 g then the product copper sulphide increases to 9 g.
What is copper sulphide?Copper sulphide is a compound made by metallic copper and sulfur gas. As per the reaction, two moles of copper is required to react completely with one mole of sulfur. Thus copper is the limiting reactant here.
It is the limiting reactant in a reaction that decide the final yield of the product. It is given that, 4 g of copper produced 6 g of the product then, the mass of product produced by 6 grams of copper is calculates as follows:
mass of product = (6×6)/4 =9 g
Hence, if the amount of copper is increased to 6 g, the product increases to 9 g.

A balloon (approximate as a sphere) is inflated such that its
radius is 7.00 cm. What is the volume of air inside the balloon
in ML? (Volume of a sphere = Truse 3.14 for TT)
mL
Answer: 1436 mL
Explanation: 4/3 • 3.14 • 7^3 <— calculate
Volume is the measurement of the shapes that are given by the dimensions like the radius. A balloon in the shape of a sphere with a radius of 7.00 cm is 1436.76 cm³.
What is the volume of the sphere?The volume is the quantitative measure of the object or substance with respect to its radius or diameter which is given in milliliters, liters, or cubic centimeters.
The volume has no definitive shape but acquires that of the container like the spherical shape of the balloon.
The formula to calculate the volume of a sphere is,
[tex]\rm V = \dfrac{4}{3} \pi r ^{3}[/tex]
Given,
Radius (r) of the balloon = 7.00 cm
π = 3.14
Substituting values of r in the above formula as:
[tex]\begin{aligned} \rm V &= \dfrac{4}{3} \pi \rm r ^{3}\\\\\rm V &= \dfrac{4}{3} (3.14) (7^{3})\\\\\rm V &= 1436.76 \rm \;cm^{3}\end{aligned}[/tex]
Therefore, a balloon with a 7.0 cm radius has a volume of 1436.76 cm³.

Which of the following best describes Galileo’s conclusion about how weight affects gravity? A No matter the weight of an object, gravity remains constant. B Heavier objects will increase the value of gravity. C Objects that are the same weight as a cannonball have zero gravity. D With any two similar sized objects, one will have double the gravity of the other.
Answer: a
Explanation:
according to the passage: “galileo concluded that gravity is a constant based on the experiment result: weight doesn’t change the speed at which object fall
Galileo’s conclusion about how weight affects gravity that heavier objects will increase the value of gravity. option B is correct.
What is gravity?Gravity is a force of attraction that holds the planets in orbit around the sun and the moon in orbit around Earth. Gravity not only pulls on mass of any object but also on light from any coming source.
And according to the Newton sir law also if the mass of any object is more or double then the gravity will also become double from the expected gravity.
Therefore, Galileo’s conclusion about how weight affects gravity that heavier objects will increase the value of gravity. option B is correct.

9. How long in minutes does it take sunlight to reach earth if the sun is 5,000,000 km from earth? (speed of light = 300,000 km/s)
Answer:
Sunlight travels at the speed of light. Photons emitted from the surface of the Sun need to travel across the vacuum of space to reach our eyes.
The short answer is that it takes sunlight an average of 8 minutes and 20 seconds to travel from the Sun to the Earth.
If the Sun suddenly disappeared from the Universe (not that this could actually happen, don’t panic), it would take a little more than 8 minutes before you realized it was time to put on a sweater.

How many elements are in the periodic table?
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!
