Answer:
Glycolipid
Explanation:
These are called glycolipids.
Glyco comes from the carbohydrate, and is a word relating to sugars, which are a type of carbohydrate
Lipid is a fat/oil, and as you could have guessed, comes from the phospholipid.
Hope I helped! :)
A carbohydrate attached to a phospholipid is called a glycolipid.
What is a glycolipid?Glycolipids can be described as the complex type lipid containing carbohydrates, fatty acids, and glycerol groups. The glycosidic term is used for any molecule containing one or more monosaccharides bound by glycosidic linkage.
Glycolipids can be also called structural lipids, which are generally found in the extracellular face of the cell membranes. Different types of glycolipid are Cerebroside and ganglioside.
Glycolipids provide energy to cells and help to determine the blood group. The blood group types determine from the oligosaccharides attached to a particular glycolipid on the surface of blood cells.
It assists the immune system of the body by destroying the pathogens in the human body.
A phospholipid is a lipid that is attached to the phosphate group. When the carbohydrate molecules attached to the lipid are known as glycolipid. Glycolipid plays an important role on the cell to cell interaction and cell differentiation.

A mixture of neon and argon gases exerts a total pressure of 2.39 atm. The partial pressure of the neon alone is 1.84 atm, What is the partial pressure of the argon?
Answer:
0.55 atm
Explanation:
According to Dalton's law of partial pressures,
The total pressure is the summation of the partial pressures of individual gases in a sample of non-reactive gases.
Since Neon and Argon are noble gases, they do not react with each other. So we can apply Dalton's partial pressure law.
P total = P Ar + P Ne
2.39 atm = P Ar+ 1.84 atm
P Ar = 2.39 atm - 1.84 atm
= 0.55 atm
According to the Dalton's law of partial pressure the partial pressure of the argon is 0.55 atm.
What is pressure?Pressure is defined as the force applied on an object perpendicular to it's surface per unit area over which it is distributed.Gauge pressure is a pressure which is related with the ambient pressure.
There are various units by which pressure is expressed most of which are derived units which are obtained from unit of force divided by unit of area . The SI unit of pressure is pascal .
It is a scalar quantity which is related to the vector area element with a normal force acting on it.It is distributed over solid boundaries and across arbitary sections of fluid normal to the boundaries at every point.
In this case, pressure of gas argon is obtained by subtracting pressure of gas neon from the total pressure ,that is 2.39-1.84=0.55 atmosphere.
Thus ,the partial pressure of gas argon in atmosphere is 0.55 atmosphere.

Using two to three sentences, summarize what you investigated and observed in this lab. I investigated how chemical compounds work and what to use to put them together.
Why do you believe knowing how elements and compounds react together is essential in everyday matters? So, you can cook and stop injuries, these two things happen a lot in day-to-day life.
Some elements are more "reactive" than other elements; why do you think this is? Because certain elements in the compound may react more to fire or water and many other elements.
Choose one of the compounds from the table and explain how you know the numbers of atoms in your formula. Because if you add all the atoms, put in that’s the total amount. For example, water has one hydrogen atom and one oxygen atom, so water has two atoms.
Is it possible for two different compounds to be made from the exact same two elements? Why or why not? With a limited number of elements (less than 120 are known), does this mean we also have a small number of compounds, or do we have many compounds in this world? Yes, it is possible like water and hydrogen peroxide. The formula of water is H20 but hydrogen peroxide has one more oxygen-H202.

Relate how a household sponge and water can be used to model
the concept of an unsaturated solution, a saturated solution, and a supersaturated
solution.
The sponge is unsaturated when it is taking in more water. It becomes saturated when it stops taking in water. It is supersaturated when water starts oozing out from the sponge.
A saturated solution contains just as much solute as it normally hold at a particular temperature. An unsaturated solution contains less solute than it can normally hold at a particular temperature. A supersaturated solution contains more solute than it can normally hold at a particular temperature.
We can use a sponge to model these three scenario as follows;
Water continues to enter into the sponge when it is unsaturated, this continues until the sponge becomes saturated with water and takes in no more water. When the sponge becomes supersaturated, water begins to ooze out from the sponge because it can no longer hold more water.

In the fall, how does the high pressure area
affect the hurricane?
Answer:
Hurricanes occur when ocean water warms during the spring, summer and early fall.
Explanation:
Warm air just above the water’s surface rises. The rising warm air creates a reduction in pressure at the surface, what meteorologists call a low-pressure area. Because nearby air is at a higher pressure, it will flow into the low-pressure zone.

what is pyruvic acid changed into in lactic acid fermentation
Answer:
pyruvic acid changes to alcohol and carbon dioxide.
Explanation:
In lactic acid fermentation, pyruvic acid from glycolysis changes to lactic acid. This type of fermentation is carried out by the bacteria in yogurt, and by your own muscle cells.
I HOPE THIS HELPS!!!!!
Alcohol and carbon dioxide are produced when pyruvic acid is fermented. The chemical process in which molecules break down is called as fermentation.
What is fermentation ?Fermentation is an anaerobic chemical process that breaks down molecules like glucose. Pyruvic acid undergoes fermentation to produced lactic acid.
More specifically, fermentation is the foaming that happens during the creation of wine and beer, a procedure that has been around for at least 10,000 years.
Pyruvic acid produced during glycolysis transforms into lactic acid during lactic acid fermentation. Alcohol and carbon dioxide are produced when pyruvic acid is fermented.
Thus, the pyruvic acid when change into lactic acid fermentation obtained alcohol and carbon dioxide.

Which hybrid orbitals overlap to form the sigma bonds between the indicated atoms in xanthine?
Many nitrogen and carbon atoms can be found in the structure of a heterocyclic molecule called xanthine, which is present in many biological systems.
The development of a sigma bond between these atoms is an essential component of its binding. A special example is the sigma bond between the nitrogen atom and the neighboring carbon atom. In the context of this sigma bond, the hybridization state of nitrogen can be either [tex]\rm sp^2[/tex]or [tex]\rm sp^3[/tex], and the hybridization state of carbon can be [tex]\rm sp^3[/tex]. A sigma bond is formed when the hybrid orbitals of carbon and nitrogen, which are each [tex]\rm sp^2[/tex] hybridized and [tex]\rm sp^3[/tex] hybridized, overlap. A strong covalent bond can develop when the [tex]\rm sp^2[/tex] hybrid orbitals of nitrogen and carbon line up. This allows electron sharing.

NEED HELP ASAP! Write a statement explaining your claim about whether or not the equation is correctly balanced.
Then, provide evidence that supports your claim about whether or not the equation is correctly
balanced. Next, connect your evidence to your claim about the equation.
Answer:
I think that it it correctly balanced that is my opinion and, because the way it is set up, that the answer will tell you weather or not it is correctly balanced or not.
Evaluating the number of atoms of each element on the product and reactant side, we can conclude that the student's equation isn't balanced.
Given the chemical reaction :
[tex] Al_{4}C_{3} + 6H_{2}O ---> 3CH_{4} + 4Al(OH)_{3} [/tex]
For a balanced equation, the number of atoms of each element in the product side must be equal to that on the reactant side.
Number of hydrogen :
Reactant side = (6 × 2) = 12
Product side = (6 × 2) + (6 × 2) = 12 + 24 = 24
Product side ≠ reactant side ; Hence, the equation isn't balanced
The balanced equation for the reaction goes thus :
[tex] Al_{4}C_{3} + 12H_{2}O ---> 3CH_{4} + 4Al(OH)_{3} [/tex]
Reactant side :
Al = 4
H = (12 × 2) = 24
O = 12
C = 3
Product side :
H = (6 × 2) + (6 × 2) = 12 + 24 = 24
Al = 4
O = 4 × 3 = 12
C = 3
Therefore, the student's equation isn't balanced, the balanced version of the equation has been given .
