water has an unusually high heat of vaporization (-40+kj/mol), allowing it to be used for evaporative cooling. what do you think would happen if a different compound was used for evaporative cooling - for example, methane (-8kj/mol)
Answer:
A lesser amount of heat will be drawn up from the mass to be cooled per unit mole of the new liquid vaporized, compared to the amount of heat that will be drawn by vaporizing a unit mole of water. For the case of methane, five mole of methane needs to be vaporized to get the same cooling effect of a mole of water.
Explanation:
For a liquid like water to vaporize, it must draw a certain amount of energy from the surrounding in order for some of its molecules to gain enough energy to break out of the surface of the liquid as gas. If the heat of vaporization of water is about -40 kJ/mol, it means that for a mole of water to change from liquid to gas, it must draw up 40 kJ worth of heat from its surrounding. The effect is that the surrounding mass losses 40 kJ worth of heat, and cools down. If we should now use a new liquid, say methane with heat of vaporization of about -8kJ/mol, five moles of methane needs to be vaporized to get the same cooling effect of vaporizing a mole of water; since the heat that will be drawn by a mole of the methane is just bout 8 kJ.
When defining a medical term, one usually begins the defintion with the definition of the:_________
Answer: Suffix
When defining a medical term, one begin the definition with the definition of SUFFIX.
Explanation:
Suffix refers to words added to the end of words to add meaning to the words or change the word functions.
When defining a medical term, one begin the definition with the definition of SUFFIX or you define at the end because the suffix of medical terms signifies procedures, diseases, conditions which is added to prefix( word that begin) which signify the meaning of term and give anatomical location or function.

1. Give two other names for AB.
2. Name three points that are collinear.
3. Give another name for plane F.
4. Name a point that is not coplanar with A, B, and C.
5. Give another name for CD.
6. Name three rays with endpoint B.
7. Name a pair of opposite rays.
8. Give another name for CD.
Problem 1
Two other names for line AB are
Line BALine hThe order of the letters doesn't matter which is why AB is the same as BA. Line h is another name since the h is attached to the line.
======================================
Problem 2
Three points that are collinear are: C, B, and D
Those three points all fall along the same vertical line (line g)
=====================================
Problem 3
Pick any three points you want in plane F as long as those points do not fall on the same line. The only three points we can pick are A, B and E. Those points are not all on the same line. They uniquely define plane F. So we can say "plane ABE" in place of "plane F". In this case, the order of the lettering does not matter.
======================================
Problem 4
Point E is not coplanar with A, B and C. Plane ABC is a vertical wall (of sorts) while point E is on the floor (plane F) away from the wall ABC. In contrast, a point like D is on plane ABC because line g goes through this plane as well.
=======================================
Problem 5
Line CD can be written as
line CBline BCline DCline BDany of those are valid. All we need are two points that are on line CD. The order doesn't matter.
=======================================
Problem 6
Start with point B. Then add on a letter that forms a ray or half a line. We could write
ray BCray BAray BDWe cannot write ray BE since there is no line connecting the two points. Also, when it comes to naming rays, the order does matter. The first point is where we start and the second point is where the ray aims and goes on forever toward. Something like ray BC is not the same as ray CB (since the endpoint here is C instead of B).
=======================================
Problem 7
One pair of opposite rays is BC and BD. They point in completely different directions and both fall on along the same straight line extended out infinitely in both directions. Put another way: gluing together the endpoints of opposite rays forms a line.
=======================================
Problem 8
This seems to be a repeat of problem 5. I'm not sure if this is a typo or not.
Fish breathe underwater through gills that remove dissolved oxygen from the water. What phenomenon allows oxygen to dissolve in water
Answer:
The correct answer is "aeration".
Explanation:
Fish depend on the presence of dissolved oxygen in the water to breathe, because they take oxygen from water in a mechanism known as countercurrent exchange. Oxygen gets dissolved in water when winds stirs it in a phenomenon known as aeration. Aeration brings water and oxygen in direct contact, and not only is responsible of producing dissolved oxygen in water, but also increases its palpability by removing its flat taste.
Which of the following is not a true statement regarding the genetic code?
A. The genetic code is nearly universal, with only a few minor exceptions.
B. The genetic code is nonoverlapping.
C. The genetic code is degenerate.
D. The genetic code is triplet-based.
E. Each codon represents a different amino acid.
Answer:
E. Each codon represents a different amino acid.
Explanation:
The genetic code refers to the set of rules guiding the translation of nucleotide bases in DNA or RNA into an amino acid sequence (proteins). The genetic code contains all the codons in the genome, which is a group of three nucleotide base (triplet-based). Each codon species a particular amino acid, however, more than one codon can code for a particular amino acid. This characteristics of the genetic code is called DEGENERACY.
The genetic code is said to be nearly universal because the same codon encodes the same amino acid in almost all living organisms with only few exceptions. The nonoverlapping nature of the genetic code refers to the fact the three bases of a codon are read independently from the bases of another codon i.e. codons do not overlap.
A codon represents one amino acid but more than one codon can represent the same amino acid. Hence, option E is untrue

In _____________ selection, individuals with both extreme forms of a trait are at a selective advantage.
Answer:
disruptive/diversifying selection
Explanation:
Disruptive (also known as diversifying) selection is a type of natural selection where extreme phenotypic values are more favored rather than intermediate phenotypes. The disruptive selection favors the survivance and reproduction of organisms with extreme phenotypic traits, and in turn impairs the reproduction of organisms with intermediate traits, thereby changing the allele frequencies in the population in order to favor extreme values. An example of disruptive selection is the beak size of Galapagos finches, where extreme phenotypes of this trait have shown to be adaptive according to the type of food found in each island.

Transport proteins play a role in both?
Answer:
Transport proteins play a role in both active and passive transport to move molecules across the plasma membrane
Transport proteins play a role in both passive and active transport. Therefore, option A is correct.
Cell transport means the transportation of a molecule or substance across a plasma membrane. The molecule has the ability to enter or exit the cell. The plasma membrane and cell membrane are both permeable to different substances like ions and water molecule.
Active Transport is the movement of molecules from lower concentration to a region of higher concentration against a gradient with the use of energy.
Passive transport is the movement of ions and other molecular substances across membrane along the concentration gradient, without any need of energy.
Exocytosis, endocytosis (movement of molecule in and out of cell) and vesicle transport(transport of vesicles inside of cell) do not require transport protein.
Phagocytosis is a type of endocytosis that is involved in engulfment of substance or damaged cell.
Therefore, option A is correct.

If a mutation in DNA caused a new amino acid sequence to occur, what might happen to the subsequent protein?
The amino acids contain R groups that interact with each other creating a three - dimensional structure. This higher - order structure decides the biological activity of that protein. if the wrong amino acid joins the polypeptide chain the higher - order structure will change, effecting the functioning of the protein.This will lead to many diseases such as sickle cell anemia is most common.
