The results of the experiment performed in the passage, and the model proposed in response, suggest that what relationship exist

s between the surface activity of mutant proteins and the relaxation of wrinkles under compression in the protein film?
A. The surface activity of the monomers is decreased in each mutant protein, allowing release of the monomers from the interface.

B. Compression increases the attractive forces between water molecules and portions of Bs1A monomers, contributing to release of the monomers from the interface.

C. Wrinkle formation increases the surface activity in mutant proteins, causing release of the monomers from the interface.

D. Decreased surface activity of mutant protein leads to compression in the protein film, causing release of monomers from the interface.

The surface activity of the monomers is decreased in each mutant protein, allowing release of the monomers from the interface.

Explanation:

Compression of the film is a consequence of withdrawal of protein solution from the droplet during step 2 of the pendant droplet test.

This is shown by the folds in the region around the dropping collar, which can be seen more distinctly after a more liquid retraction.

The wrinkles of the protein film analysis revealed that there has been no relaxation for 10 minutes after compression, which means that this surface layer is stable. Such findings show that BslA can self-assemble into a stable and complex superior film without the help of a protein or carbohydrate partner.

nordsb [41]

Answer:

0.4 swiss good(s) per U.S good(s)

Explanation:

firstly we calculate how many dollars we get per Frank so we will say $1/ 5 Swiss Franks =$0.2 which is similar to (5x =1, solve for x =1/5 / 0.2 in simple maths )per Swiss Franc thereafter we calculate the how many Swiss Francs per good compared to dollars per good we can get so therefore 2 Swiss Francs per good/$1 per good is the ratio of comparison , hence we treat f(X) as a function of swiss good(s) per U.S good, therefore f(X)= 2 x , knowing that x= 0.2 f(x)= 2(0.2) which will result in f(x)= 0.4.

In December 2014, Todd, a cash basis taxpayer, paid $1,200 fire insurance for the calendar year 2015 on a building he held for r
Kamila [148]

Answer: D. Todd should include the $500 in 2015 gross income in accordance with the tax benefit rule.

Explanation:

It should be noted that due to the fact that Todd is a cash basis taxpayer, he'll be able to deduct the one-year prepayment for insurance in the year that it was paid, 2014.

In this case, he deducted $1,200, then his net cost will be ($1200 - $500) = $700. In this case, Todd should then include the $500 refund in gross income for 2015 under the tax benefit rule.

The musical instrument store estimates costs of $18,750.00 annually to carry inventory of musical instruments and accessories. t
guapka [62]
To find the value of the inventory to the nearest cent: 
Estimated costs are: $18,750
Storage costs: 12%
Interest costs: 12%
Transportation costs: 5%
Let's add the costs up: 12% + 12% + 5% = 29%  

We are solving for the value of inventory so in this case we will make that X.
X = estimated costs/interest amounts 
X = $18,750/29% 
X = $18,750/0.29
X = $64,655.17

The value of the inventory is $64,655.17

To check your work you can take $64,655.17 and multiply it by 29%
= $18,750
