In the hydrophobic core of a folded protein, there are three alanine and five phenylalanine residues that are buried, and do not interact with water.
Assume:
In solution, waters can take on seven energetically equal states.
Two waters are ordered around each alanine in the unfolded state.
Six waters are ordered around each phenylalanine in the unfolded state.
In the unfolded state, waters are ordered around alanine or phenylalanine residues and can take on only two energetically equal states.
What is the difference in the entropy of the water due to the burying of these residues as the protein folds?
Answer:
The difference In The entropy of The western due to The burying of these residues as the protein folds is 291J/K
Explanation:
According to the data we know that
total water molecule = 2 * number of Ala + 6 * number of phenylalanine
replacing we get
2 * 2 + 6 * 4 = 4 + 24 = 28
total water molecule = 28
next step
S folded = Rln728
we replace the data and we get that
8.31 * 28 * ln7 = 452J • K –1 • mol –1
S unfolded = Rln228
we replace the data and we get that
8.31 * 28 * ln2 = 161J • K –1 • mol –1
∆ S = S folded - S unfolded = 452-161 = 291J / K

Explanation:
Examination of the amino acid composition of a newly isolated protein indicates the presence of 10 lysines, 5 arginines, and 3 methionines. When the protein is treated with cyanogen bromide, four peptides are obtained. When it is treated with trypsin, 15 peptides are obtained. What do these results suggest regarding the sequence of the protein?
Answer:
It means that the cyanogen bromide hydrolyzes methionine residues with high efficiency, while trypsin is an enzyme that cuts proteins at lysine and arginine peptidic bonds, thereby producing 4 and 15 polypeptides, respectively.
Explanation:
Cyanogen bromide is a pseudohalogen compound that is used to cut the C-terminus of the methionine residues. On the other hand, the trypsin is an enzyme produced by the pancreas as trypsinogen that is used by the digestive system (intestine) to digest polypeptides.

Rice is an important food crop in the the world. Growing rice requires large amounts of water because the roots of rice plants must remain under water. Explain how genes could play a role in helping farmers grow rice using less water. 2 sentences, explain they could do (answerrrr ASAP)
Answer:
Rice plants possesses several traits which allow sthem to grow in large amount of water because standing water helps them to produce air channel known as aerenchyma that connects roots with shoots and transport oxygen to submerged tissues. Standing water also help many weed to grow and rice plants also takes nutrients from them as well.
Genes are responsible for the traits that allow rice plants to grow in large amount of water but if the gene of rice plant is genetically modified with new gene which is resistant to drought, that can allow the rice to grow in less water.
The genetically modified rice plant then do not require large amount of water and can grow easily.
Which statement regarding lung cancer is correct?
A. Individuals with emphysema are not at risk for lung cancer.
B. Lung cancers are not aggressive.
C. More Americans die from lung cancer than any other form of cancer.
D. Only smokers will develop lung cancer.
Answer:
The correct answer is: C. More Americans die from lung cancer than any other form of cancer.
Explanation:
Lung cancer is one of the most aggressive cancers in the world, and is also the cancer that kills the most people in America every year (it is estimated that almost 140,000 Americans die from this cancer every year).
Emphysema is a chronic pulmonary disease that occurs when the air sacs in the lungs, called alveoli, enlarge and get damaged. This condition is mostly caused by smoking, and makes up a very significant risk factor for lung cancer.
Even when smoking makes up a huge risk factor for developing this and other types of cancer, non-smokers can develop lung cancer as well.
Answer: A is wrong, emphysema is not a risk factor for lung cancer. Lung cancer is primarily due to exposure to tobacco smoke and carcinogens in the smoke. Emphysema is due to loss of alveolar surface areas due to destruction of alveolar surfaces.The results is loss enough surface area for oxygen and C02 exchange in the lungs.
Generally D is wrong lung cancer is not limited to smokers only, smoking just increases it risk. Passive smokers can also develop cancer.But 45-50 of lung cancers is due to smoking. Beneze inhale from rubber industries,and asbestos industries are other places where Lung cancer can be developed after exposure.
A type of lung cancer can be agressive.(SCLC) While others can be slow.
C is correct.
Thus A is Odd

Under physiological conditions, a polypeptide folds up into secondary structure. what are the most common secondary structure elements?
Answer:
The folding of polypeptide begin during translation of the polypeptide chain. Amino acids interact with each other to form three dimensional tertiary structure and secondary structure elements formed spontaneously as an intermediate before the formation of tertiary structure.
There are two common secondary structure elements formed that are alpha helices(α helix) and beta pleated sheets ( β pleated sheet). Both the structures are attcahed by a hydrogen bond which is present between amino hydrogen and carboxyl oxygen atoms in the peptide backbone.
Hence, the two common elements of secondary structure are alpha helices and beta sheets.

3. sensation
4. sensation
5. sensation
6. perception
7. perception
8. perception
9. sensation
10. perception
Explanation:
Sensation and perception are two processes which look very similar to each other but are a different process.
Sensation involves the sensory organs of the body which can sense the physical world around us whereas perception involves the process which involves the brain as it organizes and interprets the sensory input.
1. perception- Taste is considered the perception because the taste is interpreted in the brain.
2. perception- the sensory receptors send the signals about roughness to the brain where the brain tells that the substance has roughness.
3. sensation- playing a song in the grocery store is an example of sensation as the person has just listened to the music and is not interpreting whether it is good or bad.
4. sensation- smell involves the sensory receptors but the taste of the smell is perception therefore is the smell is considered a sensation.
5. sensation- the smell is sensation therefore sensation is correct.
6. perception- perception involves the memory, experience and emotions therefore recognizing Bob is considered perception.
7. perception- reminding of soup involves memory, therefore, is considered perception.
8. perception-loud sound involves the brain, therefore, is a perception
9. sensation-feel of cloth is by sensory receptors but the type of feel will be perception.
10. perception-colour and shape are recognised by the brain and depends on memory, therefore, are perception.

A patient is suspected of having low stomach acid, a condition known as hypochloridia. To determine whether the patient has
this condition, her doctors take a 16.00 mL sample of her gastric juices and titrate the sample with 3.76 x 10-4 M KOH. The
gastric juice sample required 5.87 mL of the KOH titrant to neutralize it.
Calculate the pH of the gastric juice sample. Assume the sample contained no ingested food or drink which might otherwise
interfere with the titration.
Answer:
pH of the gastric juice
[tex]3.86[/tex]
Explanation:
As we know,
In an acid base titration, the number of milimoles of acid is equal to the number of milimoles of base.
Milimoles [tex]=[/tex] Molarity [tex]*[/tex] Volume
Molarity of gastric juices [tex]*[/tex] Volume of gastric juices [tex]=[/tex] Molarity of KOH [tex]*[/tex] Volume of KOH
Substituting the given values in above equation, we get -
[tex]16 * X = 5.87 * 3.76 * 10^{-4}\\[/tex]
X represents the molarity of gastric juices
[tex]X = \frac{5.87 * 3.76 * 10^{-4}}{16} \\X = 1.379 * 10^{-4}[/tex]
pH of gastric juices is equal to log [tex]1.379 * 10^{-4}[/tex]
[tex]= - log 1.379 * 10^{-4}\\= - [-3.86]\\= 3.86[/tex]

What does it mean if the G2 checkpoint fails during cell Division
Answer:
If the checkpoint mechanisms detect problems with the DNA, the cell cycle is halted, and the cell attempts to either complete DNA replication or repair the damaged DNA.
Explanation:
The G2 DNA damage checkpoint is an important cell cycle checkpoint in eukaryotic organisms that ensures that cells don't initiate mitosis until damaged or incompletely replicated DNA is sufficiently repaired. Cells that have a defective G2 checkpoint enter mitosis before repairing their DNA, leading to apoptosis or death after cell division.
