Answer:
gea
Explanation:
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]

Question 9
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.

Cardiac muscle causes movement in the
Answer:
(look at explanation)
Explanation:
Cardiac muscle tissue works to keep your heart pumping through involuntary movements. This is one feature that differentiates it from skeletal muscle tissue, which you can control. It does this through specialized cells called pacemaker cells. These control the contractions of your heart.
Cardiac muscle causes movement in the heart.
What is Cardiac muscle?A cardiac muscle is the type of muscle found only in the heart. It is also called the myocardium.
The cardiac muscles are only located in the heart because they are made up of features that are specialized in pumping blood powerfully and efficiently. These features include:
they are involuntary and intrinsically controlled,they are striated,they are branched and single nucleated.Therefore, cardiac muscle causes movement in the heart.

How does science directly affect you? Where will what you have learned lead you next? PLEASE HELP ME RIGHT NOW!!!!!!!
Answer: Literally everywhere. Having an at least basic level of science helps you in day-to-day situations. For example, cooking. Not only is it crucial to understand the chemical and physical processes when cooking, you should also understand the complexity of how these micro and macromolecule exchange processes affect you and your body. Another prime example is your health, or human processes. You might not realize this, but your body is a plethora of complex, interconnected systems and networks that work hard 24/7 to maintain homeostasis (keep you alive).

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

The essence of engineering design lies in finding workable solutions for a given set of specifications and constraints. Specifications are definitive descriptions of the final product or system—what purpose it will serve, what features it must include, what functions it must perform to be acceptable, etc.
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

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.
