Answer:
The correct answer is option (c) "water".
Explanation:
Cells that are undergoing aerobic respiration and are exposed to a radioactive carbon isotope in the form of C6H12O6 will have radiolabeled its molecules that are involved in aerobic respiration and contain carbon. In this case, the only molecule that does not contain carbon in the options is water, therefore water will not be radiolabeled. Water is comprised of two atoms of hydrogen and one atom of oxygen, while pyruvate, NADH and CO2 all contain carbon.
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]

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.

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). Understanding how our human physiques conduct themselves helps us gain the knowledge to be able to stay alive.

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.
Which of the following two statements describe benefits of bio technology in medicine
1. using stem cells to treat disease
2. using antibiotics to treat infection
3. diagnosing genetic diseases
4. producing antibodies such as antitoxins
5. curing diseases such as smallpox
The correct answers are 1. Using stem cells to treat disease, and 3. Diagnosing genetic diseases.
Explanation
Biotechnology is a science that covers different areas such as chemistry, biology, and technology, to improve or facilitate procedures related to living organisms by manipulating living or parts of these in areas such as agriculture, medicine, and pharmacy. In the area of medicine, biotechnology is in charge of working with DNA to improve people's health. Also, it is in charge of investigating the cells to know in depth the problems that trigger diseases or genetic problems. Another use of biotechnology in medicine is through the use of stem cells in treatments for self-renewal or regeneration of damaged tissues. So, the correct answers are 1. Using stem cells to treat disease, and 3. Diagnosing genetic diseases.

Michael's team is presenting a robot before their examiners. What do they need which is a definitive description of the final product or a
system?
While presenting the robot examiners are up with various questions like what purpose it will serve what features it must include, what
functions it must perform to be acceptable. Michael's team needs to specify the ________
of the robot to examiners.
Answer:
Applicability
Explanation:
The best way to present the importance of any research is to show its application and future scope. Here in this case too Michael needs to define the various fields and aspects of life where a robot can help and assists human being. He must also outline the future scope of development through which its application range could be increased to various other fields along with moving towards more complex application.
Answer:
specifications
Explanation:
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.

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.

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.
