Which set of combinations would make the percentage of water in urine DECREASE the most?a) LOW temperature of the sorroundings and LOW amount of activityb) LOW temperature of the sorroundings and HIGH amount of activityc) HIGH temperature of the sorroundings and LOW amount of activityd) HIGH temperature of the sorroundings and HIGH amount of activity
Answers
The urine is a sub-product of our metabolism, being excreted from the body to dispose of compounds, mostly urea. The medium composition of urine is 3% of urea and other compounds and 97% water. However, the amount of water will change depending on the amount of this liquid available in the body. During hot seasons, we tend to sweat more, trying to keep our bodies cooled. But sweating demands us to use the water available in our body, and we loose more water than in lower temperaures of the surrounding. Because of that, the urine may have a lower percentage of water, as we have less water available in our bodies. When we exercise or do some activity that demands more of our metabolism, our bodies also tend to heat and, therefore, we sweat, causing the same decrease in the percentage of water. Therefore, the correct answer is d) HIGH temperature of the sorroundings and HIGH amount of activity.
PART 2
Based on your prior high profile publications, you are hired into a tenure-track position at the prestigious National Institutes of Health. Part of the attraction of the position is a laboratory doing state-of-the-art sequencing. You approach the head of the sequencing group, Dr. Max, to explore using the genomic sequencer for your own research. Although Dr Max is happy to collaborate with you, he spells out conditions that include that only Dr. Maxʼs technician may operate the instrument, and that all the original data must remain with Dr. Max. In addition, any paper submitted for publication that contains data obtained using the instrument must be reviewed by Dr. Max prior to submission, and he must be included as a co-author, with his two technicians acknowledged for their expertise.
Discussion Questions
1. Are the conditions requested by Dr. Max reasonable? What if his equipment was purchased for the whole Institute and his lab was considered a core facility? What do you think of the request that Dr. Max keep all original data? What about the requirement that he be an author on the resulting publications?
2. What do you think is an appropriate way to handle the contribution of the technicians who actually operated the sequencer? What about a technician in your lab who performed several of the experiments?
PART 3
Dr. Wong has developed a novel approach for analysis of genomic sequence data that is available on open source websites but is cumbersome to implement. After meeting Dr. Wong at a lab seminar, you mention that you plan to implement the method but you havenʼt been able to hire someone with the right computational experience. After the discussion, you share your data with him and about a week later you receive a series of summary figures, as well as an interpretation of the data and some ideas about additional genes to analyze and experiments to perform. Approximately 9 months later, you receive an angry email forwarded from your lab chief where Dr.Wong expresses outrage that you have published a paper using not just the analytic method but also
validating some of the genes that he had proposed. Dr. Wong expressed the opinion that based on his analysis and reporting the data back to you, as well as the fact that interpretation of the results at the level of predicting specific genes and pathways, required experience and insight and that was sufficient to have warranted co-authorship.
Discussion Questions
1. Was Dr. Wong justified in being upset? Are there corrective actions that you should take?
2. What actions could you have taken to clarify collaborative and authorship roles, and when might you have taken those steps? What were your expectations when you shared your data with him originally
Case # 3 ‒ Clinical Collaborations
A physician scientist and a molecular biologist are collaborating on a series of studies that involve cancer clinical trial subjects and biospecimens from those participants. The goal is to correlate genetic profiles with patient outcomes in response to the same protocol therapy. The clinician enrolls the subjects and his team obtains the samples which are processed in the molecular biologistʼs lab; i.e., germline and tumor DNA is prepared and preserved, and cancer cell lines are grown from the primary tumor. Both DNA and cell lines are kept in a facility readily accessible to both collaborators. The molecular biologist believes that there are important correlational genomic findings, apart from the clinical data, that merit separate publication. He prepares a manuscript that will need to have the clinical data added, but the clinician refuses to provide them, saying the report is premature. In the dispute that follows, the physician scientist asserts ownership of the DNA and cell lines from patient samples. The dispute is brought to you as the department head to mediate.
Discussion Questions
1. What are the data ownership issues for this collaboration? Who owns the clinical data? Who owns the DNA and cancer cells lines?
2. Who should have access to, and use of, the clinical data and the materials prepared from patient samples?
3. What could a publication agreement made at the beginning of the collaboration have
included?
Answers
The conditions requested in the publications are reasonable because he is the head of the department and has the authority to take care of the equipments.
What is a publication?
It should be noted that publication means the preparation and issuing a book, journal, or piece of music for public sale.
In this case, the conditions requested by Dr. Max are reasonable as he is the head of the department and has the authority to take care of the equipments.
Since we are hired at the institution, we need to submit the data to them. If the equipment was purchased for the whole institution then is also allowed to work on equipment.
Here, Dr. Max can keep all the data because he is the head. Also, about his requirement to be an author, this is wrong because there is no contribution from him in the work.

Answers
Soil is best defined as a mixture of minerals, air, water, and humus. So the right option is Soil is made up of minerals, air, water, and humus.
Soil is a mixture of minerals, air, water, and organic matter that provides the necessary nutrients and physical support for plants to grow. It is a living ecosystem that is home to millions of microorganisms, fungi, and other organisms that contribute to its health and productivity.
The minerals in soil come from the breakdown of rocks and other geological materials. Air and water are essential for soil structure and nutrient transport. Humus, or organic matter, is made up of dead plant and animal material that decomposes over time, adding nutrients and improving soil structure.
Soil is an important resource that plays a crucial role in agriculture, forestry, and environmental sustainability. It provides a habitat for many plant and animal species, helps regulate the Earth's climate, and plays a role in the carbon cycle.
However, soil can be degraded through erosion, overuse, and pollution. It is important to protect and manage soil resources to ensure their continued health and productivity for future generations.

Answers
Warm water rests on top of cooler water during summer zonation in temperate waters because warm water is less dense. Surface water that is cooling in the autumn thickens and combines with lower water.
Warm water condenses on top of cooler water during the summer months in temperate waters. This is because heated water is less dense than frigid water, creating the thermocline, a thermal boundary. Because the warm, oxygen-rich top layer and the frigid, nutrient-rich bottom layer do not interact, the surface layer is deficient in nutrients.
The water at the top sinks and mixes with the deeper water through thermal stratification as it cools and becomes denser in the autumn. The development of phytoplankton and other aquatic creatures can be supported by this process, which aids in bringing air and nutrients from the bottom layer to the surface. This mixing is necessary to preserve a balanced ecology in temperate waters and avoid oxygen loss, which could have a detrimental effect on marine life.

What are amphibians?
Any member of the group of vertebrate animals distinguished by their capacity to utilize both aquatic and terrestrial environments is referred to as an amphibian (class Amphibia). The word amphibian, which means "living a double life" in Greek, refers to this dual lifestyle, even though some species are entirely aquatic and others are permanent terrestrial residents.
There are now 8,100 different species of amphibians. They first appeared during the Middle Mississippian Epoch, around 340 million years ago. They were one of the first groups to depart from the ancestors of fish-tetrapods when animals evolved from purely aquatic forms to terrestrial ones.
Frogs and toads (order Anura), newts and salamanders (order Caudata), and caecilians are today's amphibians (order Gymnophiona). Despite having remarkably distinct body types, these three groups of contemporary amphibians—which are assumed to have descended from a single radiation of prehistoric amphibians—are most likely the closest relatives of one another.
Therefore, the survival of amphibians is dependent on land and water resources.

Why do leaves change color in the fall?
- their roots stop absorbing minerals
- their roots stop absorbing water
- they stop photosynthesis
- they stop making chlorophyll
Answers
The correct answer is D. They stop making chlorophyll
Explanation:
The regular green color in leaves is mainly the result of chlorophyll, which is essential for photosynthesis. This substance stops being produced by plants during the fall, and this causes leaves to lose their characteristic color. Additionally, this process is the result of shorter days, and therefore fewer daylight hours, which reduces or stops the production of chlorophyll. At the same time, the carotenoids which are red, yellow, and orange pigments begin to be visible. Thus, the reason leaves change color in the fall is that they stop making chlorophyll.

True or False: Purine is connected to pyrimidine using oxygen bonds.
Answers
Answer:
False
Explanation:
In DNA double helix molecule, there are four types of nitrogenous bases: adenine, guanine, cytosine and thymine. Purines (i.e., adenine, guanine) and pyrimidines (i.e., cytosine and thymine) hold DNA strands together via hydrogen bonds. In base pairing, guanine always pairs with cytosine through 3 hydrogen bonds, while adenine always pairs with thymine by 2 hydrogen bonds. Hydrogen bonds are a type of dipole–dipole interaction where a hydrogen atom is covalently bonded to a very electronegative atom (e.g., Nitrogen or Oxygen).
