Based on the results, which of the following best describes what Protein X is a transcription factor.
What are transcription factors?Transcription factors are proteins that contain at least two functional domains: one binding with DNA and the other binding with RNA polymerase. These proteins control when, where and how the genes will be transcribed, being the basis for the control of gene expression.
In this case the protein X is a transcription factor which means proteins that help turn specific genes "on" or "off" by connecting to nearby DNA. Transcription factors that are activators drive the transcription of a gene.

What molecule do red blood cells more readily bind with if they are given a choice between it and O2?
Answer:
Hemoglobin is a protein found in red blood cells that is comprised of two alpha and two beta subunits that surround an iron-containing heme group. Oxygen readily binds this heme group.
If water is moving from inside of a red blood cell to outside of the cell into the blood plasma, the solution is
a. hypotonic
b. hypertonic
c. isotonic
d. monotonic
Answer:
hypertonic
Explanation:
If a cell is placed in a hypertonic solution, there will be a net flow of water out of the cell, and the cell will lose volume. A solution will be hypertonic to a cell if its solute concentration is higher than that inside the cell, and the solutes cannot cross the membrane.
List the ways eukaryotic cells can modify the original mrna transcript.
Answer:
The pre-mRNA has to go through some modifications to become a mature mRNA molecule that can leave the nucleus and be translated.
Explanation:
Eukaryotic pre-mRNAs are modified with a 5' methylguanosine cap and a poly-A tail. These structures protect the mature mRNA from degradation and help export it from the nucleus. These include splicing, capping, and addition of a poly-A tail, all of which can potentially be regulated – sped up, slowed down, or altered to result in a different product.

Answer:
The importance of plant genetic diversity (PGD) is now being recognized as a specific area since exploding population with urbanization and decreasing cultivable lands are the critical factors contributing to food insecurity in developing world. Agricultural scientists realized that PGD can be captured and stored in the form of plant genetic resources (PGR) such as gene bank, DNA library, and so forth, in the biorepository which preserve genetic material for long period. However, conserved PGR must be utilized for crop improvement in order to meet future global challenges in relation to food and nutritional security. This paper comprehensively reviews four important areas; (i) the significance of plant genetic diversity (PGD) and PGR especially on agriculturally important crops (mostly field crops); (ii) risk associated with narrowing the genetic base of current commercial cultivars and climate change; (iii) analysis of existing PGD analytical methods in pregenomic and genomic era; and (iv) modern tools available for PGD analysis in postgenomic era. This discussion benefits the plant scientist community in order to use the new methods and technology for better and rapid assessment, for utilization of germplasm from gene banks to their applied breeding programs. With the advent of new biotechnological techniques, this process of genetic manipulation is now being accelerated and carried out with more precision (neglecting environmental effects) and fast-track manner than the classical breeding techniques. It is also to note that gene banks look into several issues in order to improve levels of germplasm distribution and its utilization, duplication of plant identity, and access to database, for prebreeding activities. Since plant breeding research and cultivar development are integral components of improving food production, therefore, availability of and access to diverse genetic sources will ensure that the global food production network becomes more sustainable. The pros and cons of the basic and advanced statistical tools available for measuring genetic diversity are briefly discussed and their source links (mostly) were provided to get easy access; thus, it improves the understanding of tools and its practical applicability to the researchers.

Hey can someone please help me with these questions. Im having a hard time with them.
Answer:
See below.
Explanation:
1. C. an increase in clean water sources.
If we think about this in terms of humans, our growing population, this should be the correct answer. Through the creation and usage of carbon emissions (ie. using gas to power cars and the smoke that comes out as exhaust in those cars) decreases are quality quickly. Additionally, this directly relates to an increase of global warming, as the contribution of greenhouse gases ups the temperature on earth. As wood and the materials with it are a large source of material for us, deforestation is common and happens all the time, so that in itself (along with all the other points stated) are direct contributions/ causes of our growing population.
Thus, the answer will be C.
2. B. Burning fossil fuels in power plants.
Dumping waste matter into ocean waters doesn't essentially rise the temperature of the earth, as is defined as global warming. It's bad, yes, but not a direct/ big contributor to it. Using pesticides on agricultural crops, too, doesn't necessarily affect global warming as much as the other options provided. Now, in clearing native forests with industrialization, that's where it gets tricky. We use machines and whatnot to do this, so you could say that this is a huge factor. However, this isn't the case, as global warming is most affected by the burning of fossil fuels (you know- "warming" and "burning" do kinda correlate for a reason here).
Thus, the answer is B.
3. C. the increased supply of resources.
Graph 2 starts to go up slightly before it skyrockets upward, slowly starting to level out afterward, yes? So, what'll be the cause of this. Obviously if there's something increasing this and the population, a decrease won't be the answer. Additionally, if we're assuming both graph start out with the same amount of resources, then the demand would still be high, right? So our answer cannot be D. Now we're left with options A and C. While A may seem like a correct answer, this scenario depends more on quantity as opposed to quality (it won't matter how good the resources are if you don't have enough of it), so this will leave our answer to then be C.
4. D. for about 3 months.
If we take a look at the graph and where the carrying capacity is finally reached, we'll see this moment in time is on August 1st. Now, if we've initially started documenting this rabbit population on May 1st, we'll understand that there is a three month gap between them, thus providing us with the answer of 3 months.
If this is still a bit confusing as to why it's not 4 months (which may not be a problem for you but it always was when I was younger), you can think of it as this:
May to June is 1 month. June to July is 2 months. July to August is 3 months.
5. F. more access to contraception
Now, a few of these you can cross out quickly. It won't be option B because that would indicate a high jump in growth rate, it won't be option C because that has no direct impact on anything in this scenario, it won't be option D because high education is available in many places (meaning that it wouldn't affect anything in a specifically more developed country), and it won't be option E because that would lead to an increase. Now we're left with options A and F- which one is it?
A higher cost of living would definitely deter people from having kids, but would it lead to a slower growth rate? Not necessarily. People still have kids in harsh times, so that's not necessarily what would be the leading cause. More access to contraception, however, would lead to a slower growth rate. If people have more access to the means of not stopping them from having kids, and then they choose to take this option, then this would be the correct answer.
List 3 body systems that both humans and fish have in common.
Answer:
The systems areRespiratory systemDigestive systemExcretory system.The 3 body systems that both humans and fish have in common are circulatory, respiratory and digestive system.
What is body system?When we breathe in air, our lungs pull oxygen from it and transmit it into our bloodstream while also producing carbon dioxide. The gills function similarly in the majority of fish, although not all.
Fish consume food through their mouths, then they digest it in their esophagus.
The pyloric caeca, which are finger-shaped pouches that process food in the stomach and secrete digestive enzymes and absorb nutrients, are found in many fish.
Cold-blooded aquatic vertebrates called fish can be found in both freshwater and saltwater.
Similar to humans, they have a closed circulatory system in which a network of blood arteries keeps the blood constantly contained.
Thus, these are the three body systems.

why are scientists unsatisfied with using one type of element to determine the age of a rock?
Answer:
Different elements have different half lives, which means that certain elements are only useful for determining the age of a rock up to a certain age. Carbon-14, for example, is great for dating archeological finds as old as 50,000 years. But that's the limit of its usefulness. I would not be useful for dating dinosaur bones. For that you would need an element with a much longer half life, such as Uranium-238, which has a half life of more than a million years.

Which statement best describes cancer cells?
• They grow as a single layer of cells.
• They cease to reproduce after 20-50 mitotic divisions.
• They reproduce only when needed to replace missing cells.
• They are not regulated by contact inhibition.
Answer:
They are not regulated by contact inhibition.
Explanation:
The lack of contact inhibition control in cancer cells is what allows them to continue to reproduce. In non-cancerous cells, contact inhibition triggers cells to stop dividing and to grow when they come in contact with other cells. This control is lost when cells undergo malignant transformation.
