B. because it has to be 'alerted' that a foreign invader has been spotted
C. because it alerts the immune system when a foreign invader is spotted
D. because it protects against a specific type of pathogen
Answer:
A is the answer
Explanation:
This is what skin does, it blocks outside material from getting into the body regardless of what it is.
What are the gametes that would be formed for the following genotype: Aa?
Answer:
An individual with the genotype Aa can make two types of gametes: A and a. Since this is a random process, the individual will, on average, make equal numbers of each gamete. (Frequency of 1/2 for each gamete). A second individual with genotype Aa can make two types of gametes: A and a.
As we learned plasma proteins Fibrinogen and Prothrombin are both needed for coagulation. However, there is much more fibrinogen (4% of plasma proteins) compared to prothrombin (present in only small traces). Applying your knowledge of enzymes and clotting cascade, explain the difference in their abundance.
Answer:
Fibrinogen is present in much higher amounts than what is required for coagulation while Prothrombin is present in low amounts in order to prevent excess conversion to thrombin during blood clotting
Explanation:
Fibrinogen is functional for processes such as inflammation, atherogenesis and not for blood Coagulation and they are required to form Fibrin fibers which will in turn form blood clots. Fibrinogen is present in much higher amounts than what is required for coagulation while
Prothrombin is present in low amounts in order to prevent excess conversion to thrombin during blood clotting. and this is because increased concentrations of thrombin will lead to an extensive intravascular thrombosis
A scientist isolates a disease-causing particle. Which of the following properties would indicate that the particle is a virus and not a bacterium?

Choose one of the following scenarios and answer the questions provided. Support your answers using scientific reasoning and discussing possible impacts to individuals, society, and the environment. Be sure to also discuss any medical or ethical issues that may apply. (10 points)
Scenario 1:
Genetic engineering can be used to create more productive strains of farm animals. By adding genes to an animal's DNA, the animal can be made to produce milk or meat containing vital nutrients that would not be found naturally in those products. This provides a greater amount of nutrients per serving of milk or meat.
Do you think that this type of genetic engineering should be pursued? Explain your answer. (5 points)
What are some possible impacts (positive and negative) of this type of genetic engineering on individuals, society, and the environment? (5 points)
Scenario 2:
In the future, doctors may be able to evaluate your DNA to check for genetic markers related to specific medical conditions or harmful reactions to medications. Your personalized genetic profile could be kept on record and referred to in order to develop personal medical treatment based on your unique DNA sequencing. Scientists have found that just small variations in a specific section of your DNA can help determine how well some medications can work for you or if they would be beneficial at all.
Would you want to have your DNA profile kept in your medical record as a reference for your doctors? Explain your answer. (2 points)
What are potential pros and cons of having such tests done and referring to DNA sequences when determining a patient's medical treatment? (5 points)
Describe how the availability of this technology might affect the frequency of genetic diseases in individuals and populations. (3 points)
Answer:
1. It should be, it has been for about 20 years, and it's really not much different in the end than breeding animals to have particular traits. There are always concerns about genetically engineered animals/plants affecting the environment in unexpected negative ways, but I can't think of an example where the fears didn't turn out to be baseless.
2. Yes. First, as you point out, it would be a great advance in pharmacology, to be able to tailor drugs and their doses to me. The pros involve better medical treatment. The cons involve privacy issues like insurance companies denying coverage to people with genetic risk factors. Looking at DNA markers wouldn't affect the frequency of genetic diseases, but it would allow detection of them earlier. And OK, actually I suppose that if people used this information to avoid having children with genetic diseases, some might decrease in frequency.

Which of the following irrigation methods is most likely to result in salinization of the soil, especially if the agricultural fields are located in a warm climate with consistent sunlight
A Spray irrigation
Furrow irrigation
Flood irrigation
Drip Irrigation
Answer: Furrow Irrigation (B)
Explanation:
Furrow irrigation
Salinization of the SoilThe accumulation of water-soluble salts in the soil is known as salinization. Excess salts inhibit crop growth by decreasing their ability to absorb water, making salinization a resource concern.Surface irrigation in which trenches or "furrows" are created between crop rows in a field is known as furrow irrigation. Furrow irrigation is done by laying down short parallel channels down the length of the field in the direction of the predominant slope.Furrow irrigation is most likely to result in salinization of the soil, especially if the agricultural fields are located in a warm climate with consistent sunlightFor more information:

Several examples of antisense RNA regulating translation in bacterial cells have been discovered. Molecular geneticists have also used antisense RNA to artificially control transcription in both bacterial and eukaryotic genes. To inhibit the transcription of a bacterial gene with antisense RNA, what sequence might the antisense RNA contain
Answer:
An antisense sequence with complementary to the target mRNA encoded by the gene of interest
Explanation:
An antisense sequence is usually a short RNA sequence specifically designed in the laboratory to bind by complementary to the DNA/RNA sequence of interest (usually a target mRNA) whose expression is desired to be inhibited. When an antisense bind to its target mRNA, the antisense sequence acts to block translation, thereby inhibiting protein synthesis. Moreover, it has been shown that the double-stranded antisense-RNA complexes may also increase the susceptibility of the target sequence to RNase H digestion.

The production of red blood cells is regulated by a feedback loop involving erythropoietin. In non-disease states, the production of red blood cells is equal to the destruction of red blood cells, thus maintaining sufficient red blood cells to deliver adequate oxygen to the body's tissues. However, when the number of red blood cells decrease and oxygen levels are low, erythropoietin is produced by the liver and kidneys to increase the production of red blood cells. Is this a positive or negative feedback loop
Answer:
Negative feedback.
Explanation:
The production of erythropoietin by the liver and kidneys is a negative feedback because with the production of erythropoietin, our body tends to move to become more stable state. The erythropoietin is produced by the liver and kidneys to increase the production of red blood cells if the quantity of red blood cells are lower than the normal range. If the number of red blood cells are decreases the oxygen level in our body is low that leads to unstable condition of the body but when the concentration of red blood cells increases, the body move towards stability.

Based on the patient's symptoms and doctor's initial prognosis, how does dehydration affect a person's blood flow and blood pressure?
The patient's blood viscosity would increase, causing blood flow to increase and blood pressure to decrease
The patient's blood viscosity would decrease, causing the blood flow and blood pressure to remain at a stable rhythm
The patient's blood viscosity would decrease, causing the blood flow to decrease and the blood pressure to also decrease
The patient's blood viscosity would increase, causing the blood flow to decrease and the blood pressure to increase
Answer:
Maintaining a normal blood volume is necessary for blood to be able to adequately reach all of the tissues of your body. When you're very dehydrated, your blood volume can decrease, leading to a drop in blood pressure. When blood pressure drops too low, your organs won't receive the oxygen and nutrients they need. might be what you are looking for but if not i will change it
