Every year thousands of people in the UK have heart attacks.
A heart attack is caused when the heart muscle cells do not get enough oxygen, causing the cells to die.
Statins and stents are two treatments used to reduce the risk of someone having a heart attack.
Evaluate the use of statins compared with the use of a stent to reduce the risk of a heart attack. [6 marks]
Answers
Statins lower cholesterol and prevent plaque buildup, while stents restore blood flow. Statins are preventive, stents are reactive; both reduce heart attack risk (option b).
Statins are medications that help reduce cholesterol levels and prevent plaque buildup in the arteries, thus decreasing the risk of heart attacks.
They are typically used as a preventive measure for individuals with high cholesterol or existing heart issues. Stents, on the other hand, are small mesh tubes inserted into narrowed or blocked arteries to restore blood flow.
They are a reactive treatment, used after detecting significant artery blockage or following a heart attack.
Both statins and stents have their own advantages in reducing heart attack risk, with statins acting as a preventive measure and stents providing immediate relief to blocked arteries.

Background: You are a senior scientist at the CDC. While reviewing reports you see that there is a new infection that has surfaced in a local county. The agent who managed the incident wrote this in their notes:
“…..Infection spreads rapidly through physical contact. Once on the skin, this organism is able to break down keratin and infect the lower portions of the dermis. This organism has a Gram+ cell wall, is circular in appearance and very small. While not a traditional medication, the patient responded well to a drug that targeted mitochondria….” Do you think that this is the best medication to use on the patient? Explain why this medication would or would not work.
Thanks!
Answers
While the notes indicate that the patient responded well to the drug, there is no information provided about the mechanism of action of the drug or the specific type of infection that the patient had. It is also unclear whether the drug was specifically designed to treat this type of infection or if it was used off-label.
Additionally, while the notes mention that the organism has a Gram+ cell wall and is circular in appearance, there is no information about its genetic makeup or other characteristics that could provide insight into the most effective treatment options.
Therefore, it is not possible to say definitively whether the drug that targeted mitochondria is the best medication to use on the patient without further information. As a senior scientist at the CDC, I would recommend conducting further research and testing to identify the most effective treatment options for this new infection.

What is one way that calcitonin and parathyroid hormone maintain homeostasis?
A. Calcitonin stimulates the kidneys to excrete calcium when calcium levels are too high, while parathyroid hormone stimulates the kidneys to absorb calcium when calcium levels are too low.
B. Calcitonin stimulates the bones to excrete calcium when calcium levels are too high, while parathyroid hormone stimulates the bones to absorb calcium when calcium levels are too low.
C. Calcitonin stimulates the kidneys to absorb calcium when calcium levels are too low, while parathyroid hormone stimulates the kidneys to excrete calcium when calcium levels are too high.
D. Calcitonin stimulates the bones to absorb calcium when calcium levels are too low, while parathyroid hormone stimulates the bones to excrete calcium when calcium levels are too high.
Answers
Answer:
The way calcitonin and parathyroid hormone maintain homeostasis in the body is calcitonin stimulates the kidneys to excrete calcium when calcium levels are too high, while parathyroid hormone stimulates the kidneys to absorb calcium when calcium levels are too low (option A).
Explanation:
Calcitonin and parathyroid hormone have a role in maintaining the balance of calcium and phosphorus concentrations, but their effects are opposite.
The reduction of calcium levels promoted by calcitonin is based on:
Inhibition of intestinal absorption of calcium and bone resorption or decalcification. Increases the excretion of Calcium by the kidneys.On the other hand, parathyroid hormone increases calcium levels by performing the opposite effect of calcitonin:
It stimulates intestinal absorption and bone resorption. It increases renal calcium reabsorption.Both mechanisms contribute to maintain the levels of calcium, when it is high or low in the organism, collaborating with the maintenance of the homeostasis.
The other options are not acceptable because they do not describe the correct function of calcitonin and parathyroid hormone.

Which of the following ecosystem services do sharks provide?
Answers
Sharks help in the regulation of the Population of marine species.
Which of the following ecosystem services do sharks provide?Sharks provide several ecosystem services, including:
Regulation of Marine Populations: As top predators, sharks help regulate the populations of other marine species, which can prevent overgrazing of important habitats and help maintain the overall health of marine ecosystems.
Maintenance of Biodiversity: Sharks are a keystone species in many marine ecosystems, meaning that they play a critical role in maintaining the overall biodiversity of these ecosystems. By preying on a variety of species, sharks help ensure that no one species becomes too dominant, which can lead to imbalances in the ecosystem.
Carbon Sequestration: Some species of sharks, such as the whale shark, are filter feeders that consume large quantities of plankton. By removing plankton from the water, they help sequester carbon from the atmosphere and transport it to the ocean floor.
