What evidence supports or contradicts the hypothesis that the invasive Burmese pythons are responsible for recent increases in human Everglades virus infections, and how can this hypothesis be evaluated using the available data?
Overall, while the hypothesis that invasive Burmese pythons are responsible for recent increases in human Everglades virus infections is plausible, it requires further investigation and evidence to confirm or refute it definitively.
The hypothesis that invasive Burmese pythons are responsible for recent increases in human Everglades virus infections is based on the observation that the number of human cases of the virus has increased since the pythons have become established in the Everglades. However, this correlation does not necessarily mean that the pythons are the direct cause of the increase in infections.
To evaluate this hypothesis, several lines of evidence can be considered. One approach would be to investigate the ecology and behavior of the pythons and their interactions with the natural hosts of the Everglades virus, such as rodents and other small mammals. This could help to determine whether the pythons are likely to be vectors for the virus, or whether they might be indirectly facilitating transmission by altering the ecosystem in ways that favor the virus or its hosts.

in the S phase, the number of chromatids doubles during replication. What are the chromatids bonded by? What does this mean for the number of chromosomes present in the cell?
In the S phase of the cell cycle, DNA replication occurs and each chromosome is duplicated, resulting in the formation of two identical sister chromatids. The chromatids are bonded by a centromere, which is a specialized region of DNA that holds the chromatids together. This means that after replication, each chromosome consists of two sister chromatids that are held together at the centromere.
Since the number of chromatids doubles during replication, the number of chromosomes present in the cell remains the same. For example, if a cell had 10 chromosomes before S phase, it will still have 10 chromosomes after replication, but now each chromosome will consist of two sister chromatids.

where is blood filtered in the kidney? How do oncotic and hydrostatic pressures play a role here? what is the overall net movement between the blood and bowman's space?what would happen if these is a buildup of urine behind a stone for example?consult pg 371 if confused
Blood is filtered in the kidney in a structure called the glomerulus. Oncotic pressure and hydrostatic pressure play a role in the filtration process by affecting the overall net movement between the blood and Bowman's space. The overall net movement between the blood and Bowman's space is the movement of fluids and solutes out of the capillaries and into Bowman's space. If there is a buildup of urine behind a stone, it can cause a blockage in the urinary system, leading to a backup of pressure.
The glomerulus is a network of small blood vessels called capillaries that are surrounded by a Bowman's capsule. The capillaries have a high pressure, which allows them to filter small molecules such as waste products, electrolytes, and water out of the blood and into Bowman's space.
Oncotic pressure and hydrostatic pressure play a role in this process. Hydrostatic pressure is the force exerted by the blood pushing against the walls of the capillaries. This pressure helps to push fluids and solutes out of the capillaries and into Bowman's space.
The oncotic pressure is the force exerted by proteins in the blood that tend to draw fluids back into the capillaries. These opposing pressures help to regulate the movement of fluids and solutes across the capillary walls.
The net movement between the blood and Bowman's space is typically filtration, where water and solutes are forced from the blood into the Bowman's space, eventually becoming part of the filtrate that moves through the nephron. This is influenced by the balance between hydrostatic pressure and oncotic pressure.
If there is a buildup of urine behind a stone, for example, it can lead to an increase in pressure within the kidney. This may cause pain, swelling, and potential damage to the kidney. Additionally, the increased pressure could affect the glomerular filtration rate, resulting in decreased filtration efficiency and potential kidney problems. In some cases, it may require medical intervention to remove the stone and alleviate the pressure.
In summary, blood is filtered in the glomerulus and the different pressures play an important role in the filtration processes, and any stone deposition can affect kidney functions.
