To determine:
The reason as to why Ebola is such a deadly virus.
Concept introduction:
Ebola virus is an RNA (ribonucleic acid) virus known to cause Ebola hemorrhagic fever or Ebola virus disease. Signs and symptoms of this disease include fever, muscle pain, sore throat, headache, diarrhea, followed by decreased function of kidneys and liver. Internal and external bleeding may also occur, ultimately causing the death of the infected individual.

Explanation of Solution
Early symptoms of Ebola include vomiting, fever, diarrhea, muscle pain, headache. This makes it difficult to diagnose the disease and it is mistaken for typhoid, malaria, cholera, and other diseases. The virus is deadly as there is a high risk of lethality in its infection.
Ebola is considered a deadly virus as there are higher chances of death in its infection.
To determine:
The reservoir of Ebola virus.
Concept introduction:
Ebola virus is known to cause Ebola hemorrhagic fever or Ebola virus disease. Signs and symptoms of this disease include fever, muscle pain, sore throat, headache, diarrhea, followed by decreased function of kidneys and liver. Internal and external bleeding may also occur.

Explanation of Solution
The exact reservoir of the virus is not known. It makes it difficult to detect antibodies formed against the virus. However, fruit bats are considered to the host of this virus. Only 3% of the fruit bat species are sampled to date and thus, it is really difficult to determine the exact reservoir of the virus.
The exact reservoir of the virus is still unknown.
To determine:
Transmission of Ebola virus.
Concept introduction:
Ebola virus is an RNA (ribonucleic acid) virus known to cause Ebola hemorrhagic fever or Ebola virus disease. Signs and symptoms of this disease include fever, muscle pain, sore throat, headache, diarrhea, followed by decreased function of kidneys and liver. Internal and external bleeding may also occur, ultimately causing the death of the infected individual.

Explanation of Solution
Although Ebola is not a “successful” virus, it is a global concern because the virus is deadly and it spreads through direct contact with bodily fluids and contaminated fomites such as clothes or bed linens from infected individuals.
The virus can be transmitted between family members, caregivers at home, and also through contact with dead bodies. The virus can also be transmitted from infected patients to the medical staff. There were several cases in which physicians died after treating the patient. The exact reservoir of the virus is not known. It makes it difficult to detect antibodies formed against the virus.
Ebola virus is transmitted through direct contact with body fluids and contaminated fomites.

Describe one way by which Nodal gets amplified in this region." My understanding of this is that there are a few ways nodal is amplified though I'm not sure if this is specifically occurs on the opposite side of the AVE. 1. pronodal cleaved by protease -> active nodal 2. Nodal -> BMP4 -> Wnt-> nodal 3. Nodal-> Nodal, Fox1 binding site 4. BMP4 on outside-> nodal Are all of these occuring opposite to AVE?arrow_forwardIf four babies are born on a given day What is the chance all four will be girls? Use genetics lawsarrow_forward

What is the phenotype, and why is the phenotype so similar? Is the phenotype going to be that there is a disruption of the formation of the neural tube for both of these because bottle cell formation is necessary for the neural plate to fold in forming the neural tube and Shroom3 is further needed to close the neural plate? So since both Plekhg5 and Shroom3 are used in forming the neural tube, injecting the mRNA will just lead to neural tube deformity?arrow_forwardWhat are some medical issues or health trends that may have a direct link to the idea of keeping fat out of diets?arrow_forward
