Question:

Explain the COVID-19 mRNA vaccine.

Ram M.

The mRNA vaccines against COVID-19 uses mRNA sequence responsible for the production of spike proteins normally found around the coronavirus' viral structure. The mRNA vaccines are introduced to our bodies. The mRNA borrow's the body's cellular machinery (i.e., nucleus) to initiate translation of such mRNA to produce polypeptide sequences for that specific spike protein. The spike proteins cannot infect the vaccinated person the way an active virus does. What it does is that the spike proteins trigger nearby white blood cells (macrophages, T-cells, etc,) to elicit an immune response. That's why vaccines like this cause mild side effects such as fever and fatigue. Before the white blood cells eliminate the spike proteins for good, memory T-cells will "remember" that specific spike protein. In this way, the body can produce antibodies specific to the Sars-CoV-2 whenever the vaccinated person gets exposed. Thus, making a person immune to such viral strain.

Question:

How is carbon dioxide sequestration approximated?

Ram M.

Carbon dioxide sequestered by a tree is estimated using a four-step calculation: 1. Calculate the total green weight (root system + above-ground) Above-ground = 0.25D^2H, if D>=11 = 0.15D^2H, if D<11 D = diameter at breast height in inches H = height in feet Root system = 0.20 x Above-Ground 2. Calculate the total dry weight Dry weight = 0.725 x Green weight 3. Calculate the carbon weight Carbon weight = 0.5 x Dry weight 4. Calculate the carbon dioxide weight CO2 weight = 3.6663 x Carbon weight

Question:

What questions can be asked when encountering an unusual or unknown organism?

Ram M.

1. Is this organism already classified by taxonomist or not? 2. If not, what are the gross anatomical descriptions that could guide us in classifying it according to its domain, kingdom, phylum, class, order, family, and genus? 3. Does the habitat of the organism tell anything about its behavior (feeding, mobility, etc.)? 4. If already classified, is it a native or an introduced/exotic species? 5. What could be the ecological significance of this organism in its local habitat?
