Answer:
The correct answer is - Mosquitoes transmit the virus as parasites which feed on the blood of host organisms and inject the virus during feeding.
Explanation:
According to the CDC, the seasonal West Nile virus is caused by the mosquitoes of freshwater transmit this disease to humans and others. These mosquitoes are feed on the birds and pick these viruses.
These viruses stick on mosquitoes and when they feed on the blood of humans they transmit these viruses by injecting viruses into the blood of humans.
Answer : The partial pressure of the
in the tank in psia is, 32.6 psia.
Explanation :
As we are given 75 %
and 25 %
in terms of volume.
First we have to calculate the moles of
and
.
![\text{Moles of }CO_2=\frac{\text{Volume of }CO_2}{\text{Volume at STP}}=\frac{75}{22.4}=3.35mole](https://tex.z-dn.net/?f=%5Ctext%7BMoles%20of%20%7DCO_2%3D%5Cfrac%7B%5Ctext%7BVolume%20of%20%7DCO_2%7D%7B%5Ctext%7BVolume%20at%20STP%7D%7D%3D%5Cfrac%7B75%7D%7B22.4%7D%3D3.35mole)
![\text{Moles of }N_2=\frac{\text{Volume of }N_2}{\text{Volume at STP}}=\frac{25}{22.4}=1.12mole](https://tex.z-dn.net/?f=%5Ctext%7BMoles%20of%20%7DN_2%3D%5Cfrac%7B%5Ctext%7BVolume%20of%20%7DN_2%7D%7B%5Ctext%7BVolume%20at%20STP%7D%7D%3D%5Cfrac%7B25%7D%7B22.4%7D%3D1.12mole)
Now we have to calculate the mole fraction of
.
![\text{Mole fraction of }CO_2=\frac{\text{Moles of }CO_2}{\text{Moles of }CO_2+\text{Moles of }N_2}](https://tex.z-dn.net/?f=%5Ctext%7BMole%20fraction%20of%20%7DCO_2%3D%5Cfrac%7B%5Ctext%7BMoles%20of%20%7DCO_2%7D%7B%5Ctext%7BMoles%20of%20%7DCO_2%2B%5Ctext%7BMoles%20of%20%7DN_2%7D)
![\text{Mole fraction of }CO_2=\frac{3.35}{3.35+1.12}=0.75](https://tex.z-dn.net/?f=%5Ctext%7BMole%20fraction%20of%20%7DCO_2%3D%5Cfrac%7B3.35%7D%7B3.35%2B1.12%7D%3D0.75)
Now we have to calculate the partial pressure of the
gas.
![\text{Partial pressure of }CO_2=\text{Mole fraction of }CO_2\times \text{Total pressure of gas}](https://tex.z-dn.net/?f=%5Ctext%7BPartial%20pressure%20of%20%7DCO_2%3D%5Ctext%7BMole%20fraction%20of%20%7DCO_2%5Ctimes%20%5Ctext%7BTotal%20pressure%20of%20gas%7D)
![\text{Partial pressure of }CO_2=0.75mole\times 300Kpa=225Kpa=225Kpa\times \frac{0.145\text{ psia}}{1Kpa}=32.625\text{ psia}](https://tex.z-dn.net/?f=%5Ctext%7BPartial%20pressure%20of%20%7DCO_2%3D0.75mole%5Ctimes%20300Kpa%3D225Kpa%3D225Kpa%5Ctimes%20%5Cfrac%7B0.145%5Ctext%7B%20psia%7D%7D%7B1Kpa%7D%3D32.625%5Ctext%7B%20psia%7D)
conversion used : (1 Kpa = 0.145 psia)
Therefore, the partial pressure of the
in the tank in psia is, 32.6 psia.

<u>Explanation:</u>
<u>When the zebra eats grass, it gets energy from the sun that has been stored in the grass. Similarly, the lion obtains energy stored in the zebra. The zebra and lion both obtain the sun's energy indirectly from the energy that the grass obtained through photosynthesis. </u>
