The Center for Disease Control publishes articles explaining the causes of seasonal West Nile virus. Research proves mosquitoes

in freshwater ecosystems spread the disease to humans and other organisms. How do mosquitoes transmit the West Nile virus to other organisms? Question 9 options: Mosquitoes transmit the virus as parasites which feed on the blood of host organisms and inject the virus during feeding. Mosquitoes transmit the virus as hosts who feed on the blood of organisms and inject the virus during feeding. Mosquitoes transmit the virus when they land on the skin of an organism. Mosquitoes transmit the virus by preying on organisms and spreading the virus on contact.

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.

How many grams of sodium chloride are contained in 250.0 g of a 15% NaCl solution?
kramer

Given concentration of NaCl=15%

Means ,

In every 100g of Solution 15g of NaCl is present .

Now

  • Given mass=250g

So ,

\\ \Large\sf\longmapsto 250\times 15\%

\\ \Large\sf\longmapsto 250\times \dfrac{15}{100}

\\ \Large\sf\longmapsto 37.5g

<u>37.5g of NaCl present in 250g of solution.</u>

Determine the number of moles of C5H12 that are contained in 357.4 g of the compound.
AlladinOne [14]

Answer: 4.96 moles

Explanation:

C5H12 is the chemical formula for pentane, the fifth member of the alkane family.

Given that,

number of moles of C5H12 = ?

Mass in grams = 357.4 g

Molar mass of C5H12 = ?

To get the molar mass of C5H12, use the atomic mass of carbon = 12g; and Hydrogen = 1g

i.e C5H12 = (12 x 5) + (1 x 12)

= 60g + 12g

= 72g/mol

Now, apply the formula

Number of moles = Mass / molar mass

Number of moles = 357.4g / 72g/mol

= 4.96 moles

Thus, 4.96 moles of C5H12 that are contained in 357.4 g of the compound.
