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 magnesium are in sample containing 9.12+ 10 ^23atoms
Answer: There are 1.51 moles present in [tex]9.12 \times 10^{23}[/tex] atoms.
Explanation:
According to the mole concept, there are [tex]6.022 \times 10^{23}[/tex] atoms present in one mole of every substance.
Hence, moles present in [tex]9.12 \times 10^{23}[/tex] atoms are calculated as follows.
[tex]Moles = \frac{9.12 \times 10^{23}}{6.022 \times 10^{23}}\\= 1.51 mol[/tex]
Thus, we can conclude that there are 1.51 moles present in [tex]9.12 \times 10^{23}[/tex] atoms.

The volume of gas in a balloon is 1.90L at 21.0°C.The balloon is heated, causing it to expand to a volume of 5.70L. what is the new temperature of the gas inside the balloon?
Answer: The new temperature is [tex]63^{o}C[/tex].
Explanation:
Given: [tex]V_{1}[/tex] = 1.90 L, [tex]T_{1} = 21.0^{o}C[/tex]
[tex]V_{2}[/tex] = 5.70 L, [tex]T_{2} = ?\\[/tex]
Formula used to calculate new temperature is as follows.
[tex]\frac{V_{1}}{T_{1}} = \frac{V_{2}}{T_{2}}[/tex]
Substitute the values into above formula as follows.
[tex]\frac{V_{1}}{T_{1}} = \frac{V_{2}}{T_{2}}\\\frac{1.90 L}{21.0^{o}C} = \frac{5.70 L}{T_{2}}\\T_{2} = 63^{o}C[/tex]
Thus, we can conclude that the new temperature is [tex]63^{o}C[/tex].

List and describe two differences between pure substances and mixtures. Check all that apply. Check all that apply. The composition of a pure substance depends on the source, but the composition of a mixture doesn't depend on the source. The composition of a pure substance is always the same, regardless of the source, but the composition of a mixture can vary. The state of a pure substance is always the same, but the state of a mixture can vary. Mixtures can be separated into their components only by chemical changes; some pure substances can be separated into components by physical change. Mixtures can be separated into their components by physical changes; some pure substances can be separated into components by chemical change.
Answer:
The composition of a pure substance is always the same, regardless of the source, but the composition of a mixture can vary.
Mixtures can be separated into their components by physical changes; some pure substances can be separated into components by chemical change.
Explanation:
A chemically pure substance has a well defined and constant composition. The composition of a chemically pure substance remains the same irrespective of its source. Also, the components of a chemically pure substance may be separated by chemical changes.
Mixtures have a variable composition depending on their respective sources. The composition of a mixture varies with the source of the mixture and mixtures are separated by physical processes.

What is the relationship between surface tension and Cohesion?
A. As cohesion increases, surface tension increases
B. As cohesion increased, surface tension decreases.
Answer:
A
Explanation:
Cohesion is basically the attraction of same molecules and surface tension occurs due to the attraction of molecules . Therefore as cohesion becomes high, surface tension becomes here. We can say then that Cohesion is directly proportional to surface tension

2. How many atoms of each element does a mole of Aspartame contain?
Answer:
The molecular formula for aspartame is C14H18N2O5, and its molar mass is about 294 g/mol. 1.2 g / 294 g/mol = 4.08 X 10-3 moles aspartame. Since each mole of aspartame has 2 moles of nitrogen, you have 8.16 X 10-3 moles of N in your 1.2 grams of aspartame.

Metal
Metalloid
Non-metal
Answer:
Metal
Non-metal
Explanation:
Ionic compounds are said to be formed when metals donate electrons to non metals.
The metals become positively charged while the nonmetals become negatively charged.
CaF2 is composed of Ca^2+ and F^-. Calcium is a metal of group 2 in the periodic table while F is a nonmetal of group 17 in the periodic table.
Hence CaF2 is composed of a metal and a nonmetal.

Answer:
I believe the answer is A (changes in air temperature result in differences in air pressure which causes wind). Hope this helps
Explanation:
Find the number of moles in:
12.044 x 10^24 atoms
Explanation:
number of moles = number of particle/ 6.02X10^23
= 12.044 X 10^24/6.02×10^23
=20.0066 moles so round it up to 3 S.F
So
=20.0moles

What reacts with the hydrocarbon fuel in a combustion reaction? small words, please
Hydrocarbon combustion refers to the chemical reaction where a hydrocarbon reacts with oxygen to create carbon dioxide, water, and heat.
#small words#The half-lives of both zero-order and second-order reactions depend on both initial concentrations and rate constants. Why does the half-life for second order decrease with increasing initial concentration
Answer:
This is because the half life of second order reactions is inversely proportional to the initial concentration of the reactant.
Explanation:
The equation to half life in the second order reactions is given by:
t1/2=1/[A]initial
From the equation, you can see that as the initial concentration of A increases the denominator also increases ,thus overall value (t1/2) decreases.
Hope this helps:)
