The researcher wants to investigate whether carpet makes a difference in the mean bacterial concentration in air. the null and alternative hypotheses would be:
H0: The mean of the carpeted rooms = the mean of the uncarpeted rooms
Ha: The mean of the carpeted rooms ≠ the mean of the uncarpeted rooms
The attention of bacteria majorly depends on the awareness of inoculum, incubating temperature, and the metabolic country of inoculated pressure used. The bacterial concentration suspended in growth media may be calculated.
In idea, you could listen to cells through filtration or centrifugation, but likely no greater than a hundredfold. for your case, you're asking to concentrate by 10,000 fold. So you sincerely might want to develop denser cultures of cells. You can centrifuge your modern broth and resuspend the pallet in a clear broth.
In microbiology, the minimal inhibitory attention (MIC) is the lowest concentration of a chemical, generally a drug, which prevents the visible boom of a bacterium or bacteria.

Answer:
B. French wines will become more expensive in the United States.
Explanation:
Exchange rate is the rate at which one currency can be exchanged for another during international trade. The strength of a currency determines how much of the other countrie's goods it can purchase.
When the strength of a countrie's currency is high it will purchase more of the other countrie's goods. If however the currency is weak, it will take more to buy the other countrie's goods.
In this case if the dollar falls against the euro, it will take more dollars to buy French wine than before.
For example if a bottle of French wine was $500, after the fall the price may now be $800.

Answer: Resellers
Explanation:
Resellers buy products from other businesses but do not significantly alter the form of the products they buy before selling them.
A reseller is a type of channel partner that acts as an intermediary between companies that make, distribute or provide IT products or services and end customers, which may be businesses or consumers. A key reseller role has been order fulfillment: The customer goes to a reseller to simplify the ordering process and offload procurement and order processing tasks.
Working with a reseller can also streamline product sourcing. A business that needs to purchase multiple technology components can make those purchases through a single reseller versus approaching multiple manufacturers or service providers directly. Competitive pricing may also attract customers to resellers.
