A period in 24-point font (.) is about 1mm in diameter. SARS-CoV-2 has a diameter of 80 nm. The prefix “milli” means 1000, which

tells you there are 1000 millimeters (mm)in a meter. The prefix “nano” means 109 (1 billion), which tells you there are 1 billion nanometers (nm) in a meter. Approximately how many SARS-CoV-2 viruses could fit in that period? (Hint: There are 106nm in 1mm).

Answer:

Approximately 12,500 SARS-CoV-2 viruses

Explanation:

According to this question, the period described is 1mm in diameter. Since 1millimetre(mm) is 1000metre(m), this means that the period is 0.001m in diameter.

Also, the SARS-CoV-2 virus has a diameter of 80 nm (1nm = 10^9m).

Since 10^6nanometres (nm) or 1,000,000nm makes 1millimeter (mm), 80nm of the virus will be:

= 80/1,000,000

= 0.000080mm or 8 × 10^-5mm

To calculate how many of the SARS-CoV-2 virus will fit into the period, we divide the diameter of the period (in mm) by the diameter of the virus (in mm).

That is; 1 ÷ 8 × 10^-5

= 1/8 × 10^5

= 0.125 × 100,000

= 12,500

Therefore, approximately 12500 SARS-CoV-2 viruses will fit in the period.

What can people do to stop the creation of more antibiotic resistant bacteria?
Allushta [10]

Answer:

Antibiotic resistance occurs when bacteria do some variation in their genome that allows bacteria to eliminate the effect of antibacterial drugs. Irregular or excessive antibiotics use is the main cause of generating antibiotic resistance bacteria.  

So antibiotics should be taken only on the prescription of doctors and a complete course of antibiotics should be done to eliminate all the bacteria so that no bacteria is left to generate antibiotic-resistant bacteria.

Antibiotics should be avoided in viral infection as antibiotic does not kill viruses as it is only beneficial in bacterial infection.

Evidence for evolution includes the presence of _______________________, which are similar structures shared by different specie
Ann [662]
The answer is <span>d. homologous structures.

Homologous structures are </span><span>similar structures shared by different species. For example, the anatomy of joints in bones of birds and dinosaurs, support the idea that these two groups have a common ancestor. But since these two groups are different enough to be separated into different classes, it can be concluded that they evolved from the common ancestor.</span>
