Do you think ants would be better than dogs at detecting disease

Chemistry

Verizon [17]2 years ago
6 0

Answer:

Ants are as good as sniffer dogs at detecting disease

“Ants are thus equivalent to dogs – the most studied bio-detectors in terms of detection abilities,” the researchers write.

Ants Have a Sense of Smell Better Than That of a Dog

Not bad for a creature that doesn't have an actual nose—you read that right. An ant's smell receptors are actually in its long antennae. This is important because smell is everything for ants

Snape grows tired of these conceptual questions and thinks it's time for a problem. What is the retention factor if the distance
MAVERICK [17]

Answer:

The Retention factor (rf) value is = 0.2

Explanation:

  • Retention factor (Rf) is factor used substances that could be separated using Chromatography. Retention factor determines how fast the component can move on the chromatogram (stationary phase) after elution. Elution occurs when mobile phase (solvent) moves across the stationary phase when the solute has been spotted on the origin.
  • Retention factor (Rf) ranges from value between 0 and  1. The closer the value to 1, the faster it can move upon elution. Rf can be calculated.
  • Rf value = distance moved by the solute / distance moved by the solvent

             = 0.40cm / 2.00cm

             = 0.2

When solutions of silver nitrate and sodium chloride are mixed, a precipitation reaction occurs. What mass of precipitate can be
Bas_tet [7]

Explanation:

The given precipitation reaction will be as follows.

        AgNO_{3}(aq) + NaCl(aq) \rightarrow AgCl(s) + NaNO_{3}(aq)

Here, AgCl is the precipitate which is formed.

It is known that molarity is the number of moles present in a liter of solution.

Mathematically,       Molarity = \frac{\text{no. of moles}}{\text{volume in liter}}

It is given that volume is 1.14 L and molarity is 0.269 M. Therefore, calculate number of moles as follows.

                    Molarity = \frac{\text{no. of moles}}{\text{volume in liter}}

                     0.269 M = \frac{\text{no. of moles}}{1.14 L}

                    no. of moles = 0.306 mol

As molar mass of AgCl is 143.32 g/mol. Also, relation between number of moles and mass is as follows.

               No. of moles = \frac{mass}{\text{molar mass}}

                   0.307 mol = \frac{mass}{143.32 g/mol}

                           mass = 43.99 g

Thus, we can conclude that mass of precipitate produced is 43.99 g.
