Brilliant_brown [7]

Answer:

To determine the effect of toxin binding, you perform a Competitive Binding Experiment

Explanation:

Competitive binding experiments are very relevant when matters relating to cellular and or molecular toxicity are concerned.

They are used to determine the binding of a single concentration of labeled ligand in the presence of various concentrations of unlabeled ligand.

They are important because:

1. Validate a direct binding assay

2. Confirm whether or not a drug binds to the receptor

3. determine and explore how low-affinity drugs and receptors interact and it's resultant effects

When studying animal behavior, the distribution of organisms within a choice chamber can be studied to identify animal preferenc
Komok [63]

Answer:

c

Explanation:

Random distribution of the Isopods should be 50/50 in A and B.

Chi-square = \frac{(O - E)^2}{E} where O = observed frequency and E = expected frequency

Chamber         O                    E             Chi-square

  A                   18                   10             \frac{(18 - 10)^2}{10} = 6.4

  B                    2                    10             \frac{(2 - 10)^2}{10} = 6.4

<em>Total Chi-square </em>= 6.4 + 6.4 = 12.8

<em>Degree of freedom</em> = 2 - 1 = 1

<em>Tabulated Chi-square</em> (α = 0.05) = 3.8415

The calculated Chi-square exceeds the critical value, hence, it is significant and not due to random.

<em>The correct option is </em><em>c</em><em>.</em>
