How the does the shape of an enzyme affect the reaction?

Answer: Enzyme has an active site in a particular unique shape which a substrate recognises and bind to.

Explanation: For a reaction to occur, all enzymes have an active site that a specific substrate will bind to forming an enzyme-substrate complex, then a required product is created. Due to this, sometimes a reaction may not occur because of inhibition. Enzyme inhibition is caused by having a molecule with a conformation that resembles a subtrate, the molecule or substance will compete with the substrate for the enzyme active site preventing a reaction to take place. Inhibition may either be competitive as described above or non-competitive where a substance will not directly bind to the active site but will change the conformation of the enzyme in a way that a subtrate will not be able to bind.

Answer:

(b) The interquartile range of B is greater than the interquartile range of A.

(d) The median of A is the same as the median of B.

Explanation:

Given

$A = \{1, 4, 2, 2, 3, 1, 1, 2, 1\}$

$10th\ run = 9$

So:

$B = \{1, 4, 2, 2, 3, 1, 1, 2, 1,9\}$

Required

Select all true statements

(a) & (d) Median Comparisons

$A = \{1, 4, 2, 2, 3, 1, 1, 2, 1\}$ $B = \{1, 4, 2, 2, 3, 1, 1, 2, 1,9\}$

$n = 9$ $n = 10$

Arrange the data:

$A = \{1, 1, 1, 1, 2, 2, 2,3, 4\}$ $B = \{1,1,1,1,2,2,2,3,4,9\}$

$Median = \frac{n + 1}{2}th$

$Median = \frac{9 + 1}{2}th$ $Median = \frac{10 + 1}{2}th$

$Median = \frac{10}{2}th$ $Median = \frac{11}{2}th$

$Median = 5th$ $Median = 5.5}th$ --- average of 5th and 6th

$Median = 2$ $Median = \frac{2+2}{2} = 2$

Option (d) is correct because both have a median of: 2

(b) & (c) Interquartile Range Comparisons

$A = \{1, 1, 1, 1, 2, 2, 2,3, 4\}$ $B = \{1,1,1,1,2,2,2,3,4,9\}$

$n = 9$ $n = 10$

First, calculate the lower quartile (Q1)

$Q_1 = \frac{n + 1}{4}th$ [Odd n] $Q_1 = \frac{n}{4}th$ [Even n]

$Q_1 = \frac{9 + 1}{4}th$ $Q_1 = \frac{10}{4}th$

$Q_1 = \frac{10}{4}th$ $Q_1 = 2.5$

$Q_1 = 2.5th$

This means that:

$Q_1 = 2nd + 0.5(3rd - 2nd)$ $Q_1 = 2nd + 0.5(3rd - 2nd)$

$Q_1 = 1 + 0.5(1- 1)$ $Q_1 = 1+ 0.5(1 - 1)$

$Q_1 = 1$ $Q_1 = 1$

Next, calculate the upper quartile (Q3)

$Q_3 = \frac{3}{4}(n + 1)th$ [Odd n] $Q_3 = \frac{3}{4}(n)th$ [Even n]

$Q_3 = \frac{3}{4}(9 + 1)th$ $Q_3 = \frac{30}{4}th$

$Q_3 = \frac{30}{4}th$ $Q_3 = 7.5th$

$Q_3 = 7.5th$

This means that:

$Q_3 = 7th + 0.5(8th- 7th)$ $Q_3 = 7th + 0.5(8th- 7th)$

$Q_3 = 2 + 0.5(3- 2)$ $Q_3 = 2+ 0.5(4 - 2)$

$Q_3 = 2.5$ $Q_3 = 3$

The interquartile range is $IQR = Q_3 - Q_1$

So, we have:

$IQR = 2.5 - 1$ $IQR = 3 - 1$

$IQR = 1.5$ $IQR =2$

(b) is true because B has a greater IQR than A

(e) This is false because some spread measures (which include quartiles and the interquartile range) changed when the 10th data is included.

The upper quartile and the interquartile range of A and B are not equal

Petra finds a discolored stain on the carpet at a suspected crime scene. What two presumptive tests might she use to determine i

german

Answer:

First, Petra sprays the discolored area with

Fluorescein

, which returns a glowing blue color. However, she knows that this chemical might also turn blue with other substances that contain iron. Subsequently, she uses

Phenolphthalein

, which turns pink, indicating the presence of hemoglobin.

How does prokaryotic DNA differ from eukaryotic DNA? I. Prokaryotic DNA lacks nucleosomes. II. Eukaryotic DNA has telomeres. III

Archy [21]

Answer: Ii. Eukaryotic dna has Telomeres.

Explanation:

Deoxyribonucleic acid is a substance that has double helix coil and contain the genetic material . DNA differ in prokaryotic and eukaryotic cell. Prokaryotic cells have no membrane bound nucleus while eukaryotic cells have membrane bound nucleus.

Prokaryotes DNA is found in the cytoplasm and the eukaryotes DNA is found in the nucleus.

Prokaryotes DNA lacks telomere while eukaryotic DNA have Telomeres. Telomeres is a specialized dna cap that consist of hundred or thousands of DNA repeats. It prevent loss of Gene.
