0.5 hour=30 minutes
0.75 hour=45 minutes
30*3=90 minutes
45*2=90 minutes
90+90=180 minutes
Remember, there are 60 minutes in 1 hour.)
180 minutes/1 hour=3 hours
So: Emma reads for 3 hours each week.
hope this helps! <3
Adenine pairs with Thymine (A=T) AND Cytosine pairs with Guanine (C=G)
The hypothesis which most likely explains the results is The enzyme breaks down at temperatures above 60°C; option B.
<h3>What are enzymes?</h3>
Enzymes are biological catalysts which speed up the rate of chemical reactions that occur in the body.
Enzyme activity is affected by the following factors:
- temperature
- pH of the medium
The temperature at which enzyme works best is known as optimum temperature.
The pH at which enzyme works best is known as optimum pH.
Considering the results of the experiment as shown in the graph:
The activity of the enzyme decreases to zero at 60°C.
Therefore, the hypothesis which most likely explains the results is The enzyme breaks down at temperatures above 60°C; option B.
In conclusion, enzymes are denatured by high temperatures.

REMEMBER: color blindness is carried on the X chromosome only! The male has to inherit the mutated gene from his mom and her X chromosome to be color blind. Because the male has only 1 X, he has a greater chance to be color blind than a daughter who would have to inherit a bad X chromosome from each parent!
If you follow the family tree, the person 12 (the daughter of 4x5) could be either XX or XX (I'm using bold to indicate the color blind gene on the X chromosome). You cannot tell from this family tree what she is (except that we know her mom (4) is definitely a carrier!
So you need to do two potential crosses:
1. Daughter 12 is not a carrier; so she is XX
Cross XX with XY; you get the possibility of all daughters as carriers XX, or all normal sons XY.
2. Daughter 12 is a carrier; so she is XX
Cross XX with XY; you get the possibility of daughters that are color blind (XX), daughters as carriers (XX), color blind sons (XY) and normal sons.
Answer:
So people know that everything has a value and they should appreciate it.
