Answer 1

Answer:

Pepsin functions best in acidic environments and is often found in an acidic environment, particularly those with a pH of 1.5 to 2".

"Trypsins have an optimal operating pH of about 8".

It seems that the highest level of activity for the two if they were in the same environment would have to be midway between their optimum range - about pH 5

At what age is the difference between the average height of boys and girls greatest?Estimate this difference to the nearest centimeter.

Answers

Answer:

Sixteen years old is the age where the biggest difference between the average height of boys and girls can be observed. This is a difference of approximately 5.7 cm.

Explanation:

As we know, for biological reasons, boys and girls have different growths and different development in their bodies. However, the growth and development of boys and girls during childhood is very similar and only starts to look different even from adolescence, where individuals have great structural differences.

At 16 years of age, boys and girls have the greatest mean difference in height. While in previous years this difference was on average 1 centimeter, at 16 years old, girls are 150.8 cm tall on average, while boys are 156.5 cm tall.

Due to the average rate of growing starting to properly sprout at the age 11, surely those years around it would be the greatest difference.
I think there is about a 15cm difference on average.
