The graph illustrates the activity level of three common digestive enzymes, across a range of pH values. Which enzyme is likely to be active in the acidic environment of the stomach?A)
pepsin
B)
trypsin
C)
amylase
D)
pepsin and trypsin

Answers

Answer: A) Pepsin

Explanation: Acidic solutions are solutions which provide H^+ ions .More is the H^+ ion concentration, more acidic is the solution.

pH of a solution is defined as negative logarithm of H^+ ions concentration.

$pH =- log{[H^+]}$ or

$pH = log(1)/([H^+])$

Thus lesser is the pH,more is the H^+ concentration and more acidic is the solution.

Thus acidic solutions have low pH and pH ranges from 1 to 7 for acidic solutions.

As can be seen from the graph, enzyme pepsin has highest activity at low pH which means in acidic solutions. As the pH is increasing or the solution is turning basic, the activity of pepsin decreases.

I think amylase as well

How are the alleles for sex-linked traits inherited? They are passed from the Y chromosome in parents to the X chromosome in offspring. They are passed from the X chromosome in parents to the XY chromosome in offspring. They are passed from parents to offspring on the X and Y chromosomes. They are passed from any chromosome in the parents to the X or Y chromosome in the offspring.

Answers

Alleles for sex-linked traits are inherited in such a way that they are passed from parents to offspring on the X and Y chromosomes.

Generally, sex-linked traits are traits or genes that are found on the sex chromosomes only. In humans, females have XX sex chromosomes while males have XY sex chromosomes.

Thus, X-linked traits are passed from parents to offspring via the X chromosomes only. Since both males and females have X chromosomes, it means both genders can have X-linked traits.

Y-linked traits are passed from parents to offspring via the Y chromosomes only. Since only males have Y-chromosomes, it means that only the male gender can have Y-linked traits.

they are passed from parent to offspring on the X and Y chromosomes
