Answer:
The correct option is: begins the hydrolysis of proteins in the stomach
Explanation:
Pepsin is a protease enzyme that is <u>synthesized by the stomach</u>. It is the main gastric enzyme that helps in the <u>digestion of proteins molecules </u>present in the food.
The pepsin enzyme catalyzes the<u> acid hydrolysis of the peptide bond in the proteins</u> at a very<u> low acidic pH of 1.5-2.0.</u>
This enzyme becomes <u>inactive at pH 6.0</u> and gets <u>fully denatured or irreversibly inactivated as the pH increases to 8.0</u>.
Explanation:
(c) I assume we're looking for mA.
Sum of forces on B in the -y direction:
∑F = ma
mBg − T = mBa
Sum of forces on A in the +x direction:
∑F = ma
T = mAa
Substitute:
mBg − mAa = mBa
mBg − mBa = mAa
mA = mB (g − a) / a
Plug in values:
mA = (5 kg) (10 m/s² − 0.01 (10 m/s²)) / (0.01 (10 m/s²))
mA = 495 kg
The answer key seems to have a mistake. It's possible they meant mB = 1 kg, or they changed mB to 5 kg but forgot to change the answer.
Answer:
Explanation:
Speed of an object is defined as the ratio of the distance covered by the object to the time taken to cover that distance.
Let 
be the speed of the object.
Let 
be the distance travelled by the object.
Let 
be the time taken by the object.
So,
s=
So,the speed of the car is 
Answer:
The Challenges of Using Natural Resources
Extracting, processing and using natural resources can cause environmental problems such as: air, land and water pollution; disruption or destruction of ecosystems; and a decrease in biodiversity.
