Inside the stomach, Hydrochloric acid kills micro-organisms in the food. Stomach juices begin to break down <u>proteins</u> to amino acids.

✤ So, Fill the blank with proteins.

<h3><u>Explanation:-</u></h3>

Inside the stomach, the digestion of proteins starts due to the action of pepsin enzyme.
But this enzyme remains inactive and is activated by the Hydrochloric acid(HCl).
The Hydrochloric acid also helps in killing the germs and microbes which entered along with food.
The mucous lines the wall of stomach to protect it from the harm caused by HCl because HCl is a strong acid.
In stomach, The partial digestion of proteins occur and rest is digested in the small intestine by Trypsin(Pancreatic enzyme) and Intestinal juices.

The world's record in the 100 m dash is 9.69 seconds and in the 100 yard dash is 9.21 seconds.

Andrews [41]

Speed is equivalent to the distance traveled divided by the time it takes to travel that certain distance.
To solve this problem convert the units first from meter and yards to miles. 100 metes is 0.0621371mi and 100 yards is 0.0568182 yard. 9.69s = 0.002691667 hr and 9.21s = 0.002558333

A.) 23mi/hr
B.) 22.20mi/hr

Calculate the frequency required to eject electrons from gold with a work function of 8.76 x 10-19 J

Savatey [412]

$hf=W+\frac{mv^{2}}{2}\\\\
f=\frac{W+\frac{mv^{2}}{2}}{h}\\\\\

W=8,76*10^{-19}J\\
m=9,11*10^{-31}kg\\
v=3*10^{8}\frac{m}{s}\\
h=6,63*10^{-34}Js\\\\\\
f=\frac{8,76*10^{-19}J+\frac{9,11*10^{-31}kg*(3*10^{8}\frac{m}{s})^{2}}{2}}{6,63*10^{-34}Js}=7,5*10^{19}Hz$
