There were more substrate molecules to bond with the active site of the catalase enzyme as the substrate concentration increased.
<h3>What is an enzyme?</h3>
The enzymes are the chemical molecules that alter the chemical reaction when added in a specific amount, it either increases the reaction, or decrease it.
There were more substrate molecules to bond with the active site of the catalase enzyme as the substrate concentration increased.
Because the substrate concentration increased each time, there was a greater chance that the substrate would bind to the active site and carry out the reaction.
Thus, this way the enzyme concentration affects the reactivity.

<u>Answer:</u>
Geologists have sorted earth’s history into different geologic time scale. They just clubbed it into time scales by observing the major changes in the life forms that existed on the earth. Inferring to the fossils found in rocks the time scale was calculated.
First era single cell animals were formed then formed the complex animals.Then Mesozoic era where it is known as the era of dinosaurs. Then the evolution of different species of life during Cenozoic era. These major changes found through fossils helped them to form the GTS.
Elements of the periodic table in the same column, also known as a group, have similar chemical properties.
Oxygen is in the 16th column, or the 16th group.
The elements in the 16th group are known as c<span>halcogens.
The c</span>halcogens are oxygen (O, atomic number: 8), sulfur (S, atomic number: 16), selenium (Se, atomic number: 34), tellurium (Te, atomic number: 52), <span>polonium (Po, atomic number: 84), and livermorium (Lv, atomic number: 116), previously known as </span><span>ununhexium.
</span>
Possible answers:
Sulfur (S)
Selenium (Se)
Tellurium (Te)
Polonium (Po)
Livermorium (Lv)
Any three of these will work, since they are all in the same group as oxygen, and therefor have similar chemical properties to oxygen.
Hope this helps!
Irregular galaxy
A galaxy that has an unidentified shape is best classified as an irregular galaxy.
An irregular galaxy is a galaxy that has an undefined regular shape. These galaxies are composed of large amounts of young stars, gas, and dust. Irregular galaxies are usually small, disorderly in appearance, and without a nuclear bulge or any trace of spiral arm shape. Examples of irregular galaxies are the small and large magellanic clouds.
