Gram's iodine reagent must be added to the plate before examination of amylase production.
Explanation:
The starch hydrolysis test is conducted to test the presence of the enzyme amylase in the test medium.
These are confirmatory lab tests done to detect and identify the presence of bacteria which can hydrolyze starch like amylose with the help of enzymes like amylase.
The test medium for this test is agar medium in a petri dish, where soluble starch is first added to initiate the microbial growth. Once incubation period of the microbes is over, dilute iodine solution is added to the petri dish in increased quantity. Iodine is a dye which helps to clearly identify the areas which are hydrolyzed by amylase and those which are not with the help of its color.
Because nonrenewable resources are diminishing in number, they will eventually become scarce, posing a variety of life dangers in the future.
<h3>
What are Non-renewable resources?</h3>
Nonrenewable resources are defined as substances that are depleted faster than they can be replaced.
Renewable resources are abundant, and capturing them is a sign of new life on the horizon. It is necessary to decrease your reliance on nonrenewable resources. As we saw during the corona pandemic, most countries' economies are progressively deteriorating. It also has an impact on one's quality of life. As a result, it must be stated that the world population will decline in the twenty-second century.

Answer:
Argon's atoms have 18 protons, 22 neutrons in its nucleus, orbited by 18 electrons- its atomic mass= P 18 +N 22.
Explanation:
Atoms are the most basic unit of matter that makes up elements. Atoms are composed of electrons orbiting neutrons and protons surrounding a nucleus.
The atomic number is defined as the number of protons in an atom, while the atomic mass is the number of protons and neutrons.
The element Argon, Ar is a noble gas, that exists in a gaseous, inert, state at temperature. Its atoms have 18 protons, 22 neutrons in its nucleus, orbited by 18 electrons- its atomic mass= P 18 +N 22.
There are 8 valence electrons in its outer shell, thus:
- Ar is not very reactive, as it does not require electron sharing in atomic bonding.
- It shows low conductivity, as there are no free electrons
Answer:
Curry contains turmeric powder and soap is basic in nature. ... Hence, when soap (which is basic in nature) is scrubbed on the stain, the stain turns red. When the cloth is washed with plenty of water, the soap is removed and the yellow colour of the stain reappears.
