ACROSS: 2. Chemical used on skin .
Process in which proteins lose their three dimensional structure from the application of extreme heat
9. Mechanical filter for high-efficiency particulate air
10, Intermediate level disinfectants that are most effective at 70% to 90% strength.
DOWN:
1. Form of short wavelength ionizing radiation
3. Destruction of all microbes in or on an object.
4. Chemical used in the destruction of most microbes and viruses on inanimate objects.
5. Bisphenolic agent that was banned by the FDA in 2016.
6. Passage of fluid through a sieve designed to trap cells and viruses.
8. Agent that kills microorganisms, rather than inhibits it.

2. Antiseptics are the chemicals that are used on the skin like ethanol.  

Denaturation refers to the phenomenon in which proteins lose their 3-D composition due to the usage of high heat.  

9. HEPA filters are the mechanical filters that help in eradicating particles and microbes from the air.  

10. Alcohols are the intermediate level disinfectants that at the strength of 70 percent to 90 percent helps in disrupting cell membranes and denature proteins.  

1. Gamma radiation is a kind of short-wavelength ionizing radiation.  

3. Sterilization refers to the procedure in which the destruction of all kinds of microbes is done in or on an object.  

4. Disinfectants are the chemicals that have an application in eliminating the majority of viruses and microbes on the inanimate objects.  

5. Bisphenol A refers to a bisphenol agent that got banned by the FDA in 2016.  

6. Filtration refers to a procedure in which the fluid is permitted to pass through a passage, which is developed to trap viruses and cells.  

8. Cidal agent refers to the agent that eliminates microbes rather than inhibiting it.  

spiders belong to a group of arachnids.

arachnids have the following traits :

they have two body parts.

they have eight legs unlike insects which have 6 legs.

they have no wings.

these traits distinguish them from insects.

the information that antonio is doubting us the statement that spiders differences are as a result of being first to evolve.

this is because the evolution of one species is independent of the other species.

answer: substrate concentration. enzymes work best when there is a high enough substrate concentration for the reaction they catalyse.
