I think that I might be HYENA.
Since they don’t really kill they are mostly “scavengers” 
I am not 100% sure though. I hoped I helped at least a little.
        
             
        
        
        
Answer:
Vertebrates are further classified according to several criteria like exoskeleton, respiratory organs, method of giving birth, number of chambers in heart, mode of living etc. They are further classified into classes Pisces, Amphibia, Reptilia, Aves and Mammals
 
        
             
        
        
        
Answer:
What the scientist is doing incorrectly is hitting a rock with a hammer without protective equipment and on the same table where containers with chemical or biological substances are found.
Explanation:
Biosafety is an important aspect of laboratory work. Conducting studies in rocks, trying to fracture them with the use of a hammer is an incorrect practice carried out by a scientist when he does not use protective equipment and has containers with substances on the same work table.
<h3>what could he do to make their work in the lab safer?</h3>
- <em>Wear gloves, protective apron and protective eyewear.</em>
- <em>Break the rock on a work table where there are no containers that could break by accident, spilling their contents.</em>
<h3>why is it important to follow these procedures?</h3>
It is important to follow these procedures because injuries to hands, body or eyes can be avoided by fracturing the rock. In addition, it prevents the breakage of containers with chemical or biological products, which could contaminate the work area or cause damage to the scientist.
 
        
             
        
        
        
Answer: transcription
Explanation: Transcription is a process by which an mRNA is synthesized using a DNA template. It is the process of copying the genetic message encoded in a DNA into an RNA. This process is catalyzed by an enzyme known as RNA polymerase. The RNA polymerase requires a DNA template, four oligonucleotides (ATP, UTP, CTP, and GTP) as precursors for RNA synthesis. The newly synthesized mRNA is complementary to the template strand of DNA in the sense that wherever adenine is found in the DNA template strand uracil occurs in the mRNA strand, wherever thymine occurs in the DNA template strand, adenine is found in the mRNA strand and wherever guanine occurs in the DNA template, cytosine occurs in the mRNA strand.
