Answer:
I think the black ones are stomata or guard cells and they are attached on epidermis
Stomata is used for breathing and epidermis is the skin(outer layer) of plants

Answer:
This is because it is a selective antibiotic that, when entering the body, binds to the 50s subunit of bacterial ribosomes, thus causing the disruption of protein transcription of bacteria.
This drug does not stop the transcription of human proteins since bacteria and humans do not have the same ribosomes, therefore, humans or sick cells do not have the active site to which the drug binds.
Explanation:
This is because it is a selective antibiotic that, when entering the body, binds to the 50s subunit of bacterial ribosomes, thus causing the disruption of protein transcription of bacteria.
This drug does not stop the transcription of human proteins since bacteria and humans do not have the same ribosomes, therefore humans or host cells do not have the active site to which the drug binds.
Erythromycin falls into the macrolide family and is considered a drug that is bacteriostatic at low concentrations and bactericidal at very high concentrations.
The difference between these named terms is that one ends the life of the bacterium (bactericidal) and the other stops the bacterial metabolism preventing its possibility of increasing in number.
 
        
             
        
        
        
The answer to this question is pyruvic acid. 
This process is also known as the Embden-Meyerhof  or glycolytic pathway and is undoubtedly the most common pathway for glucose degradation to pyruvate in the second stage of catabolism. It is found in all major groups of microorganisms  and functions in the presence or absence of oxygen.  Glycolysis occurs in the cytoplasmic matrix of prokaryotes and eukaryotes.
The pathway as a whole is divided into two parts: The initial 6 carbon stage  and secondly, the 3 carbon stage.
One of the products, glyceraldehyde 3-phosphate,  is converted directly to pyruvic acid in a five step process.  
 
        
                    
             
        
        
        
Answer:
 5V
Explanation:
Given parameters: 
Resistance  = 100Ω
Current = 0.05A 
Unknown: 
Voltage  = ? 
Solution: 
The voltage is the force that drives current through a circuit. According to ohms law, it is related to current and resistance using the expression below; 
          V = IR 
 Insert the parameters and solve; 
     V = 100 x 0.05 = 5V
