Answer:
True
Explanation:
Milipedes belong to a class of organism known as diplopoda which have double foot. Thus, millipedes have two legs per segments. They usually have  two pairs of jointed legs. The double legged segments have formed out of two single segments fused together
 On the other hand ,  a centipedes has  only one pair of legs per segment. 
Thus the given statement is true. 
 
        
                    
             
        
        
        
Answer:
The correct answer is through anaerobic respiration in the cytoplasm.
Explanation:
Cellular respiration is of 2 types 
1 Aerobic respiration  Respiration that require oxygen to occur
2 Anaerobic respiration Respiration that do not requires oxygen.
During low oxygen level the body of runner keep up with the demand for energy by undergoing anaerobic respiration which includes Glycolysis.
   During anaerobic condition the functionally active body cells undergo glycolysis and with each glycolysis 2 molecules of ATP are generated which can some how boost the energy supply within runner"s body.
    
 
        
             
        
        
        
It should be the last one, but if you can pick more than one answer then I would do the first and last one but I’m confident that it would be the last one either way :) hopefully this is helpful
        
             
        
        
        
Answer:
A. Lancelet
B. All chordates
Explanation:
A. Dorsal nerve chord is the only <u>unique feature</u> among all members of <u>phylum chordata</u> (mainly found in subphylum Vertebrata). In the given list, only lacelet is the Chordate whereas <u>snail belongs to phylum Mollusca</u>, <u>grasshopper belongs to Arthropda</u>, and <u>jellyfish belongs to Cnidaria</u>. Dorsal nerve cord runs along the length of organism's body.
B. <u>Gill slits</u> are <u>opening structures</u> to gills through which water passes from pharynx/throat to exterior. Their main purpose is to help filter the food particles available in surrounding water. Although they are typical for amphibians and fishes, chordates also possess gill slits at embryonic stages. 
 
        
             
        
        
        
Option C:
B. wild-type 5-AUGCAUACAUUGGAGUGA-3 mutant 5'-AUGCAUACAUCUGGAGUGA- 3' 
Explanation:
A frameshift mutation is a genetic mutation such that the triplet nature of gene expression by codons, the insertion or deletion occurs in such as way that it alters the complete sequence of 3 codon sets and can change the reading frame, resulting in a completely different translation from the original.
As it is pertinent to understanding that all genes are normally translated in sets of 3 codons, which typically describes and explain a unique amino acid sequence. Thus, if a frame shift mutation occurs, it can affect many amino acid sequences and finally the entire protein.  
If we look at option B:
wild-type 5-AUG   CAU  ACA  UUG  GAG  UGA-3  
mutant 5’-    AUG   CAU  ACA  UCU  GGA  GUG  A-3’  
An insertion of a base Uracil showed at the end of 3rd codon which affected and altered the whole sequence of codon triplets. This changed all next codons and finally all next amino acids will be altered.
