Answer:
Option C. Dicer
Explanation:
Dicer is a dsRNA endoribonuclease like bacterial Class III RNaseIII that is encoded by the DICER1 gene contains a N-terminal ATP-subordinate RNA helicase motif or domain.
Dicer cuts or cleaves precursor RNA molecules to make miRNA molecules. MicroRNAs regulates gene expression by hindering the procedure of protein creation. In the initial step of making a protein from a gene, another sort of RNA called RNA (mRNA) is made and goes about as the plan for protein production.
 
        
             
        
        
        
Answer:
Nine
Explanation:
These are called carrier proteins, and they have what it is called: solute-binding sites, that when saturated, they are considered "full".
Each different amino acid needs a separate carrier protein to move it across the plasma membrane, so that's 3, then the four different sugars need separate carriers as well, we add 4 more then, we have 7 so far, finally the 2 different ions use 2 more, plus the other 7, totals 9.
 
        
             
        
        
        
Scientists collect information that allows them to make evolutionary connections between organisms. Similar to detective work, scientists must use evidence to uncover the facts. In the case of phylogeny, evolutionary investigations focus on two types of evidence: morphologic (form and function) and genetic.

Answer and Explanation: The excretory system helps the respiratory system by getting rid of carbon dioxide. The respiratory system helps the excretory system by getting rid of CO2 from the body. They both need each other and if one or the other did not exist, we might've not been able to survive. Tis demonstrates how vital they are for the human body.
