Active transport: Movement of materials across a membrane that requires an input of energy from a cell. Movement of material against the concentration gradient (from low concentration to high concentration)
Passive transport: Movement of materials across a membrane that does not require energy from the cell. Movement of material against the concentration gradient (from high concentration to low concentration)
Hope this helps!
 
        
                    
             
        
        
        
all of the above can be considered ecosystems
 
        
                    
             
        
        
        
It should be C! (: Fate mapping because it is used do dermine tissue linage! 
While Differentiation is used when one cell type changes from one cell to another.
When it comes to the process an undifferentiated cell is already programmed to become a specific cell type by following a specified path towards cell differentiation. 
I hope all is well, and you pass! (: Good luck, rockstar! If you need any further information, let me know. (:
        
             
        
        
        
I think in real life because you get to see how they act and i have been on three trips i know that this is not related but I've been to Egypt and Italy and china and i am in 7th grade so ya. I think seeing animals and things in real life is the best thing to do overall.
 
        
             
        
        
        
Answer:
The function of  biomolecule inside our body system fully depends on the structure of that biomolecule.It is because the functional groups that participate in a  chemical or biochemical reactions are arranged in a specific array in the structure of that biomolecule or macromolecule.
Explanation:
a enzyme structure/catalysis    Enzymes are proteinecious in nature.Enzyme contain various amino acids in its active site such as histidine,serine,glutamic acid etc The amino acids of the active site of that enzyme interact with the substrate resulting in the formation of the product.
b mRNA structure/protein synthesis  mRNA or messenger RNA consist of nucleotide sequence.The 3 concequetive nucleotides of an mRNA is termed as codons.Each codon codes for specific amino acid.The so formed amino acid linked with the adjacent amino acid by peptide linkage.
c cell membrane structure and signal transduction cell membrane contain various surface protein that act as receptor to detect signals by binding with signaling molecule during signal transduction process.
