Answer:
mitochondria: <u>powerhouse of the cell</u>
 Ribosomes<u>: the places where proteins are synthesized in our cells. </u>
nucleus <u>houses DNA;controls cell</u>
Vacuole: <u>holds waste and fluids from cell</u>
Ribosomes: <u>tiny organelles that contain RNA and specific proteins within the cytoplasm. </u>
Explanation:
Organelles make up the subunits of a cell.  There are numerous each with their own function.  
 
        
             
        
        
        
Answer:
The correct answer is BB genotype and BO genotype.
Explanation:
The human blood system or ABO system shows codominance due to the multiple alleles. That means three different alleles for human blood type are present are IA, IB, and i. For easy understanding can be stated as A (for IA), B (for IB), and O (for i).
If someone has blood type B could have a genotype of either BB or BO because of the dominance of B allele on O where is If A allele present with B allele it would show co-dominance.
Thus, the correct answer is the BB genotype and BO genotype.
 
        
             
        
        
        
Answer:
an Abiotic Factor
Explanation:
The non-living components of the environment are known as abiotic factors. Abiotic factors include things such as rocks,water,soil,light,rocks etc...
 
        
             
        
        
        
Answer:
they are Na+, K+ and Ca2+ ion channels.
Explanation:
Ionotropic acetylcholine receptors are also called nicotinic acetylcholine receptors because beside acetylcholine (Ch) they respond to nicotine. These receptors are  primary receptors in muscle for motor nerve-muscle communication that controls muscle contraction.
Two molecules of ACh are required for receptor to open. Since the receptors are  linked to ion channels, the channels open. Opening of the channel allows positively charged ions to move across it: sodium enters the cell and potassium exits.
 
        
             
        
        
        
The substance that would be added in order to reverse the reaction would be any substance that is found in the product side. Adding a substance that tends to be a product will shift the equilibrium of the system and will allow the reaction to produce the substances that is found in the reactant side.
