Answer:
b.  Capillaries; veins; arteries
Explanation:
Capillaries are the blood vessels with very thin walls. They serve as a site for an exchange of substances such as respiratory gases, nutrients, and toxins between the blood and the cells of the tissues. Veins are the blood vessels that mostly pick the deoxygenated blood from the body cells and deliver it to the heart for oxygenation. On the other hand, arteries are the blood vessels that mostly carry the oxygen-rich blood. They pick the oxygenated blood from the heart and deliver it to body cells. Therefore, veins carry blood towards the heart while arteries carry it away from the heart. 
 
        
             
        
        
        
Answer:
Human insulin 
Explanation:
The process where by region of a DNA that codes for a particular function is transferred between organisms into cells Is described as gene transfer. This process can be used to enhance the mechanism of producing a gene that is not originally present in such organisms before. Therefore if the gene that code for insulin is inserted into a bacterial vector , the offspring of such bacteria will be able to synthesize insulin in their cell
 
        
             
        
        
        
<span>Okay, so herbivores are animals that feed on plants, so in Finding Nemo, those would be Bubbles (a yellow tang), the turtles, and Dory (a blue tang). On the other hand, carnivores are all animals that eat meat in order to survive, so in this cartoon, those animals would be primarily the sharks: Chum (a maiko shark), Bruce (a great white shark), and Anchor (a hammerhead shark). </span>
        
             
        
        
        
The answer is Catecholamine. It is any of a class of aromatic amines that includes a number of neurotransmitters such as epinephrine and dopamine. The adrenergic receptors are a class of G protein-coupled receptors that are targets of the catecholamines, especially norepinephrine (noradrenaline) and epinephrine (adrenaline). These three - catecholamine, peptide hormones and eicosanoids acts as extracellular membrane receptors which means that these receptors are embedded in the membranes of cells. They act in cell signaling by receiving (binding to) extracellular molecules.
        
             
        
        
        
The way that does not successfully classify protists is their size. Thus, the correct option is C. 
<h3>What are Protists?</h3>
Protists may be defined as one of the diverse taxonomic groups and particularly a kingdom of eukaryotic organisms that are unicellular and sometimes colonial or less often multicellular and that generally include the protozoans, most algae, and often some fungi. 
On the basis of the way that Protists reproduce, they can be subdivided into three types: Sexually reproducing protists, asexually reproducing protists, and conjugation-based. 
On the basis of how protists get energy and food, they are again subdivided into three categories. 
- Animal-like protists: Heterotrophs that have the ability to move.
- Plant-like protists: Autotrophs that have the ability of photosynthesis. 
- Fungi-like protists: Heterotrophs have cells with cell walls. 
On the basis of the way that they move, they are subdivided into two types: Motile protists and non-motile protists. They generally move with the help of cilia, flagella, and pseudopodia. 
Therefore, the size is not one of the following ways that protists are grouped. Thus, the correct option for this question is C.
