Answer:
B. sending neurotransmitters to endocrine target cells
Explanation:
Your endocrine system works closely with your brain and central nervous system to control the creation of specific hormones and enzymes.
 
        
             
        
        
        
Answer:
a. PK2 activates PK1
b. no response would be produced
Explanation:
Kinases are enzymes known to phosphorylate different substrates, thereby activating/inactivating them. In this case, a mutation that produces a constitutively (permanently) active PK1 kinase is itself able to continue the signaling pathway, independently of whether or not PK2 is present. This constitutive mutation shows that PK1 is recruited to continue signaling events within the cell and, therefore, PK1 activation is downstream in the signaling pathway. Conversely, cells containing active PK2 and inactive PK1 would be unable to continue the signaling pathway since PK2 activation is upstream of the induction of PK1, and thereby these cells cannot respond to the signal (PK2 activation).
 
        
             
        
        
        
Answer:
Respiration occurs when glucose (sugar produced during photosynthesis) combines with oxygen to produce useable cellular energy. This energy is used to fuel growth and all of the normal cellular functions.
 
        
             
        
        
        
The correct answer is C. 
(The nonspecific response provides an immediate response, while the specific response involves a delay between exposure and response.)
 - The non-specific immune response is the first line of protection from different types of pathogens and microbes such as skin (physical barrier). It is immediate response however, it is not specifics and it does not involve the recognition of pathogens.
- The specific immune response depends on pathogen recognition and therefore is long-lasting immunity and it takes time to be effective. This response includes B- cells, T-cells, phagocytic cells and NK cells.
