Answer:
<h2>Apoenzyme
</h2><h2>Cofactors</h2>
Explanation:
Conjugated enzymes also known as holoenzyme. Simple enzymes consist of only protein alone  but  the Conjugated enzymes contain protein ( this portion is called Apoenzyme) and nonprotein molecules (this portion is called cofactor). Cofactor help enzymes in their action.
Enzymes are catalyst which increase the rate of a reaction by decreasing the activation energy.
 
        
                    
             
        
        
        
Answer:
the correct answers are as follows
12:
b. Testcross- an organism with dominant phenotype but unknown genotype is crossed with homozygous recessive organism for the same trait. Based on the results obtained, if all offsprings have the same phenotype, then the parent is homozygous, but when a 1:1 ratio is observed in the offsprings, then the parent is heterozygous.
13.
e. Watson and Crick- they both used the crystallographic images from Franklin, analyzed them to first elucidate the 3D structure of the DNA and propose it to the world.
14.
c. Intracellular and commonly found in the cytoplasm- the receptors of steroid hormones are generally present within the target cell either in the cytoplasm or nucleus, since they alter gene expression.
15
e. Certain prokaryotes/bacteria- this is a process that will enable disease-causing pathogens to communicate and cooperate with their group, by the release of autoinducers that increase their cell density.
 
        
             
        
        
        
Answer:
This are our options to complete the question
-bottom-up and top-down hypotheses
-competitive exclusion
-keystone species
-resource partitioning
-character displacement
The CORRECT ANSWER IS resource partitioning.
Explanation:
Resource partitioning is the division of certain limited resources by species to eliminate competition in an ecological niche in order to allow easy coexisting with one another
The creeper searches for insects by hunting from the bottom of the tree trunk to the top, whereas the nuthatch searches from the top of the trunk down to eliminate competition and allow for peaceful coexisting between them

Answer:
This observation is True
Explanation:
Membrane integral proteins can function as ion channels during the transport of molecules through the membrane. Moreover, integral proteins can also act as pores for the transport of specific molecules between both sides of the membrane, ion channels that mediate effector signals, signaling transduction mechanisms capable of amplifying cellular responses and hormone receptors.
