Answer:
Using the host's cellular metabolism, the viral DNA begins to replicate and form proteins. Then fully formed viruses assemble. These viruses break, or lyse, the cell and spread to other cells to continue the cycle. Like the lytic cycle, in the lysogenic cycle the virus attaches to the host cell and injects its DNA.
 
        
             
        
        
        
Answer:
controlled the fertilization process.
Explanation:
Mendel took precautions to avoid contamination by pollen through self pollination of the P generation. He controlled the fertilization processes between the plants. He self pollinated the first pureline varieties to form the P generation. He then cross pollinated them to get F1 generation. Every step of his experiment was controlled.
 
        
             
        
        
        
Answer:
Radioactive labeling is a procedure used to monitor the path followed by a chemical element within  a biological system to demonstrate the source.
Hypothesis: 
The free oxygen produced during photosynthesis comes from water.
Procedure.
Single-celled algae were placed in four petri dishes containing carbon dioxide, glucose dissolved in  Water. 
In each box the oxygen was radioactively marked.
1 petri dish with CO2 marked. Experimental groups
2 petri dish with H2O marked. Experimental groups
3 petri dish with Glucose marked. Experimental groups (control)
4 petri dish with CO2 + H2O + Glucose, all marked. (control).
 
        
             
        
        
        
1.) B it is not d because it shows a growth in the beak size, it didn't say anything about the birds having larger beaks just that the size increased
2.) A
p=.5 q=.5
q^2=.25 p^2= .25 2(pq)= .5  everything added up is 1.0 so we good
so q^2, which is the recessive gene or gg, is 25 percent
