Can I have the brainliest? 
positive impacts
Animals can be engineered to require less food, grow quicker, and leave behind less evironmentally damaging waste.
-Animals can be engineered to be more resistant to harmful and painful diseases.
-Animals can be engineered to produce more omega-3 fatty acids, to provide leaner meat, and to make more milk.
-Animals can be engineered so their tissues, organs, and cells can be transplanted into humans.
-Animals can be engineered to produce certain substances that offer a new source of medicine.
-Animals can be engineered to reproduce much faster.
negative impacts.
It is unethical.
-Some food companies have refused to use meat or milk that is from genetically engineered animals.
-Some consumers are complaining that the animal drug rules do not regulate genetically modified animals properly.
-This process is potentially dangerous and can be very harmful.
-When engineering animals the natural ecosystem can be disturbed.
-Some animals die in experiments while other are born deformed or huge.
-Animals may live in odd comditions that are affect their natural way of life.
-Most injected eggs do not end up creating a living animal.
        
             
        
        
        
B. Cell wall and a central vacuole
The cell wall is a rigid structure that surrounds the cells and allows plants to stay upright.  Animal cells are more fluid.
The central vacuole is a large region in the cell that stores nutrients and fluids.  Many cells, including animal cells, contain vacuoles, but most are small, and only plant cells contain large central vacuoles.
Hope this helps!!
 
        
             
        
        
        
1.) DNA replication is a process where the double helix is unwound and each strand is replicated to create another. This occurs in all replication of the body cells, or reproductive cells, a common process called mitosis.
2) The original DNA molecule is exactly the same as the replicated molecule, but the original is called the parent cell and the replicated molecule the daughter cell.
3) Enzymes act as catalysts/proofreaders of DNA replication. For example, Primase synthesizes RNA primer, or DNA ligase joins DNA strands together.
        
                    
             
        
        
        
Answer:
A cell is a mass of cytoplasm that is bound externally by a cell membrane. Usually microscopic in size, cells are the smallest structural units of living matter and compose all living things. Now put that into your own words.
