A researcher inserted the human gene for the protein hemoglobin into a plasmid. The plasmid was taken up by a bacterial cell through the process of transformation. The bacterial cell utilized the gene to produce a protein. However, the protein did not have the same amino acid sequence as hemoglobin has in a human cell. In fact, the protein in the bacterial cell was much longer than in the human cell. How can you explain this?

the abdomen (less formally called the belly, stomach, tummy or midriff) constitutes the part of the body between the thorax (chest) and pelvis, in humans and in other vertebrates. the region occupied by the abdomen is termed the abdominal cavity. the stomach secretes acid and enzymes that digest food. ridges of muscle tissue called rugae line the stomach. the stomach muscles contract periodically, churning food to enhance digestion. the pyloric sphincter is a muscular valve that opens to allow food to pass from the stomach to the small intestine.

"do a testcross with a homozygous recessive plant."

sheep is a herbivore animal whereas grasshopper belongs to the class chordates but both of them feed on greens.  

if grasshopper and sheep feeding on a pasture land, i do not think both of them will have any impact on each other. however, the number of the species can make difference. since sheep feed on greens, there is a possibility there left no pasture land for the grasshoppers or they may get extinct.
