root hair cell absorbs nitrates ions . remeber startch is CHO and protein is CHON . nitrates ion is carried in xylem to leaf where is combines with glucose to make protein CHO + N = CHON . protein is then transportted as ammino acid to rest of cell to be used for growth and repair . hope this helps

Genetic enginering is removing gene from speceis then add it to another
Bacteria has a special strand of DNA called plasimd this which makes is speacial .
lets say we want to modifly a plasmid to make insulin....
fist we need to take a gene from a organism which makes insulin (specific gene which codes for insulin production
then we need to extract the plasmid out of bacteria then cutting a gap through the plasmid using restriction enzyme ( cutting enzyme)
then we add the gene which produces insulin to gap then using a sticking enzyme we attach gene to plasmid .
place modified plasmid back into a new bacteria
place bacteria to grow in feminter and produce insulin .
hope this help . please tell what u think about answer.....

it is when humans select speceis with the charactaristics they want or need to breed together to make a combination of the charateristic they want .
so for example a fast horse and a strong horse when u breed them offspring is fast and strong (simple example)
hope this helps
