Biotechnology is science which uses biological processes in order to produce useful products or organisms with desired trait or characteristics.

It includes the manipulation of the genome of an organism.  

It helps in making products like insulin and genetically modified plants such as Bt cotton, golden rice et cetera.

However, it has many serious drawbacks as it includes the manipulation of the genome of an organism.

It can result in the development of resistant microorganism, for example, development of the superbug due to overuse of antibiotics.

Similarly, it can result in the production of toxic materials.

Thus, option d. all of the above would be the correct answer.

relationships aren't everything. people everyday spend there entire life depending on reltionships and for someone to be there for them when this is absurd. why must people depend on someone else to bring them happiness? i'm not saying it wrong to feel happy with someone, but people feel that they need to be in a relationship in order to feel happy, when, this is not true. you can paint, write, read ir slend tume with family ir even spend time working in yourself. this can be an exciting experience to find yourself. it's bot wrong to be in a relationship but if you let it be your only source of happiness, than you will never find true happiness.

so, relationships are not always worth it. if you are so dependent on them, than in the end they arent worth it because you will realize how unhappy you really were. some people even tend to cut ties with family because they think they cabt make them happy, obly realtionships with a lover can. false. in order to find true happiness, one must learn to love themselves if they want to love someone else. it's unhealthy to be always depend on relationships and to alqays be in and out of one.

so live life, get that job you always wanted, buy those new shoes and love yourself. depend on yourself, not others. they arent worth it, you can make yourself more happier than most people can do to you. it's not woth it. take your time and have fun.
