Answer: 1. b. Agrobacterium The ability of Agrobacterium to transfer genes to plants and fungi is used in biotechnology, in particular, genetic engineering for plant improvement. A modified Ti or Ri plasmid can be used. 2. c. Artificial active Artificially acquired active immunity can be induced by a vaccine, a substance that contains the antigen. 3. c. Attenuated An attenuated vaccine is a vaccine created by reducing the virulence of a pathogen, but still keeping it viable (or \"live\"). Attenuation takes an infectious agent and alters it so that it becomes harmless or less virulent. 4. a. Sign Symptom is nothing but the abnormal phenotype expressed in living organisms. Symdrome means the all abnormalities associated with the disease. 5. b. The eye Normal flora can be found in many sites of the human bodyincluding the skin (especially the moist areas, such as the groin and between the toes), respiratory tract (particularly the nose), urinary tract, and the digestive tract (primarily the mouth and the colon).

1. Answer:
1. b. Agrobacterium
The ability of Agrobacterium to transfer genes to plants and fungi is used in biotechnology, in
particular, genetic engineering for plant improvement. A modified Ti or Ri plasmid can be used.
2. c. Artificial active
Artificially acquired active immunity can be induced by a vaccine, a substance that contains the
antigen.
3. c. Attenuated
An attenuated vaccine is a vaccine created by reducing the virulence of a pathogen, but still
keeping it viable (or "live"). Attenuation takes an infectious agent and alters it so that it
becomes harmless or less virulent.
4. a. Sign
Symptom is nothing but the abnormal phenotype expressed in living organisms. Symdrome
means the all abnormalities associated with the disease.
5. b. The eye
Normal flora can be found in many sites of the human bodyincluding the skin (especially the
moist areas, such as the groin and between the toes), respiratory tract (particularly the nose),
urinary tract, and the digestive tract (primarily the mouth and the colon).

particular, genetic engineering for plant improvement. A modified Ti or Ri plasmid can be used.
2. c. Artificial active
Artificially acquired active immunity can be induced by a vaccine, a substance that contains the
antigen.
3. c. Attenuated
An attenuated vaccine is a vaccine created by reducing the virulence of a pathogen, but still
keeping it viable (or "live"). Attenuation takes an infectious agent and alters it so that it
becomes harmless or less virulent.
4. a. Sign
Symptom is nothing but the abnormal phenotype expressed in living organisms. Symdrome
means the all abnormalities associated with the disease.

2. 5. b. The eye
Normal flora can be found in many sites of the human bodyincluding the skin (especially the
moist areas, such as the groin and between the toes), respiratory tract (particularly the nose),
urinary tract, and the digestive tract (primarily the mouth and the colon).
