Answer:
a. 6.5 × 10⁴ mmHg
b. 5.9 × 10⁻⁴ atm
c. 1.0 × 10⁵ Pa
d. 0.97 atm
Explanation:
Transformaremos las siguientes unidades utilizando factores de conversión.
a. 85 atm a mmHg
Usaremos el factor de conversion 1 atm = 760 mmHg.
85 atm × 760 mmHg/1 atm = 6.5 × 10⁴ mmHg
b. 60 Pa a atm
Usaremos el factor de conversion 1 atm = 101325 Pa.
60 Pa × 1 atm/101325 Pa = 5.9 × 10⁻⁴ atm
c. 780 mmHg a Pa
Usaremos el factor de conversion 760 mmHg = 101325 Pa.
780 mmHg × 101325 Pa/760 mmHg = 1.0 × 10⁵ Pa
d. 740 mmHg a atm
Usaremos el factor de conversion 1 atm = 760 mmHg.
740 mmHg × 1 atm/760 mmHg = 0.97 atm
Is it science ? cause the word blocks you just need to see which matches up with each word and make its way down
Answer:
hi is
Explanation:
Ans. (1) For preparing vaccines, in olden days,microbes were injected in the bodies of horses ormonkeys. These laboratory animals used to makeantibodies to defend these microbes. Antibodies areproteins which can act against the disease-causinggerms. These antibodies were extracted from theblood of these animals and were used as vaccines.(2) Now-a-days with the advent of biotechnology,the vaccines are manufactured in laboratories withthe help of bacteria. For this purpose, a detailedstudy of the disease causing germ is undertaken.The genes and the DNA of such microbes arethoroughly explored. Then based on thisinformation, proteins which can act against suchmicrobes are synthetically prepared in thelaboratories. The safe vaccine is produced in such away which can defend the body against infections.3) Some types of vaccines are prepared from theextracts of germs. These germs or microbes aredeactivated and made dormant. When they areinjected in the body of a person, they initiate thedefending action. The body of such vaccinatedperson, already develops the antibodies in his or herbody. When in future, this person is again attackedby similar germs the defence starts immediately andthe person does not become sick.
Answer: Geologists study rocks to find clues to Earth's formation. Evidence from rocks and fossils allows us to understand the evolution of life on Earth.
