B. isotopes
C. elements
D. molecules
Answer:
IONS
Explanation:
Scientists would deal with the aspect of cloning a particular gene into a bacterium or making of hybridoma cells that will produce the particular required protein. Engineers will then design and develop a bioreactor which is a programmed instrument that avails the required substances to the cells/bacteria in specific amounts and at particular time periods to grow and reproduce the cells in large amounts.
Answer:
No
Explanation:
Hello,
Since the sealed glass container is isolated (closed system) no escape of boiled water (steam) was presented, so it is obvious that the alchemists were wrong, it is impossible that the water turns into "earth" because it has components that water does not have by itself (metallic and nonmetallic ions and molecular compounds) that is why the solid residue could have come from suspended solids or simply solids that were initially dissolved and due to the boiling of water, they remained at the bottom of the flask. Nevertheless, the experiment done by Lavoisier was more precise because the conclusion based on the initial and final masses, accounts for the boiling process; besides, the mass agreement substantiates that no mass was removed due to the isolation of the flask.
Best regards.
B. nuclear separation.
C. nuclear fission.
D. nuclear fusion.
Answer is: C. nuclear fission.
Nuclear fission is a nuclear reaction or a radioactive decay where nucleus of atom split into smaller ligher nuclei.
Nuclear fission is exothermic reaction which release large amounts of energy (electromagnetic radiation or as kinetic energy, which heat reactors where fission reaction take place).
Answer: The process of splitting of an atom into two lighter atoms is called is called nuclear fission.
Explanation:
There are two types of nuclear decay reactions:
Hence, the process of splitting of an atom into two lighter atoms is called is called nuclear fission.
