B.
Science is abandoned as a way to generate knowledge.
C.
The new knowledge is used to reevaluate the theory.
D.
The new knowledge is ignored in favor of the old theory.
Answer:
B: The new knowledge is used to reevaluate the theory.
Explanation:
2.
3. Each cell makes a complementary DNA strand.
4. The cells separate.
Which is the missing step for the process of conjugation described?
Answer:
2. The Fusion of cell membranes and transfer of single strand of plasmid DNA of donor cell.
Explanation:
When one bacterium transfers its genetic material through direct contact to others. The bacterium transfers its genetic material called donor cell and one serves it called recipient cell.
There are mainly four steps in this process-
1. Connecting sex pilus to recipient cell by donor cell.
2. The Fusion of cell membranes and transfer of single strand of DNA to the recipient cell.
3. Each bacterium cell makes a complementary DNA strand.
4. Both bacterium cells separates.
Answer:
Genetic Mutation
Bugs evolved themselves to adapt to this chemical
Explanation:
Genetic mutation in bugs has caused such changes in them. There is a high probability that some enzymes must have developed with in the bugs which inhibits the fatal impacts of this chemicals. So , it can be said that the genetics of bugs adapted the chemical due to which it is producing no negative impacts on them. And since this is a genetic change it is being transferred to the next generation.
