Answer:
The problems that can be caused by Expansion or Contraction a;long with the solutions are:
Explanation:
- The railway tracks made of steel expand during the summer and contract during the winter. This can cause them to become curved during the summer thereby causing rail derailment.In order to prevent this, an air gap is kept in between the railway lines so that they get the space to expand without getting curved.
- The electric wires linking the telegraph posts are made up of metals and so they expand in the summer and contract in the winter, which can cause them to tear. This is why the wires are loosely fixed so that they can expand and sag in the summer and contract and tighten in the winter.
- Bridges are constructed with joints where some space is maintained to allow the easy expansion and contraction in summer and winter respectively.

Here are the processes of bacterial transformation:
Explanation:
Bacterial transformation is defined as the change in the properties of bacteria which is caused by the introduction of foreign and naked DNA.
DNA is an hereditary material in organisms that contains their genetic information.
Here are the processes of bacterial transformation:
Step 1: Donor cell forms a Donor cell lyses
Step 2: Donor cell homologous binds to a receptor site on the recipient cell.
Step 3: One strand of donor cell DNA is degraded, and transformed DNA Pairs with homologous region on recipient cell.
Step 4: Finally, recombines with recipient cell chromosome
