Write down three problems caused by expansion or contraction.how are these problems overcome?
masya89 [10]

Answer:

The problems that can be caused by Expansion or Contraction a;long with the solutions are:

Explanation:

  1. 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.
  2. 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.
  3. Bridges are constructed with joints where some space is maintained to allow the easy expansion and contraction in summer and winter respectively.

Genes are segments of DNA located on chromosomes. A gene mutation is defined as an alteration in the sequence of nucleotides in DNA. This change can affect a single nucleotide pair or larger gene segments of a chromosome. DNA consists of a polymer of nucleotides joined together. During protein synthesis, DNA is transcribed into RNA and then translated to produce proteins. Altering nucleotide sequences most often results in nonfunctioning proteins. Mutations cause changes in the genetic code that lead to genetic variation and the potential to develop the disease. Gene mutations can be generally categorized into two types: point mutations and base-pair insertions or deletions.

What is one change that would cause more water to evaporate from a stream?
Svetllana [295]

Evaporation

Explanation:

Evaporation is one change that would cause more water to evaporate from a stream.

Evaporation is a phase change in which liquid is changed into its gaseous form.

  • When a substance is heated from solid to liquid, it melts.
  • After melting, additional heat causes a phase change that allows for the liquid to change to gases.
  • In the water cycle, the sun provides heat energy that causes surface water in streams to be heated.
  • This leads to evaporation of the surface water into the atmosphere where they can be condensed to form precipitation.
