Marysya12 [62]

Answer:

Interphase

Explanation:

The phase in which most of the cells appear to be in is interphase.

This is so because cell's life is spent more in interphase and in this phase growth of cells and at the end their replication takes place. So cells get more time in interphase to grow and replicate, which makes more cells to appear to be in.

Hence, the correct answer is "Interphase".

Why is the nitrogen fixation carried out by cyanobacteria , bacteria and some archaea in marine environments important?
strojnjashka [21]
The nitrogen fixation is a very important process because it is the principal source of nitrogen in the marine environment for photosynthetic plants. Nitrogen is a growth limiting nutrient, that is very important for the growth of photosynthetic plants. During the process of nitrogen fixation, nitrogen is absorbed from the atmosphere and it is fixed by nitrogen fixing organisms.

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.
