Answer:

MUTATION

Explanation:

As said in the question, changes in nucleotide bases that make up the genetic material (DNA) occur from time to time. This change called MUTATION can either occur as a result of copying mistakes during replication or be induced by mutagens (mutation-causing components). If the affected cell is not internally corrected using mismatch pair mechanism and it keeps dividing, it could possibly serious problems to the affected organism.

The kind of change described in the question is a SUBSTITUTION MUTATION, in which a nuceleotide base replaces another in the DNA sequence i.e. C replaces T.

Answer:

The cornea is shaped like a dome and bends light to help the eye focus. Some of this light enters the eye through an opening called the pupil (PYOO-pul).

In one to two sentences, explain why low-pressure systems are associated with bad weather? (2 points)
Arisa [49]

Low pressure systems leads to the formation of clouds and precipitations.

<h3>Causes of bad weather</h3>

Atmospheric pressure is defined as the force per unit area that is exerted by the weight of the atmosphere. The weather can be affected by changes in the atmospheric pressure.

When there is low atmospheric pressure, there is formation of clouds and precipitations.

The formation of clouds such as cumulonimbus can indicate nearby threat of severe weather, including bursts of rainfall, hail, and possibly even tornadoes.

Low pressure can lead to precipitation which causes formation of fog and mist that distorts atmospheric visibility.

Therefore, low pressure systems leads to the formation of clouds and precipitations.
