[CM.04] List three reasons that fair weather predictions made by meteorologists are sometimes incorrect. Explain your response.
vlabodo [156]

1) Relying on computers and not going to the field. Sometimes a technical or software fault could lead to a wrong prediction. it could be a new forecaster who does not know the weather patterns and so follows the computer model instead of stepping outside and actually feeling the weather

2) The atmosphere always changes with natural disasters occurring such as pollutants in the air that make forecasting difficult.

3) Most of the times meteorologists base their forecasts on probability. Because of differences in the climate, those temperatures are not the same, so errors occur.

Hope this helps

vivado [14]

Answer:

<h2> Each daughter molecule contains one parent strand and one newly synthesized strand</h2>

Explanation:

In DNA replication, each daughter molecule contains one parent strand and one newly synthesized strand because DNA replication is semi-conservative. One template strand is parental strand and the other one is its complementary which is new one, which is synthesized by DNA polymerase enzyme. So both  daughter molecule contains one parent strand and one newly synthesized strand and they are same in the sequence of bases because each strand contains one original parental strand.
