Answer:
B
Explanation:
Both of the original DNA strands act as templates during replication. This option is correct.
<h2>
<u>EARTH'S MAGNETIC FIELD</u></h2>
The magnets point North when the Earth's magnetic field has?
<h2>
<u>ANSWER</u></h2>
I think the best answer for this question is Magnetic Reversal or Geomagnetic Reversal.
In geomagnetism, the term "geomagnetic reversal" also known as 'flip', is the process by which the North pole becomes South pole and the South pole transforms into North pole.
<h2>
<u>THE MAGNETIC REVERSAL</u></h2>
The reversals happen on rare occasions when iron molecules start moving towards the opposite direction as other iron molecules around them within the Earth's spinning outer core.
Violet and blue have the high frequencies (thus energy) of visible light. Red will be the least energy but lowest energy. And remember, chlorophyll is green because it reflects green into our eyes. Green is therefore not absorbed, so not used for photosynthesis.
Answer:
genes for flower color and edge shape are linked. They do not assort independently.
Explanation:
<u>Available data:</u>
- test cross between a purple-flowered pea plant having serrated leaves and a white-flowered pea plant having smooth edges.
- serrated leaves → dominant trait
- smooth edges → recessive trait
- purple color → dominant trait
- white color → recessive trait
- F1: 4 purple-serrated:1 purple-smooth:1 white-serrated:4 white-smooth.
There are two genes involved in the cross. The expected ratios are 1:1:1:1 because we assume genes assort independently. However, we see a different phenotypic distribution. When phenotypic ratios differ from the expected ones, it means that genes are linked.
To know if two genes are linked in the same chromosome, we must observe the progeny distribution. If individuals, whose genes assort independently, are test crossed, they produce a progeny with equal phenotypic frequencies 1:1:1:1. But if instead of this distribution, we observe a different one, that is that phenotypes appear in different proportions, we can assume that genes are linked in the double heterozygote parent
