The Lederberg experiment that used the technique of replica plating showed that mutations are random and are not a result of the needs of the organism.
<h3 /><h3>What is a random mutation?</h3>
Random mutations are just that, they are changes in the genome of an organism that arise randomly. These mutations are the backbone of evolution and natural selection in that when they arise, if the organism becomes more adapted to survival as a result of this mutation, it increases its odds of survival through natural selection.
Therefore, we can confirm that The Lederberg experiment that used the technique of replica plating showed that mutations are random and are not a result of the needs of the organism.

This is true.
Birds evolved and adapted these features over time.
Answer:
A flower can either be classified as a monocot or a dicot depending on the number of petals present on the flower.
Explanation:
- Monocot also known as monocotyledon are characterized by the presence of one sees leaf(cotyledon) inside the embryo
The seed leaf is often thin because the endosperm which is required to feed the young plant is not found inside the seed leaf. In monocot flower a the number of petals is 3 or a multiple of 3. Examples of monocot flowers include; Asparagales, Wedges, Bromeliads, Poles.
- Dicots also known as dicotyledons are flowering plants that have two seed leaf. In a dicot flower the number of petals is 4 or 5 or a multiple of 4 or 5. Examples of dicot flowers include; Roses, Magnolas, Sunflower, Geranium.
