The answer is that the criteria of classification change whith the improved understanding of organisms around us
Physical differences in beaks of birds would develop as a result of different environmental changes.
<h3>What is Evolution?</h3>
This is described as the process in which heritable characteristics are changed in species over successive generations. This occurs as a result of natural selection in which the traits suitable for survival are passed to the offspring.
This is usually as a result of a change in the environmental factors which ensures that the organisms are able to adapt so as not to die out and go extinct in this type of scenario.

Answer:
It is better to compare the average height gain of control and experimental groups of plants to eliminate all other variables.
Explanation:
If you evaluate individual plants, the data may vary. The experimental group is the one where an experimental procedure is performed while the control group does not receive any treatment.
Answer:
There are three types of DNA Mutations: base substitutions, deletions and insertions.
Base Substitutions. Single base substitutions are called point mutations, recall the point mutation Glu -----> Val which causes sickle-cell disease.
Deletions. ...
Insertions.
The abiotic factors that could cause the sea cucumbers to
differ their distance from one another are temperature, time of the day, and
humidity. The biotic factors that could influence are the organisms around
these creatures. Furthermore, the independent variable in this study is the
time of the day where observed are the average distance between these sea
creatures and their output, the distribution of sea cucumbers as the dependent
variable.
Hypothesis: There is a link between the time of the day and the distance of sea cucumbers amongst each other.
