Answer:
DNA is essentially a storage molecule. It contains all of the instructions a cell needs to sustain itself. These instructions are found within genes, which are sections of DNA made up of specific sequences of nucleotides. In order to be implemented, the instructions contained within genes must be expressed, or copied into a form that can be used by cells to produce the proteins needed to support life.
Explanation:
In humans, each cell normally contains 23 pairs of chromosomes, for a total of 46. Twenty-two of these pairs, called autosomes, look the same in both males and females. The 23rd pair, the sex chromosomes, differ between males and females.
The specification 'leaves found in deciduous forest and leaves found in tropical forest' should not be used when making this dichotomous key. It is not part of a classification system.
<h3>What is a dichotomous key?</h3>
A dichotomous key is a methodology employed by taxonomists to identify organisms from different taxonomic groups.
The dichotomous keys are always funded on phenotypic traits.
Dichotomous keys can be considered as two different options to identify a given feature of an organism.
