Answer:
Speciation is an evolutionary process by which a new species comes into being. A species is a group of organisms that can reproduce with one another to produce fertile offspring and is reproductively isolated from other organisms. Speciation can be driven by evolution, which is a process that results in the accumulation of many small genetic changes called mutations in a population over a long period of time. There are a number of different mechanisms that may drive speciation. One of these is natural selection, which is a process that increases the frequency of advantageous gene variants, called alleles, in a population. Natural selection can result in organisms that are more likely to survive and reproduce and may eventually lead to speciation. A second process called genetic drift describes random fluctuations in allele frequencies in populations, which can eventually cause a population of organisms to be genetically distinct from its original population and result in the formation of a new species.
Explanation:
Pituitary gland: Responsible for growth and reproduction, it secretes and stores hormones and influences how other glands act.
Adrenal gland: It’s responsible for producing certain steroid hormones, including aldosterone and cortisol.
It's a vague description of the two.
Given what we know, we can confirm that using the using the Whitaker system, kingdoms are grouped based on cell structure and type, while the whoese-fox system groups major taxonomic groups into three major domains.
<h3>What is the Whitaker system?</h3>
- The Whitaker system is a classification system to order and organize the diverse biological life found on Earth.
- This is the most commonly-known system which orders organisms into the 5 kingdoms.
<h3>What is the Whoese-fox system?</h3>
- This is a much less popular system of classification for biological life.
- It is considered to be much less specific, containing only 3 groupings.

Therefore, we can confirm that based on the statement, the spaces missing correspond to the scientists for who the systems are named after, which are Whitaker and Whoese-fox.
