It depends on what. Cylinder, cube etc?
Answer: carbon dioxide that enters through the leaf openings
Explanation:
Answer: The tuatara is a lizard-like reptile found only in New Zealand today, the last surviving lineage of a large group of reptiles that were contemporaries of the dinosaurs.
The traits that would i expect the <u>tuatara</u> to possess are:
- Spiny back similar to that of dinosaurs.
- A well developed pineal eye.
- It lacks a copulatory organ.
- Spine-like vertebrae with intercenters.
- Anterior teeth, large and very sharp.
Explanation:
<u>Living fossil</u> is an expression used to qualify non-extinct species that are extremely similar to species identified only through fossils.
A <em>pineal eye</em> is a part of the epithalamus present in some animal species. The eye can be a photoreceptor and is commonly associated with the pineal gland, regulating the circadian rhythm and hormonal production for thermoregulation. The tuatara has a developed parietal eye, <u>with retina and lens.</u>
The duplication of homeotic ( H o x ) genes has been significant in the evolution of animals because it <u>permitted </u><u>the </u><u>evolution </u><u>of novel forms</u>
<h3>What is the Hox genes and evolution?</h3>
Hox proteins are a family of transcription factors that have undergone extensive conservation. They were first identified in Drosophila for their crucial functions in regulating segmental identity along the antero-posterior (AP) axis.
The regionalization of the AP axis and changes in the expression patterns of these genes have been strongly correlated during the past 30 years across a wide range of evolutionarily distinct species, indicating that Hox genes have been essential in the evolution of new body plans within Bilateria.
Despite this extensive functional conservation and the significance of these genes for AP patterning, many important concerns about Hox biology remain.
