Answer:
<em>Hox </em>Gene
Explanation:
First, you're question is very vital, there are many ways in classifying along with identifying all living organisms that includes; morphological analysis, molecular systematics (studying the similarities and differences of the genetic data such in the sequences of DNA, RNA, and rRNA ), homology, cladistics, etc. based on phylogenetic tree, which the study of the evolutionary among various species.
But through it said that all living organisms shared one common ancestor. However, what makes them different from one to another is the homeotic genes that called <em>Hox </em>Genes; which specify the fate of a particular segment or region of the body, meaning the number and arrangements of the<em> Hox</em> genes varies considerably among different types of animals.
For instance, Sponges have at least one homologous to<em> Hox</em> genes, also insects have nine or more <em>Hox </em>genes resulting in multiple <em>Hox </em>genes occur in a cluster in which the genes are close to each other along a chromosome. Therefore, increases in the number of<em> Hox</em> genes have been instrumental in the evolution of many animals species with greater complexity in body structure.
Overall, more <em>Hox</em> genes, more complexity in body structure resulting in the differences of their morphological structure.
Hope that answered your question!
Answer:
The faster the particles are moving, the more energy they have. Why is convection more important than conduction in the troposphere? The air doesn't conduct heat well so only the first few meters of the troposphere are heated with conduction
Answer: They do this to obtain the vital nitrogen that they need to grow.
Explanation:
I do not think the industrial and agricultural revolutions could have occurred without the environmental costs. The industrial revolution in the 18th century occurred at a time in history when people where not aware of the consequences of their actions or the consequences of the widespread use of fossil fuels. Even if they were aware the technology would not have been present to harness power from natural renewable sources of energy.
