A concept that ypu try to proveYour welcome is the correct spelling
Answer:
Plant cells and animal cells are both eukaryotic hence, they have many similar organelles. Common organelles are:
Cell membrane: the structure that separates a cell from exterior environment.
Nucleus: structure where hereditary material is present.
Ribosome: structure where proteins are made.
Endoplasmic Reticulum: associate in protein production
Golgi complex: structure where proteins are modified and packaged.
Vacuole: acts as a storage house for a cell
Cytoplasm: fluid in which all the organelles float.
The majority of mutations have neither negative nor positive effects on the organism in which they occur.
D) The AV valves are supported by chordae tendineae so that they do not blow back up into the atria during ventricular contraction.
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!
