No offense, but you’re asking somebody to write basically an entire essay. Try to think of what YOU would do. Every journal is written differently.
<span>
1. The genetic material is a good evidence of evolution because it's been conserved through time but with some slight differences.
Another important aspect is the </span><span>mitochondria.</span><span> The mitochondria resulted from a symbiotic relationship
between bacteria and pre-eukaryotes. Explaining why the </span><span>mitochondria looks like a bacteria and has </span><span>bacterial DNA.
2. specialized cellular modifications:
There are cellular modifications happening in multicellular organisms. That means, they have different types of cells, with different functions and will express different characteristics. For example:
- </span><span>Nerve
cells have
dendrites which is important to receive the electrical signal from another neuron, other cells don't have that.
- Sperm cells have a tail ( </span><span><span><span>flagellum) in order to swim through the vagina and no other cell has that.

Answer:
On the basis of physical traits.
Explanation:
Newer classification systems classify organisms on the basis of physical traits of an organism. All modern classification systems gets their concept and help from Linnaean classification system. In these new classification systems, those organisms that have similar characteristics are placed in one group because they evolve from the same ancestor or having common ancestry. These changes occurs in the organisms with the passage of time that helps organisms to survive in that environment.
Stem cells of the animals are the most similar to the meristematic cells of the plant.
<u>Explanation:</u>
- Meristematic cells are the most important cells for the plant which give rise to the various tissues and plant organs. These meristematic cells are capable to undergo cell division and they are called totipotent.
- The stem cells of animals and humans are capable of doing the function by replacing the new cells for growth and development.
- The difference among these two tissues is that meristematic is capable to produce total organs whereas stem cells are capable to produce only specific tissues.
The person correlation coefficient,r, can take a range of value from+1 -1. a value of 0indicates that there is no association between the two variable.
