That is not the correct answer
<span>The answer is : Both have true necks, while eusthenopteron has no neck. </span>We know that tiktaalik is more closely related to acanthostega than it is Ichthyostega eusthenopteron because Tiktaalik and Acanthostega both have true necks while eusthenopteron has none.
Kile should know the answer because of the morphology (part of biology that studies the estructure and the form of something). The plant cell presents a rectangular form, while the animal's cells presents a round form.
There are other main differences. As their parts and the size. Before I explain that remember that a cell can be of two types eukaryotic (cell with nucleus) and prokaryote (cell with no nucleus). In the other they can be neurons, nefrons, etc...
The plant cell contains for example chloroplasts, cell wall and vascuoles; while animal's don't. Both of them have nucleus, cell plants are generally larger than animals. Those are the main differences.
Thankyou.
Sorry for my bad english, It's not my native language.
<span>Crossover is the first way that genes are shuffled to give rise to genetic diversity. Crossover takes place in sexual reproduction. Chromosomes line up side by side and break off pieces of themselves, then trade those pieces with each other. When they break at the same place (locus) in the sequence of base pairs, the result is an exchange of genes called genetic recombination. That is the normal way for crossover to occur. Genetic recombination ensures that the daughter cells produced have a different genetic makeup from the parent cell and thus diversity is created.</span>
C. Hardness is the answer
