What are the similarities between prokaryotes, eukaryotes and viruses?

Answers

Like a prokaryotic cell, a eukaryotic cell has a plasma membrane, cytoplasm, and ribosomes, but a eukaryotic cell is typically larger than a prokaryotic cell, has a true nucleus and has other membrane-bound organelles that allow for compartmentalization of functions.

Final answer:

Prokaryotes, eukaryotes, and viruses share similarities in containing genetic material and reproduction capacity. However, differences occur in genetic material structure, cellular structures, and functioning mechanisms.

Explanation:

The similarities between prokaryotes, eukaryotes and viruses essentially revolve around their basic biological functions. All three entities contain some form of genetic material (either DNA or RNA) which governs their basic life processes. They also have the capability to reproduce, although viruses require a host cell to accomplish this task. However, the structures of their genetic materials vary significantly. Prokaryotes and eukaryotes possess cellular structures necessary for functioning, but viruses largely lack these and are rather considered as non-living biological entities. Hence, they are comparable in their fundamental existence but differ vastly in their forms and functional mechanisms.

The downfall of a tragic character is the result of __________.chance
a tragic flaw
the antagonist
poverty

Answers

The downfall of a tragic character is the result of "a tragic flaw".


The term hero is gotten from a Greek word that implies a man who faces affliction, or shows strength, despite risk. Nonetheless, at times he faces ruin too. At the point when a hero goes up against destruction, he is perceived as a tragic hero. Aristotle, the Greek philosopher, portrays these plays or stories, in which the principle character is a shocking saint, as disasters. Here, the hero goes up against his ruin whether because of destiny, or by his own oversight, or some other social reason.

How do enzymes speed up chemical reactions

Answers

They lower the activation energy, that is required for a specific process.

The enzyme works like a lock and key, where the lock is the enzyme that gets activated by a molecule the "key". Once they bind to each other the process gets started.

Without enzymes the process would have to occur entirely on it's own.

Answer

By lowering energy of activation of the reaction.


Explanation

High energy produced during the metabolism of reactant to product. Due to the large free energy of activation, the speeds of uncatalyzed biochemical reactions are often exceedingly slow. Enzymes lower this energy of activation so that more molecules have adequate energy to carry into the transition state to speed up the rate of reaction.

Farmers looking to grow large quantities of food quickly would utilize plants that reproduce _____.

Answers

The answer is asexually.

The reason why plants that reproduce asexually than plants that reproduce sexually is because in asexual reproduction only one parent is needed, so there is no need for pollination and it is time and energy efficient. That means that farmers can grow large quantities for less time.
