What do eukaryotic cells have that prokaryotes lack?
The primary distinction between these two types of organisms is that eukaryotic cells have a membrane-bound nucleus and prokaryotic cells do not. The nucleus is only one of many membrane-bound organelles in eukaryotes. Prokaryotes, on the other hand, have no membrane-bound organelles.
What are the 4 types of eukaryotic cells?
There are four types of eukaryotes: animals, plants, fungi, and protists. Protists are a group of organisms defined as being eukaryotic but not animals, plants, or fungi; this group includes protozoa, slime molds, and some algae.
Which domain has bacteria that can live in extreme conditions?
Is human blood prokaryotic or eukaryotic?
Eukaryotic cells are found in plants, animals, fungi, and protists. They generally have a nucleus—an organelle surrounded by a membrane called the nuclear envelope—where DNA is stored. There are a few exceptions to this generalization, such as human red blood cells, which don’t have a nucleus when mature.
Is human eukaryote or prokaryote?
Despite the fact that we have gobs of prokaryotic cells living inside and on us, humans are still categorically eukaryotic organisms. This means that all human cells—including those found in the brain, the heart, the muscles, and so on—are also eukaryotic.
Why do humans belong to the domain eukarya?

Are our pinky fingers getting smaller?
Our DNA can’t tell whether or not we are using our pinky. So our kids’ pinkies won’t be shorter just because we didn’t use ours. In other words, not using a pinky will not alter our DNA to make the next generation’s pinkies smaller. This isn’t how genetics works.
Why do yakuza cut their finger off?

Why is the pinky finger so weak?
The Index or Pointer finger has something special as does the little finger. Each of these fingers have one additional muscle and tendon. The fact that you are preventing the muscle from acting on all the fingers kind of negates it’s power, making the ring finger weaker.
