Do fish have nuclei in their red blood cells?
No, fish typically do not have nuclei in their red blood cells. Most mature fish red blood cells are enucleated, meaning they do not contain a nucleus. This allows for more efficient oxygen transport in their bloodstream.
Which cells contain more DNA than the other?
Most of the DNA inside a human cell is contained in the nucleus, but a small amount is found in the mitochondria. The nucleus is an organelle found inside most cells, but not red blood cells. The nucleus is not a cell, just like a dinning room is not a house.All the cells in a human body with the exception of the sex cells and red blood cells contain the same amount of DNA in the nucleus. Some cells contain more mitochondria which have a little extra DNA so probably muscle or liver cells would contain the most as they need the most energy and so have the most mitochondria.To work out which cell in the world contains the most DNA we could try looking at which species has the largest genome. So far the biggest animal genome sequenced is that of Protopterus aethiopicus, the Marbled lungfish at 132.83pg of DNA per cell. So probably Marble lung fish muscle or liver cells will contain the most DNA in an animal species. We do not know the size of every species genome yet so this is really a guess.Well for Study Island, the answer is, in fact, Nucleus
What type of blood do fish have?
Most fish have blood that is very similar to human blood, consisting of red blood cells, white blood cells, and platelets. However, fish blood also contains nucleated red blood cells, which is a key difference from mammalian blood.
Are salmon eukaryote or prokaryote?
Salmon are eukaryotes. Eukaryotes are organisms whose cells contain a nucleus and other membrane-bound organelles, which is characteristic of all animals, including fish like salmon. In contrast, prokaryotes are simpler organisms, such as bacteria, that lack a nucleus.
What does the fish's spleen do?
A fish's spleen does what a human's spleen does, releases blood cells when needed
Why are red blood cells non-nucleated?
when mammals began to evolve. Other vertebrates such as fish, reptiles and birds have red cells that contain nuclei that are inactive. Losing the nucleus enables the red blood cell to contain more oxygen-carrying hemoglobin, thus enabling more oxygen to be transported in the blood and boosting our metabolism.
Are jellyfish prokaryotic?
No, jellyfish are not prokaryotic. Jellyfish are eukaryotic organisms, meaning they have complex cells with a true nucleus and other organelles. Prokaryotic cells, on the other hand, are simpler cells that lack a true nucleus and organelles.
Does a fish have a nucleus?
Fish are type of animals.They do have a nucleus.
Do fish have eukaryotic cells?
Organisms with eukaryotic cells are called eukaryotes. All animals, plants and fungi are eukaryotes. Since a sardine is an animal (a species of fish), it is a eukaryote and has eukaryotic cells.
Are fish prokaryotic or eukaryotic?
Fish are eukaryotic, meaning they have cells with a defined nucleus containing their genetic material, just like humans and other animals. This nucleus is enclosed within a membrane and fish also have other membrane-bound organelles within their cells.
What is an example of a cell in the circulatory system?
someone please answer this question i need it for homework like now!
Are there two kinds of cells animals and fish known to exist?
Yes, animals and fish are composed of cells, which are the basic structural and functional units of living organisms. Cells in animals and fish are eukaryotic, meaning they have a defined nucleus that houses their genetic material. Both animals and fish have specialized cells that perform specific functions to maintain their overall biological processes.
