Why is the nucleus called the 'control centre' of the cell?
The nucleus is like the brain of the cell.The other reason why nucleus is called the control center is that- It has genetic material called DNA which undergo different functions such as replication, transcription, translation i.e. formation of different enzymes and proteins necessary for the development of whole cell Another reason is that-the cell which lac nucleus during abnormal cell division known to be dead cell. Also, the nucleus controls the food that is transported in and out of the cell.
In congestive heart failure the weakened heart is unable to pump with sufficient strength to empty its own chambers. As a result blood backs up in the veins blood pressure rises and circulation is imp?
O.K. except that the blood pressure falls. Fluid is retained (by the kidneys) to increase total body fluid - and thus veinus pressure, which injects extra fluid into the heart, thus compensating for the failure to empty the chambers normally.
Which kingdom is part of domain Eukarya?
Domain Eukarya, or eukaryotic organisms, are pretty much organisms with a nucleus(eukaryote comes from greek meaning "true kernel/nut", referring to the presence of the nucleus). This is opposed to the prokaryotic organisms and archaea, which do not have a nucleus.
What characteristics of red blood cells help them perform their function?
Red blood cells (RBC) are roundly shaped and have an indent in the middle (like a donut) but no hole. The indent is to increase the surface area of the RBC, thus, making the RBC highly efficient. The function of a RBC is to carry oxygen and other needed nutrients to specific areas of the human body, also is certain parts of the body, carry waste from an area to the liver.
What are the three basic particles of an atom?
First Answer: The three basic particles of an atom are protons, neutrons and electrons. The proton and neutron comprises of the nucleus of an atom but electrons revolve around the nucleus continuously. The protons are positively charged and electrons are negatively charged while the neutrons are neutral. Thus we can say the whole atom is neutral. Second Answer: 1) Proton (Positive) 2) Neutron (Neutral) 3) Electron (Negative)
What is the only cell in the human body that doesn't have a nucleus?
Mature red blood cells are the only human cells that do not have a nucleus. sorry to do this but that's not the answer but i don't know it
What would happen if you tried to make a karyotype from isolated mature red blood cells?
You must be in genetics lab... Red blood cells do not have a nucleus therefore a karyotype cannot be assembled. The chromosomal preparations cannot be performed on the red blood cells. Thus, the reason they use white blood cells.
Mature red blood cells have two nuclei?
red blood cells gradually become filled with hemoglobin, their nuclei and other organelles are forced out. Thus, mature red blood cells do not have nuclei.
Does the mature red blood cell have two nuclei?
As red blood cells gradually become filled with hemoglobin, their nuclei and other organelles are forced out. Thus, mature red blood cells do not have nuclei.
Does peptidoglycan lack a membrane enclosed nucleus?
Well...technically yes. It should be taken into consideration that peptidoglycan is a polymer that a bacterial cell wall is composed of. Therefore, it is not alive and technically lacks a membrane. On the other hand, the cell on which the peptidoglycan is present lacks a membrane enclosed nucleus, thus making it prokaryotic.
What structure is missing from the red blood cell that is found in most other cells?
Red blood cells that lose their nucleus also lose their mitochondria. It is an adaptation of the red blood cells in order to carry more oxygen and transport the oxygen to the different parts of the body.
What organisms have cells without nuclei?
Cells that do not contain a "true" nucleus are called prokaryotes. Sometimes eukaryotic cells are anucleate(no nucleus) when mature. Erythrocytes (red blood cells) in mammals are an example of eukaryotic cells that do not contain a nucleus when mature.
Single-celled organisms that do not have a membrane-bound nucleus?
Bacteria lacks a nucleus but have a fully developed DNA, thus they can be considered full cells. Virus also lack a nucleus, but they have not a fully developed DNA. Even virus having RNA only exist. For this reason virus are somehow in between cells and simple multiple molecular systems.
Are red blood cells unicellular?
Yes, red blood cells aren't stuck together. Did you mean are they mono-nucleate- as in have only one nucleus? If so, that's a no- red blood cells don't have a nucleus, thus they're described as enucleate.
Do red blood cells have a cell membrane?
Yes, red blood cells (erythrocytes) have a cell membrane, but they don't contain a nucleus- thus they're described as enucleate.
How are cells able to live side by side?
In the Nucleus there is a process called photosynthesis and when this happends white blood cells explaned thus making starch
Why is Just Cause rated M?
Just cause is rated M for violence drugs animated blood and I think alcohol abuse thus standing for Mature or the people that chose Mature chose it for more reasons that they saw I hope this answered your question
