What is the normal number of chromosomes in human body cells?
Each organism has a distinct number of chromosomes, in humans, every cell contains 46 chromosomes. Other organisms have different numbers, for instance, a dog has 78 chromosomes per cell. Somatic Cells - body cells, such as muscle, skin, blood ...etc. These cells contain a complete set of chromosomes (46 in humans) and are called DIPLOID. Sex Cells - also known as gametes. These cells contain half the number of chromosomes as body cells and are called HAPLOID Chromosomes come in pairs, called Homologous Pairs (or homologs). Imagine homologs as a matching set, but they are not exacly alike, like a pair of shoes. Diploid cells have 23 homologous pairs = total of 46 Haploid cells have 23 chromosomes (that are not paired) = total of 23
During what phase of meiosis do chromosomes pull apart?
The sister-chromatids are separated during anaphase.They are pulled apart by microtubules of the cytoskeleton. Once apart, they are known as chromosomes (or daughter-chromosomes).
How do scientist discovers cells?
The easiest and most common way for scientists to view cells is to look at them under a light microscope. A thin segment of the sample tissue is usually taken, stained, and mounted on a microscope slide.Most plant and animal cells are too small (1-100 µm) to be viewed except under a microscope.
Imagine your in a dark room how do you get out?
Flor
Can a brain imagine something it has never seen?
Yes it is called dreaming
How chromosomes get ready for cell to split?
the chromosomes are replicated (copied) and are compacted into dense visible structures
How does a volox move?
the move by kind of spinning, like imagine a birds-eye view of a human with a bunch of arms spinning very slowly, and waving those arms as they go. if you cant imagine that, look in a microscope and find out yourself.
What is a thread like structures containing the genetic material?
A chromosome is the threadlike nuclear structure that contains genetic information .
What is the purpose of somatic cells?
Somatic cells are body cells that contain a full set of chromosomes. I imagine that a somatic cell donor donates healthy body cells to someone who needs them.
What are the disadvantages of the scanning tunneling microscope as compared to a conventional microscope?
The best way to illustrate the disadvantages of the scanning tunneling microscope (STM) over a conventional microscope might best be shown by a comparison. Imagine using a pair of field glasses to watch birds in a heavily wooded area. Now imagine watching those birds in the same area with an 8" reflecting telescope and a "big" eyepiece. You could be looking at a bird with the telescope and not know it because you wouldn't even be able to see the whole bird.The STM can map a single atom on the surface of a sample with its probe, but it cannot show us the shape of a single celled animal because it is extremely powerful -- too powerful for that application. The microscope is something we can use all day to study tiny animals like, say, an amoeba.

Is it possible to look at an atom with a microscope?
Yes and no. It is not possible to look at an individual atom with an optical microscope. The reason for this, surprisingly enough, is that photons are too big (in terms of wavelength) and atoms are too small. This might be surprising. Nevertheless, the wavelengths of photons to which the human eye is sensitive are 4000 to 7000 Angstroms, but the size of an atom is 1 to 7 Angstroms (roughly). There are special microscopes that use electrons, instead of photons, to gather information. A tunnelling electron microscope is such a device. But they are not what most people imagine when they hear the word "microscope."
What are all the imagine ds games?
there are Imagine: Babies/babyz, Imagine: Fashion designer, Imagine: dream wedding or wedding designer, Imagine: Interior designer, Imagine: teacher, Imagine: My secret world, Imagine: Fashion designer new york, Imagine: Animal doctor, Imagine: figure skater, Imagine: fashion model, Imagine: champion rider and Imagine: pet vet however apparently you can also get Imagine: Master chef, Imagine: Gymnast, Imagine: Rock Star and Imagine: Movie Star. There are probably more but hope it helps :D
What was the greatest invension ever made?
i would say it was the wheel Oh, tough one... for me it's between bleach and the microscope although the integrated circuit comes in the top ten, I should imagine that the brain of the person who has written the above answer.
Can you see an individual atom?
We can see atoms but only through very powerful scanning tunnel microscopes and we can only see their outer shell and not whats inside. With the aid of nanothechnology we can now even arrange atoms. But we are a long time of seeing atoms beyond their shell.
