What is a described cell that has pairs of chromosomes?
This cell is called a diploid cell.
What are cells with two of each kind of chromosomes described as?
Diploid cells .
What are stem cells described as?
stem cells are described as cells part of the embryo where fertilized human egg cells have 23 pairs of chromosomes
How many chromosomes does a spotted salamander have?
almost all salamanders have 24 chromosomes. I don't believe it is any different for the "spotted"- most likely wild type- creature you have described.
In an ovum the number of chromosomes could best be described as?
large molecule that have only one function
If the liver cell of an animal have 24 chromosomes how many chromosomes do its sperm cells have?
Body cells, like liver cells, are diploid. This means they have pairs of chromosomes. In this example the diploid number of chromosomes is 24. In sperm cells (or egg cells) the number of chromosomes is halved. This is described as the haploidnumber. In this example the haploid number would be 24/2 = 12. So the number of chromosomes in the sperm cells would be 12.
Can be described as alternate forms of a particular gene Chromatids Alleles Chromosomes DNA molecules?
Alleles are alternate forms of particular genes.
Why is meiosis described as a precess of reduction division?
Because the chromosomes are reduced from 2n to n. From diploid( sister chromatids ) to haploid ( one chromosome ).
What is the rod-like structures in the nucleus that contain DNA?
chromosomes, are you doing the function of the organelles worksheet? ha ha I'm doing the function of the organelles worksheet and my stupid teacher didn't teach us what the hairlike structures with the capacity for movement is and i'm not talking about the cilia. the flagella is the hairlike structure with the capacity for movements.
What discovery in the 1900 supported Mendel's ideas?
Chromosomes
What is the karyotype for a normal human female?
A normal female karyotype would be described as 46 XX. A karotype shows the pairs of metaphase chromosomes of an individual cell and sorted according to size.
Who discovered meiosis?
Meiosis was discovered and described for the first time in sea urchin eggs in 1876 by the German biologist Oscar Hertwig. It was described again in 1883, at the level of chromosomes, by the Belgian zoologist Edouard Van Beneden, in Ascarisworms' eggs.
