One half of each tetrad will have a maternal homolog:(1/2)^10 (one half to the tenth)
Yes, heart cells contain a complete set of chromosomes and DNA. However, during maturation, specific genes are expressed and others are silenced, leading to the development of specialized heart cell functions.
Human cells have 46 chromosomes (call that 2n, or 2 times n). Now then, if an egg cell + sperm cell = fertilized egg (which becomes a human), how many chromosomes do each have? An egg cell must have 23 chromosomes, and a sperm cell must have 23 chromosomes, because 23 + 23 = 46. When the egg (23) and sperm (23) combine to form a fertilized egg, this egg will now have 46 chromosomes. So human sex cells have n, or 23 chromosomes. If you mean to distinguish somatic chromosomes from sex chromosomes, then you have 22 pairs of somatic chromosomes plus one pair of sex chromosomes, for a total of 46 chromosomes.
Because mitosis is used for all cells except for brain, heart, muscle (because they do not duplicate) and sex cells (because they undergo meiosis). If the chromosomes are mixed, that means the horse and donkey went through sexual intercourse, therefore meiosis is taking place.
The main specialized cells that make up the heart are cardiomyocytes responsible for contraction, pacemaker cells that generate electrical impulses, and conductive cells that help spread the electrical signals throughout the heart.
No, the cells in the skin of your hand are different in size and function compared to the cells in your heart. Skin cells (keratinocytes) are relatively small and serve a protective function, while heart cells (cardiomyocytes) are larger and are specialized for contracting to pump blood.
That is false. All body cells, including heart muscle cells have 46 chromosomes. Sex cells have 23 chromosomes.
Yes, heart cells contain a complete set of chromosomes and DNA. However, during maturation, specific genes are expressed and others are silenced, leading to the development of specialized heart cell functions.
A giraffe's somatic cells, such as heart cells, will also have 31 chromosomes. This is because all cells in an organism's body carry the same set of chromosomes, with the exception of sex cells (gametes) which undergo meiosis to reduce their chromosome number by half.
Haploid is referred to a state in which only one set of chromosome is present from each Homologous pair. Suppose there is an organism that has three chromosomes: AA BB and XY. when the gametes are formed then the chromosomes will segregate and the cells formed are: ABX and ABY. These are both haploid sets.
15. A sperm cell is an example of a haploid cell. Two haploid cells combine to form a diploid cell, of which a heart cell is an example.
Human cells have 46 chromosomes (call that 2n, or 2 times n). Now then, if an egg cell + sperm cell = fertilized egg (which becomes a human), how many chromosomes do each have? An egg cell must have 23 chromosomes, and a sperm cell must have 23 chromosomes, because 23 + 23 = 46. When the egg (23) and sperm (23) combine to form a fertilized egg, this egg will now have 46 chromosomes. So human sex cells have n, or 23 chromosomes. If you mean to distinguish somatic chromosomes from sex chromosomes, then you have 22 pairs of somatic chromosomes plus one pair of sex chromosomes, for a total of 46 chromosomes.
Mitoses does take place in sexually reproducing organisms. There are two types of cells in your body, somatic cells (heart, skin, bones, etc.) and sex cells (eggs and sperm). Somatic cells all use mitosis to make more of themselves. Sex cells use meiosis to make more of themselves. If sex cells used mitosis instead of meiosis they would have too many chromosomes and the baby would have problems (if it survived at all).
A cell is the smallest part of a living organism that contains the identity within a strand of DNA. The cells of your body can grow into specialized functions such as heart or skin. Some microscopic organisms are 1 cell creatures or simple multi-cell organisms. That is what is mean by "All living organism are composed of cells."
Because mitosis is used for all cells except for brain, heart, muscle (because they do not duplicate) and sex cells (because they undergo meiosis). If the chromosomes are mixed, that means the horse and donkey went through sexual intercourse, therefore meiosis is taking place.
easiest question,ask your self why are viruses not living organisms? because they dont have cells!
It might attack because they have CHROMOSOMES it makes it easier for them to attack the heart.
No. Most microscopic organisms are much too tiny to have a heart.
