Are stomatic cells haploid or diploid?
Somatic cells (of the body) are diploid (having 46 chromosomes). Only gametes (eggs and sperm) are haploid (having 23 chromosomes). So that during fertilization the egg and sperm combine their chromosomes resulting in a new life with 46 unique chromosomes (in humans, of course. Others species has differing numbers of chromosomes). The haploid combination ensures genetic diversity.
Describe some of the pieces of information that scientists discovered that contributed to the chromosome theory of inheritance?
Scientists discovered that chromosomes are inherited in a predictable manner during cell division, they observed that the number of chromosomes in a species is constant, and that specific traits are linked to particular chromosomes. They also found evidence of chromosomes segregating independently during meiosis.
What about human haploid cells is true?
Human haploid cells contain half the number of chromosomes (23) compared to diploid cells (46). Haploid cells are involved in the formation of gametes (sperm and egg) during meiosis. In humans, haploid cells are only present in the gametes and not in somatic cells.
What might happen to a new cell if it didn't have the same amount of chromosomes as the original cell?
Then it's a prokaryote cell (such as bacteria). If not a prokaryote then it just wouldn't be a cell because with eukaryote cells, if there are no chromosomes, there is no cell or life with that cell.
Does the chromosome number changes throughout the human life cycle?
No, the number of chromosomes remains constant throughout the human life cycle. Human cells have 46 chromosomes, with 23 inherited from each parent. This number is maintained through cell division and reproduction.
T is not easy to observe individual chromosomes during the interphase because?
Only during the division stages of a cells life will chromosomes form. During Interphase the cells DNA is in the unorganized form of chromatin.
When do chromosomes duplicate in a cells life?
When there joined with a male chromosomes and a female chromosomes
In a cells life cycle when to chromosomes duplicate?
Interphase

Do animal cells have a chromosomes?
Yes, as a matter of fact, all living that reproduce via mitosis or meiosis will form chromosomes. Chromosomes are only formed during these ways of reproducing. At all other parts of a cell's life, chromosomes are stringy matter called chromatin.
Which stage of a cells cycle do the chromosomes replicated?
Interphase. Cells spend the majority of the time in interphase, where they grow and perform their life functions.
What is the vehicle which transport the chromosomes from each parent to create a new human life?
The vehicle that transports the chromosomes from each parent to create a new human life is the sperm cell from the father and the egg cell from the mother. During fertilization, these two cells combine to form a zygote with a complete set of chromosomes.
Do chromosomes make copies of themselves?
Yes, chromosomes make copies of themselves through a process called DNA replication. During cell division, each chromosome is duplicated to ensure that each daughter cell receives an identical set of genetic material.
At what point in the cell life cycle is the best for photographing?
The interphase stage, specifically during the G1 phase when the cell is preparing for DNA replication, is ideal for photographing cells. This is because the cell's structures are visible and distinct during this phase before the DNA condenses into chromosomes during mitosis.
How are haploid and diploid related?
Haploid refers to having only one set of chromosomes, while diploid refers to having two sets of chromosomes. Body cells are diploid, while sex cells are haploid. In humans, diploid cells have two sets of 23 chromosomes for a total of 46, and haploid cells have one set of 23 chromosomes.

When are human cells diploid?
Human cells are diploid during the majority of their life cycle, including in somatic cells. This means they have two sets of chromosomes, one from each parent. The only exception is in reproductive cells (sperm and egg cells), which are haploid.
