Genes
A tribble's body cell typically contains 40 chromosomes.
23 i think -- There's no such thing as "a DNA. But it works the other way around: DNA doesn't contain chromosomes, but chromosomes contain DNA. A person has 23 chromosome pairs: 46 chromosomes. One (pair) of which decides gender. Some people aren't perfect and have 47 chromosomes. Maybe other 'combinations' exist too.
Sex cells (better known as gametes) being product of meiosis have single set (haploid number) of chromosomes whereas body cells have diploid number. Thus, 22 pairs of autosomes and one pair of sex chromosomes (XY), thus 46 chromosomes are present in our body cells. The gametes (sex cells) contain only 23 chromosomes in each.
Humans have 46 chromosomes. This means they will produce sex-cells (sperm and ovum/egg) which have 23 chromosomes.
Genes found on chromosomes contain the DNA codes for proteins. These proteins are essential for various biological processes and functions in the body.
Bacteria contain one circular chromosome (and several tiny circular plasmids), some slime molds contain hundreds of thousands of linear chromosomes. Other organisms contain various numbers of chromosomes depending on the species.
A tribble's body cell typically contains 40 chromosomes.
Sex cells contain half the number of chromosomes that body cells contain.
chromosomes contain mitochondria, which acts just like a battery.
Diploid
No, each egg and sperm cell contain half the number of chromosomes found in a normal body cell, which is 23. When an egg and a sperm cell combine during fertilization, they create a new cell with the full set of 46 chromosomes.

No. DNA doesn't contain chromosomes. Chromosomes are DNA.
If the gametes contain 25 chromosomes, the organism will have 50 chromosomes in its body cells. This is because during fertilization, the gametes (sperm and egg) fuse to form a zygote, which will contain a total of 50 chromosomes, with 25 from each parent.
You get the other 23 from the opposite sex. The semen and the egg combines and gets 46 chromosomes. If each gamete contained 46 chromosomes, the zygote would contain 92 chromosomes.
Skunks have a total of 38 chromosomes in their body cells. This includes 18 pairs of autosomes and one pair of sex chromosomes. As with most mammals, these chromosomes contain the genetic information necessary for their development and functioning.
Human cells contain forty-six chromosomes each. An exception to this is gametes (oocytes and sperm), which contain twenty-three chromosomes each.
