Dogs have 37 pairs of chromosomes. As with pairs of shoes, the number of pairs is multiplied by 2 to get the total number of chromosomes in a dog's body cells. Therefore, the total number of chromosomes in a dog's body cells is 76. Sex cells, (sperm or eggs) have half of the pair, so would have 34 chromosomes. ________ The above is incorrect, dogs have 78 chromosomes meaning they have 39 pairs.
No. The total number of chromosome pairs differs by Organism.

There are four pairs of electrons around the central carbon atom of methane. These pairs each consist of one electron originally from the carbon and one from the hydrogen atom bonded to it.Though the question only considers the outer shell of electrons, as that is the only shell used for bonding, it may be useful to remember that in methane the carbon atom has a total of ten electrons around it, due to its two inner electrons.
There will be a total of 10 lone pairs of electrons. In NI3, each I will have 3 lone pairs (total of 9) and the N will also have 1 lone pair, for a grand total of 10 lone pairs.
There are 12 pairs of cranial nerves, which make a total of 24 cranial nerves. These nerves emerge directly from the brain and are responsible for various sensory, motor, and autonomic functions in the head and neck.
