Yes. Odd times odd is odd. Odd times even is even. Even times even is even.
By definition the diploid number of chromosomes is 2 times the number of chromosomes, and 2x is always even.
its always an even number....im pretty sure.
if you multiply an even number by 5 then it will always end in 0 but if you multiply an odd number by 5 then it will always end in 5.
No. In fact, you NEVER get an odd number.
Yes, an even number plus an even number is always even. Also, and odd number plus an odd number is always even.
The diploid number is always even because it contains two complete sets of chromosomes. Since there is two sets you split the diploid number in half. Two times any number is always even.
Yes because at least one of the consecutive numbers will be even, and if you times anything by an even number, the answer will always be even
A positive number times a positive number is always positive. A negative number times a negative number is always positive. Therefore, any square number will be positive. Any number to the fourth power (a square times a square) will always be positive. And so on.
Two odd numbers always sum to an even number. Always. Two even numbers always sum to an even number, and an odd number and an even number always sum to an odd number.
No. A given number need not even be divisible by a given prime.
Not always true because 2 times 13 = 26 which is an even number
