In sexual reproduction the offspring has similar genetics and look of those of the parents. In asexual reproduction, it will look like the one parent, but it won't have the parent. The parent would have split in two and created two daughter cells, but when they make buds of them they have one child and on parent. Hope I helped! ;)
The answer is c)11 because copper has 11 valence electrons
When you're dealing with scientific notation (especially when you use an order of operations such as adding on it), it's important to know that you cannot add 10^2 to 3 (for example).
(3 x 10^5) + (5 x 10^8)
When adding exponents, you're only adding the exponents together and not changing the original number (10).
5 + 8 = 13
We now have a sum of 3x5 x10^13
Multiply 3 by 5 to get your new expression.
3 x 5 = 15
15 x 10^13 is what we're left with.
Your answer is A.)
I hope this helps!
Answer:
Explanation:
According to the experiment, the very nucleus of the atom is conformed by protons and neutrons, whereas electrons are diminute and have low mass in comparisson to protons and neutrons. So then, the nucleus accounts for the size and the mass of the atoms.
Answer: 207.24
Explanation: Atomic mass = no of protons + no of neutrons
1) 82 protons, 122 neutrons , mass number= 82+122 = 204
2) 82 protons, 125 neutrons, mass number= 82+125 = 207
3) 82 protons, 124 neutrons, mass number= 82+124 = 206
4) 82 protons, 126 neutrons, mass number= 82+126 = 208
Average atomic mass of an element = 
Average atomic mass of given element = 
The approximate atomic mass of lead is 207.24.
