The answer should be A. It takes a very small amount of mass to produce a lot of energy which is displayed in Einstein's equation E=mc². E is the amount of energy given off when some mass is converted into energy.
E=the energy given off, m=the mass turned to energy (I think this is sometimes referred to as the mass defect), and c=the speed of light. Nuclear reactions do not fallow the law of conservation of mass since some of the mass is converted into energy.
I hope this helps. Let me know if anything is unclear.
The answer is A; it shows that the number of rabbits increase as the times increases
Not very often, but sometimes, the language gives away the question. This is one such instance.
Look at A. Is digestion a bad thing? It shouldn't be. Otherwise you run marathons with gobs of food not being broken down and providing energy.
Not A.
Not C. Do you like yogurt? If you don't do you know someone who does? Is yogurt for you/them a bad thing. Bacteria here are good. Again, not C.
Not D. Waste is bad. It's a problem. Getting rid of it is good. Again not D.
There's only one left.
B <<<< answer. Who would like to get strep throat. It's a fate for your worst enemy.
B <<<< answer.
Sample cost = $15.796

Given
Mass = 2 g
Density = 0.718 g/ml
Cost = $5.67 per mL
Required
Cost
Solution
The density : the ratio of mass and volume
Can be formulated :
Density (ρ) = m : V
The volume of the liquid :
V = m : ρ
V = 2 g : 0.718 g/ml
V = 2.786 ml
Sample cost :
= 2.786 ml x $5.67/ml
= $15.796
Answer:
According to the law of conservation of mass, the mass of the reacting substances is equal to the mass of the product formed during a reaction.
