Answer:
Generally, consumers only receive 10% of the energy from what they eat. So, if the grass had 220,000 kcal of energy, then the cow would receive 10% of that - 200kcal. And then when a human eats the cow, it will only receive 10% of the cow's energy. This is because within a food chain, energy is lost as organisms use their energy to survive - like moving and producing heat (if endothermic). So consumers do not get 100% of their food's energy. Hope this helps a little.

Answer:
Thomson to decide that atoms were not indivisible, in reality are actually composed of smaller parts? Thomson used a scanning tunneling micrograph to capture images of atoms. Thomson used a beam of negatively charged particles. Thomson used only the experimental results of other scientists
Explanation:
Answer:
Option C
Explanation:
A) A chemical equation is simply the symbolic representation of a chemical reaction using the form of symbols and formulae. Thus, option A is not the answer.
B) A product is the substance that shows at the end of a chemical reaction. Thus, option B is not the answer.
C) Law of conservation of mass in chemistry states that even in chemical reactions or physical transformations, that mass cannot be created nor destroyed. Which means that mass is conserved. This has nothing to do with chemical change demonstrated chemical reactions. Thus, option C is correct.
D) reaction rate is the speed that a chemical reaction occurs. Thus, options D is not correct.
Answer:
graph a shows acceleration and b does not
Explanation:
the velocity increases in graph a, but stays constant in graph b
1000 milligrams = 1 gram
Lethal Dose:
10 grams = 10,000 milligrams
Step 1:
Lethal dose divided by mg per can.
10,000 mg / 1.71 mg= 5847.95 ounces
Step 2:
5847.95 oz / 12 oz per can= 487.32 cans
Step 3:
Round up to 488 cans because we have to buy whole cans.
Hope this helps! :)
