Answer:
valence electrons an element has in its outer shell, the easier it is to complete.
The most electron shells an element has, the easier it is to fill its outermost shell.
Explanation:
Non metals atoms bond to other elements by sharing or completing the valance electrons in other element. This is easily made when the other element lacks a small number of electrons, for example with Hydrogen it has 1 valance electron because of that it is easier to bond with other elements.
Answer:
The correct answer is - option a. It should be testable in a valid period of time
Explanation:
A thought that presents a temporary clarification about a phenomenon observed by a scientist is a hypothesis. The fundamental highlights of a good scientific hypothesis are: testability and falsifiability
A testable scientific hypothesis should answer the logical question. This is one that can be checked valid or bogus utilizing the information gathered or the experience gained.
a good scientific hypothesis must be testable and falsifiable. We should have the option to test the hypothesis utilizing the techniques for science and in the event that you'll review Popper's falsifiability rule, it must be conceivable to accumulate proof that will disconfirm the theory on the off chance that it is surely false.
Thus, the correct answer is - option a. It should be testable in a valid period of time
Answer: It would be similar to veins
Explanation:
Answer:
0.1% of energy
Explanation:
Energy flow: From the whole quantity of energy that reaches the earth's surface, autotroph organisms or producers absorb only 0.1 or 1%.
From the input of solar energy begins a unidirectional energy flow through all the organisms in the ecosystem, from autotrophs to heterotrophs, until it is dissipated in the environment.
At each trophic level occurs an energy transfer to the next, with only 10% being usable in each of them. This assessment is called "The 10% rule". As a general rule, only about 10% of the energy stored as biomass at one trophic level, per unit time, ends up as biomass at the next trophic level, in the same unit of time.
If wheat transferred 10% of the energy to mice, and of that 10% mice transferred 10% of the energy to hawk, then the percentage of energy transferred from the first trophic level to the third equals 0.1%.
10% (1st TL-2nd TL) / 10% (2nd TL - 3rd TL) = 0.1% (1stTL - 3rd TL)
<em>TL = Trophic level </em>
