Answer:

B. A proton gradient drives the formation of ATP from ADP and inorganic phosphate via ATP synthase.

Explanation:

Light reaction of photosynthesis includes the splitting of water in the presence of sunlight and electron transfer from PSII to PSI via an electron transport system. During the transfer of electron through cytochrome of the electron transport system, the proton concentration gradient is generated across thylakoids. The proton concentration gradient is harvested to drive ADP phosphorylation by the catalytic site of ATP synthase accompanied by downhill movement protons through its proton channels.

Why can it be a disadvantage for a nation to depend on foreign oil?

Arte-miy333 [17]

Answer:

If a nation were to depend on foreign oil, if there were be an natural event to the country the nation is depending on that would cause a problem such as decreasement of oil or make it hard to export oil it would be hard to find an alternative efficiently. If there was to be a war or feud, or you eliminate an export to the country with the oil, they might stop sending oil.

How many trophic levels do most food webs have? Why? Relate your answer to the appropriate law of thermodynamics

Anton [14]

Answer:

Most food webs have between 4 and 5 trophic levels

Explanation:

Energy flow: From the whole quantity of energy that reaches the earth's surface, autotroph organisms or producers only absorb 0.1 or 1%.

From the input of solar energy begins a unidirectional energy flow. It passes through all the organisms in the ecosystem, from autotrophs to heterotrophs, until it is eventually dissipated in the environment.

There is an energy transfer from each trophic level to the next, and each level only uses 10% of this energy. 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. The rest of the energy is used by the organisms in their own metabolism or dissipated as heat to the environment.

The progressive reduction of energy determines the number of trophic levels, which, in general, turns to be between 4 and 5.

Factoring a death rate from natural causes and predation, the beetle population increases approximately 5% each year. Use the Ta

Alekssandra [29.7K]

The estimated population for each year will be:

11500

12075

12679

13313

13979

14678

<h3>How to calculate the population?</h3>

Given an estimated beetle population of 11,500, of which it is estimated to increase approximately by 5% each year, we can calculate the estimated population for each year as follows:

Year Calculation Est. Population

1st yr (current yr) 11,500

2nd yr 11,500*105% 12,075

3rd yr 12,075*105% 12,679

4th yr 12,679*105% 13,313

5th yr 13,313*105% 13,979

6th yr 13,979*105% 14,678

The above is how the table that shows the estimated population for each year.
