A city is supplied by water from local wells. The city discharges its treated wastewater into the ocean.The city uses 25,000 liters of water per person per year. Precipitation falls in the amount of 25,000 liters per person per year.



Is the city using its water supply in a sustainable manner?

A)yes
B)no

Answers

Answer 1

Answer:

B)no

Explanation:

Sustainable use of water means use of water to fulfil various human needs for water without having any negative impact on the environment.

The sustainable use of water allows a minimum of 20 to 50 litres of daily water per person to fulfil their water needs, that means 600 litres maximum per person per year but in the given situation the city uses 25,000 litres of water per person per year.

This shows that people in the city are not using water sustainably which is causing a fall in precipitation.

Hence, the correct answer is "No".

Where does the H+ come from that makes ATP synthase work?

Answers

Answer:

Electron Transport Chain

Explanation:

Gizmos Cell Respiration

The H+ that's vital in making ATP synthase work comes from the electron transport chain.

The electron transport chain can be found in the mitochondria. It is a series of protein complexes that are able to transfer electrons from the electron donors to the electron acceptors.

It should be noted that the transfer of the electrons from the electron donors to the electron acceptors is done through the redox reactions. This is illustrated in the H+ that made the ATP synthase work.

Each year, the United States' federal costs exceed the anticipated national budget. In fact the last time that the United States government was able to end a fiscal year without accruing more debt was in 1960. This means that due to excessive spending and compounding interest accrued, the United States' national debt has escalated astronomically over the past several decades.

How do limiting factors determine the carrying capacity of an ecosystem ?

Answers

Answer:

Limiting factors determine carrying capacity. The availability of abiotic factors (such as water, oxygen, and space) and biotic factors (such as food) dictates how many organisms can live in an ecosystem. Carrying capacity is also impacted by the availability of decomposers.

Explanation:

Carrying capacity is determined by limiting variables. Limiting factors can be divided into two categories: those that depend on the density and those that don't.

What are the limiting factors?

Limiting factors can be divided into two categories: those that depend on the density and those that don't. These names are accurate in their meanings.

No matter how big or little, expanding or contracting, the population is affected by density-independent causes. For instance, regardless of the density of any one population, a wildfire that burns through a dense forest in the Everglades has a significant effect on every population in the area.

The majority of density-independent limiting variables fall into the abiotic (nonliving) group, which includes wildfire. Hurricanes, pollution, and seasonal climate extremes are other density-independent variables.

Therefore, Carrying capacity is determined by limiting variables. Limiting factors can be divided into two categories: those that depend on the density and those that don't.

Explanation:

The importance of preserving Earth's Biodiversity remains on the idea that every single living organism that existed here on Earth is an example of how Nature can express itself. This means that we as humans can learn with every mechanism that has been developed through millions of years and apply to our self been.

Answer:

all of these

Explanation:

The preservation of the biodiversity of the Earth is important for many ecological, economic, and cultural reasons.

Biodiversity increases ecosystem stability for a given type of ecosystem because greater species diversity ensures natural sustainability of all life forms within the ecosystem. Ecosystems are also highly interconnected and the removal of even a few species can cause ecosystem disruption.

The organisms of Earth's ecosystems provide services that humans cannot replicate. These ecosystem services include the generation of soil that is typically done by microbial and animal species, the maintenance of air quality that is done by plants, the decomposition of wastes that is done by the Earth's decomposers, and the maintenance of water quality that is done by wetland ecosystems.

Chap wanted to see if planting seeds deeper into the soil had an effect on plant height. He took ten containers and planted radish seeds at varying depths. He used the same type of soil, kept the plants in the same location, and gave them each 20 milliliters (mL) of water each day. Then, he measured the height of the sprouts every day for two weeks. What are the independent (test) and dependent (outcome) variables in Chap's experiment?

Answers

Answer:

Independent variable: Planting depths of seeds

Dependent variable: plant height

Explanation:

Independent variable in an experiment is the variable that the experimenter changes or manipulates in order to bring about a measurable response. In this experiment involving the planting of radish seeds at varying depths, the DEPTH AT WHICH THE SEEDS ARE PLANTED is the independent variable.

Dependent variable is the variable that is measured in an experiment. It is the variable that responds to the changes made to the independent variable. In this experiment, the HEIGHT of the radish plants measured is the dependent variable.

B.) Two study sites with fluctuating water temperatures, similar coral communities growing at similar depths, with similar water nutrient profiles

C.) Two study sites with the same temperature profile, different coral communities growing at different depths, with different water nutrient profiles

D.) Two study sites with stable differing water temperatures, similar coral communities growing at similar depths, with similar water nutrient profiles

Answers

It’s d because it makes the most sense

The statement that reveals the best study designs and may yield the most conclusive results is as follows:

Two study sites with stable differing water temperatures, similar water nutrient profiles, and similar coral communities growing at different depths.

Thus, the correct option for this question is A.

What is Hypothesis?

In experimental biology, the hypothesis may be defined as a testable statement about the relationship between two or more variables or a proposed explanation for some observed phenomenon. It is basically an assumption that is made based on some evidence.

According to the context of this question, the hypothesis that best demonstrates the most conclusive results for the above experiment is the stable differing water temperatures, similar water nutrient profiles, and similar coral communities growing at different depths. This is because the depths of the coral may vary with respect to the nutrients available in an aquatic ecosystem.

Therefore, the correct option for this question is A.
