13. Which method for producing electricity has had the most negative impact on the
atmosphere?
A burning fossil fuels
B. controlling nuclear fission
C. harnessing wind with windmill farms
D. using hydroelectric dams to block rivers
Helpppp please
Answers
Answer:
The answer is A.
Explanation:
One of the downsides to electricity is the way it is generated. Usually, electricity was generated through Coal which as a fossil fuel was pivotal in releasing large amounts of carbon dioxide into the atmosphere.The method for producing electricity that has had the most negative impact on the atmosphere is A) burning fossil fuels.
What is the consequence of burning fossil fuels ?Burning fossil fuels, such as coal, oil, and natural gas, releases large amounts of carbon dioxide and other greenhouse gases into the atmosphere. These gases trap heat in the Earth's atmosphere, leading to global warming and climate change.
In addition, burning fossil fuels also releases other pollutants, such as sulfur dioxide and nitrogen oxides, which can contribute to acid rain and other environmental problems.
While all methods of producing electricity have some impact on the atmosphere, burning fossil fuels has had the most negative impact due to the sheer amount of greenhouse gases and other pollutants that are released during the process.
While there are efforts to reduce the negative impacts of burning fossil fuels, such as developing cleaner burning technologies and transitioning to renewable energy sources, the continued use of fossil fuels for electricity generation remains a significant challenge for addressing climate change and reducing air pollution.
In addition to greenhouse gas emissions, burning fossil fuels also produces other pollutants, such as sulfur dioxide and nitrogen oxides, which can contribute to acid rain and other environmental problems.
Therefore, extraction, transportation, and storage of fossil fuels can also have negative environmental impacts, such as oil spills, groundwater pollution, and habitat destruction.

Counterclockwise rotation of the flagellum causes a bacterial cell to swim or ______ towards a stimulus, interrupted by clockwise rotation in which the cell ______ and changes its course.
Answers
Counterclockwise rotation of the flagellum causes a bacterial cell to swim or run towards a stimulus, interrupted by clockwise rotation in which the cell tumbles and changes its course.
How does a bacterium respond to stimuli?A bacterium is a unicellular organism that posseses a structure called flagellum.
Flagellum in bacteria is a long, whiplike proteinaceous appendage, used for locomotion.
However, a counterclockwise rotation of the flagellum causes a bacterial cell to swim or run towards stimulus. This rotation is interrupted by a clockwise rotation of the flagellum that causes the bacterium to tumble.

Some cons of having invasive species include capable of causing extinction to native species. Also, taking away possible food or eating eggs from native plants and animals. Lastly, invasive species can take away all sorts of habitats in all different ecosystems.
People that might care about this situation includes any normal citizens and biologists. This is true because they both have a big say in changing other peoples thoughts and can notice their surroundings. If everyone cared about this problem many invasive issues would go away and many places would have their native species back in order to save them from extinction.

Answers
Carbon moves from the biosphere to the geosphere is the correct statement.
How carbon moves in this scenario?
Carbon moves from the biosphere to the geosphere because the dead organism has carbon in its body and when it is decomposed the carbon goes into the soil.
So we can conclude that carbon moves from the biosphere to the geosphere is the correct statement.

Answers
Answer:
frost
Explanation:
Frost is the deposition of water vapour from humid air or air containing water vapour on to a solid surface. Solid frost is formed when a surface, for example a leaf, is at a temperature lower than the freezing point of water and the surrounding air is humid.
In sub-freezing air, water vapour changes directly to ice without first becoming a liquid. This is how frost and hoar frost form on the ground or other surfaces. Another example is when frost forms on a leaf.

Lake Victoria in East Africa is home to many species of fish called cichlids. In 1954 the predatory Nile perch was introduced to Lake Victoria. The Nile perch became the dominant fish species in the lake by the mid-1980s. The number of cichlid species in the lake decreased as the Nile perch population increased. The perch preyed heavily on cichlid species that fed on algae and debris on the bottom of the lake. Algae in the lake increased, and oxygen levels decreased. The surface area of the gills of some cichlid species has increased in over 20 years.
A. Increased gill surface area has allowed the cichlids to change their diet and avoid competing with the Nile perch.
B. Increased gill surface area has allowed the cichlids to be camouflaged and avoid being eaten by the Nile perch.
C. Increased gill surface area has allowed the cichlids to leave Lake Victoria and establish populations in nearby bodies of water.
D. Increased gill surface area has allowed the cichlids to better absorb the limited oxygen in the water.
Answers
Answer:
D. Increased gill surface area has allowed the cichlids to better absorb the limited oxygen in the water.
Explanation:
As the Nile perch fed on cichlid species that feed on algae, algae growth increased in the lake. The algae absorbed more oxygen, leaving less for the fish. Those with larger gills were able to absorb oxygen more efficiently, and were able to survive.

Explanation:
Why did the students leave the amylase and starch solutions in the water bath for five minutes in step 3
Answers
Answer:
Each enzyme functions at an optimum temperature. Below the optimum temperature, the enzyme's function slows, and will eventually become inactive. Above the optimal temperature, the enzyme's activity will slow. Too far above the optimum temperature and the enzyme becomes denatured (its shape changes) and it can no longer function. Amylase is the enzyme that breaks starch (amylose) down into maltose. The amylase and the starch were placed in the water bath to allow the reaction to occur at amylase's optimum temperature of 37 C.

During tubular reabsorption, most of the water, glucose, and ions in the glomerular filtrate are reabsorbed into the blood whereas urea is not.
What is tubular reabsorption?Tubular reabsorption refers to.the process whereby minerals and water are reabsorped from the glomerular filtrate into the blood.
The renal artery carries mineral rich, oxygenated blood from the heart to the kidneys whereas the renal veins carry deoxygenated blood from the kidneys back to the heart.
Blood in the renal arteries contains red blood cells, white blood cells, large blood proteins, glucose, water, ions, and urea.
Filtrate in the kidney tubules contains water, glucose, ions, and urea.
Filtrate not reabsorbed is urea.
Urine contains urea, ions and water.
Blood in the renal veins contains red blood cells, white blood cells, large blood proteins, glucose, water, and ions.
