Explanation:A circuit with total resistance of 20Ω has a potential difference of 12V and current of 1.2A. calculate energy done in 5 minutes
Answer:
Overuse of antibiotics is creating stronger germs. Some bacteria are already "resistant" to common antibiotics. When bacteria become resistant to antibiotics, it is often harder and more expensive to treat the infection. Losing the ability to treat serious bacterial infections is a major threat to public health.
A mutation can be a change of just one nucleotide in a gene. How can a mutation create a new allele of a gene:
Answer:
A mutation can create a new allele of a gene by changing the DNA sequence of the gene. A gene is made up of a sequence of nucleotides, and a mutation can occur when one of these nucleotides is altered. For example, a single nucleotide change can result in a different amino acid being incorporated into the protein that is produced from the gene. This can affect the structure and function of the protein, which can lead to new traits in the organism that carries the mutated allele.
If the mutation occurs in a gamete (a sperm or egg cell), it can be passed on to the next generation. If the mutation provides a selective advantage to the organism, it may become more common in the population over time, leading to the creation of a new allele. Over many generations, accumulation of mutations can result in the evolution of new species with unique traits and characteristics. Therefore, mutations are a key driving force of genetic diversity and evolution in populations.

In what two way so plan cells use the sugar made in photosynthesis
In order to give the plant life-sustaining energy and to create other kinds of organic molecules, plant cells employ the sugar produced during photosynthesis in these two ways. C and D are the right answers.
Why does photosynthesis occur?In order to convert light energy into chemical energy that may be released to power an organism's activities through cellular respiration, plants and other lifeforms use a process called photosynthesis.When a plant is photosynthesising, its leaves capture light energy. Water and carbon dioxide are converted by plants into glucose, a sugar, using the energy of the sun.For energy and the production of cellulose and starch, among other materials, plants utilize glucose. To build cell walls, cellulose is employed. So, the right answers are c and d.For more information on photosynthesis kindly visit to

How do the prevailing westerlies impact weather patterns in mid-latitude regions?
The prevailing westerlies are winds that blow from west to east in the middle latitudes, between 30° and 60° north and south of the equator. These winds are important in shaping weather patterns in mid-latitude regions, including North America, Europe, and Asia.
The prevailing westerlies are part of a global circulation pattern of the atmosphere known as the Ferrel Cell. As warm air rises at the equator and moves toward the poles, it cools and sinks at around 30° north and south. This sinking air creates a zone of high pressure, which leads to the development of the prevailing westerlies.
The prevailing westerlies have several impacts on weather patterns in mid-latitude regions:
1. They bring moist air from the ocean to the coast, leading to the development of rain and snow.
2. They help to distribute heat from the equator toward the poles, which helps to moderate temperatures in mid-latitude regions.
3. They can bring cold air from the poles toward the equator, leading to the development of cold fronts and storms.
4. They can influence the formation and movement of storms, including cyclones and hurricanes.

typically lays three eggs each year. If disturbed, it will often abandon its nest. A snowy
plover and its nest are shown below.
Piping Plover
a. Compare the birth rate (number of eggs hatched) to the death rate in a
population of snowy plovers that is increasing in size. Provide evidence to
support your answer.
In a population of snowy plovers that is increasing in size, the birth rate (number of eggs hatched) would be higher than the death rate.
This is because an increasing population indicates that more individuals are surviving and reproducing successfully than are dying or failing to reproduce.
Snowy plovers typically lay three eggs each breeding season, and if undisturbed, the eggs will hatch and produce new offspring. However, if disturbed, the plovers may abandon their nest, which could result in the loss of the entire clutch of eggs.
Therefore, if the population of snowy plovers is increasing, it suggests that a sufficient number of eggs are hatching and producing new individuals to offset any potential loss due to disturbance or predation. In this scenario, the birth rate would be higher than the death rate, leading to an overall increase in population size.

Make a prediction: what if the capybara could find a better way to evade the anacondas? What do you think would happen within this ecosystem?
If capybaras were able to find a better way to evade anacondas in their ecosystem, it is likely that their population would increase, as fewer capybaras would be preyed upon by anacondas. This increase in capybara population would have a cascading effect on the ecosystem, as capybaras are an important food source for many other predators in the region. The decrease in anaconda predation on capybaras could also lead to a change in the behavior of the anacondas, as they may need to switch to alternative prey species or alter their hunting strategies to be successful. Additionally, with more capybaras around, there could be increased competition for resources such as food and water, which could lead to changes in the behavior of other herbivores in the ecosystem. Overall, any changes to the balance of predator-prey interactions within an ecosystem can have far-reaching effects, and it would be interesting to observe how such changes would play out in this specific ecosystem.

Compare the ATP available to cells when oxygen is present versus when it is absent. How might this help explain why brain and heart functions are so quickly affected when a person cannot breathe?
DO NOT COPY AND PASTE. EXPLAIN IN YOUR OWN WORDS.
When oxygen is present, cells undergo aerobic respiration, which produces ATP molecules more efficiently compared to anaerobic respiration.
What are aerobic and anaerobic respiration?Aerobic respiration occurs in the mitochondria and involves the breakdown of glucose into carbon dioxide and water, with the help of oxygen. This process yields a net gain of 36-38 ATP molecules per glucose molecule.
In the absence of oxygen, cells undergo anaerobic respiration, which is less efficient than aerobic respiration and produces only 2 ATP molecules per glucose molecule. Anaerobic respiration involves the breakdown of glucose into lactic acid.
When a person cannot breathe, oxygen supply to the brain and heart is cut off, leading to a shift from aerobic to anaerobic respiration. This results in a rapid depletion of ATP molecules and a buildup of lactic acid, leading to cellular damage and eventual organ failure.
Moreover, the brain and heart have high energy demands, and any disruption in the ATP supply can quickly affect their function. Without a steady supply of ATP, the brain and heart cells cannot maintain their normal electrical activity, which can lead to seizures, cardiac arrhythmias, and even death.

Write a complete scientific explanation to account for why the heavier ball caused more flour to spread out. Be sure to include the relationship between amount of mass and amount of kinetic energy in your explanation, and include a claim, evidence, and reasoning.
The heavier ball spread out more flour because it had more kinetic energy due to its greater bulk, according to the claim. Reasoning: As the heavier ball is rolled over the flour, it gives the flour particles greater kinetic energy.
Why does a heavier ball spread the flour out more?Larger, faster balls have more kinetic energy than smaller, slower-moving balls. As the ball lands, this energy is transmitted to the flour and cocoa powder.
Are heavier items more gravitationally influenced?Because the downward force on an object is equal to its mass times the acceleration component, g, a heavier object would feel a stronger downward force.

Answer:
Explanation:
The carbon cycle is the process by which carbon moves between the Earth's oceans, atmosphere, land, and living organisms. It is a natural and essential cycle that helps regulate the Earth's climate and support life.
In the carbon cycle, carbon is exchanged between the atmosphere, oceans, and land through a variety of processes. For example, photosynthesis by plants and other organisms removes carbon dioxide from the atmosphere and converts it into organic matter. This process is known as carbon fixation. Respiration by living organisms, including plants, animals, and microbes, releases carbon dioxide back into the atmosphere.
Other natural processes involved in the carbon cycle include the decomposition of organic matter by microbes, the weathering of rocks, and the movement of carbon through the ocean via ocean currents. Human activities, such as burning fossil fuels and deforestation, have also significantly impacted the carbon cycle by releasing large amounts of carbon into the atmosphere.
Overall, the carbon cycle plays a critical role in regulating the Earth's climate and supporting life on the planet. Understanding the carbon cycle is essential for addressing global climate change and managing natural resources sustainably.

Please help

Answer:
Melanin absorbs dangerous UV rays that can do severe skin damage. But melanin can't absorb all the UV rays, and some people don't have much melanin in their skin.
Explanation:
The sun is by far the strongest source of ultraviolet radiation in our environment. Solar emissions include visible light, heat and ultraviolet (UV) radiation. Just as visible light consists of different colours that become apparent in a rainbow, the UV radiation spectrum is divided into three regions called UVA, UVB and UVC. As sunlight passes through the atmosphere, all UVC and most UVB is absorbed by ozone, water vapour, oxygen and carbon dioxide. UVA is not filtered as significantly by the atmosphere.Ozone is a particularly effective absorber of UV radiation. As the ozone layer gets thinner, the protective filter activity of the atmosphere is progressively reduced. Consequently, the people and the environment are exposed to higher levels of UV radiation, especially UVB.
Ozone depletion is caused by human-made chemicals released into the atmosphere and will continue until the use of chlorine and bromine compounds is drastically reduced. International agreements, in particular the Montreal Protocol, are gradually succeeding in phasing out the production of ozone-depleting substances. However, the long life span of the chemicals already released will cause ozone depletion problems to persist for many years to come. A full recovery of the ozone level is not expected until 2050.Most UV-A does reach the surface, but UV-A does little genetic damage to tissues. UV-B is largely responsible for sunburn and skin cancer, though it is mostly absorbed by ozone before reaching the surface. Levels of UV-B radiation at the surface are especially sensitive to the amount of ozone in the stratosphere.
