Which transgenic organism has been used to clean up oil spills?.
Answer: The correct answer is bacteria
Explanation: Confirmed correct
Bacteria have been genetically modified to clean up oil spills.
Bacteria have been genetically engineered to clean up oil spills due to their natural ability to break down hydrocarbon compounds found in oil. These bacteria are often referred to as "oil-eating" bacteria or hydrocarbon-degrading bacteria. Genetic modification enhances their capabilities to efficiently degrade and metabolize the oil components, making them more effective in cleaning up oil-contaminated environments.
These genetically modified bacteria are designed to produce specific enzymes that can break down complex hydrocarbon molecules found in crude oil and petroleum products. The enzymes secreted by these bacteria help to speed up the degradation process, converting the oil into less harmful substances that can be naturally assimilated into the environment.
When these genetically modified bacteria are introduced into oil-contaminated areas, they can proliferate and colonize the contaminated sites. As they metabolize the hydrocarbons, they effectively reduce the concentration of oil pollutants, aiding in the remediation of the affected environment. The use of genetically modified bacteria for oil spill cleanup offers several advantages, including targeted and efficient degradation of oil, reduced environmental impact, and potentially faster recovery of affected ecosystems.
It's worth noting that while the use of genetically modified organisms (GMOs) for environmental cleanup has shown promise, it also raises considerations about potential unintended consequences, such as the introduction of new genetic material into ecosystems and the impact on non-target organisms. Therefore, careful evaluation and risk assessment are essential before deploying genetically modified organisms for environmental remediation projects.

Which statement best describes the effect of texture on absorption of radiant energy?
Rough and smooth surfaces do not absorb energy.
Rough and smooth surfaces affect the absorption equally.
Rough surfaces absorb more energy than smooth surfaces.
Rough surfaces absorb less energy than smooth surfaces.
Rough surfaces absorb more energy than smooth surfaces because of its irregular shape and low reflectance.
Describes the effect of texture on absorption of radiant energy?
Rough surfaces are better absorbers as well as emitters of heat energy than smooth surfaces because smooth surface is a good reflector and a poor absorber so its emissivity is low.
So we can conclude that Rough surfaces absorb more energy than smooth surfaces because of its irregular shape and low reflectance.

Vicki Arroyo: Let’s prepare for our new climate
Briefly summarize what Arroyo explains her talk will be about.
What are the three examples Arroyo gives for how we can prepare for the massive impact climate change will have on all of us?
According to Arroyo, how can we better prepare and adapt to violent storms and floods?
According to Arroyo, the second thing we need to prepare for is heat and droughts. What are some ways in which people are better preparing to handle these effects of climate change?
Although Arroyo does not mention the term “watershed,” it was discussed in the unit as being closely related to and impacted by drought and floods. Please discuss how the watershed relates to drought and heat. How might Arroyo have integrated the term watershed into her talk?
The third example that Arroyo talks about is rising sea levels. What are some of the ways rising sea levels can be highly dangerous and damaging? What are some of the solutions being implemented to prepare for the future?
At the end of her talk Arroyo says, “Adaptation’s too important to be left to the experts.” Explain what she means by this, if you feel this is a valid point and why.
A watershed is an area which drains to a common body of water, one of its main functions is to temporarily store and transport water from the land surface to the water body and ultimately (for most watersheds) onward to the ocean. So she can include watershed as drought preventive method in her talk.
What is climate change?Climate change is defined as a change in global or regional climate patterns, in certain a change apparent from the mid to late 20th century onwards and attributed largely to the increased levels of atmospheric carbon dioxide produced by the use of fossil fuels.
Rising sea level can be reduce by following solutions:
Beaches and dunes can act as a natural wall and reduce the impact of storm surge. The bigger the beach or larger the dune, the more water can be stopped from reaching homes and roads.
Coastal communities can restore natural infrastructure, that can act as a buffer against storms and coastal flooding. Natural structures such as barrier islands, and coral reefs, mangroves, and salt marshes can work alone.

Alfred adler proposed that older siblings, who start out as the focus of their parents’ attention but must share that attention once a new child joins the family, compensate by becoming_____.
Answer:
overachievers
Explanation:
The youngest children, according to Adler, may be spoiled, leaving the middle child with the opportunity to minimize the negative dynamics of the youngest and oldest children. Despite popular attention, research has not conclusively confirmed Adler’s hypotheses about birth order. (Spielman et al. 2020).
According to Alfred Adler, older siblings, who start out as the focus of their parent’s attention but must share that attention once a new child joins the family, compensate by becoming overachievers.
Adler believed that older siblings often feel displaced and insecure when a new baby arrives. They may feel like they are no longer special or important, and they may worry that their parents will love the new baby more than they do.
To cope with these feelings, older siblings may become overachievers. They may strive to excel in school, sports, or other activities in order to prove their worth to their parents. They may also become very responsible and independent, in an effort to take on more of the parental role.
Of course, not all older siblings become overachievers. Some may become withdrawn or rebellious, while others may simply adapt to the new situation and continue to develop in a healthy way.
However, Adler's theory suggests that overachievement is a common coping mechanism for older siblings who feel displaced by a new baby.

B. because striated muscle tires easily
C. because striated muscle is voluntary, allowing you to stop your

D. because striated muscles can be trained, allowing you to

Answer:
D. because striated muscles can be trained, allowing you to strengthen your heart with exercise
Explanation:
Striated muscles convert chemical energy into physical work. You can make your striated muscles stronger with exercise. This helps the heart perform its function better and more efficiently.
Striated muscle does not have digestive enzymes and does not play a role in digestion. Striated muscles are very strong, and besides, that doesn't show why its beneficial anyway. It is impossible to voluntarily stop your heartbeat. If you did, you'd die.
Therefore, the best answer is D.

Which of the following is not a benefit of energy conservation? Increases energy abundance for all Decreases dependence on fossil fuels Creates more power plants for energy Decreases greenhouse gas emissions
Answer:
Creates more power plants for energy
Explanation:
Creating more power plants is not a form of energy conservation, but, rather, a means of producing more energy for consumption. Energy conservation will lead to an increase in energy abundance, will decrease dependence on fossil fuels is the rate of fossil fuel consumption decreases, and will decreas greenhouse gas emissions due to a decrease in fossil fuel production and combustion.
The following that is not the benefit of energy conservation is creating more power plants for energy. The correct option is C.
What is energy conservation?Energy conservation means using the energy and energy sources efficiently so that there will be no waste of energy. The conservation of energy is necessary because there are limited sources of energy and if the sources will run out, there will be no energy to use.
The benefits of energy conservation are it will increase the stored energy and decrease the dependency on fossil fuels. Because they create pollution and if a lower amount of fossil fuel is used, there would be fewer greenhouse gases would be emitted.
Thus, the correct option is C. to create more power plants for energy.
