How does competition drive natural selection?
Answer:
Competition often occurs between members of the same species. This is called intraspecific competition. This is the type of competition that is the driving force behind natural selection within a species. Competition influences natural selection by the finite amount of resources available, those members of species best adapted to take advantage of the resources are more likely to reproduce and pass on their genes to the next generation.

Bats hunt using echolocation, in which they send and receive high frequency sounds to locate prey. When bats hear the sounds of others, they typically begin hunting in the same area. As the number of bats hunting in the area increases, individuals become more successful at locating and capturing prey. Some populations of bats live in areas with high levels of noise pollution, such as near heavily trafficked bridges. How might the hunting behavior of bats be affected by such an environment? A. Bats would be more likely to hunt in groups, so an individual's success in catching prey would increase. B. Bats would be better able to use echolocation, which would improve their ability to find prey. C. Bats would be unable to use echolocation, which would prevent them from finding any prey. D. Bats would be less likely to hunt in groups, so an individual's success in catching prey would decrease.
Answer: C) Bats would be unable to use echolocation which would prevent them from finding any prey.
Explanation: I believe it’s B because if there is a long of noise pollution it would interfere with there echolocation causing them to not be able to find prey.
Answer:
C. Bats would be unable to use echolocation which would prevent them from finding any prey.

Enzo works for a pharmaceutical company experimenting with new drugs. Currently, he is searching for a new treatment to help people with
atherosclerosis. This disease makes it difficult for blood to flow smoothly through the veins and arteries. Enzo would like to find something that
could naturally thin the blood. He believes that in just the right dosage, it might be able to thin human blood enough to lower blood pressure.
Considering the symptoms that it produces in animals, which plant would Enzo be MOST interested in?
A. elderberry
B. arrow grass
C. rhubarb
D. sweet clover
The plant that the Enzo should be most interested in is the elderberry. That is option A.
Treatment of atherosclerosisAtherosclerosis is a cardiovascular disorder that occurs when there is a build up of cholesterol in the blood and plaque in the walls of the artery.
The major effect of this disorder to the arteries is the difficulty of blood flow through the arteries and veins.
Elderberry is the common name for the flowering plant called Sambucus.
Recent studies have shown, using experimental animals, that elderberry juice may reduce the level of fat in the blood and decrease cholesterol. This would help to thin human blood enough to lower blood pressure.
Therefore, the plant that the Enzo should be most interested in is the elderberry.

1. What is some information about Cellular Respiration?
2. What is some information about Photosynthesis?
3. What are the connections between Photosynthesis and Cellular Respiration?
Answer:
1.cellular respiration, the process by which organisms combine oxygen with foodstuff molecules, diverting the chemical energy in these substances into life-sustaining activities and discarding, as waste products, carbon dioxide and water.
2.
Explanation:
Green leaves synthesize food woth the help of air, sunlight and water by a process called photosynthesis
3.Photosynthesis converts carbon dioxide and water into oxygen and glucose. Glucose is used as food by the plant and oxygen is a by-product. Cellular respiration converts oxygen and glucose into water and carbon dioxide.
THIS FOLLOWING ANSWER IS ONLY FOR QUESTION ONE:
Cellular respiration is what cells do to break up sugars to get vitality they can utilize. Cellular respiration takes in food and employments it to create ATP, a chemical which the cell employments for energy. More often than not, this process uses oxygen, and is called aerobic respiration. It has four stages known as glycolysis, Link reaction, the Krebs cycle, and the electron transport chain. This produces ATP which supplies the vitality that cells have to be compelled to do work. When they do not get sufficient oxygen, the cells use anaerobic respiration, doesn’t require oxygen. In any case, this process produces lactic acid, and isn't as productive as when oxygen is utilized.
Aerobic breath, the method that does utilize oxygen, produces much more energy and doesn’t create lactic acid. It too produces carbon dioxide as a squander item, which at that point enters the circulatory system. The carbon dioxide is taken to the lungs, where it is traded for oxygen. The rearranged equation for aerobic cellular respiration is:
[tex]C6H12O6 + 6O2 = 6CO2 + 6H2O + Energy (as ATP)[/tex]

What is climate change?Climate change is caused by the increase of greenhouse gases in the atmosphere, primarily carbon dioxide from burning fossil fuels. This increase in greenhouse gases leads to global warming, which in turn causes changes in temperature and weather patterns around the world. These changes have significant impacts on ecosystems and can lead to the extinction of many species. Climate change can cause more frequent and severe extreme weather events such as droughts, floods, and hurricanes.
Hence, the major environmental change that is occurring today that could cause the next mass extinction is climate change, which is the last option as climate change is the major environmental change.

2. Green roofs can improve air quality
3. Green roofs can absorb storm water and can release it slowly
4. Green roofs tend to increase number of roofing jobs
5. Green roofs are easy to install and maintain
Answer:
Explanation:
Enhanced stormwater management and water quality: Green roofs can reduce and slow stormwater runoff in the urban environment, and also filter pollutants from rainfall. Green roofs can retain nearly all storm-related precipitation during the summer months, with lower retention during the winter months (< 20%).
The benefits of green roofs are green roofs can improve air quality, they can absorb stormwater, and can release it slowly. The correct options are 2. and 3.
What are green roofs?A flat or slightly inclined roof may have a layer of flora grown on top of a waterproofing system, known as a "green roof." Vegetative or eco-roofs are other names for green roofs.
Extensive, intensive, and semi-intensive are the three basic subcategories. Improved stormwater management and water quality: Green roofs may filter pollutants from rain and minimize and slow stormwater runoff in metropolitan areas.
Nearly all storm-related precipitation can be captured by green roofs in the summer, but less so in the winter.
Therefore, the correct options are 2. Green roofs can improve air quality.

Ceratium fusus is a protist that is found primarily in coastal waters, especially around the coast of the United Kingdom. These organisms are unique because they can undergo a special chemical reaction at night that helps defend them against predators. It provides defense by attracting larger predators that prey on the organisms that eat Ceratium fusus. Which characteristic of Ceratium fusus is being described? photosynthesis glass-like cell walls bioluminescence chitin cell walls.
A chemical defense mechanism is called bioluminescence.
As mentioned in the reaction, Ceratium fusus undergoes a special chemical reaction at night which helps them defend themselves from predators. During this reaction, light is produced inside a living organism. However, this type of reaction does not produce heat although it does produce light.
What is bioluminescence used for?
The most well-known purpose of bioluminescence is to defend the organism against attacks by predators. This is because the light confuses or frightens predators.
Besides confusing the predator, the light can also alert large predators to approach the location of the organism, in this way this large predator will eat the predator that is threatening the organism which in our question, is Ceratium fusus.
Many marine organisms use the phenomenon of bioluminescence for their defense, in particular marine invertebrates, vertebrates, certain micro-organisms as well as certain fish and fungi.
Hence concluded that the bioluminescence characteristic of Ceratium fusus is being described.
