Using the words "selection pressure" and "fitness", explain how natural selection causes populations to change over time.
Answer:
Environment and competition is the leading cause of evolution. It's an instinct to want to live, but trying to survive is difficult when other animals have the same goal. An ecosystem is a cycle, but every generation of this ecosystem slightly changes, and so do the animals. Every bug that has fitness can start overpopulating the ecosystem, leading to a surge of resources for what preys on the bug. Now bird's population goes up, so do other animal populations. Or the bug becomes an invasive species, and birds are being hunted too often to decrease the population.
In a different scenario, bugs are evolving because of the selection pressure that the environment is giving them. The birds have become better over the generation, and now have a more suited beak to catch the bug off the ground. The bug population maybe be decreasing, but the ones who live through the crisis are populating with bugs that certain gene that helped them out. But it's not over, the bug population isn't declining but it wasn't as big as it was before. The bird will find more ways to find and capture the bugs. But then bugs will keep surviving through the selection pressure and become much harder to find since they figured out camouflage. The bug that was neon yellow was dying since they were easy to see. Now they can range from green to black to hide in the environment. Now the birds are facing the selection pressure, it's a cycle.

3. Bacteria
Answer:
3.bacteria
Explanation:
The majority of nitrogen fixation happens when bacteria converts atmospheric nitrogen(N2) into ammonia(NH3).
hope it is helpful to you
The majority of nitrogen fixation happens when bacteria convert atmospheric nitrogen (N2) into ammonia (NH3). Bacteria live in symbiotic associations such as Rhizobium, but some live freely and fix nitrogen.
How is atmospheric nitrogen fixed?The atmospheric nitrogen is fixed by bacteria, which convert the atmospheric nitrogen into ammonia. There are many bacteria involved in this process.
Some bacteria live in symbiotic relationships with the roots of legume plants and capture nitrogen. Example: Rhizobium converts the nitrogen into ammonia, and the nitrogen enters living creatures when they eat the legumes. The leguminous plant makes the soil more fertile due to this process.
This process is aided by bacteria such as Azotobacter and Clostridium. Azotobacter is an aerobic bacteria, while Clostridium is an anaerobic one. The nitrogen is important for living organisms, as nitrogen is important for DNA, RNA, and protein synthesis.
Hence, Bacteria is the correct answer, as bacteria convert the atmospheric nitrogen (N2) into ammonia (NH3). option 3 is correct.

North Carolina has more wind off its shore than any other Atlantic Coast state. How could this resource be best utilized to reduce carbon emissions and provide cleaner energy for the state?
Answer:
C. Offshore wind farms could be constructed to generate wind energy, which reduces fossil fuel use throughout the state.
Explanation:
Option C is the correct answer.
Actually, wind energy is another alternative to fossil fuel. If North Carolina has more wind off its shore, then it is best to utilize it to reduce carbon emissions. It will help produce cleaner energy for the state.
So, the best way it can be utilized to reduce carbon emission is by constructing offshore wind farms in order to generate wind energy. This wind energy will help to reduce fossil fuel emissions.
Answer:
C. Offshore wind farms could be constructed to generate wind energy, which reduces fossil fuel use throughout the state.
Explanation:
Wind power is an excellent option for North Carolina homes, farms, businesses, schools, and utilities interested in producing clean, independent electricity.
If the population of moths is found to have 100% dark colored individuals, would it be possible for them to survive if humans came and cleaned up the pollution on the trunks of the trees; returning them to a light colored bark?
Why or why not?
Explain your reasoning.
Answer:
Decrease occur in the population.
Explanation:
It would be impossible for dark colour moth to survive if humans cleaned up the pollution on the trunks of the trees and returning them to a light colored bark because the dark colored moths can easily be seen by their predators. The dark colour of trunk helps the dark colored moths to hide from their predators so if the black colour of the trunk are turn into light colour so there is decrease occur in the population of black colored moths.

Wallace's line is a deep-water boundary that separates islands that differ greatly in their fauna, despite their close proximity and similar climate. Accordingly, these islands are assigned to two different biogeographic realms, each of which has a large number of species that are restricted to that location and found nowhere else in the world. These species are considered ____________. Group of answer choices
Answer:
endemic
Explanation:
Endemism refers to a state in which a species/population is native to a particular geographic area (e.g., an island), although if these organisms are also found elsewhere, then they are not considered to be endemic. Endemic species are generally vulnerable to suffer extinction when their habitats are irreversibly damaged, and therefore they represent biodiversity indicators that can be used as a reference to create protected 'hot spots' and centers of endemism. Some examples of endemic species include Tasmanian devils (living in the island state of Tasmania) and koalas (living in the southeast and eastern sides of Australia). On the other hand, cosmopolitan species are widely distributed and therefore they can be found in different geographic areas around the world.
A tissue sampler that is being used for a medical procedure is placed inside a saline solution. Unknown to the medical team, the saline solution is hypertonic. Deduce what will happen to the cells within the tissue sample
Answer: Water will leave the cell and the cell will shrink.
Explanation:
Osmosis is the net movement of water from an area of low to high concentration of solutes through a semipermeable membrane. If none of the compartments contains solutes, then the water moves in either direction between the compartments. However, if we add a solute to one of the compartments, this will affect the probability of water molecules leaving that compartment and moving into the other compartment. The ability of water to move into or out of a cell is called tonicity. The tonicity of a solution is related to its osmolarity, which is the total concentration of all the solutes in the solution. A solution with low osmolarity has few solute particles per liter of solution, whereas a solution with high osmolarity has many solute particles per liter of solution. When two solutions with different osmolarities are separated by a membrane permeable to water but not permeable to solutes, water diffuses from the side with lower osmolarity to the side with higher osmolarity. So, solutions can be:
Hypotonic: The extracellular fluid has a lower osmolarity than the fluid inside the cell, it is hypotonic with respect to the cell, and the net flow of water will be into the cell. Hypertonic: The extracellular fluid has a higher osmolarity than the cytoplasm of the cell, it is hypertonic with respect to the cell and water will flow out of the cell. Isotonic: The extracellular fluid and the cell have the same osmolarity so there is no net movement of water.If a cell is placed in a hypertonic solution, water will leave the cell and the cell will shrink due to the difference in pressure and may even die from dehydration.

What best explains the variation in tree heights in the topical rain forest
Answer:
B. Competition for light and moisture
Explanation:
Plants grow towards sunlight which is necessary for photosynthesis, of which they utilize sunlight, carbondioxide, and moisture to manufacture their food. In the tropical rain forest, competition is intense among plants for sunlight and moisture.
The trees/plants that are able to get enough sunlight and moisture gain advantage over others as they grow bigger and taller, as the rest struggle to get some sunlight and moisture. The canopy of taller trees usually cut-off sunlight from teaching shorter trees, thereby making availability of sunlight to the shorter trees quite limited. As a result of this, we have variations of trees with different height in the tropical rainforest.

When people eat simple carbohydrates, they get _____.
A. energy very quickly
B. energy slowly, over a long period of time
C. information for how to build enzymes
D. material to build muscles
Answer:
In short The Correct Answer Is A. Energy Very Quickly, Which is the most common thing gotten from carbohydrates is energy although your body can also save the energy gained from carbohydrates for later the carbohydrates itself is processed very quickly compared to slowly...
Explanation:
Carbohydrates are a main source of energy for the body; they can be metabolized to ATP fast or slow depending on the body’s needs. Insulin brings glucose from the blood into the cells to be used for energy. The cell can either use it right away for energy or store it to use later.
Carbohydrates and Blood Sugar. When people eat a food containing carbohydrates, the digestive system breaks down the digestible ones into sugar, which enters the blood. As blood sugar levels rise, the pancreas produces insulin, a hormone that prompts cells to absorb blood sugar for energy or storage.
Some people can survive on few carbohydrates because the body can convert protein into carbohydrates to be used for energy. When people eat too many carbohydrates, often in the form of simple carbohydrates, they can gain weight because the body stores the extra carbohydrates as fat.
