What is the relationship between natural selection and population?Natural selection can cause microevolution (change in allele frequency), which causes fitness-enhancing alleles to become more common in the population. Fitness is a measure of reproductive success (how many offspring an organism leaves for the next generation, relative to others in the group).
Another factor that limits the growth of populations is densification. This means that a large number of individuals present at the same time in the same area reduces the availability of resources for the population as a whole, increasing the mortality rate and reducing reproductive success.

The diameter of a cell is 40 um. You want to make a model of this cell where 1 cm represents 0.5 um. What would be the diameter of the model cell?
Answer:
The diameter of the model cell would be 80cm.
Explanation:
We know that 1 cm represents 0.5 μm, but we need to know how many centimeters are 40μm. To do so, we apply the simple rule of three:
So if 1cm= 05μm, 40μm would equal to how many centimeters?
1cm X 40μm = 80cm
0.5μm
We can see that the diameter of the model cell would be 80cm.

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.

1. Fungi
2. Plants
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.

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.
