Which of the following could be reasons why population sizes may reach and maintain plateaus? Select the three (3) that apply.
fewer deaths
limits in food supply
competition with other species
increased birth rates
competition for space
major storms
Answer:
the answers are a, b, and ,d
The following could be reasons why population sizes may reach and maintain plateaus are fewer deaths, limits in food supply and increased birth rates.
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.

a.The outer layer of the Earth is divided into plates that move due to convection currents under the surface.
b.If the amount of daylight increases plant growth, then plants will have higher rates of growth during the summer.
c.For every action or force in nature, there is an equal and opposite reaction.
Answer:
3. theory → a. The outer layer of the Earth is divided into plates that move due to convection currents under the surface.
2. hypothesis → b. If the amount of daylight increases plant growth, then plants will have higher rates of growth during the summer.
1. law → c. For every action or force in nature, there is an equal and opposite reaction.
Explanation:
THEORY
The scientific theory explains facts or the cause of natural phenomena and makes predictions about them. It is based upon direct observation and scientific methodology.
The theory is fundamental to science because it allows scientists to organize and understand observations.
HYPOTHESIS
A hypothesis is a prediction done by the researcher when trying to answer a problem question. It is a conjecture, which has not been verified yey, nor refused, and that requires corroboration. It is a possibility, but not a fact. The researcher performs the experiment and concludes if the hypothesis is rejected or accepted. The prediction must be objective, expressed in a comprehensive manner, and reflect a logical relation between the variables involved in the experiment.
LAW
Law is a statement that establishes a relationship between variables explaining the cause of natural phenomena. It is based upon empirical information and evidence obtained after many repeated experiments and observations. Many scientists agree with the statement and use it to perform a research project. A law cannot be changed.

Western and Eastern meadowlarks look very similar and it is difficult to tell them apart, until they sing. Their mating songs are quite different. The Western meadowlark has a melodious song, whereas the song of the Eastern meadowlark sounds more like a whistle. Even though their ranges overlap in the central United States, they do not interbreed and are considered two different species. How would speciation MOST LIKELY have occurred in these two species of meadowlarks
Answer:
The correct answer is - Reproductive isolation occurred through behavioral isolation.
Explanation:
Behavioral isolation is a type of isolation that takes place due to the beginning to develop different behaviors in populations of the same species which is not preferred by these different populations.
Due to this behavioral isolation, these populations show reproductive isolation and new species form. The most common example of behavioral differences is mating calls.

Plant viability depends on heterotrophs' capacity to mineralize vital components. All mammals and fungi are heterotrophs, as are the majority of opisthokonts and prokaryotes.
What are the different organism in an ecosystem?In ecosystems, biotic and abiotic factors—or nonliving components—coexist. Biotic factors include plants, animals, and other species. Abiotic factors include temperature and humidity in addition to rocks.
Aiding in the germination and distribution of various plant seeds throughout an ecosystem.
Chemoheterotrophs include herbivores, predators, scavengers, and decomposers.
Materials from chemoautotrophs and chemoheterotrophs are recycled by chemoheterotrophs and employed repeatedly in a complex web of life.
Therefore, Symbiotic connections between some organisms and autotrophs allow them to obtain organic carbon, such as corals.

Explanation: Climate change is causing the extinctions of species. But some species will have better chances of survive-al because they were created that way. So, humans for example will have a good chance of survive-al despite of climate change, because we are always innovating and changing, while most plants and animals, are used to one type of climate or region. Although there some cases of plants and animals that can adapt to any struggles of climate.

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.
