"Cow pasture" is the other feature in the landscape among the choices given in the question that could be the reason for the high levels of phosphorus. The correct option among all the options that are given in the question is the second option.

The other options are incorrect because:

Cars produce carbon monoxide emissions, not phosphorus

Solar Panels don't produce waste from use

Forest ecosystems efficiently cycle nutrients

The hypothesis for Tonya's experiment is "If distance of a race increases, the amount of time needed to run the race will increa
WINSTONCH [101]

The dependent variable is what changes because of the independent variable, while the independent variable is what is purposefully changed by the experimenter, since it is the variable that is being tested.

So, in this problem, you are purposefully changing the distance of the race to see whether or not the amount of time taken to complete the race will change because of the varying distances.

This means that purposefully changing the distance of the race is the independent variable that is being tested and that the amount of time that the runner takes to complete the race is the dependent variable because it changes due to the independent variable.

Sorry for being so wordy.

In short,

Independent variable- the one that's being tested and that is purposefully changed.

Dependent variable- the one that changes because of the independent variable.

Hope this helps.

Why would a mutation in a somatic cell of a multicellular organism escape detection?
Mashcka [7]

When a somatic cell is mutated, none of the other cells in the organism mutate with it. Screenings usually detect mutations that are in numerous cells and not in just one. That is why a mutation in a somatic cell of a multicellular organism escape detection.

<h3>What are mutations?</h3>

A mutation in biology is an adjustment to the nucleic acid sequence of an organism's, virus's, or extrachromosomal DNA. DNA or RNA can be found in the viral genome. Errors in DNA replication, viral replication, mitosis, meiosis, or other types of DNA damage (such as pyrimidine dimers from exposure to ultraviolet radiation) can result in mutations.

These errors can then lead to error-prone repairs, particularly microhomology-mediated end joining, error-causing repairs, or errors during replication. Due to mobile genetic elements, mutations can also result from the insertion or deletion of DNA segment.

Think of a change that can occur to an ecosystem and the populations that live in that area. In what ways can the different popu
Alex73 [517]

Answer:

There are several environmental factors that causes changes in the ecosystem and the population of that area such as invasive species, extreme weather, land use change, pollution and disease.

Lets take invasive species as environmental factor. Introduction of invasive species can cause a huge change in the ecosystem and affects the native population in that area. it increases the competition for food resources and decreases the survival rate of their preys.

For example: Water hyacinth (Eichhornia crassipes). It is an invasive plant species that has very bad impact of native population as well as other population, like it reduces biological diversity, oxygen loss, decreased phytoplankton productivity,  eliminate plants that animals use for nesting, and alter animal communities by blocking access to the water.

Thus invasive population can affect population by reducing biodiversity, water shortages, decreasing availability and quality of key natural resources, disturb the food chain and can cause natural calamities.

Invasive species affect the resources that native species are using and that decreases the carrying capacity of the native population as it disturbs the whole food chain.
