A scientist wrote a paper titled “Directional Selection in Action” after observing a population of mice for 15 years. The mice typically preferred to eat berries, although a few would also eat insects. After a drought in year 3, the scientist observed that more mice were eating insects. By year 10, most of the mice in the population ate insects in addition to berries. Which best describes her article?

Answers

A scientist wrote a paper titled “Directional Selection in Action” after observing a population of mice for 15 years. The best describes her article is her title is accurate because one extreme is favored.

What is scientific research?

A scientific research is research on a specific topic to collect the proofs and information that can be used in a scientific advancement.

The options attached here:

her title is accurate because two opposite extremes are favored.
her title is accurate because one extreme is favored.
she should change her title because she is observing stabilizing selection.
she should change her title because selection cannot be observed.

Thus, the correct option is 2. her title is accurate because one extreme is favored.

Explain why an ecological pyramid is smaller at the top than at the bottom

Answers

Because energy is wasted as heat, there is less energy available as food for organisms at each level above so ecological pyramid is smaller at the top than the bottom.

What is Ecological pyramid?

.An ecological pyramid is a graphical representation of the relationship between diverse living organisms at various trophic levels.

These pyramids have the shape of true pyramids, with the widest base and the lowest trophic level, i.e., producers, covering it.

The following trophic level, i.e. main consumers and so on, is occupied by the next trophic level.

The uppermost level of an energy pyramid has the fewest animals since it has the least amount of energy.

Most ecosystems only have four trophic levels since there isn't enough energy to support another at a certain point.

The energy produced by the plants is distributed to the a pex predator in the amount of 0.01 percent.

As a result, it makes logical that the pyramid's tiers grow smaller and smaller as you progress up the pyramid.

#SPJ2

The ecological pyramid is a diagram that shows the very much like amounts of energy or matter contained within each level. That's why it is shaped smaller at the top than at the bottom because the bigger it is the more the organisms are there are. So the bottom has more living organisms and the top has less.

LeeAnn wants to organize her data from researching the effect of hours of sunlight on plant growth to see if there is a trend in the data. Which would be the best way for LeeAnn to display her data for analysis so she can make predictions about the amount of light needed for maximum growth?in a line graph

in a data table

in an area graph

in a pie graph

Answers

The best way for LeeAnn to display her data for analysis so she can make predictions about the amount of light needed for maximum growth would be in a line graph.

A line graph is a chart that displays quantitative values over a period of time. A line graph is commonly used to display trends in a dataset and to evaluate how the data has changed over time. The line graph is made up of a horizontal x-axis and a vertical y-axis and each axis is labeled with a data type. In a line graph, the data points are plotted and are later joined by a line. The direction of the lines across the graph produces patterns that show the relationship between all the different variables in a dataset.

The best way to plot her data would be a line graph. With a line graph she would most easily explore the relatonship between all the different variables that play an effect in the growth of plants. Doing this, she would be able to maximize her data visually.

Answers

The correct answer is (b) improve transboundary ecosystem health.

The main goal of this mission was to improve the transboundary ecosystem by improving the health in the U.S border and to make it consistent by the help of sustainable development. It includes a variety of area that has to maintained. The air, water and land contamination has to be removed to improve the overall environmental health.

The US - Mexico Border 2012 Program's goal is to improve the transboundary ecosystem health. The purpose of such program is really focused on revitalizing the ecosystem, specifically the environment. Its goal is to reduce the contamination in the air, land and especially water.
