In a population of pea plants such as the one below, bees and other pollinators prefer to land on purple colored flowers. Over generations, more and more purple flowers successfully reproduce due to this pollinator preference. Which of the following statements accurately describes what is happening to the pea plants over time?
Question 2 options:
Natural selection causes evolution in the population of pea plants and leads to increased overall variation.
Natural selection causes evolution of individual pea plants and leads to increased overall variation.
Natural selection causes evolution in the population of pea plants and leads to an increase in favorable adaptations.
Natural selection causes evolution of individual pea plants and leads to an increase in favorable adaptations.
Answers
Answer:
Natural selection causes evolution in the population of pea plants and leads to an increase in favorable adaptations.
Explanation:
The flowers will evolve to keep that purple trait in order to continue their population growth, hence why it is not individual evolution but as a population. Also since the purple color is a favorable trait it will lead to an increase in favorable adaptations and will decrease variation.

18 The size of a mouse population in a natural
ecosystem tends to remain relatively constant due to
A. the cycling of energy.
B. the lack of natural predators.
C. the increased numbers of decomposers.
D. the carrying capacity of the environment.
Answers
Answer:
D- the carrying capacity of the environment.
Explanation:
The limiting factors also called as the carrying capacity of the environment keeps the size of a mouse population in a natural ecosystem constant. Therefore, option (D) is correct.
What is a limiting factor in a ecosystem?Limiting factors are physical, biological, and ecological conditions that:
(1) Limit the ecosystem's ability to sustain native plant and animal populations and to accommodate natural disturbances like floods;
(2) Limit the quality or availability of habitat that supports all life stages of native species; and
(3) Limit the ecosystem's ability to sustain the local tribal culture.
The only natural factor limiting the number of mice in the home is a scarcity of resources such as food. Therefore, The limiting factors also called as the carrying capacity of the environment keeps the size of a mouse population in a natural ecosystem constant.

True or False: In a box and whisker plot, 50% of the data is between Q1 and the median
Answers
Answer:
Minimum = 0%
Q1 (Lower Quartile) = 25%
Median = 50%
Q3 (Upper Quartile) = 75%
Maximum = 100%
That is true. In a box and whisker plot, Q1 is the first quartile (first 25% of the data) is between the lower quartile (Q1) and the median. The median is the middle, so 50% will fall between Q1 and the median. It's important to understand the various measures of central tendency and how they can be used to analyze the spread of data within a given set, which can provide valuable insights and understanding about the overall trends present within the data.

Deforestation increases precipitation. D. Tree roots improve soil water retention. Please select the best answer from the choices provided A B C D.
Answers
Deforestation increases the risk of floods in an area tree roots improve soil water retention.
Why does deforestation result in higher flood risk?When deforestation takes place, the top layer of soil can be dislodged – this is also known as soil erosion.
When the top layer of soil is unstable, it is unable to retain any of the water that falls on it, resulting in increased surface run-off, which, in turn, increases the risk of flooding.
Thus, option "D" is correct.

Based on the diagram, what would happen if Earth had no atmosphere?
Diagram of greenhouse effect showing the sun, atmosphere, and human activities that release greenhouse gases. The diagram shows that sunlight is reflected back to space by the atmosphere, absorbed at the surface, and reflected by the surface. Greenhouse gases trap heat from the sun. Examples of human activities include CFCs and haloalkane from refrigerators and aerosols, nitrous oxide from gasoline and agriculture, methane from cattle and fertilizer, and carbon dioxide from oil and coal.
Human activities would not release greenhouse gases.
Greenhouse gases would not trap heat from the sun.
Sunlight would not be absorbed at the surface.
Surface temperatures would be maintained.
Answers
Based on the diagram, we can confirm that if Earth had no atmosphere, Greenhouse gases would not trap heat from the sun.
Why would these gases not trap heat from the sun without the atmosphere?Greenhouse gases are located in the atmosphere, therefore, without it, they would not be able to trap the heat from the sun. Although high concentrations of these gases are a modern problem in global warming, these gases are a natural part of the earth and are necessary to maintain livable temperatures at the surface of the earth.
Therefore, we can confirm that if Earth had no atmosphere, Greenhouse gases would not trap heat from the sun.
