The arctic fox is uniquely adapted to its environment with white fur for camouflage, a small nose and ears and warm coat to prevent heat loss and strong paws for running and hunting. Which statement best describes how the arctic fox population may have adapted to its environment over time?
Choose the correct answer.
Foxes were bred to meet human needs for white fur.
Foxes developed smaller ears and noses in response to their cold climate. They were able to survive and pass this trait on to their offspring.
Foxes changed their fur to white to hide from predators and disguise themselves from their prey. They were able to survive and pass this trait on to their offspring.
Variation existed in the traits of the fox population. Foxes with smaller ears and noses were able to stay warmer and were more likely to survive and reproduce to pass their genes on to offspring. Over time, the fox population showed a shift to smaller ears and noses.
Answer:
D

The Canadian lynx and the snowshoe hare have a predator-prey relationship. You will use two sets of population data and present them in a single graph.1.Using the second picture below,label the x-axis ‘‘Year of Study’’.Label the x-axis with data listed in the first picture.
2.Based on the sizes of the numbers for each population, create a scale on the two separate y-axes.
From the markings that you had written and erased on your graph, it seems that you already have an idea of what you're supposed to do. Is it that you're having trouble scaling your graph on the provided sheet given the particular data? Or do you have a conceptual question with respect to the instructions?
I've provided the image of the graph according to my understanding of the instructions as stated in 1 and 2, and I've also attached the corresponding Excel spreadsheet that I used to create the graph. While the blank grid that you've attached doesn't scale identically to my graph, it should be possible to transpose the necessary elements into your grid to an acceptable approximation.
That said, please feel free to let me know if you have any clarifications, comments, or questions.

In what direction do substances diffuse across the cell
membrane?
Answer:
Since diffusion moves materials from an area of higher concentration to the lower, it is described as moving solutes "down the concentration gradient." The end result of diffusion is an equal concentration, or equilibrium, of molecules on both sides of the membrane.

When a person bends a glow stick a small chamber inside it breaks releasing a substance that reacts with other substances inside a glow stick the reaction takes place causing the glow stick to glow. What type of energy transformation is this
Answer:
B i have done this before and it went on my tounge
Explanation:
The energy transformation in a glow stick is a chemical to light energy transformation.
What happens when the chamber inside the glow stick is bent?When the chamber inside the glow stick is bent, a small glass vial containing a chemical mixture breaks, and the chemicals inside mix with each other. This chemical reaction results in the production of light energy in the form of a glowing light stick.
The chemical reaction inside the glow stick involves the oxidation of a dye molecule, which releases energy in the form of light. The dye molecule is activated by the energy released from another chemical reaction that occurs between hydrogen peroxide and a phenyl oxalate ester. This chemical reaction releases energy in the form of heat, which excites the dye molecule and causes it to release light.
Therefore, the energy transformation in a glow stick involves the conversion of the potential energy stored in the chemicals inside the glow stick into light energy. This is an example of a chemical to light energy transformation.

Which of the following energy producing technologies can be beneficial to soil quality
A. Biomass
B. Solar
C. Wind
D. Oil
Answer:
Both solar energy and wind energy are beneficial to soil quality. They are not using fossil fuels that both harm the soil with digging and fracking, but also are not being burnt which harms the air and can create acid rain. Both solar and wind are using nature to benefit the world. As long as the sun keeps burning and the world turning, we will continue to be able to use them.
