predation
competition
commensalism
parasitism

Answer:
Competition
Explanation:
They are both eating the same food, which means, in a given ecosystem, they essentially have to "share" food. If only one of the species existed in the ecosystem, they would have access all the forest mice. When two species eat the same food, they have to compete to make sure they can get to the mice first.

Sea otters tend to inhabit the shores of the pacific (sometimes rivers, ponds, or lakes), a favorite habitat is the kelp forests on the coast of California.

This is a clear sign of intelligence, and they classify as mammals. Otters stay in groups led by a dominant male, but sometimes females will leave with their babies, or males will depart in search of their own group to manage.

what do similar banding patterns tell us living environment?
Answer:What do banding patterns indicate?
Banding patterns are patterns of light and dark transverse bands on chromosomes. The light and dark bands become apparent by staining the chromosome with a chemical solution and then viewed under a microscope. These bands describe the location of genes on a chromosome.
Explanation:
Why are banding patterns important?
Banding Patterns Reveal the Structural Details of Chromosomes. Without any treatment, structural details of chromosomes are difficult to detect under a light microscope.
What does each stained band represent?
bands are the horizontal "bars" which are actually stained DNA molecules embedded in the gel. As the DNA molecules migrate through the gel, they are sorted according to their molecular weight, so that each band represents DNA of a specific molecular weight.

What procedure did you use to complete the lab
The Lab Name Is Energy Transfer.
Answer: Energy transfer could come through condoctours (metal, or copper) to another object to power a bulb, speaker or any other electrical gizmo. (This can get a brainliest answer)
Answer:
Energy transfer is a process of passing energy into a source that lacks it, like a lightbulb. Energy can be transferred through conductors, that pass through the energy to the goal (lightbulb). Conductors are available inside of the cables you use to connect the power source and the lightbulb together, they are mostly metals, since they are good conductors. When you turn on your lightbulb, with it connected to the cable which is connected to the energy source, the energy passes through the conductor into the goal and turns on your lightbulb. There are other products to prevent energy transfer, they are called insulators, they stop energy transfer and keep it stored inside of them. An example of insulator is silicon, it stores the energy instead of transmitting it and keeps it stored inside without electrifying anyone when touching it.
