A loud alarm attached to a metal fence begins to ring. Student X has her ear against a pole of the fence while student Y stands away from the fence, as shown below. Both students are the same distance from the alarm. Which of the following statements explains what happens in this situation?
A. Student Y hears the alarm at a higher pitch because gases are denser than solids.
B. Student X hears the alarm at a higher pitch because solids are denser than gases.
C. Student Y hears the alarm first because sound travels faster in gases than in solids.
D. Student X hears the alarm first because sound travels faster in solids than in gases.
Student X hears the alarm first because sound travels faster in solids than in gases.
Speed of soundSound is a wave, as such, sound waves are able to travel across long distances. The speed of sound is greatest in solids since the gases have a high density owing to the fact that the molecules are closely packed.
Now, we can infer from this that student X hears the alarm first because sound travels faster in solids than in gases.

what are the similarities of mitosis and miosis?
Answer:
Mitosis and meiosis are two processes by which eukaryotic cells may divide and share several similarities: They are both preceded by interphase (which includes DNA replication) They both divide according to a common pathway (prophase → metaphase → anaphase → telophase) They both split their cells via cytokinesis.
Explanation:
Answer:
Explanation:
Mitosis and meiosis are the two ways by which cells reproduce. As a result, they share several steps in their respective processes. Meiosis adds another division and a step that mixes the genetic material from the parent cells, but in both cases the cell must duplicate its DNA, pull it apart into two sets, place the sets on each end of itself, and then divide down the middle. Both mitosis and meiosis produce fresh new cells based on their parent cells' genes.
Humans can take up available space, disrupt systems, or change water supplies in an ecosystem. What conclusion can you make about how human activities affect the flow of energy and matter in an ecosystem? (best answer will be marked brainliest depending on how many answers) NEED BEFORE 10PM
Answer:
Human activities affect the flow of energy and matter in an ecosystem and alter the energy balance in ecosystems through the unsustainable nature of what they do. The energy flow is affected in several ways as a result of pollution, overpopulation, deforestation, burning fossil fuels, etc. Such changes have stimulated soil erosion, climate change, causing water unfit to consume, poor quality of air and so on. When humans cause a change in the energy balance, they impact the ability of the ecosystem to respond and adapt to changes in the environment. It is like getting a cut, but it never heals and grows bigger instead.
Answer:
i guess that humans harm ecosystems
Explanation:
they pollute water take up the extra space and disturb the animals and their homes

Answer:C .Bacteria have cytoplasm and ribosomes which are common with the cells of other living organisms. Some bacterias have whip-like which is flagellum which helps bacteria cells have prokaryotes which mean the DNA is not being held with the nucleus like cells of plants and animals.
Explanation:Bacteria have cytoplasm and ribosomes which are common with the cells of other living organisms. Bacteria cells are unicellular organisms which have cells wall but they do not have the nucleus.
They contain DNA materials which are made of chromosomal and plasmids. Some bacterias have whip-like which is flagellum which helps bacteria cells have prokaryotes which mean the DNA is not being held with the nucleus like cells of plants and animals.

1. According to the diagram, what do you notice about the wolf population?
2. Compare the wolf and the elk population numbers. What do you notice about the elk population as the wolf population increases? Give an explanation for the change in elk population numbers.
3. What do you notice about the aspen, cottonwood, and willow tree populations in relation to the elk and wolf populations? Give an explanation for the change in population numbers for these trees.
Answer:
Explanation:
At least 136 wolves were killed in the park between 1914 and 1926. By the 1940’s wolf packs were
seldom reported in the park. In fact, by the mid-1900’s wolves had been nearly eliminated not just from
Yellowstone but from the lower 48 states entirely.
Reintroduction was not without controversy as there were, and still are, many stakeholders involved in the
Yellowstone area, each with unique concerns. However, in the twenty years since the reintroduction of the
wolves, scientists have noticed many positive changes to the park ecosystem. This set of activities seeks to
introduce students to the trophic cascade that has occurred in the park and the positive changes in the
ecosystem since the reintroduction of a top predator – the wolf.

What is NOT a
method used
to genetically
modify
organisms?
A. making holes in
the cell to get the
new DNA into the
Cell
B. having bacteria
engulf a cell with the
new DNA
C. using a plasmid
to insert new gene
into the cell of the
organism
Answer:
B
Explanation:
- electroporation or microinjection actually pokes holes in the cell membrane so DNA can be introduced directly into the cell. Microinjection requires the use of a fine needle to deliver nucleic acids to individual cells.
- you can insert DNA fragments or genes into a plasmid vector, creating a recombinant plasmid. This plasmid can be introduced into a bacterium by way of the process called transformation. Then, because bacteria divide rapidly, they can be used as factories to copy DNA fragments in large quantities.
Thus, leaves question B as the Not method

Every member of a particular rodent species is found within a population living in a forest ecosystem. These rodents eat a variety of
plants and live in hardwood trees. Their population growth is limited by the amount of space they have available.
Human construction in the area is steadily reducing the habitat of the rodent species. Which of the following will most likely occur if
the species' habitat continues to be destroyed?
OA. The species will experience population growth.
OB. The limiting factor of the population will change.
OC. The population will use less resources and stay the same size.
OD. The species will eventually become extinct.
Answer:
The species will eventually become extinct.
Explanation:
If a species habitat is constantly being reduced and destroyed by a numberous number of things such as human construction, then the species will reduce and eventually go extinct. This is due to the fact that a species habitat is everything to them, it gives them a place to feel comfortable and provides them with food and other neccesities. The species would eventually become extinct is the place they need to leave which is their habitat is constantly being destroyed day by day.

D.a little more energy.
Answer:
C. much less energy
Explanation:
First, warm water needs to be heated and heat requires energy. Roughly 75 percent of the energy required to do a load of laundry goes into heating the water. Using cold water saves energy, putting less pressure on electricity grids.
What’s the answer????
Answer:
A
Explanation:
The relative distance between two consecutive feild lines is inversely proportional to the strength of the magnetic field. Since we observe that in region B (near the poles), the magnetic field lines are stacked together, while in region A, they have considerable perpendicular distance between them, which makes A weaker.
My friend (Let's call her "Riley" for safety reasons) says Red Pandas' are Raccoons and I say they are their own family, How do I prove to "Riley" that they aren't Raccoons? Should I use bone structure or should I use something else?
Red pandas are members of the bear family, Ailuridae. While raccoons are in the family of Procyonidae. Both the bear family and the raccoon's family are closely related.
What do you mean by Raccoons?Raccoons may be defined as greyish-brown American mammals that possess a foxlike face with a black camouflage and a ringed tail.
DNA analysis is a tool that differentiates red pandas are not raccoons. The genetic analysis suggests that the red pandas and the raccoons originated from a common ancestor, but both are not the same.
Therefore, it is well described above.
