When the sound reaches the brain I assume it processes and you assume a sound to what is making the sound. Like fire alarms for example, when we here that specific sound we know to react by evactuating.

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.
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

Which type of species produces many offspring, each of which has a small chance of surviving to maturity?
Specialist species
Generalist species
r-selected species
K-selected species
Answer:
r-selected species
Explanation:
r-selected species are those that emphasize high growth rates, typically exploit less-crowded ecological niches, and produce many offspring, each of which has a relatively low probability of surviving to adulthood (i.e., high r, low K). A typical r species is the dandelion (genus Taraxacum).
Answer: its not r-selected species

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.

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.

Scientists are interested in measuring the effect of pollution on the water quality of a stream. They will use observations of various bottom-
dwelling insects, or macroinvertebrates, collected in the stream as indicators of the physical, chemical and biological conditions within the
stream. Which of the following best describes why macroinvertebrate sampling can be used to assess the overall health of a stream?
Macroinvertebrates live in an aquatic ecosystem for a long enough time to show the chronic effects of pollutants, and many
tend to remain in the same area throughout their life span
B
Macroinvertebrates migrate long distances to feed or reproduce, and they have a low tolerance to pollutants.
Macroinvertebrates are top predators, so they are often used in determining whether toxins will bioaccumulate or
biomagnify in an aquatic environment
D
Macroinvertebrates can be collected to evaluate the effect of various test parameters such as dissolved oxygen, nitrites, and
pH at the time that the sample was taken

Scientists are interested in estimating the effect of pollution on the water grade of a stream. They will use statements of various bottom-dwelling insects, or macroinvertebrates, contain in the stream as hands of the physical, chemical, and biological conditions within the stream, Thus option "C" is correct.
What are some of the advantages of biological monitoring of macroinvertebrates in a stream?Macroinvertebrates merge the marks of short-term environmental deviations.
Most species have a complicated life cycle of about one year or more. Liable life phases will respond fast to stress; the overall community will respond more slow.
Thus, option "C" is correct, Macroinvertebrates are top predators, so they are often used in defining whether toxins will bioaccumulate or biomagnify in an aquatic environment.

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.
