Answer
Evolution is basically just the process in which different types of organisms have devoloped.
Easier way of saying it:
The gradual development of something
usually from something simple to something complex.
Have a great day :)
Answer:
Evolution is the gradual change of characteristics and traits, that occurs within a species, over many generations.
Explanation:
Due to natural selection, some genes of a species can be passed on to their offspring, to increase chances of survival. This is because these new traits are enabling, the organisms who have them, to survive longer then the ones who don't, thus allowing them to procreate and have more offspring, who share that same trait.
This process can occur over several generations, and in turn, can really change a species.
Hope this helps. :)

What is the difference between Carbonia and Insularia Peppered moths?
Carbonia and Insularia Peppered moths are two distinct forms or subspecies of the peppered moth (Biston betularia). The main difference between these forms lies in their geographic distribution and coloration.
Carbonia Peppered Moth: Carbonia is a form of peppered moth that is predominantly found in industrial areas where pollution and soot are prevalent.
These moths have dark or melanic coloration, which provides them with camouflage against the darkened tree trunks that were common in industrialized regions. The dark coloration of Carbonia moths helped them evade predators and increased their survival rates in polluted environments.
Insularia Peppered Moth: Insularia is another form of peppered moth that is primarily found in non-polluted or rural areas.
These moths have lighter or speckled coloration, which allows them to blend in with lichen-covered tree trunks that are common in unpolluted habitats.
The light coloration of Insularia moths provided them with camouflage against their natural background, reducing predation risk.
The difference in coloration between Carbonia and Insularia Peppered moths is an example of industrial melanism, where moth populations adapted to their changing environment due to human industrial activities.

during what phase of cell division does nondisjunction occur?
Nondisjunction occurs during the phase of cell division called meiosis. Meiosis is a type of cell division that reduces the number of chromosomes in a cell by half, resulting in the formation of reproductive cells, also known as gametes.
During meiosis, homologous chromosomes, which carry the same genes, pair up and exchange genetic material through a process called crossing over. After crossing over, the chromosomes separate into two different cells. Nondisjunction occurs when one or both of the homologous chromosomes fail to separate properly during meiosis, resulting in an unequal distribution of chromosomes in the daughter cells. This can lead to cells with too many or too few chromosomes, which can cause genetic disorders such as Down syndrome. Cell division is the process by which a single cell divides into two or more daughter cells. It is an essential part of growth, reproduction, and tissue repair in all living organisms. There are two main types of cell division: mitosis and meiosis

How many amino acids could be specified if codons consisted of two nucleotides instead of three? What problem would this present for an organism making proteins using all 20 amino acids? I need help with the last part i dont undertsand
Answer:
This could result in a mutation.
Explanation:
A change in the DNA can affect the work of cells because it can cause a mutation; it can be a good mutation or bad. The three main mutations that occur are Insertion, Deletion and Substitution. Insertion is when DNA base(s) are added in, Deletion is when DNA base(s) are removed. Lastly, Substitution is when DNA base(s) are switched on. All of these mutations can have effects. These effects are Silent effect, Missence, and Nonsense. Silent effect is a mutation that does not change the sequence of amino acids in a protein. Missence is a mutation that causes the sequence of amino acids to change. This can cause incorrect protein folding and protein malfunction. Nonsense is a mutation that causes an early stop codon. This effect leads to a protein that is too small. Also a Frameshift can occur. Framshift is when the reading of a frameshift is moved over by one or more bases such that every subsequent amino acid changes. An example of a frameshift is THE CAT ATE THE RAT. If you insert an A at the Beginning this happens ATH ECA TAT ETH ERA T. IN Conclusion there are two Mutations that also play a role in this Point Mutation and Chromosomal Mutaion. Point Mutation is when a single DNA base is either substituted, inserted or deleted from the sequence. Chromocomal Mutation is when large pieces of a chromosome or an entire chromosome is either substituted, inserted or deleted.
16 amino acids could be specified if codons consisted of two nucleotides instead of three.
What do you mean by Codons?Codons may be defined as an arrangement of three consecutive nucleotides in a DNA or RNA molecule that codes for a specific amino acid.
A mutation may be responsible for such problems that would present for an organism making proteins using all 20 amino acids.
A synonymous mutation means that one base within the codon gets substituted for another. Even though the same amino acid is still produced.
It changes the sequences of nucleotide bases within the codon, but ultimately the coded amino acids remain the same.
Therefore, it is well described above.

Assignment 1: Evidence for Evolution
Patterns based on observations of fossils:
[Example:] The observation made by Darwin that living species of armadillo can be found in the same area of Argentina where fossils of extinct glyptodonts were reported. Both species are very similar, with the glyptodon being like a giant armadillo. This observation can be explained if the two species are evolutionary related, thus belonging to the same lineage of species but with modifications.
Source: Charles Darwin’s Evidence for Evolution, by Dr. Niles Eldredge

B. Patterns based on observations of similarities among species:

.
C. Patterns based on observations regarding the distribution of organisms
.
.
The distribution of organisms provides evidence for evolution through patterns observed in geographic distribution, endemic species on islands, and changes in distribution seen in the fossil record.
Observations regarding the distribution of organisms provide valuable evidence for evolution. One such pattern is the geographic distribution of species. Similar environments often contain distinct yet closely related species. This can be observed in different regions around the world.
For example, the marsupials in Australia, such as kangaroos, koalas, and wombats, show remarkable similarities in their reproductive and developmental characteristics. These similarities suggest a common ancestry and adaptive radiation in response to the unique Australian environment.
Another significant observation is the presence of endemic species on islands. Islands provide isolated habitats, allowing for unique evolutionary processes to occur. The Galapagos Islands, famously studied by Darwin, exhibit an array of species found nowhere else on Earth.
The finches he observed there had different beak shapes and sizes, each adapted for specialized feeding habits. This diversification is thought to have occurred through natural selection acting on a common ancestor.
Furthermore, fossil records indicate that the distribution of organisms has changed over time. For instance, the discovery of similar fossils in South America and Africa suggests that these continents were once connected, supporting the theory of continental drift and explaining the presence of related species in both regions.

Classify each situation as a density dependent, inverse density dependent, or density independent mortality factor A forest fire kills 80% of the lodgepole pine trees found in a state park. As a heron population grows, competition for food and nesting sites survival A jaguar kills 4 antelope per week regardless of the size of the antelope herd. An unusual cold spell in April resutls in very high mortality for Florida manatees. Death rates from avian malaria decline as tropical bird species lose habitat.
Below is the Classification of each situation as a density dependent, inverse density dependent, or density independent mortality factor.
Density dependent - Competition for food and nesting grounds among more herons lowers the likelihood that their young will survive. As the habitat of tropical bird species is lost, avian malaria mortality rates decrease.
Inverse density dependent - No matter how many antelope there are in the herd, a jaguar only kills 4 of them each week.
Density independent - Eighty percent of the lodgepole pine trees in a state park perish in a forest fire. The mortality rate of Florida manatees is extremely high as a result of an unprecedented cold period in April.
Reasons:
Nesting and food competition are two density-dependent factors that have an impact on the first species' offsprings' ability to thrive.
For the second, the environment is a density-dependent component that changes as the number of tropical bird deaths from avian malaria declines.
A jaguar kills four antelope per week, regardless of the impact on the antelope population. Inverse density dependent. This component depends inversely on density.
Independent of density, a forest fire decimates 80% of the pine trees. The amount of trees or their density in the area has absolutely no bearing on how many trees per square mile perish in a forest fire. It is therefore a factor independent of density.

The extremely long tubular organ you discover during your fetal pig dissection that is associated with a dense network of vascular tissue is most likely the small intestine.
The small intestine is the longest segment of the gastrointestinal tract, which is the long, continuous pathway through which food travels in your digestive system. Food is broken down into liquid in the small intestine, where the majority of its nutrients are absorbed. The waste is then transferred to the large intestine.
A fetal pig dissection is useful for anatomy studies because the organs are easy to find and identify due to their size.
The small intestine is by far the longest section of the gastrointestinal tract, measuring approximately 22 feet in length. The lining of the small intestine has a large surface area that has been scrunched into folds and peaks. Many layers of tissues and muscles line the tube. Nerves, blood vessels, immune cells, and lymphatic glands are all found in the tissues.

What do you think is meant by the statement “the human digestive system is very efficient at squeezing everything it can out of any food?" How do you think this relates to the way biomolecules are broken down and used bythe body?
Answer: the digestive system is capable enough to absorb the nutrients out of food that we eat, which is the same with the other body parts in our body when we take in food.
Answer:
The statement means that the human digestive system can adapt to extreme diets in order to survive. For example, carbohydrates can be broken down into sugars and used for energy. But when carbohydrates are not available in the required amount, it can also break down fats to provide the body with the required amount of energy. This explains why Deb has enough energy to keep going, even on her extremely limited diet.

To write an inclusive hypothesis from investigation, it should be structured with Mechanism of Evolution, Hypothesis and Data.
How to hypothesize?Mechanism of Evolution
The mechanism of evolution that I think caused the increase in FQ resistance is natural selection. Natural selection is the process by which organisms that are better adapted to their environment are more likely to survive and reproduce. In this case, the bacteria that are resistant to FQ are more likely to survive and reproduce because they are not killed by the drug. This means that the population of bacteria will become more resistant to FQ over time.
Hypothesis
My hypothesis is that the increase in FQ resistance in the bacteria on the farm is due to natural selection. I believe that this is because the bacteria that are resistant to FQ are more likely to survive and reproduce, which means that the population of bacteria will become more resistant to FQ over time.
Data
The new data supports my hypothesis because it shows that the number of bacteria that are resistant to FQ has increased. The data also shows that the bacteria that are resistant to FQ are more likely to be found in the environment where the FQ is being used. This suggests that the bacteria are evolving to become resistant to the FQ.
How to Include the Data
You can include the data in your hypothesis by stating that the increase in FQ resistance is due to the fact that the bacteria that are resistant to FQ are more likely to survive and reproduce. You can also include the data by showing a graph of the number of bacteria that are resistant to FQ over time.
This is an example of how to include the data in the hypothesis:
