Answer:
A new species of hawk that preys on rabbits is introduced to the habitatThe hawks have more success in catching rabbits with white fur because they are easier to see in the habitatThe rabbits´ white fur mutate so their fur is tan or brownThe next generation of rabbits has a higher proportion of individuals with tan and brown fur.Explanation:
Natural selection is an evolutive force that can act favoring an allele or against it, according to how it affects the fitness of individuals. Natural selection selects beneficial alleles and increases their frequency in the population.
When many organisms in a population sharing the same trait die, it is because they did not have good fitness, so they were not adapted to the environment and its pressures. The alleles coding for that trait were not good for the fitness of the animals, so they do not get to survive.
These individuals die before reproducing, so they could not transfer their genetic charge to the following generation. Eventually, the alleles coding for the trait will decrease in the population, probably near zero. Natural selection is acting against this phenotype. Other alleles will be beneficiated, and their frequency in the population will increase.
This change in alleles frequency is what we call adaptation.
Natural selection results in adaptation, which means the increase of the aptitude phenotype. Aptitude is the contribution of each genotype to the next generation.
In many cases, adaptations can be correlated to environmental factors or selective pressures applied by other organisms or habitats.
Let us remember that a mutation is a change or alteration in DNI sequences that introduce new variants. Many of these are eliminated, but some of them might succeed and be incorporated into each individual. These mutations are the ones that have been selected by natural selection.
So, in the exposed example, we are focussing on rabbits populations.
• The selective pressure or modeling environmental factor is predation by the introduced hawk.
• The rabbits´ response to predation is the survival of only those that carry mutations ⇒ tan or brown fur
• Natural selection benefits these mutations.
• Tan or brown rabbits survive and increase their fitness.

Answer:
❑How much do you depend on natural ecosystems that you use for recreation (camping, fishing, hunting, hiking, swimming, boating)? 4
❑How much do you depend on natural ecosystems for the food you eat? 5
❑How important is preserving natural ecosystems to you? 5
❑How willing are you to sacrifice things in your life to make sure that natural ecosystems stay unharmed in the future? 4
Explanation:
The questions are closely related to ecosystemic services and how humans make use of it. Let us first review theoretical concepts, and then discuss the rating of the questions.
Ecosystem services refer to all the benefits that human beings can get from ecosystems, not only for survival but also for good life quality. There are four types of ecosystem services:
• Provision or supply:
These are the products obtained by nature to be used or consumed, directly or with previous processing. Among them, we might mention food, clear freshwater, fertile soils, geotic materials, raw materials (used for clothing, construction), renewable fuels, biochemical compounds, pharmacological/medicinal resources, among others.
• Regulation:
Refers to ecological processes that improve life. Among others, we might mention climate regulation, CO² absorption, water purification, air purification, erosion control, natural disaster avoidance such as flooding, soil fertility maintenance, waste recycling, pest/plague control, etc.
• Cultural:
Refers to not the material benefits. Ecosystems also provide a recreational place or area to spend time, learn, enjoy spiritual/religious space, and are a source of inspiration. It is considered to be cultural patrimony and the source of scientific knowledge.

I answered the questions from my personal point of view, and considering 5 as the most important topic, and 1 as the less important. So, from most important to less important is 5, 4, 3, 2, 1.
❑How much do you depend on natural ecosystems that you use for recreation (camping, fishing, hunting, hiking, swimming, boating)?
Probably, we as species, do not need these activities to survive. However, we need them to have good mental health. These are activities that we enjoy and that produce satisfaction. Whenever we do things that we enjoy our organism secretes hormones that make us feel happy. This feeling is important when people are stress about any personal situation. So, this question does not get the highest rate, but it gets a significant one, a 4.
❑How much do you depend on natural ecosystems for the food you eat?
Basically, we depend on nature and the ecosystem to get food and any kind of supply. If the ecosystems are damaged and altered, there is a general disbalance, and every form of life is affected. Some species might even get extinct. If we keep damaging the environment as we are doing currently, we will get to the point of not having any supply available to survive. So this is one of the most important questions, which gets the highest rate, a big 5.
❑How important is preserving natural ecosystems to you?
This question is closely related to the anterior one. It is very important for us as a species to realize that we depend on nature 100%, that we need to take care of it and preserve ecosystems all around the world. With no healthy and equilibrated ecosystems, we do not get to survive. So this is the other question that gets the highest rate, 5.
❑How willing are you to sacrifice things in your life to make sure that natural ecosystems stay unharmed in the future?
This one is kind of difficult to answer, We could say that we are 100% willing to sacrifice to make sure ecosystems stay unharmed. However, we are so used to consumption, technology, confort, an easy lifestyle, and etc, that would be really difficult for us to sacrifice everything that we are used to. Just imagine yourself giving up your cellphone or your computer. Technology is one of the most polluting industries in the world. But we depend so much on it, that seems almost impossible to imagine us without it. This is why my score for this question is a 4. Personally, I surely would sacrifice too many useful things, but I find it hard to sacrifice some others.

1 poi A student draws a diagram of a plant cell. The diagram is 40mm in width. The plant cell is 0.02mm in width. What is the magnification of the student's drawing? A. 0.005 B. 0.08 C. x200 D. x2000
Answer:
D. x2000
Explanation:
magnification = image(drawing size)/actual size
magnification = 40/0.02
magnification = x2000
The magnification of the diagram is x2000. So, the correct option is (D).
What is Magnification?Magnification is the process of magnifying something. It enlarge the apparent size and not the physical size. This type of enlargement is certainly quantifiable. It also refers to the action of visually enlarging an object with the help of lenses.
This concept exist in two forms-
1. By microscope
It makes small objects appear large
2. By telescope
It makes a distant object which appear closer and the images are more clear and defined.
The formula of magnification represents the ratio of the height of the image to the ratio of the height of the object.
Magnification = image/actual size
For given example, magnification = 40/0.02
magnification = x2000
Thus, the magnification of the diagram is x2000. So, the correct option is (D).

Under which circumstance will a disease not spread beyond a few individuals in a population? If the rate of infection is lower than the rate of recovery, the reproductive ratio of the infection will be less than 1. If the rate of recovery is lower than the rate of infection, the reproductive ratio will be greater than 1. If the primary case infects a large number of people very quickly, the reproductive ratio will be less than 1. If the reproductive ratio is greater than 1, only a few individuals in a population will be infected.
Answer:
The correct answer is - If the rate of infection is lower than the rate of recovery, the reproductive ration of the infection will be less than 1.
Explanation:
The rate of infection is the chances or occurence of new cases of infection in a particular population over a particular time period and the rate of recovery is the occurence of the recovery of an individual case over a period of time. These two rates determines if a disease or infection is spreading faster or lesser.
The higher the rate of infection to rate of recovery it is more lkely to be spreading rapidally and higher the rate of recovery the infection not spreading beyond few individuals in the population. In the later case, the reproductive ration of the infection will be less than 1.
Scientists have noted patterns in the Earth's seafloor structures. For example, volcanic ridges are typically located in the center of the oceans, and trenches are typically located along the edges of continents. In addition, seafloor rocks found at the trenches are usually older than seafloor rocks found at the volcanic ridges. Which explanation of the past movement of the Earth's plates is best supported by this information? A. The continents were pushed apart when new crust formed in the center of the ocean and pushed older crust away from the volcanic ridges. B. The continents were separated when new crust that formed at the edges of the continents pushed older crust towards the center of the ocean. C. The formation of new crust at the trenches widened the seafloor and pushed the edges of the continents away from one another. D. The Earth's crust formed at the trenches and moved towards the volcanic ridges to make room for newer crust, pushing the continents apart.
Answer:
A. The continents were pushed apart when new crust formed in the center of the ocean and pushed older crust away from the volcanic ridges.
Explanation:
The crust is divided into many plates that move over the mantle. Nowadays, there are six different bigger plates and twelve that are smaller. These plates are limited by three types of ridges or borders that differ in the movement they produce.
Boundaries types:
I. Divergent
II. Convergent
III. Transforming
In divergent boundaries, a new crust is created by the rising molten materials coming from the mantle. Two plates separate, and the stream of hot material creates a new seabed between them. It occurs an expansion of the sea bottom. As old plates get separated, the new and young crust instantaneously gets formed. The emerging mantle occupies the space left by the separation of the two plates. This process occurs along with an underwater mountain range, known as the mid-oceanic ridge or divergent ridge. An example of this is the ridge located in the middle of the Atlantic Ocean, extending from Greenlander to the southernmost point of South America.

Dominic made the table below to organize his notes about mixtures. A 1-column table. The first column labeled properties of mixtures has entries has no set composition, must have more than one state of matter, must have more than one substance. What mistake did Dominic make? The title should read “Properties of Solutions” because some mixtures do not have all of the properties listed. There is a definite recipe to make each mixture, so the composition of a mixture is set. Although it is possible to have more than one state, it is also possible to have only one state. A single substance can be used to make a mixture if the substance is composed of more than one element.

How can a scientist determine if two species are obligate mutualists? The scientist should observe the species in the environment to determine the types of interactions that the two species have. Then, the scientist should transplant each species alone to a new area and simultaneously transplant both species together to see if the single-species transplants die. The scientist should observe the species in the environment, determine the types of interactions that the two species have, and then add an invading species to see if it outperforms one of the other species. The scientist should observe the species in the environment, determine the types of interactions that the two species have, and then transplant both species to a new location to observe if they do better or worse than the individuals in their old location. The scientist should observe the species in the environment, determine the types of interactions that the two species have, and then remove one of the species to see if the other species does not survive.
Answer:
The scientist should observe the species in the environment to determine the types of interactions that the two species have. Then, the scientist should transplant each species alone to a new area and simultaneously transplant both species together to see if the single-species transplants die
Explanation:
When two species are obligate mutualists, both species benefit one another in such a way that one cannot survive without the other. Hence, in order to find out if two species are indeed obligate mutualists, they should be transplanted together away from other species on one side, and also transplanted individually on another side.
If they are obligate mutualists, the individual transplant would find it difficult to survive and should die in no time while the transplant done together should survive. All other factors being kept constant.
