Dr. Alex Young would like to know about your progress in solving the mystery about the rough-skinned newts. In the space below, answer the Chapter 1 Question: What caused this newt population to become more poisonous?
Use what you have learned so far to consider these claims:
Claim 1: Individual newts became more poisonous because they wanted to.
Claim 2: The newt population became more poisonous because of something in the environment.
Revised Claim 2: The newt population became more poisonous because the snakes in this environment caused poison to be an adaptive trait
Choose one or more claims to support with evidence and reasoning. You may also want to explain why one or more of the claims is definitely not correct.
Be sure to use some of the vocabulary words you have learned so far:
adaptive trait
distribution
environment
non-adaptive trait
population
trait
variation
Answer: whoaw guy this is a lot of work
1. The newt population became more poisonous because the snakes in this environment caused poison to be an adaptive trait.
The newts in this context, the more toxic in the new population, did not make the newts more poisonous because they can't control how poisonous their characteristics are. Since the new population has a high variation in the poisonous traits, when newts is introduced to snakes it will most likely be inexistent or less common, as the distribution of features shifts to high levels of poison, adaptive traits, low levels of poisons, non-adaptive traits, and medium levels of poison. This is important because when snakes enter the context of this new population, they become predatory to the newts and eat the newts, causing the distribution of features to become more frequent so that newts with adaptive features of more Poison can live longer and reproduce more, while newts with non-adaptive features of less poison become less prevalent and can not live much.
Explanation:
I tried to use the vocab
The newt population become more poisonous because the snakes in this environment caused poison to be an adaptive trait.
What do you mean by an Adaptive trait?An adaptive trait may be defined as a feature produced by DNA or the interaction of the epigenome with the environment. It facilitates the survival and reproduction of organisms in the environment.
The newt population refers to the toxic or poisonous compounds found in the environment. They are inherited from organisms, by nature, and other activities. But here, the newt population is derived from the adaptive trait of the snake which is poisonous. If the conditions get reversed, such that the variations lead to the non-adaptive trait being poisonous, it may not produce a newt population. The distribution of adaptive traits depends on the environment and the behavior of the population.
Therefore, the newt population becomes more poisonous because the snakes in this environment caused poison to be an adaptive trait.

Answer:
Alfred Russel Wallace was born in 1823 in Wales. He has been variously described as a naturalist, a geographer, and a social critic. He even chimed in on the debate over whether life could exist on Mars. His work on the theory of natural selection, however, is what he is best known for. During the second half of the nineteenth century, he became a public figure in England, known for his courageous views on scientific, social, and spiritualist subjects. His formulation of the theory of evolution by natural selection, which predated Charles Darwin's published contributions, is his most notable legacy, but it was only one of many contentious issues he studied and wrote about during his lifetime.
Relate the competitive exclusion principle to the concepts of niche, habitat, and competition
The competitive exclusion principle tells us that two species can't have exactly the same niche in a habitat and stably coexist. That's because species with identical niches also have identical needs, which means they would compete for precisely the same resources.
What factors contribute to deforestation in sub-saharn africa ? choose all that apply
people, logging, agriculture, recycled products, governmental protections
Deforestation is an complex problem. A recent study by the Food and Agriculture Organization (FAO) reported that during the decade from 1980 to 1990, the world's tropical forests were reduced by an average of 15.4 million hectares per year (0.8 percent annual rate of deforestation). The area of land cleared during the decade is equivalent to nearly three times the size of France. The phenomenon of deforestation is occurring globally, in different types of forests, and for different reasons.
At the end of 1990, Africa had an estimated 528 million hectares, or 30 percent of the world's tropical forests. In several Sub-Saharan African countries, the rate of deforestation exceeded the global annual average of 0.8 percent. While deforestation in other parts of the world is mainly caused by commercial logging or cattle ranching the leading causes in Africa are associated with human activity.
Developing countries rely heavily on wood fuel, the major energy source for cooking and heating. In Africa, the statistics are striking: an estimated 90 percent of the entire continent's population uses fuelwood for cooking, and in Sub-Saharan Africa, firewood and brush supply approximately 52 percent of all energy sources.
Land clearing by farmers may contribute as much as fuelwood gathering in the depletion of tree stocks. According to Porter and Brown, conversion of forests for subsistence and commercial agriculture may account for as much as 60 percent of world-wide deforestation.1 An estimated 20 to 25 percent of annual deforestation is thought to be due to commercial logging. The remaining 15 to 20 percent is attributed to other activities such as cattle ranching, cash crop plantations, and the construction of dams, roads, and mines. In Africa, governments invest substantially more in cash crops than in food crops as reflected in pricing and marketing policies. However, deforestation is primarily caused by the activities of the general population.
Proposed Solutions
While there is general agreement that deforestation is a problem, there is no consensus on its cause or on ways to develop a solution. Some of the proposed solutions include regulating the logging industry, developing forest protection schemes, and addressing human activities that promote deforestation.
Regulating the Logging Industry
Concerned mainly with commercial logging, this approach proposes the regulation of the worldwide industry in logging and other commercial uses of forests. For example, a global treaty on forestry could ban the cutting down of certain types of "endangered" trees (similar to the ban on ivory trade), or greatly decrease the harvesting of some trees (as was done with whaling), or agree to reduce deforestation by a certain percent each year. Regulating commercial logging can lead to sustainable management of forests. As such, countries can require a certain amount of tree replanting or creating tree plantations. Since much of logging is for the pulp and paper industry, that sector can be required to engage in more recycling of used paper products, rather than destroying more forests.
Commercial logging only accounts for at most one-quarter of the global deforestation problem, so focusing only on the logging industry is an inadequate solution. If a treaty on forestry is signed, it may have the unfortunate consequence of appearing to have resolved the problem without dealing with its underlying causes. This approach must be used in combination with others to treat this issue.
Forest Protection Schemes
This approach usually involves the creation of national parks or forest reserves. In developing countries, this may evolve out of pressure by the citizens and local environmental organizations, but the impetus usually comes from abroad. For example, donor countries and international NGOs may use "debt-for-nature" swaps to influence developing nations to set aside forest areas. The donor agencies effectively "buy" the forest area by paying off some of the target country's foreign debt in exchange for the promise not to develop the area. Such a deal has been successfully brokered between Norway and Costa Rica.
While trade regulations and protection of forests are frequently cited as solutions to the problem of deforestation, they are not enough. A recent review of various approaches towards regulating commercial logging concluded that by 1990 "there was general agreement that none of the approaches previously tried had been effective in slowing the rate of deforestation in tropical forests."2 Particularly for sub-Saharan Africa, these proposals do not address the underlying causes because fuelwood is the main source of energy in Africa, and most land clearing is for subsistence agriculture.

how do waves cause erosion? Explain in your own words and you will get brainliest
It causes erosion because the water particles are moving over a substance, which pulls away microscopic (and sometimes large) particles of that same substance. When a wave crashes into land or any substance, the particles on the outside of that same substance become loose, and in turn the wave takes the particles away from it and goes wherever the water goes.

Nuclear power is a nonrenewable energy resource. It is used to provide 20 percent of the electricity in the United States. How is nuclear energy harnessed to produce electricity, and what are two limitations of securing uranium?
Answer:
A nuclear reactor converts into electricity the heat produced by the fission of uranium nuclei. This electricity production can be adjusted according to demand. During normal operation, nuclear reactors are quite environmentally friendly, particularly with regard to greenhouse gases. Since the 1950s, reactors have evolved into “generations”, learning from the rare accidents to enhance their safety and robustness. Radioactive waste is produced in limited volumes, which allows for its containment in the very long term, but its management remains controversial.
