Answer:
Hi,
The correct answer is option (C) Overhunting led to the extinction of large herbivores species
Explanation:
Herbivores are those animal species that eat plants only.Hunters and gatherers depended on their hunting skills to obtain meat as a source of protein/food for their families.Most of the animals that were hunted were herbivores.Overhunting reduced the number of these species because the process was not controlled thus there was no time for the animals to increase in numbers in the natural process

_______ is the process where plastic-eating fungi are sent to landfills
Answer:
Bioremediation
Biological augmentation
Biodiversity expansion
Pollution cleanup
Explanation:
Biological augmentation is the method where plastics eating fungus are sent to landfills.
The process of sending plastic-eating fungi to landfills represents a solution to manage plastic waste, a significant environmental challenge. Fungi, especially saprobes, are known for their ability to decompose organic matter and certain synthetic materials. This bioremediation technique, if successful, could help in reducing persistent plastic waste.
Explanation:The process where plastic-eating fungi are sent to landfills represents an ecological strategy to address our growing plastic waste problem. Fungi, most of which are saprobes, play a crucial role in the decomposition process, breaking down organic matter and in some cases, synthetic materials like plastic.
Plastic waste, much of which is single-use, is a significant environmental issue due to its persistence in our ecosystems, particularly in landfills where a single plastic bottle can take up to 450 years to decompose. With a staggering daily disposal rate of 50 million bottles in the U.S. alone, the plastic problem is intensifying.
Fungi primarily derive their nutrients from decaying organic matter, often breaking down compounds such as cellulose and lignin into absorbable glucose molecules. This ability has led to this decomposer's potential use in bioremediation, where organisms are used to help reduce pollution and waste. Considering their propensity for decomposition, certain fungi species that can eat plastic are being developed and investigated, which if successful, could provide a sustainable way to reduce the problematic buildup of plastic in our landfills.

If only 10% of the energy from one trophic level passes up to the next level, what happens to the 90% energy that is not passed on?
Answer:
It is lost as heat.
Explanation:
As energy is transferred from one trophic level to the next, energy involved in metabolic processing(breaking of chemical bonds) is converted into heat energy.
Energy from metabolic activity, or the breakdown of chemical bonds, is transformed into heat energy when it is passed from one trophic level to the next.
What is the ten percent law?
A linear relationship is created when an organism depends on another for its nutritional needs and that other organism depends on another. Raymond Lindemann presented the 10% law of energy transmission in a food chain.
According to the 10% law of energy transfer, this occurs whenever energy is moved from one trophic level to another. There is a significant reduction in energy until it reaches the topmost trophic level since only 10% of energy transfers to the next trophic level and 10% of that energy level goes to the next energy.
The food chain has a total of four trophic levels. Grass makes for the first trophic level and is present at the producer level. It gets solar energy, utilizes the majority of it to prepare food, and only uses a little percentage of it. Rabbits are at the fourth trophic level and constitute the seemed trophic level, receiving 10% of their energy from them.
Therefore, the rest of the energy is lost in the form of heat.

How does the circulatory system interact with the muscular system
The circulatory system provides oxygen and nutrients to the muscles and removes waste products. During exercise, the circulatory system increases blood flow to the working muscles.
Explanation:The circulatory system interacts with the muscular system by providing the necessary blood supply to deliver oxygen and nutrients to the muscles, while also removing waste products such as carbon dioxide. The heart, which is part of the circulatory system, pumps oxygenated blood to the muscles through the arteries. The blood vessels in the muscular system, known as capillaries, then facilitate the exchange of oxygen and nutrients with the muscle cells.
The interaction between the circulatory and muscular systems is crucial during exercise. When muscles contract during physical activity, they require more oxygen and nutrients. The circulatory system responds by increasing the heart rate and dilating blood vessels to deliver a higher volume of blood to the working muscles. This increased blood flow helps to maintain muscle function and prevent fatigue.

which of the following is NOT one of myers’s 10 suggestions for a Happy Life ?
Answer:
this is the suggestions for a happy life by Myer's because you didn't give anything.
Explanation:
Want a Happier Life?
Realize that enduring happiness doesn't come from success. People adapt to changing circumstances—even to wealth or a disability. Thus, wealth is like health: its utter absence breeds misery, but having it (or any circumstance we long for) doesn't guarantee happiness.
Take control of your time. Happy people feel in control of their lives. To master your use of time, set goals and break them into daily aims. Although we often overestimate how much we will accomplish in any given day (leaving us frustrated), we generally underestimate how much we can accomplish in a year, given just a little progress every day.
Act happy. We can sometimes act ourselves into a happier frame of mind. Manipulated into a smiling expression, people feel better; when they scowl, the whole world seems to scowl back. So put on a happy face. Talk as if you feel positive self-esteem, are optimistic, and are outgoing. Going through the motions can trigger the emotions.
Seek work and leisure that engages your skills. Happy people often are in a zone called "flow"—absorbed in tasks that challenge but don't overwhelm them. The most expensive forms of leisure (sitting on a yacht) often provide less flow experience than gardening, socializing, or craft work.
Join the "movement" movement. An avalanche of research reveals that aerobic exercise can relieve mild depression and anxiety as it promotes health and energy. Sound minds reside in sound bodies. Off your duffs, couch potatoes.
Give your body the sleep it wants. Happy people live active vigorous lives yet reserve time for renewing sleep and solitude. Many people suffer from a sleep debt, with resulting fatigue, diminished alertness, and gloomy moods.
Give priority to close relationships. Intimate friendships with those who care deeply about you can help you weather difficult times. Confiding is good for soul and body. Resolve to nurture your closest relationship by not taking your loved ones for granted, by displaying to them the sort of kindness you display to others, by affirming them, by playing together and sharing together. To rejuvenate your affections, resolve in such ways to act lovingly.
Focus beyond the self. Reach out to those in need. Happiness increases helpfulness (those who feel good do good). But doing good also makes one feel good.
Keep a gratitude journal. Those who pause each day to reflect on some positive aspect of their lives (their health, friends, family, freedom, education, senses, natural surroundings, and so on) experience heightened well-being.
Nurture your spiritual self. For many people, faith provides a support community, a reason to focus beyond self, and a sense of purpose and hope. Study after study finds that actively religious people are happier and that they cope better with crises.
Intro to Psychology final.

Female guppies tend to choose brightly colored mates. Over time, the population of guppies becomes more colorful. This is an example of…
Sexual Selection. Meaning: natural selection arising through preference by one sex for certain characteristics in individuals of the other sex.
The Natural selection that results from one sex's desire for particular traits in people of the other sex.
Thus, Members of one biological sex choose partners from the other sex to mate with (intersexual selection) and compete with other members of their own sex for access to partners from the other sex (intrasexual selection) in this form of natural selection.
Because of these two types of selection, some people in a population are more likely to successfully reproduce than others, for example because they are more attractive or choose to have children with attractive partners.
Frequent mating and having exclusive access to one or more reproductive females are advantageous to successful males.

Scientists use meteorites that hit Earth to provide evidence of the composition of Earth’s interior because they hypothesize that _____.
meteorites are made of the same material as peridotite and lava
meteorites have the same P and S wave speeds as rock samples
meteorites are made of the original material from which Earth formed
meteorites contain a smaller percentage of iron than Earth’s crust
Answer:
meteorites are made of the original material from which Earth formed
Explanation:
Meteorite is a fragment that passes through the earth's atmosphere and strikes the earth.
It is a metallic or stony body which is able to enter the earth.
Meteorites are widely believed to have formed with the earth when the solar system and other planets formed. They contain records of the earth's original composition. This is the main reason why they are suitable for radioactive dating. Example is the Stony Antarctica meteorites. Some of these meteorites have preserved their original composition.
Meteorites can be classified as stony, iron and stony-iron.
Some special set of meteorites contains lumps of materials that are thought to have formed first. These lumps are called chondrules. Meteorites with chondrules are called chondrites. These chondrules are rich in radioactive minerals and are very suitable for dating the earth.
Some meteorites also contain some black carbon matter that has been analysed to be amino acid. This has been very useful in understanding how life formed on earth. It provides an exotic origin of life on earth. These types of meteorites are called carbonaceous meteorites.
A good meteorite for dating would be one that is still very intact and has not weathered. Weathering affects the effectiveness of using earth materials for dating.
Meteorites provide evidence of Earth's interior composition because they are made of materials from which Earth originally formed, offering insights into the solar system's history and Earth's early building blocks.
Explanation:Scientists use meteorites that hit Earth to provide evidence of the composition of Earth’s interior because they hypothesize that meteorites are made of the original material from which Earth formed. Meteorites offer a glimpse into the early history of the solar system and are composed of primitive materials that have not been altered by heat or pressure since their formation. These celestial objects are believed to be remnants from the solar system's formation process, providing crucial information about the materials that constituted early Earth before it underwent differentiation and chemical processing. The study of meteorites helps scientists to understand the building blocks of Earth by offering a comparison with Earth’s interior composition, particularly the mantle and core.

An electromagnet is different from a permanent magnet because a electromagnet _____.
A: is magnetic
B: can push and pull
C: can attract some metals
D: can turn on and off
A permanent magnet is permanent while an electromagnetic acts as a magnet when electric current passes through.
It’s a temporary magnet but yes, it can be magnetic
It can be reversed due to which way the current is moving
This means when there isn’t a current it can turn off causing it to turn on and off depending on the current
The answer is D
Hope this helps! :3
Considering the definition of electromagnet and permanent magnet, the correct answer is option D: An electromagnet is different from a permanent magnet because a electromagnet can turn on and off.
An electromagnet is magnetized by the magnetic field generated by an electric current in a coil of wire. The more current flows through the coil, that is, the stronger the magnetic force of the electromagnet.
A permanent magnet is an object capable of maintaining the state of magnetization for a long period of time. Unlike an electromagnet, a permanent magnet can remain in an active state without external support.
So, an electromagnet is nothing more than a magnet whose magnetic field is produced by the passage of electric current. Its behavior is very similar to that of a permanent magnet, with the difference that its intensity can be controlled, increased and decreased, changing the intensity of the electric current that circulates. When the current is finished circulating, when it is disconnected, the magnetism disappears.
For its part, the permanent magnet does not depend on electric current for its operation and to provide its magnetism. The permanent magnet is, as the name implies, permanent, so it is permanently magnetic.
In summary, the correct answer is option D: An electromagnet is different from a permanent magnet because a electromagnet can turn on and off.
