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.

A) Fern, puffball, grass
B) Pawpaw, fern, grass
C) Grass, blue-green algae, fern
D) Methanogen, blue-green algae, fern, grass
Answer:
B) Pawpaw, fern, grass
Explanation:
The pawpaw, fern, and grass are all part of the Plantae kingdom. They all share the same basic characteristics, and they all have a same distant ancestor. All three, even though they don't look alike a lot, are true plants, having well developed root systems, steams, and complex leaves through which they perform the process of photosynthesis. The ferns are the oldest of the three, having existed since the Carboniferous period, and they are plants that reproduce via spores. The pawpaw is part of the flowering plants, and these plants are much recent as they only occurred at the end of the Cretaceous period. The grass is the most recent of plants, occurring only around 25 million years ago, and it uses the nature to disperse its seeds and reproduce.
Answer:
The correct Answer is B. Pawpaw, fern, grass

Of the following elements, which is the MOST reactive?
A. F
B. Cl
C. Ar
D. Ne
We can exclude Argon (Ar) and Neon (Ne) they are both very stable. Chlorine (Cl) is reactive but not as much as Fluorine (F). So my answer would be A.
(A)
ExplanationReactivity is an elements ability to gain an electron. So the better it is at "stealing" electrons, the more reactive it will be. The thing that makes fluorine so reactive is its electronegativity. Therefore, since fluorine has a higher electronegatvity than chlorine, fluorine is more reactive.
When hydrogen and oxygen combine to create water the _______ are shared between the atoms in the newly formed compound
A) protons
B) neutrons
C) orbitals
D) valence electrons
Answer:
Valence electrons.
Explanation:
Electron, proton and neutron are the sub atomic particles of the atoms. The electrons revolve around the nucleus whereas the protons and neutron remains inside the nucleus.
The water contains hydrogen and oxygen. The electrons are shared between the hydrogen and oxygen to form the new compound water. The electrons participate in the formation of compound because they are present outside the nucleus.
Thus, the correct answer is option (D).
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.
Thus, The Natural selection that results from one sex's desire for particular traits in people of the other sex.

What is the relationship between temperature and the dissolution of ocean water salts?
Answer: Direct proportion. The salinity of water in the ocean rises with higher temperature because water is evaporated from the ocean, leaving more solutes (salts) in it.
i hope this helps you if it does please mark brain list i really need it to level up :)
A positive relationship is shared between the temperature and saltiness of the oceans waters. As density increases, the saltiness in oceans waters does too.
Saltiness descreases when polar caps melt or increases from the freezing of polar caps. Evaporation can increase saltiness and density too and in turn freshwater decreases saltiness and density.
(Sorry this is all I could find about relationships between the oceans waters and the dissolution in oceans water salts. (

As intense pressure is placed on the planet's limited resources, businesses are again turning to technological innovation. New and emerging technologies like those listed above should see human civilization through the 21st century and into the next with adequate supplies of __________ for people of all nations.
Answer:
technology
Explanation:
Technological innovation plays a crucial role in ensuring the sustainability of our planet's resources in the face of increasing demand and finite supplies. It is hoped that technology will allow the equitable distribution of essential resources such as food, water, and energy to sustain human civilization, yet a balance must be maintained, acknowledging the Earth's resource limits.
Addressing Resource Sustainability Through Technological Innovation
As human civilization progresses into the 21st century, there is a pivotal role that technological innovation plays in ensuring the sustainability of our planet's resources. Balancing the increasing pressures from population growth and the escalating demand for commodities, technology stands as both a beacon of hope and a field replete with challenges. Despite the socio-economic and environmental constraints, optimists believe that ongoing advancements in technology will bolster our capacity to maintain and distribute essential resources such as food, water, and energy to accommodate everyone across the globe. With the integration of sustainable practices and effective resource management, technology could indeed facilitate the fulfillment of human needs without depleting our natural assets.
However, this optimism is checked by voices cautioning against unfettered reliance on technology. Acknowledging that the Earth's resources are finite, it is imperative to consider the limitations of technology and recognize the need for a cultural shift towards sustainable living and reduced consumption, especially in affluent nations. As we continue to navigate the realities of the Anthropocene, a term that denotes the significant impact of humans on Earth's geology and ecosystems, it becomes evident that the alignment of technological development with sustainability principles holds the key to a viable future for all nationalities.

Prominences may be seen in the suns
Answer:
its Corona for Apex
Used the other answer and it wasn't it so here it is smh.
Explanation:
Prominences are indeed a common phenomenon observed in the Sun's atmosphere, specifically in the solar chromosphere and corona.
A prominence is a relatively cooler and denser structure composed of solar gases, primarily hydrogen and helium, that becomes visible as a bright, arch-like or loop-like feature extending from the Sun's surface. Location: Prominences are located above the Sun's visible surface, known as the photosphere, in the outer layers of the solar atmosphere. They are best observed during solar eclipses or through specialized solar telescopes equipped with filters to block out the intense brightness of the Sun's photosphere. Types of Prominences: There are two main types of solar prominences: quiescent prominences and eruptive prominences.
prominences are prominent features seen in the Sun's outer atmosphere, characterized by arch-like structures formed by cooler and denser solar gases. They are manifestations of the Sun's complex magnetic activity and provide valuable insights into solar behavior, contributing to our understanding of solar physics and space weather phenomena.

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.
4. d. Focus on other people.
It is easy to confuse this because Myers' has something similar on the list but d is the right answer.

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.

What is a gene?
A- a section of a protein that codes for DNA
B- the alternate version of a trait
C- the visible trait in the F1 generation
D- a section of DNA that codes for a specific trait
A gene is a section of DNA that codes for a specific trait or protein. It provides instructions for the production of a protein, determining an organism's traits. The correct answer to the original question is (D).
Explanation:A gene is a section of DNA that codes for a specific trait, so the correct answer to your question is (D). The primary function of a gene is to provide instructions for the production of a specific protein or a set of closely related proteins, which in turn determines an organism's traits. For instance, a gene in peas could be responsible for whether the peas are yellow or green. This DNA sequence is transcribed into mRNA, which is then translated into protein sequences. Thus, the gene (DNA) acts as the blueprint, guiding the cellular machinery to build proteins.
