The theory of plate tectonics is a relatively new idea, developed in the mid-20th century following the discovery of tectonic features on sea-floors. Can you imagine our explanation of faults, earthquakes, mountains, and rifting before the plate tectonic revolution?
Answer: Plate tectonics is the theory that Earth's outer shell is divided into several plates that glide over the mantle, the rocky inner layer above the core. The plates act like a hard and rigid shell compared to Earth's mantle.
Explanation:
Plates interact at three types of plate boundaries: divergent, convergent and transform. Most of the Earth's geologic activity takes place at plate boundaries.
Answer:
boom ka boon sorry cant ill try
Explanation:
Plate tectonics has revolutionized virtually every discipline of the Earth sciences since the late 1960s and early 1970s. It has served as a unifying model or paradigm for explaining geologic phenomena that were formerly considered in unrelated fashion. Plate tectonics describes seismic activity, volcanism, mountain building, and various other Earth processes in terms of the structure and mechanical behaviour of a small number of enormous rigid plates thought to constitute the outer part of the planet (i.e., the lithosphere). This all-encompassing theory grew out of observations and ideas about continental drift and seafloor spreading.
In 1912 the German meteorologist Alfred Wegener proposed that throughout most of geologic time there was only one continental mass, which he named Pangaea. At some time during the Mesozoic Era, Pangaea fragmented and the parts began to drift apart. Westward drift of the Americas opened the Atlantic Ocean, and the Indian block drifted across the Equator to join with Asia. In 1937 the South African Alexander Du Toit modified Wegener’s hypothesis by suggesting the existence of two primordial continents: Laurasia in the north and Gondwanaland in the south. Aside from the congruency of continental shelf margins across the Atlantic, proponents of continental drift have amassed impressive geologic evidence to support their views. Similarities in fossil terrestrial organisms in pre-Cretaceous (older than about 146 million years) strata of Africa and South America and in pre-Jurassic rocks (older than about 200 million years) of
Name and describe all the ways carbon enters the atmosphere.
Carbon enters the atmosphere through processes such as burning of fossil fuels, respiration, and decay of organic matter.
Explanation:Carbon enters the atmosphere through several processes:
Burning of Fossil Fuels: The combustion of fossil fuels such as coal, oil, and natural gas releases carbon dioxide into the atmosphere.Respiration: Both humans and animals release carbon dioxide into the atmosphere during the process of cellular respiration.Decay of Organic Matter: Decomposition of dead plants and animals releases carbon dioxide and methane, a potent greenhouse gas, into the atmosphere.These are just a few examples of how carbon enters the atmosphere. It is important to note that while carbon is a natural part of the Earth's carbon cycle, human activities have significantly increased the amount of carbon dioxide in the atmosphere, contributing to global climate change.

Which seasons are shown in model B for the Northern and Southern Hemispheres? Explain your answer.
Answer:
The Northern Hemisphere is pointing toward the Sun, so it is summer in the Northern Hemisphere. The Southern Hemisphere is pointed away from the Sun, so it is winter in the Southern Hemisphere.
Explanation:
The seasons in the Northern and Southern Hemispheres are determined by Earth's tilt. In June, it's summer in the Northern Hemisphere due to more direct sunlight and longer days, while it's winter in the Southern Hemisphere. This pattern is reversed in December. Spring and autumn represent more equal sunlight distribution. But, latitudinal location also affects the intensity of seasons.
Explanation:The seasons in the Northern and Southern Hemispheres are determined by the tilt of Earth's axis of rotation. In June, when the Northern Hemisphere 'leans into' the Sun, it is summer in the Northern Hemisphere due to longer days and more direct sunlight, whereas it is winter in the Southern Hemisphere. In December, this pattern is reversed: the Southern Hemisphere receives more direct sunlight and experiences summer, while it is winter in the Northern Hemisphere.
During the spring and autumn equinoxes, both hemispheres receive equal shares of sunlight. Specific dates like June 21 and December 21 represent the summer and winter solstices, respectively, and March 21 and September 21 represent the spring and autumn equinoxes. However, the effects of seasons vary at different latitudes. Near the equator, there's less variation in seasons, whereas in the polar regions, the differences are more pronounced.

8. What can be concluded from the evidence that coughs and sneezes are natural
reflexes and from the evidence that our immune system attacks allergens ?
D
9. What two possible reasons for the increase in allergies are explained in the passage?
Use evidence from the text to support your answer.
10. What can be concluded about the increase of allergies in the future? Use the
evidence from the text to support your answer.
Answer and explanation:
8. What can be concluded from the evidence that coughs and sneezes are natural reflexes and from the evidence that our immune system attacks allergens?
Coughing and sneezing are natural defense mechanisms that consist of the sudden expulsion of air from the respiratory tract, with the intention of expelling any substance harmful to the body.
Allergies are the product of an exaggerated response of the body to the presence of environmental substances, such as dust, fungi and pollen, called allergens. This abnormal response is caused by an immune system previously sensitized to these substances.
Under normal conditions, the immune system is designed to defend an individual against potentially harmful elements. Coughs and sneezes are natural defense mechanisms, which are exaggerated in allergy sufferers.
9. What two possible reasons for the increase in allergies are explained in the passage?
- "Some scientists think our immune systems don't have enough to do ..." "... when our immune system have fewer germs to fight, they can get confused".
According to the excerpt, an immune system that has been inactive due to less contact with germs, looks for a way to attack any substance foreign to the body, which would be a mechanism that promotes the presence of the allergic response.
The confusion of the immune system would be given in some people by reacting in an unusual way to environmental stimuli or food, which do not affect the majority of people.
- ... "weather is warmer for longer periods now, so plants bloom longer .. release pollen, which is a common allergen".
Plant pollen is considered an aeroallergen capable of producing the response with sneezing or coughing in sensitive people.
Other evidence implies an increase in the amount of aeroallergens, as a consequence of the temperature change. A warm temperature for long periods of time promotes flowering in plants more frequently, and there is more pollen dispersed in the environment.
10. What can be concluded about the increase of allergies in the future?
In the text it can be clearly seen how, according to statistical data, the presence of allergies in more people has increased over time.
Many factors may induce an increase in the number of allergic patients in the future, such as the example provided by the passage of children less exposed to germs due to the use of increasingly available medications.
In the past, there were fewer allergies because the immune system remained active to defend the body without the help of drugs.Additionally, the increase in processed food products may be a factor that in the future increases the appearance of allergies in the population. Again, the environmental factor plays a determining role. Over time, many climatic changes occur, which, combined with environmental pollution, may lead to increased allergies in the future.In the images below you will find the information of the article about allergies.
Coughs and sneezes are natural reflexes that help expel irritants while our immune system attacks allergens. The increase in allergies can be attributed to the hygiene hypothesis and genetics. Allergies are expected to continue increasing in the future.
Explanation:The evidence that coughs and sneezes are natural reflexes suggests that they are part of our body's defense mechanisms to expel irritants or pathogens. Similarly the evidence that our immune system attacks allergens indicates that it recognizes them as harmful substances and launches an immune response to protect the body. In the passage two possible reasons for the increase in allergies are explained. The first reason is the hygiene hypothesis which suggests that reduced exposure to pathogens in childhood may lead to an overactive immune response to harmless substances. The second reason is the role of genetics, as allergies can be inherited. Based on the evidence from the text, it can be concluded that allergies are likely to continue increasing in the future. The passage mentions the rise in prevalence and the need for more effective allergy treatments, indicating that the problem is expected to persist.

Why do dark-colored shirts get hotter in the sun than light-colored shirts!
Answer:
O A. Dark-colored shirts reflect less radiation.
Explanation:
Darker shirts absorb more heat then the light colored shirts because of the light energy. Dark colored shirts reflect little solar light and heat energy but get hotter in the end.
Due to the light energy, darker shirts absorb more heat than lighter shirts, hence option A is correct.
How do dark-colored shirts get hotter in the sun?Light-colored clothing reflects the majority of visible wavelengths, which reduces heat absorption. Contrarily, clothing that is darker or blacker absorbs more wavelengths and heat, making it warmer to wear.
On the day, you walk, dash to make it to the bus on time, go to lunch, and the shirt ends up soaking all the sunlight.
This light is transformed into different types of energy because it does not just vanish heat enters and is then released.
Therefore, because black clothing is a superb light absorber, it will thus produce more heat the darker it is, hence option A is correct.

Explain why it is advantageous for organisms such as fungi and algae to
form mutualistic relationships.
Answer:
Each organism benefits from the other, because each organism provides something the other cannot get on its own.
Explanation:
Fungi and algae form mutualistic relationships because they eat decomposing material and provide protections to other organisms.
Mutualistic relationships between fungi and algae are advantageous because each organism provides a benefit to the other; fungi get nutrients from algae, and algae get a safe environment from fungi. Both organisms can thus survive in environments they otherwise couldn't.
Explanation:It's advantageous for organisms such as fungi and algae to form mutualistic relationships because they each offer something beneficial to the other. In a mutualistic relationship, both organisms benefit. For instance, fungi get photosynthesized nutrients from algae. On the other hand, algae get a safe, moist environment where they can grow, which is provided by the fungi. Through a mutualistic relationship, both algae and fungi can survive in environments where they might not be able to live independently. This type of relationship is a prime example of mutualistic symbiosis at play in the natural world.

What anatomy is the study of similarities and differences in organisms structures
Answer:
Comparative anatomy.
Explanation:
Comparative anatomy is a branch of science in which we study about similarities and differences present in different organisms. This type of study is very important for the classification of living organisms. Comparative anatomy tells us about the evolution of an organism. Scientists study DNA, embronic structure and the internal structure of species to see the evolution of different organisms.
Final answer:
Comparative anatomy is a field of biology that investigates the structural similarities and differences among various species to deduce their evolutionary relationships, using homologous and analogous structures as evidence for common ancestry and evolution.
Explanation:
Comparative anatomy is the branch of biology that studies the similarities and differences in the structures of different species. Researchers examine the structures within various organisms to determine if their features are homologous, inherited from a common ancestor, or analogous, serving similar functions but not derived from a common ancestor. Such studies provide substantial evidence for the theory of evolution, revealing how closely related different organisms might be through their shared ancestral traits. These homologous structures, like the bone patterns in the limbs of mammals, suggest a common lineage, even if the limbs now serve different functions.
To clarify, the bones in the human arm, the wing of a bird, the fin of a whale, and the forelimb of a lizard, despite their different current uses, all originated from the same ancestral structure. Thus, comparative anatomy not only highlights the diversity of life but also underscores the underlying connections between species, offering insights into their evolutionary history.

It's unlikely for a child at that age to be forgetful of things like brushing their teeth or walking.
Explanation:
If a caregiver notices a preschooler losing previously acquired skills or a slowdown in development, it is crucial to consult with a pediatrician or child development specialist. This could indicate a developmental concern, which could potentially be addressed through early intervention.
Explanation:As a caregiver of a preschooler, if you notice that a child is losing skills they once had or if their development starts to slow down, you should not take this lightly. A range of skills and developmental milestones are associated with certain time frames, and failure to meet these can be an indicator of a potential issue. It is important to consult with a pediatrician or a child development specialist in such cases.
For instance, by the age of 2-3 years, a child starts showing signs of autonomy; they may choose their clothes, food, or toys. If you observe a reversal in such behaviour, it can signal some developmental concern.
Children also display cognitive abilities at certain ages, such as understanding object permanence or realizing certain facts about their environment. Reversal or stagnation in such cognitive abilities could be a cause for concern.
It is therefore important not to ignore such signs, but to communicate and address these through early intervention with specialized professionals. The goal is to promote healthy development and ensure the well-being of the child.
