What is the definition of subduction?

Answers

Answer 1

Answer:

Subduction is the sideways and downward movement of the edge of a plate of the earth's crust into the mantle beneath another plate.

Answer 2

Final answer:

Subduction is the process where a tectonic plate is forced beneath another at a convergent plate boundary, leading to the formation of subduction zones marked by high seismic and volcanic activity.

Explanation:

Subduction is a geological process that occurs at convergent plate boundaries, where one tectonic plate descends beneath another into the Earth's mantle. The descending plate moves in a sideways and downward direction, a phenomenon often associated with regions called subduction zones. Such areas are marked by features like ocean trenches, with the deep Japan trench being a notable example.

During subduction, the oceanic plate—which is typically thinner than the continental plate—is thrust down into the upper mantle. Here, under conditions of high pressure and temperature, the material of the subducted plate eventually melts. This leads to the recycling of crustal material through convection currents, balancing the crust formed at rift zones, where tectonic plates move apart. Earthquakes and volcanic activity commonly occur in subduction zones, revealing insights about the angle and nature of subduction beneath the Earth's surface.

Macromolecules are made of subunits called monomers. What are the monomers of protein called?

Answers

Answer: Amino acid

Explanation: proteins are made up of amino acids or we can also say that amino acids are the building block of proteins molecules. Amino acids are the basic subunit of the protein. Different Amino Acid joins and forms large molecules called polymers of protein.

The monomers of proteins are called amino acids, each consisting of an amino group, a carboxyl group, and a side chain.

Amino acids are organic compounds made up of four key components: an amino group (-NH2), a carboxyl group (-COOH), a hydrogen atom, and a side chain or R-group, which is unique to each amino acid.

The amino and carboxyl groups are crucial functional groups that define an amino acid's chemical properties and behavior.

There are 20 standard amino acids that serve as the building blocks for protein synthesis.

The variations in the R-group give each amino acid its distinct characteristics, including size, shape, charge, and chemical properties.

Amino acids link together through peptide bonds, forming linear chains called polypeptides.

When a peptide bond forms, a molecule of water is released in a condensation reaction. This repetitive bonding pattern forms the primary structure of a protein.

The sequence of amino acids in a protein chain is determined by the genetic information encoded in DNA.

Proteins exhibit a hierarchical structure, including primary, secondary, tertiary, and quaternary structures, which result from the interactions and folding of the polypeptide chains.

The specific sequence and arrangement of amino acids dictate a protein's final three-dimensional shape and function.

D. Brings blood from the heart to the liver

Answers

Answer:

Explanation:

C.

Final answer:

The pulmonary vein carries oxygenated blood from the lungs back to the heart. It is part of the pulmonary circulation that includes the heart and lungs, ensuring the blood becomes oxygenated before being pumped to the rest of the body.

Explanation:

The pulmonary vein performs a vital function in the human body's circulatory system. Specifically, option C is correct: it brings oxygenated blood from the lungs to the heart. Unlike other veins, the pulmonary veins are unique in that they carry oxygen-rich blood. The pathway of blood through the heart and to the body is critical to understand, especially when considering the pulmonary and systemic circuits. The pulmonary circulation is a section of the circulatory system which solely involves the heart and lungs. The right ventricle of the heart pumps deoxygenated blood into the right and left pulmonary arteries, which then transport this blood to the lungs where it becomes oxygenated. The oxygen-rich blood returns to the heart via the pulmonary veins, specifically the right and left pulmonary veins, which enter the left atrium of the heart.

The correct order of how blood flows from the heart out to the body and back again follows this sequence: The blood exits the heart through the aorta, travels through arteries, moves into capillaries, progresses through venules, and returns via veins.

The process of creating a current in a circuit by changeing a magnetic field

Answers

Answer:

The process of creating a current in a circuit by changing a magnetic field - electromagnetic induction.

Explanation:

The electromagnetic induction discovered by Michael Faraday, is a process that generates current or voltage in a conductor by placing the conductor in a changing magnetic field.

Here, the magnetic lines of force are applying a force on the free electrons in the conductor and causing them to move. The conductor must be perpendicular to the magnetic lines of force in order to produce the maximum force on the free electrons. There is no physical connection between the conductor and the magnet and the current is said to be induced in the conductor by the magnetic field.

The direction of the induced current is determined by the direction of the magnetic lines of force and by the direction the conductor is moving in the field. The applications of electromagnetic induction include inductors, transformers, electric motors, and generators.

Final answer:

Electromagnetic induction is the process where a changing magnetic field induces a current in a conducting path, such as a wire, described by Faraday's law. Essential in many technologies, it enables the functioning of generators, transformers, and various electronic devices.

Explanation:

Electromagnetic Induction

The process of creating a current in a circuit by changing a magnetic field is known as electromagnetic induction. This phenomenon occurs when a conducting path, such as a wire, is present in a changing magnetic field, leading to the generation of an induced current. The foundational principle behind this is Faraday's law of induction, which indicates that a change in magnetic flux through a circuit produces an electromotive force (EMF), hence inducing a current.

Electromagnetic induction is the basis for many technologies we use every day. For example, it is the operating principle behind electric generators, which convert mechanical energy into electric energy. Moreover, devices like transformers, used to step up or step down voltage levels, and various consumer electronics, like credit card readers and electric guitars, rely on this principle.

Overall, electromagnetic induction is pivotal to the functionality of electrical machines and the behavior of AC circuits. It is integral not only in power generation but also in various applications such as sensing, signal processing, and energy transfer.

As a result there is an uncontrolled cell division and an evolutionary process of these cells through natural selection within the organism. Rapid and uncontrolled reproduction of cells can produce benign tumors and some types of these tumors can become malignant, which is what is known as cancer. Benign tumors do not spread to distant parts of the body or invade other tissues, and usually do not pose a threat to life unless they compress vital structures or have some physiological activity (for example, that they are capable of producing a hormone) . Malignant tumors are able to invade other organs, spread to distant places (a process known as metastasis) and become a threat to life.

Final answer:

Parasitism is a symbiotic relationship where the parasite benefits at the expense of the host. Mutualism is a symbiotic relationship where both organisms benefit. Commensalism is a symbiotic relationship where one organism benefits, and the other is neither harmed nor benefited.

Explanation:

In biology, parasitism, mutualism, and commensalism are three types of symbiotic relationships that describe interactions between two organisms where at least one organism benefits.

Parasitism (+/- interaction): This refers to a relationship in which one organism, the parasite, benefits while the other, the host, is harmed. An example of this is a tapeworm living in a human's intestines. Mutualism (+/+ interaction): This is a symbiotic relationship in which both species benefit. An example of this is humans and gut bacteria, where bacteria digest food and produce vitamins that humans can't, and in return, the bacteria get a safe and nutrient-rich environment. Commensalism (+/0 interaction): This means one organism benefits while the other is neither harmed nor benefited.

Which of the following chemical structures can form hydrogen bonds with water? Methane (CH4), molecular oxygen (O2), hydrogen sulfide. explain

Answers

Answer: Molecular Oxygen (O2) and Hydrogen Sulfide.

Explanation:

A hydrogen bond is defined as the electrostatic attraction between an electrically negative atom and a hydrogen atom attached by a covalent bond to another electronegative atom. This bond is strong due to the number of atoms that bind, but weaker than a covalent bond or an ionic bond.

The atoms with the most significant negative electrical force are oxygen, fluorine, and nitrogen.

An example of a chemical structure formed by a hydrogen bond is water. The water is formed by two hydrogen atoms and one oxygen atom. Due to the majority of hydrogen atoms present in the water structure, it is possible to join other molecular structures such as fluorine.

I hope this information can help you.

Final answer:

Hydrogen sulfide can potentially form weak hydrogen bonds with water due to the presence of hydrogen atoms bonded to an electronegative sulfur atom, whereas methane and molecular oxygen cannot participate in hydrogen bonding with water.

Explanation:

A hydrogen bond is a type of intermolecular force that occurs when a hydrogen atom, covalently attached to a highly electronegative atom such as nitrogen (N) or oxygen (O), is attracted to a lone pair of electrons on another electronegative atom in a neighboring molecule. Among the substances listed (methane (CH4), molecular oxygen (O2), and hydrogen sulfide), hydrogen sulfide has the potential to form hydrogen bonds with water because it contains hydrogen atoms directly bonded to an electronegative sulfur atom. Methane, on the other hand, consists of hydrogen atoms bonded to carbon, which is not sufficiently electronegative to create hydrogen bonds. Molecular oxygen does not have hydrogen atoms and thus cannot participate in hydrogen bonding as a hydrogen bond donor. However, it is important to note that hydrogen sulfide's hydrogen bonding is much weaker compared to that of water due to the lower electronegativity of sulfur compared to oxygen. This affects the degree to which hydrogen sulfide can form hydrogen bonds with water.

Bill the explorer was hiking through the Brazilian rainforest when he came upon a strange, new organism which had yet to be classified. It was small, with a mass of only 10 grams. Bill noticed the organism was covered in feathers. After further investigation, Bill discovered that although it did not fly, it had hollow bones. How should Bill best classify this organism?

Answers

Answer:

Bill should classify the organism as a bird.

Explanation:

It would be right for Bill to classify the newly discovered organism as a bird. This is because the birds are a category of animals which have feathers as well as hollow bones. As for the flying criteria, not all birds belonging to this category can fly. For example, ostrich and kiwi cannot fly but yet still belong to the category of birds, Hence, this newly found organism can be classified into birds as it has feathers and hollow bones.

List 4 things humans and primates have in common.

Answers

Answer:

A. Opposable thumbs

B. Depth perception

C. Maternal care

D. Large brains

Explanation:

Opposable thumbs --> Primates have opposable thumbs and refined hand and foot development . An opposable thumb is able to be moved opposite the fingers of the same hand in order to better grasp objects. This is an adaption for an arboreal, or tree-dwelling, lifestyle because it helps the primates have strong grips on the branches.  Raccoons, dogs, and other non-primate mammals do not have opposable thumbs. This means they cannot move the thumb opposite the fingers of the same hand to grasp things tightly. This is why your dog would have trouble holding and manipulating a small object like a door key with his paws.

Depth perception --> Primates have an increased reliance on sight and decreased reliance on smell, compared to other mammals.  The eyes are large and forward facing, which provides better depth perception. The nostrils are smaller in relation to the face than in many other mammals.

Maternal care --> Primates have a smaller litter size, longer gestation, and extended period of juvenile growth compared to other mammals.  Most primates have one or two offspring at a time. They also exhibit increased periods of maternal care for their young compared to that of other animals.

Large brains --> Primates have relatively large brains. Primates have larger brains, relative to their body size, than most other mammals.

Which type of transport requires energy to move molecules from an area of lower
concentration to an area of higher concentration?

Answers

Answer:

active

Explanation:

Using energy, active transport is the process of moving materials into, out of, and between cells.

What is active transport?

Passive transport, which utilizes no energy, can be used in some circumstances to move substances. The cell must frequently move elements against their gradient of concentration, though. Active transportation is necessary in these situations.

Most frequently, a transport protein that attaches to the chemical known as adenosine triphosphate, the cell's "fuel," changes shape to carry out active transport (ATP).

In some circumstances, energy-free passive transport can be used to achieve this.

Therefore, the cell frequently needs to transfer an object against its concentration gradient. Active transportation is necessary in these situations.

what physical health risks are directly associated with urban sprawl?​

Answers

Answer:

The risks of various pollution and infections increase with urban sprawl.

Urban sprawl can be described as a condition in which the people from urban area migrate to low residential areas due to which the city starts to expand more in size.

During urban sprawl, more water contamination is likely to be caused as the water available cannot support such a large number of migration. There is not proper sewage system due to which contamination arise and cause sickness in the people. Also, these areas have more pollution due to traffic jam situations which causes sickness.

Answer:

The physical health risks that are directly associated with urban sprawl is pollution and infections.  During an urban sprawl, there are increased chances of water pollution and poor drainage system which can ultimately affect a population because the water can release toxins into one's body, which can cause diseases and illnesses. The respiratory system will get affected because when there is a population increase, the amount of air pollutants release would increase giving chances to lung cancer and breathing problems.

2. When is glucose generated?

3. What is the chemical formula for photosynthesis?

4. Did the complete process of photosynthesis take place in the way you modeled it in this activity? Explain your answer.

Answers

Explanation:

The process of photosynthesis is energy-storing because the process converts light energy into chemical energy, which is stored in the bonds of glucose.

6CO2 + 6H20 + (energy) → C6H12O6 + 6O2

Further Explanation:

Photosynthesis is a chemical pathway, integral to plant and other primary producers producing energy. Energy is produced from light, water and carbon dioxide in the form of glucose molecules while the oxygen is emitted.

Photosynthesis, which occurs in several complex steps, is a rate-limited reaction, depends on several factors including concentration of carbon dioxide, ambient temperature, and light intensity; energy is recovered from photons, i.e. light particles, and water is used as a reducer. For those removed from photosystem II, water supplies the chlorophyll in plant cell with replacement electrons.

Therefore, water (H2O) split into H+ a by light during photolysis into H+ and OH-acts as a source of oxygen along with functioning as a reducing agent; it reduces the molecule NADP to NADPH by providing H+ ionsand produces molecules of the energy storage moleciule ATP through an electron transport chain. This occurs in the thykaloids, where pigment molecules like chlorophyll reside.

Later, in dark reactions, NADP and NADPH are used in the Calvin cycle where monosaccharides or sugars like glucose are produced after the modification of several molecules. These hold energy in their bonds, which can be released in respiration in the mitochondria.

Glucose production occurs after G3P production- a molecule of G3P, goes to the cytoplasm from the cycle, to form complex molecules and simple sugars like glucose.
