Which land feature supports the theory of continental drift?
canyons
volcanoes
coal fields
Oceans
Help plz
Answer:
The correct option is;
Canyons
Explanation:
The theory of continental drift, which was a 1596 hypothesis of Abraham Ortelius, is that the continents on Earth have had relative motion with one another over a period of geologic time such that the continents looks to haven drifting motion over the bed of the ocean
Evidence of the motion of the continents was first presented by Alfred Wegener in 1912 and continuing exploration of the ocean floor by Harry Hammond Hess has revealed that the there are lots of canyons, sea mountains such that the crust of the Earth moved apart on the facing sides of the ocean ridge which where evidence of sea floor spreading supporting the theory of continental drift.

The fuel for nuclear power plants comes from
Answer:
Most nuclear reactors are fueled with a compound known as uranium dioxide. This uranium dioxide is put together in a fuel assembly and inserted into the nuclear reactor—where it can stay for several months or up to a few years. While in the reactor the fuel undergoes nuclear fission and releases energy
Explanation:
Answer:
Uranium is the most widely used fuel by nuclear power plants for nuclear fission. Nuclear power plants use a certain type of uranium—U-235—as fuel because its atoms are easily split apart. Although uranium is about 100 times more common than silver, U-235 is relatively rare at just over 0.7% of natural uranium.

Answer:Integral proteins
Explanation: according to a video lesson in Founder Education
Integral proteins present in the cell membrane help in the transportation of materials and the signaling of other cells.
What are integral proteins and their functions?Integral proteins are the proteins attached permanently to the plasma membrane and are embedded in the whole layer of the membrane.They are also known as intrinsic proteins.Functions of intrinsic proteins:Transportation: Hydrophilic compounds may be able to get through the cell membrane due to intrinsic proteins.Signal transduction: A binding site may be present in certain membrane proteins. These binding sites have distinctive structures that closely resemble those of chemical messengers. A receptor membrane protein that is placed inside the cell wall will link with a hormone when it comes into contact with the cell wall. Depending on the type of hormone or other chemicals, the hormone can alter the receptor protein and induce a certain reaction to occur inside the cell.Learn more about membrane proteins here:

Some viruses can be crystallized and their structures analyzed. One such virus is yellow mottle virus, which infects beans. This virus has a single-stranded RNA genome containing about 6300 nucleotides. Its capsid is 25-30 nm in diameter and contains 180 identical capsomeres.If the yellow mottle virus begins its infection of a cell by using its genome as mRNA, which of the following would you expect to be able to measure?
A) replication rate
B) transcription rate
C) translation rate
D) formation of new transcription factors
The correct answer is 9 proteins form each of the 20 facets of this virus. A capsid is the protein shell that surrounds a virus. A capsomere is the subunit of the capsid. Depending on the virus, capsomeres arrange in many different shapes to form the capsid. The yellow mottle virus has 20 facets, this means that it has an icosahedral capsid. Since it contains 180 identical capsomeres, we can conclude that 9 proteins form each facet.

a solid used during photosynthesis.
a gas used during photosynthesis.
a liquid produced during photosynthesis.
a gas produced during photosynthesis.
Answer:
The correct option is;
A gas produced during photosynthesis
Explanation:
The chemical reaction of photosynthesis is given as follows;
6CO₂(g) + 6H₂O(l) + Energy from light → C₆H₁₂O₆(s) + 6O₂(g)
Therefore, six molecules of gaseous carbon dioxide (CO₂) combine withe six molecules of liquid water (H₂O) in the presence of energy from Sunlight to produce one molecule of solid glucose (C₆H₁₂O₆) and six molecules of gaseous oxygen (O₂)

While you and your classmate are studying for your biological anthropology midterm, your classmate tells you that the bones of Lucy, a famous australopithecine specimen that dates to about 3.2 million years ago, were dated based on carbon-14 analysis. Why is this incorrect?
The options for this incomplete question are :
Fossils are living organisms that have wholly or partially been transformed into rock.
Lucy does not have bones with organic material necessary for carbon-14 dating.
This specimen is also far too old for C-14 dating to be accurate, as well as for any other technique but palaeomagnetic dating.
Your classmate is therefore incorrect for all of the reasons listed. (All of the above)
Answer:
The correct answer is - all of the above reasons.
Explanation:
Fossils are living life forms that have completely or mostly been changed into the rock during the process of fossilization. Lucy doesn't have bones with organic material that are essential to use the carbon 14 dating technique.
This example is additionally very old for C-14 dating to be exact, just as for some other method, however, palaeomagnetic dating can do the job of dating in this case.
Thus, the correct answer is - all of the above reasons.

The pathogenesis of tuberculosis includes the entrance of mycobacteria into the lungs and the resulting of which of the following? (Select all that apply.) Calcification Ghon tubercles Formation of granulomas Activation of macrophages Antigen-antibody complexes
Answer:
The macrophages have a in the calcification process, which generates the inflammatory processes. The Ghon tubercles is a lung lesion caused in tuberculosis that consists of a focus of calcification in conjunction with a lymph node infection. A granuloma is a mass of immune cells that forms when the immune system tries to isolate foreign substances.Macrophages can be activated by a variety of stimuli during the immune response. The antigen-antibody (Ag-Ac) reaction is one of the molecular reactions in the body's immune response.Explanation:
Tuberculosis is a disease caused by Mycobacterium tuberculosis, a bacterium that almost always affects the lungs. When the active form of the disease is present, symptoms (cough, fever, night sweats, weight loss, etc.) can be mild for many months. If not treated properly, Tuberculosis can be fatal.
Macrophages are a type of white blood cell found in the blood and they are the first body's defense against foreign substances. So they are effector cells of the immune system, the main players in the innate immune response.
When M. Tuberculosis infects a person, it attacks this first-response immune cells in the lungs, the macrophages. When they recognize these pathogens, macrophages produce the cytokines IL-1 and TNF-α, which cause the inflammation itself by acting on the endothelial cells of the nearby blood vessels to allow the transendothelial migration of the leukocytes. The inflammation t is a non-specific response to environmental aggressions, and its purpose is the isolation and destruction of the damaging agent, as well as repairing the damaged tissue or organ.
The macrophages have a in the calcification process, which generates the inflammatory processes. The Ghon tubercles is a lung lesion caused in tuberculosis that consists of a focus of calcification in conjunction with a lymph node infection. These lesions are especially common in children and may retain viable bacteria, so they are sources of disease transmission and may also be associated with classic tuberculosis reactivation after several years of inactivity.A granuloma is a roughly spherical mass of immune cells that forms when the immune system tries to isolate foreign substances that it has been unable to eliminate. Therefore it is a special type of inflammation that can occur in a wide variety of diseases. Infections that are characterized by granulomas include tuberculosis, but also include for example leprosy, histoplasmosis, cryptococcosis, coccidioidomycosis, blastomycosis, and cat scratch disease.Macrophages are usually in a resting state, they can be activated by a variety of stimuli during the immune response. Antigen phagocytosis serves as an initial stimulus; however, macrophages and their activity can be increased by cytokines secreted by, or through contact with, helper T-lymphocytes. One of the most powerful macrophage activators is gamma interferon. They are also able to recognize molecular patterns associated with pathogens. M. tuberculosis is a pathogen that contains Pathogen-associated molecular patterns (PAMPS), which are small sequences of molecules that repeat in groups of pathogens. They are recognised by Pattern-recognition receptors (PRRs), which include the Toll-like receptor (TLRs) family or the NOD-like receptors (NLRs). Once the receptors found in the macrophages recognize these PAMPS, the macrophages are activated are ready to perform an immune response.The antigen-antibody (Ag-Ac) reaction is one of the molecular reactions in the body's immune response. The concept refers to the specific binding of an antibody to an antigen to inhibit or delay its toxicity. When the macrophage recognizes a pathogen, it phagocytes it and degrades it, and presents its peptides to a T cell. This can activate a cytotoxic response, causing apoptosis of infected cells. Or, the T cell may activate a B cell to produce antibodies. Antibodies are proteins whose function is to detect any foreign elements that may enter the body. They normally detect specific parts of these elements, for example, proteins from the surface of bacteria or viruses. When antibodies bind to these foreign proteins, they act as a marker, making it easier for them to be recognised and eliminated by the cells of the immune system.Has the Clements successional theory been subjected to peer review and publication?
Answer:
Yes the Clements successional theory has been subjected to peer review and publication
Yes, the Clements successional theory been subjected to peer review and publication.
What is Clements successional theory?Plant succession was characterised by Clements as a developmental process that, during the course of a community, it went through a well-defined series of stages that, in the end, resulted in a mature community, also known as the climax community. The climatic conditions that determined the climax community's existence manifested themselves in the form of an indicator and an expression of that community.
His hypothesis of community formation, sometimes known as plant succession, is what brought Clements the most fame. Even after World War II, Clements' organicism and physiological perspective were still around, albeit in a watered-down version, despite the fact that it was extensively discredited by later ecologists.
