Answer:
Magnetism
Explanation:
The refrigerator doors are made of metal, and we use magnets to hold papers and photos on their surfaces. Magnets attract metals such as iron, cobalt, nickel, etc. That is due to the physical property of matter called magnetism, which is related to the attraction force generated by a magnetic field.

How is photosynthesis similar to cellular respiration? How do they differ?
Similarities Between Photosynthesis And Cellular Respiration
Similarities ...
→ Both involve in production of energy
→ Both involve the exchange of gases
→ Both the process takes place in cell organelle which was considered as endosymbiotic organism. They are chloroplast and Mitochondria, Photosynthesis takes place in Chloroplast where as respiration takes place in mitochondria.
→ At critical condition both have alternate pathway.
Differences...
→Photosynthesis takes place in chloroplast, where as respiration takes place in mitochondria.
→Photosynthesis involve production of carbohydrate and respiration involve breaking of carbohydrate.
→ Photosynthesis occur only during presence of sunlight where as respiration occurs all the time.
→ In photosynthesis process Oxygen is released where as in respiration Oxygen is utilised.
These are the main differences between Photosynthesis and respiration.

What might happen to the magma convection currents if there were no radiogenic heat produced in the core?
How would this affect life on Earth?
Plz help me
Answer:
If there were no radiogenic heat produced in the core, there would be no convection currents, and life on the Earth would not be possible.
Explanation:
The convection currents are the result of heating by temperature gradients. Differences in temperature and density produce these currents. Warm materials are lighter and can ascend, while cold materials are heavier and denser, so they tend to descend. These materials movements create a circular motion pattern known as convective currents. They occur in the atmosphere, in the water, and the Earth mantle. In the last case, while the hot material emerges from the bottom areas, the cold mantle sinks, creating a circular convection current. These play a significant role in fluids circulation and might be responsible for the movements of the lithospheric plates that are over the mantle. The temperature on the surface is much inferior that the mantle´s temperature, so the lithospheric pieces sink, creating a descendent current. Near the terrestrial core, the heat might reach up to 3,500ºC, and solid materials in these areas melt and fuse. When fusing, materials lose density, becoming lighter and ascending again to the surface, creating the ascending currents. The currents of ascending materials are known as thermal feathers or plumes.
Hot ascending material keeps the surface warm, making life possible. Also, radiogenic heat produced in the core is responsible for the electromagnetic field.
The electromagnetic field protects the Earth from many particles that come forward to the surface from space, specifically from the sun. The electromagnetic field also influences the atmosphere, keeping it in its place, necessary for life on Earth.
The plate´s movement produces earthquakes and volcanic activity. Both of them also necessary for many reasons, such as keeping fertile soils and producing necessary atmospheric gasses.
Through the years, the core losses heat, and eventually, it will become solid. When this happens, convective currents will stop because there will be no heat from the bottom to make them move. The electromagnetic field will disappear, and the atmosphere will be affected as well. The Earth surface will become cold. Mantle movement will stop, and there will be no earthquakes nor volcanic activities. Every living being on Earth will be affected by this fact. Life on Earth will not be possible.
Which graphic organizer is commonly used to compare and contrast ideas?
Venn diagram
mind map

problem-solution chart
Answer:
Venn diagram
Explanation:
The Venn diagram is a graphical organizer which is commonly used to compare and contrast ideas.
The Venn diagram is represented by several number of circle that represents different areas in order to compare one area to another. If the circles are overlapping it shows commonality or similarity between those both areas are. The Venn diagram makes easy to understand the difference or similarity between two areas.
Hence, the correct answer is "Venn diagram".

Normally, arteries are depicted in red and veins are depicted in blue. The pulmonary arteries are colored ______________________________ because they contain ______________________________ blood that flows to the lungs to pick up ______________________________ and unload ______________________________. The pulmonary arteries exit the heart from the ______________________________ (chamber). The pulmonary veins are colored ______________________________ because they carry freshly ______________________________ blood back to the ______________________________ (chamber) of the heart.
Answer:Normally, arteries are depicted in red and veins are depicted in blue. The pulmonary arteries are colored BLUE because they contain DEOXYGENATED blood that flows to the lungs to pick up OXYGEN and unload CARBONDIOXIDE. The pulmonary arteries exit the heart from the RIGHT VENTRICLE (chamber). The pulmonary veins are colored RED because they carry freshly OXYGENATED blood back to the LEFT ATRIUM (chamber) of the heart.
Explanation:
The circulatory system ensures a continuous flow of blood to all body cells. The heart is a muscular organ that is divided into four chambers which includes the right atrium, left atrium, right ventricle and the left ventricle.
The heart pumps blood into vessels that vary in structure, size and function and there are several types which includes:
--> arteries
--> arterioles
--> capillaries,
--> venules and veins.
The ARTERIES are the blood vessels that transport blood away from the heart. They are normally depicted in red because they carry oxygenated blood with the exception of the PULMONARY ARTERY which carries deoxygenated blood to the lungs.
The VEINS are blood vessels that return blood to the heart. They are normally depicted in blue with the exception of the PULMONARY VEIN because they carry deoxygenated blood from the lungs to the heart.

5 Clear Mark for Review Sacculina carcini is a barnacle that attaches to the underside of the green crab. The barnacle finds a hole in the green crab's exoskeleton, then uses microscopic hairs to feed on nutrients from the green crab's blood. The barnacle also lays its eggs in the green crab reproductive system, which sterilizes the green crab. Which term describes the role of S. carcini in this relationship?
Answer:
S. carcini is a parasitic barnacle species
Explanation:
Parasitism: In this case, one of the species is beneficiated, while the other suffers a consequence, reducing its fitness. These interactions are mostly about nutrition, although there might be other benefits too. Some parasite species might coexist with their host, while some others might get them ill to the point of causing death. Parasitic attacks might be very nocive, and even though they are not lethal in a short period of time, they might slowly kill the host.
Parasitic species consume part of the host, but not the whole body. They develop an intimate relationship with their host.
The Host increases the fitness of the parasite speciesThe parasitic species decreases the fitness of the host.By taking the nutrients from the green crab's blood and sterilizing it, the barnacle causes a decrease in the fitness of the crab. The crab becomes weaker and its survival chances decrease, and they have no opportunity to reproduce. Meanwhile, the barnacle gets stronger and reproduces normally.
