What are the two main ways that scientists learn about Earth's interior and what do these two things indicate?

Scientists use seismic waves from earthquakes to study the interior and the Earth's magnetic field. The seismic waves indicate the mantle is molten rock that flows like plastic, the outer core is completly molten rock, and the inner core is a solid ball of iron. The magnetic field indicates the inner core is spinning faster than the rest of the planet

The two main ways that scientists learn about Earth's interior is by studying the data collected by body waves and surface waves. The body waves travel in the interior part of the earth in all direction while the surface waves travel along the surface of the Earth. Now these body waves can travel through all liquids and solids while the surface waves can travel through only solids. The physical characteristics studied are density and state of material to which these waves respond and studying their seismographic recording would give a description of the composition of the Earth’s interior.

2.Which of the following is NOT an example of symbiosis? A. red blood cells containing malaria. B. vines using a tree for suppor

omeli [17]

Answer:

A. red blood cells containing malaria

Explanation:

Malaria is a disease-causing pathogen in humans. It is caused by species of the parasite Plasmodium sp., which is transmitted as sporozoites by the Anopheles mosquito upon biting the host. These travel through the bloodstream to the liver where they mature into merozoites. These reenter the bloodstream and mature into trophozoites and schizonts that produce more merozoites.

When they multiply within the red blood cell, they burst the red blood cell open, and go on to infect other cells. This infection's symptoms are cyclic and include high fever, chills and other flu-like symptoms.

Malaria is a deadly illness, causing harm to its hosts, and in many cases death. Thus, this cannot be defined as symbiosis, which is typically beneficial to both organisms.

Is simple diffusion a form of passive transport

Viktor [21]

Passive Transport: Simple Diffusion. Diffusion across a cell membrane is a type of passive transport, or transport across the cell membrane that does not require energy. ... Molecules that are hydrophobic, just like the hydrophobic region, can pass through the cell membrane by simple diffusion.

In C3 plants the conservation of water promotes _____.

bija089 [108]

Answer:

The correct answer is d. photorespiration

Explanation:

In the C3 plant, the Rubisco enzyme is important that fix CO2 into organic molecule by binding with CO2. Rubisco can also bind to oxygen when the oxygen concentration increases in cells which leads to the loss of fixed CO2 and waste of energy which is called photorespiration.

So when stomata are open CO2 comes in and O2 goes out of the cell which maintains the high CO2 concentration in the cell but during hot days C3 plants close stomata to prevent water loss.

So closing of stomata decrease the intake of CO2 and increase the oxygen concentration inside the cell. So in increased temperature and high oxygen concentration, the rubisco enzymes bind to O2 and promote photorespiration.
