Answer:

Slab pull occurs where older, denser tectonic plates sink into the mantle. As these older sections of plates sink, newer and less dense sections of plate are pulled along behind. Sinking in one place leads to plates spreading apart in other places. Earthquakes and volcanoes are primarily found at plate boundaries .

Explain the difference between types of scientific investigation

allsm [11]

Answer:

Hey there.

There are three types of scientific investigations: descriptive, comparative, and experimental scenitific investigations.

fist we have Descriptive scientific investigations.

Descriptive investigations use careful observations and measurements to develop findings.

Then we have  comparative Investigation.

comparative investigations Involve collecting data on different populations/organisms, under different conditions (Times of year, locations), to make a comparison. for Example, Using a hand lens to examine the color and texture of four different rocks.

Lastly we have experimental scientific investigations.

Experimental investigations involve a process in which a "fair test" is designed and variables are actively manipulated, controlled,

Cell theory states that all living things contain one or more cells. Why do you think cell theory meets the definition of

ziro4ka [17]

Answer:

Cell theory meets the definition of a scientific theory because it can be proven, it has been tested for a long period of time and therefore there are many evidences that support the theory but not enough to become a law. Well scientific laws are statements based on repeated experiments or observation, but also, a law is something that always applies under the same conditions. Evolution occurs in the characteristics of living things within a species overtime. . A theory is much more complex: it explains why something happens. A law only describes what happens.

The cell theory meets the definition of a scientific theory but i do not think it should be a scientific law.

When a person is exercising the body needs to deliver increased amounts of oxygen to the muscles. Which componentes f the blood

ad-work [718]

In human blood, there is a compound inside the RBCs called haemoglobin which ensures that the muscle will receive enough oxygen during exercise.

<h3>Explanation:</h3>

In human blood, the red blood corpuscles contain the haemoglobin. Haemoglobin is a iron chelated compound containing porphyrin ring and a globin tail which can establish co-ordinate covalent bond with both oxygen and carbon dioxide. The bonding element depends on the concentration of these two gases. In lungs, where the oxygen concentration is more than carbon dioxide, the haemoglobin bonds with oxygen and brings it to the tissues where carbon dioxide concentration is more. This makes the haemoglobin to release oxygen and bond with carbon dioxide which is brought back to lungs. This is the process by which each and every tissue including the muscles recieve oxygen.

In muscles there is Myoglobin which is another iron-porphyrin compound which has several times more affinity for oxygen than haemoglobin. This helps to extract more oxygen from haemoglobin in muscles.
