Answer:
Wegener suggested that perhaps the rotation of the Earth caused the continents to shift towards and apart from each other. (It doesn't.) Today, we know that the continents rest on massive slabs of rock called tectonic plates. The plates are always moving and interacting in a process called plate tectonics.

why does the respiratory system require two organ systems
Answer:
The lungs expel the carbon dioxide and bring in new oxygen-containing air. Only when both systems are working together can oxygen and carbon dioxide be successfully exchanged between cells and environment. There are many other examples of this cooperation in your body. :)

what is the function of silkworm?
Answer:
The silkworm is the larva or caterpillar of a silk moth. It is an economically important insect, being a primary producer of silk. A silkworm's preferred food are white mulberry leaves, though they may eat other mulberry species and even the osage orange
What type of contraction, concentric or eccentric, would cause more fatigue to occur in a muscle? Why?
Answer:
concentric
Explanation:
Eccentric contractions are lengthening movements of your muscles. During this muscle movement, your muscle fibers are stretched under tension from a force greater than the muscle generates. Unlike a concentric contraction, eccentric movements do not pull a joint in the direction of a muscle contraction.
Answer:
Eccentric contractions have recently shown to be caused greater low- frequency fatigue than concentric. This is because size of fall in the force from eccentric contractions carry out on fresh muscle is signifgantly larger. Explanation:
At the beginning of cellular respiration ____________________________ occurs, where glucose is broken down into pyruvate and ATP. This step does not require any oxygen.

. Which waves cause the most movement of the rocks during an earthquake?
A. surface waves
B. S-waves
C. P-waves
Answer:
A
Explanation:
There are two types of body waves: P-waves travel fastest and through solids, liquids, and gases; S-waves only travel through solids. Surface waves are the slowest, but they do the most damage in an earthquake.

How are food webs different to food chains? Explain why foodwebs are more useful
Answer:
Explanation:
A food chain is different because it shows what organisms eat in a straight line, in a chain. For example, a bird of prey can eat a snake that previously had eaten a frog and the frog ate a grasshopper and so on. But this tells us very little. A foodweb will tell us how all those animals are connected and what they eat in a web, not just a line.

when salt is dissolved in water, water is the what and why
Answer:
solvent
Explanation:
The solvent is the substance that dissolves another thing, in this case the water dissolves the salt
Answer: Water is the solvent because it is dissolving the salt in it. Salt is the solute.
if 40 carabaos live in a 4 sq. meter area,what is their population density per sq. km.?
Explanation:
Given parameters:
Number of carabaos = 40
Area of the place = 4m²
Unknown:
Population density = ?
Solution:
The population density of the place is the number of organisms per square km.
Mathematically;
Population density = [tex]\frac{number of Carabao}{Area}[/tex]
Population density = [tex]\frac{40}{4}[/tex] = 10carabaos/m²

Which of the following is one of the ways that cellular respiration and photosynthesis are opposite processes?
A.)Photosynthesis releases energy, and cellular respiration stores energy
B.)Photosynthesis removes carbon dioxide from the atmosphere, and cellular respiration puts it back.
c.)Photosynthesis removes oxygen from the atmosphere, and cellular respiration puts it back,
d.) Photosynthesis consumes glucose, and cellular respiration produces glucose.
Answer:
B.)Photosynthesis removes carbon dioxide from the atmosphere, and cellular respiration puts it back.
Explanation:
One of the ways in which photosynthesis differs from respiration is that photosynthesis removes carbon dioxide from the atmosphere and cellular respiration puts it back.
Photosynthesis is the process whereby green plants manufacture their food in the presence of sunlight using carbon dioxide and water. The product is usually glucose and oxygen. Respiration breaks down energy rich compounds into ATP, carbon dioxide and water.what type of wave must have a medium to transfer energy
Answer:
Mechanical waves
Explanation:
Mechanical waves are waves that must have a medium to transfer energy. Without a medium, mechanical waves cannot be propagated in space.
Electromagnetic waves on the other hand do not require a material medium for their propagation. They can move energy through a vacuum. Examples of mechanical waves are sound waves, water waves, seismic waves etcExamples of electromagnetic waves are x-ray, infrared, light waves.When the suns rays pass through our atmosphere and then heat is trapped by the atmosphere it is called?
