Answer:
Seismic waves, Outer, Mantle
Explanation:
P-waves vibrate longitudinally to the direction of propagation while S-waves vibrate vertically to direction of propagation. This is why S-waves are called shear waves while P-waves are compressional waves. S-waves are the main cause of destruction in an earthquake and are slower than P-waves.
The wave movement of P-waves allows them to pass through liquids and gases while S-waves cannot. Due to this differential phenomenon of these waves, the reflection of P –waves and S-waves after an earthquake – and as their vibrations are picked up by seismographs around the earth - enabled scientists to determine the properties of the layers of the earth’’s interior.
There are two category of cell wall type and this are Gram-Positive and Gram Negative. The characteristic of the two is as follows;
Gram-Positive
Acidic polysaccharides on surfaces
Appears purple when stained
Thick peptidoglycan layer
<span>No porin proteins
</span>
Gram-Negative
Outer liposaccharide layer
Appears pink when stained
Thin peptidoglycan layer
<span>Has porin proteins</span>
Answer:
The correct answer is "USDA Appendix B".
Explanation:
The United States Department of Agriculture (USDA) have a series of Guidance Documentation that clarify the obligations that people must follow in order to properly handle agricultural products. The USDA Appendix B entitled "Compliance Guidelines for Cooling Heat-Treated Meat and Poultry Products (Stabilization)", states the procedure that must be followed to chill a product to reduce the growth of foodborne pathogens.
Answer:
Climate‐change‐induced shifts in plant species distributions are changing the characteristics of biomes (ecosystems with the same dominant plant life‐forms), altering structure and ecosystem functioning.
