Answer:
Sea floor spreading-> <u><em>Oceanic ridge and Magma pushing two plates apart</em></u>
Continental drift-> <u><em>Concept of pangaea and Oceanic plates sliding under continental crust</em></u>
Explanation:
Due to the divergent plate movement, the magma come out to the surface, forming the mid oceanic ridge and this separation of plates on the sea floor is known as the sea floor spreading. The magma here pushes the two plates to move apart because of the convection current that generates in the mantle. One example of mid oceanic ridge is the Mid-Atlantic Ridge.
Continental drift refers to the slow and gradual movement of the lithospheric plates over the viscous asthenosphere layer. This motion of continents takes place because of the plate tectonic movement. Due to this plate motion, the denser plate gets subducts beneath the less denser plates. For example, the oceanic crust when collides with a continental crust, it gets subducted because of its higher density. The great supercontinent "pangaea" also formed and separated due to this plate motion.
Answer:
The ratio is 6 to 1
Explanation:
1. a 6 sided cube of 1 mM has a volume of L * W* H (1*1*1=1) 1 mM.
2. a 6 sided cube has a surface area of one face surface area times 6 or (L * W) * 6 = 1mM * 1 mM * 6 = 6
so the ratio of surface to volume is 6/1.
Answer:
The scientific name or the binomial nomenclature has a number of advantages over using the common names. 1. Organise and classify - the organism can be easily categorised, this really helps making it easier to understand the characteristics of a specific organism in an organised chart.
Explanation:
In adrenocortical insufficiency, such as Addison's disease, the most severe manifestations are the result of an insufficient amount of circulating cortisol.
Addison’s disease is an uncommon chronic condition in which the adrenal glands fail to produce sufficient amount of hormones including cortisol and aldosterone. It results often from an autoimmune attack.
Cortisol is a hormone which assists the body in dealing with stress such as the stress of an illness, injury or surgery. It also helps in regulating the blood pressure, cardiac function, immune system and blood glucose or sugar levels.
Aldosterone is a hormone which affects the balance of salts like sodium and potassium in the blood which in turn controls the amount of fluid that the kidneys can remove as urine.
