Why are plinian eruptions more violent than hawaiian eruptions?

Biology
1 answer:
OverLord2011 [107]3 years ago
8 0
One of the reasons why Plinian eruptions are more violent is that they release more viscous magma than Hawaiian hawaiian eruption. the thicker the magma the more violently it is released on the ground surface. Hawaiian eruption on  the other hand release thin magma that flows peacefully but fast. the other reason hawaiian eruptions are less violent is the presence of many side fissures where some magma escapes through in addition to the main vent. these fissures help to reduce pressure and therefore magma flows peacefully. in plinian eruptions magma is mainly released from the main vent.

How would someone measure the effect of pH on the rate<br> ofenzyme reaction?
wlad13 [49]

Answer:

It can be determined by measuring product appearance or reagent disappearance also enzymatic activity (described below )

Explanation:

Effect of pH on enzymatic activity

PH effect: affects the state of dissociation of the groups, although all proteins are not affected in the same way because some do not have dissociable groups. Most enzymes have an optimal pH. If there are small changes in pH, the enzyme is not denatured. The pH can affect in two ways:

The substrate binding is better or worse than before.

That affects the catalytic speed of the reaction.

The enzymatic speed is measured in M ​​/ t and the enzymatic activity in mol / t, and the international unit μmol / min, amount of enzyme that transforms a micromol from substrate into product in one minute under optimal conditions. Another unit is the enzymatic amount that is required to transform 1 mol / s and is called katal.

What are the differences between the endocrine and nervous systems?
son4ous [18]

Answer:

Explanation:

The endocrine system is a complex of glands that secrete <u>hormones</u> as a chemical messenger. These hormones carry information and instructions throughout the bloodstream from one part of the body to another. These hormones control many body functions such as respiration, sensory perception, metabolisms, growth, reproduction, the mood among others.

On the other hand, the nervous system is made up of neurons that communicate with each other to extend a message (from our own body or the outside) to the brain, for analysis and further decision of what to do with that information. A group of neurons, sensory neurons, respond to several stimuli such as touch, light, and sound to let the brain know about the surrounding environment. Another group of neurons, motor neurons, work inside the body and carry signals to active muscle or glands.
