Divergent volcanoes tend to have which of the following characteristics? A. Explosive, producing large amounts of thermal energy B. Explosive, producing large amounts of ash C. Nonexplosive, producing large amounts of lava D. Nonexplosive, moving along the sea floor with continental drif

Answers

A. Explosive, producing large amounts of thermal energy


Volcanoes form at different plate boundaries because of the plates divergent and convergent nature. the plates are always in motion, however minimal they may be. When the plates move apart from each other, the magma from below comes up to fill in the vacant space and thus a volcano is formed. It may be the other way round also and that is the magma forces the plates to move away and this results in the formation of a volcano. When one of plates dives under another plate, then the pressure creates melting of the mantle and thereby forms magma which in turn creates volcanoes.

Answer : Option C) Non explosive, producing large amounts of lava.

Explanation : The divergent volcanoes has the tendency of being non-explosive in nature. They help in producing large amounts of lava. The lava production is increased in these volcanoes.

Explanation:

Fibrous proteins are, well, fibrous. They are fibers, think microtubules.

Jerome also had blood work done to confirm the MI. The presence of troponin, or cardiac enzymes such as CK-MB, are a positive indicator of an MI. Why is their presence at higher levels in the blood indicative of an MI?a. They are by-products of aerobic metabolism and if they are present in higher amounts in the blood it shows that the myocardium is working harder.
b. They are substrates for aerobic metabolism and if increased in the blood show that the cardiac muscle is not functioning normally.
c. These proteins are normally found inside cardiac muscle cells and if present in the blood indicate damage to the cells.
d. They are by-products of anaerobic metabolism (glycolysis) and if increased indicate that the heart is not receiving oxygen.

Answers

Answer:

c.These proteins are normally found inside cardiac muscle cells and if present in the blood indicate damage to the cells.

Explanation:

  • When there is a decreased blood flow to the heart or if a particular part of the heart stops working then this is known as myocardial infarction (MI) and due to this the heart muscle gets damaged.
  • There are several biomarkers that are used to evaluate the functioning of the heart and these are known as cardiac markers, an example of this is Ck-MB which is an isoform of creatine kinase.
  • The CK-MB isoform is found in the cytosol of the heart muscle cells and it plays a role in causing the movement of high energy phosphates in and out of the mitochondria.
  • If there is a damage to the heart muscle cells which usually occurs following a myocardial infarction CK-MB levels elevates in the blood for a short period of time and this indicates MI.

Explain the difference between an infection caused by a fungus and an allergy caused by a fungus

Answers

Re-posting some old information I found on this website

When a fungus infects a body, it attacks the host by destroying and often taking over cells. When a person has an allergic reaction (to anything) the substance triggers the body to send histamines and excess water to the affected area, swelling and closing the area to prevent infection. - Answer Provided by ChaoticPiece
