Volcanic domes commonly are partially destroyed when

Usimov [2.4K]3 years ago
7 0

When you have seen a land formation which is in the shape of a rough circular mound-shaped protrusion resulting from the slow extrusion of viscous lava from a volcano, then most probably what you are seeing is a lava dome or a volcanic dome. Some of these lava domes’ geochemistry vary from basalt to rhyolite. Although the usual content are those mentioned, most of the preserved domes tend to have high silica content. The sleep flanks can partially destroy the domes. These can result to the collapsing and breaking into a jumble of blocks and ash that flow downhill. These domes can also be destroyed due to the explosions inside them. This happens when trapped gas builds up so much inside that it can no longer be held.

What is the purpose of the pericardial sac that surrounds the heart in mammals
Nitella [24]

Answer:

Pericardial sac has protective tole

Explanation:

Pericardial sac or pericardium is a fibrous tissue that surrounds the heart. It has two coats:

  1. the outter coat-parietal pericardium
  2. the inner coat-visceral pericardium or epicardium which is double-layered and contains pericardial fluid between those two layers (pericardial fluid is necessary as a lubricant for the heart movement).

Besides lubrication, percardium also protects heart from infections, fixes it and limits its movements.

1) B
    (I'm not so sure of this one) All of the other options have a steady impact on population regardless of the density of organisms except competition

2) D
    Increased carbon dioxide levels would not hinder plant growth, and tsunamis aren't really linked to carbon dioxide levels. Increased carbon dioxide is unlikely to lower the air temperature so only D is left.

3) A

4) Three properties of water that allow it to sustain life are that it is adhesive, it is a good solvent, and cohesion. Adhesion is important in situations such as water travelling up xylem tubes in plants so that the water is not pulled down by gravity and can reach parts of the plant that need water. Cohesion allows the water being pulled up the xylem to stay together and for water molecules to be pulled when a neighbouring one is moved. Water being a good solvent allows inorganic minerals to be taken with water through vascular tissue, such as in the previous example.

Why is it essential that the regulatory mechanisms that activate glycogen synthesis also deactivate glycogen phosphorylase? (sel
Alex_Xolod [135]
This is because such a mechanism of regulation prevents the simultaneous addition and removal of glucose monomers, preventing unnecessary reactions. Additionally. the two processes occur in the same location in the sell, thus this regulation makes the net process more efficient. When glycogen phosphorylase is phosphorylated its activity increases and vicevarsa.
