Answer:

A. It contains fewer volatile gases.

Explanation:

Mafic lava have a composition of about 45-55% silica with high amount of Fe, Mg, Ca.

The silica content is quite low compared to those of granitic magma whose silica content can reach up to about 60%.

What determines the viscosity of magma is basically the silica content of the magma and the temperature of the magma. Viscosity is the resistance to flow.

The higher the silica content, the lower the viscosity and the higher the amount of volatile gases. Such type of magma is the granitic magma. Granitic magma due to their viscosity flows slowly.

The lower the silica content, the higher the viscosity and the lesser the presence of volatile gases in them. Such an example is Mafic magma. Mafic magma flows very slowly with low amount of dissolved gases.

Answer:

A. It contains fewer volatile gases

Explanation:

The mafic lava is a lava type that has low viscosity. The reason for that is its composition, being very rich in magnesium and iron. Because this type of lava is low in viscosity, it is unable to contain the majority of the gases and water in it, as they find it relatively easy to ''escape'' from it. That results in much calmer eruptions of the volcanoes that produce mafic magma, with explosions almost never occurring, and even if they do they are very small.

Please help asap, I will give brainliest!!!
sdas [7]

Answer:

Biodiversity is a variation of organisms (plants, animals and bacteria) in the world or a specific habitat. Biodiversity helps to keep an ecosystem healthy because there is more variation of food and different organisms can rely on each other for survival. Also it offers a larger more reliable food chain and if one species is suddenly wiped out, it won't impact the ecosystem as much as it would if the biodiversity was smaller.

Which of the following is NOT one of the functions of skeletal muscle? Which of the following is NOT one of the functions of ske
Rasek [7]

Answer:

regulation of the diameter of blood vessels and control of blood pressure

Explanation:

Skeletal muscles are the multinucleated muscles with striations and are attached to the bones (skeleton). The main function of skeletal muscles is to generate the voluntary movement of the body or body parts. The skeletal muscles of face, rectum, and urinary bladder generate their voluntary movement as per the will of the organism. On the other hand, blood vessels are lined with smooth muscles with spindle-shaped cells.

For example, the muscles present in the subcutaneous layer of the skin of the face are responsible for various facial expressions. Contraction of these facial muscles brings about the movement of skin of the face to generate a wide variety of emotions. Smooth muscles of blood vessels are involuntary in nature.

Vasodilation and vasoconstriction as brought about by smooth muscles of blood vessels are regulated by the autonomic nervous system. Under the conditions of lower blood pressure, contraction of smooth muscles of blood vessels restore the reduced blood pressure. On the other hand, when the blood pressure rises above the normal range, the smooth muscles of blood vessels relax to dilate them and to lower down the blood pressure.

Select the correct statements about cellular respiration. (Check all that apply)
kogti [31]

Cellular respiration is the process by which glucose is broken down to carbon dioxide and water in the cell.

Cellular respiration refers to the process in which glucose is broken down to produce energy. The reaction of cellular respiration is; C6H12O6 -----> 6H20 + 6CO2. This process occurs in the mitochondria of the cell which is within the cytoplasm. In times of oxygen deficit, lactate or ethanol may be produced by the process.

The following statements are true about cellular respiration;

  • lactate may be produced
  • ethanol may be produced
  • the reactions happen in the cytoplasm
  • CO2 is produced

Give an example of a direct and indirect interaction between two organisms
horsena [70]

Answer:

The example of direct interaction between two organisms is in coral reefs some fishes behave as a cleaner for the other fish.

Explanation:

The fish eats the parasites which harms the other fish. In this the cleaner fish gets food and the other fish gets rid of parasites. The example of indirect interaction between two organisms is when the birds eat the caterpillar, there is a positive impact on the plants because the Caterpillars used to the leaf of the plants.

The direct interaction between two organisms is defined as when the action of one organism has a direct impact on the other organism. The indirect interaction between two organisms is defined as when the action of one organism is responsible for indirect impact on the other organism.
