Igneous rocks are formed by hot melted magma coming from the Earth's core that crystalizes when gets in contact with air. They can be either intrusive or extrusive. B) <em>Large mineral crystals.</em>
<h3>
What is the igneous rock?</h3>
These rocks come straight from the interior of the Earth.
A liquid mass of silicate composition comes from the Earth's core. This melted mass comes at an extremely high temperature.
Magma begins to cool and solidify during its ascent to the Earth's surface. It solidifies and crystallizes into igneous rock following the magnetic field orientation.
Thre are two types of igneous rocks
• plutonic rocks ⇒ in areas close to the terrestrial crust ⇒ intrusive
• volcanic rocks ⇒ on the surface ⇒ extrusive
According to this description, the correct option is B. <em>Large mineral </em><em>crystals</em><em>.</em>

Answer:
The correct answer is The bridge between cystein which connects parts of a protein is stable but non covalent interaction.
Explanation:
Disulfide bond link the sulfhydryl group of two adjacent cystein residues in a protein structure.
Dulsulfine bond is stable but is not a non covalent interaction.Disulfide bond itself is a covalent interaction.
Answer:
The correct answer will be option- Glycolysis.
Explanation:
Gluconeogenesis is a metabolic pathway which synthesizes glucose from non-sugar precursors. This pathway is activated in the low concentration of glucose due to less intake or completely absent to conserve energy.
This pathway is somewhat the reverse of the glycolysis when excess energy is present as a result of glycolysis, gluconeogenesis is inhibited and when no energy is present, gluconeogenesis is activated.
Thus, option- glycolysis is the correct answer.
Answer:
The function of the pleura is to allow optimal expansion and contraction of the lungs during breathing. The pleural fluid acts as a lubricant, allowing the parietal and visceral pleura to glide over each other friction free. This fluid is produced by the pleural layers themselves.
