Granite is a type of intrusive igneous rock
Explanation:
An igneous rock formed from hot magma or lava cools, solidifies or crystallizes to form rocks.
Based on the rate of cooling of magma, igneous rocks can either be intrusive or extrusive.
A slow cooling of the magma deep within the earth without reaching the surface of the volcano leads to the production of intrusive igneous rocks.
This slow cooling leads to crystallization forming large crystals visible to the eyes with a phaneritic texture.
Granite has the best phaneritic texture among intrusive igneous rocks. Granite crystals can be easily visualized and are constituted by minerals like white feldspar, black hornblende, translucent quartz, and platy black biotite.
Extrusive igneous rocks like basalt are formed from microscopic crystals from fast cooling of magma.
Answer:
Animals release carbon dioxide into the air, and plants take it in.
Explanation:
The existence of plants and animals on the planet is important in maintaining life. Animals release carbon dioxide as waste through the respiratory system. The carbon dioxide that is released is then taken in by plants, which they use to produce their own food through a process called photosynthesis. The by product of that process is oxygen which is released in the atmosphere and animals take it in.
The trp repressor blocks transcription of the trp operon (B) when the repressor binds to tryptophan.
trp operon or the tryptophan operon codes enzymes for the amino acid tryptophan. The operon is on when the tryptophan is low in amount whereas the operon is off when the tryptophan is low in amount. The operon is an assimilation of five genes.
Repressor is a small protein that is supposed to prevent the synthesis of proteins. It does so binding to the operator gene. Therefore, presence or absence of repressor is a determining factor for an operon to be on or off.

The answer is none of the above
Answer:
Instead of a brain, echinoderms have a ring of nerves located around their mouth area that governs their nervous responses. This ring coordinates their motion, their eating, basically anything that requires nerve control.
