Answer:
Locked up in rocks
.
Explanation:
The volcano consists of the high melted lava that are present in the rupture of the earth's crust. The disturbances and movement in the tectonic plates might cause volcano eruption.
The volcanic eruption releases large amount of carbon dioxide, ash and harmful chemicals. The carbon dioxide that are erupted is locked in the rocks that are present on the earth's surface. The carbon dioxide is stored in the form of carbonates in the rock.
Thus, the answer is locked up in rocks
.
Answer: Point mutation
There are several different types of mutations possible in the base sequence of DNA. If a GGC (glycine) codon were changed to UGC (cysteine), it would be termed a point mutation.
Explanation:
Point mutation is caused when a nitrogenous base (purine or pyrimidine) is substituted by another base of the same or different class in a nucleotide. So, GGC (glycine) codon to UGC (cysteine) signifies the change of the first base - guanine to uracil.
Other types of mutation include insertion and deletion.
But in this case, point mutation is said to have occurred.
Answer:
it causes the depolarization of the target cell
Explanation:
Glutamate is an excitatory amino acid neurotransmitter that binds to specific receptors on the surface of target cells and thus causes its depolarization. During glutamate-mediated depolarization, the difference in charge inside and outside the cell is lost due to the entry of sodium and calcium positive ions into the postsynaptic cell (neuron) through specific ion channels. Moreover, glutamate binding also leads to the exit of potassium ions from the cell, thereby resulting in excitation. Through this mechanism, glutamate regulates many signaling pathways, such as those involved in memory, learning, emotions, cognition, motor control, etc.
