Answer:
Group 1 - Alkali metals; Group 4 - Elemental Properties
Explanation:
The elements in Group 1 are called Alkali metals and those are: Lithium, Potassium, Rubidium, Celsium, Francium and Sodium and the elements in Group 4 are called: Titanium, Hafnium, Zirconium and Rutherfoundium.
It's important that group 4 has no trivial name like the group 1 does, it belongs to the grouping of <em>transition metals </em>and those metals have several general properties. They are found in the middle of the periodic table.
Answer:
The correct option is;
7:32 AM
Explanation:
The information given are;
The time at 45 degrees W and 72 degrees N = 9:32 AM
The variation of time with lines of longitude is given as 15 degrees for each 1 hour variation, therefore, where we have the other location at 75 degrees W and 45 degrees S, the difference in the longitude = 75 - 45 = 30 degrees west of the initial location
Moving west is in the opposite direction of the Earths rotation, therefore, we subtract 1 hour for every 15 degrees giving 30/15 = 2 hours subtracted
The time at 75 degrees W and 45 degrees S is therefore, 9:32 AM - 2 hour = 7.32 AM
The latitude of a place left out in the calculation of the relative time of a place.
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.
it wasn't just the earthquake that did damage. the magnitude of the quake caused a tsunami to form which hit shore and caused the more catastrophic damage.
