Answer:

The ability of caffeine to inhibit adenosine receptors, plays a very important role in heightened alertness and sleeplessness.

Explanation:

"<em><u>Caffeine</u></em>" (<em>1,3,7-trimethylxanthine</em>) is an alkaloid obtained from plants. It has a chemical formula of C8H10N4O2.

Caffeine is generally <em>hydrophillic</em> but sufficiently <em>lipophilic</em> to pass through all biological membranes and readily cross the blood-brain barrier.

Therefore can bind with the adenosine receptors. Due to the blocking of adenosine inhibitory effects through its receptors held by paraxanthine and caffeine, it indirectly affects the release of <u>norepinephrine, dopamine, acetylcholine, serotonin, glutamate</u> e.t.c.

The release of the above-mentioned hormones have a great impact on the heightened alertness of the body, especially <em>dopamine</em> and <em>serotonin</em>.

What is the name of the groove that forms in the middle of a dividing plant cell
mrs_skeptik [129]

Plants have cell walls, so cytokinesis cannot go on with a cleavage furrow, but instead, a cell plate  forms across the cell in the location of the metaphase plate.

There is no distinct groove along the cell plate as the cell divides because of the rigid nature of the cell plate or new cell wall.

A plant cell divides differently from an animal cell which forms a clear cleavage furrow because it only has a flexible cell membrane and not a rigid cell wall like plants.

The cell plate in plant cells is formed by membrane bound vesicles which migrate to the center of the cell where the metaphase plate used to be and fuse together to form a cell plate.

With your group members discuss and answer the following questions.
Yakvenalex [24]

1) One seismogram represents the distance to the epicenter (indicated by one circle). This is determined by the arrival times of the P and S waves. When the seismograph is near to a quake, the S-waves arrive shortly after the P-waves.

2) A single or double recording station could only measure distance, not direction; a full circle is drawn around the station to allow for all possibilities.

3) Triangulation is a technique used by scientists to determine the location of an earthquake's epicenter. When seismic data is collected from at least three different locations, the epicenter may be established by where the data links. A network of seismographs positioned in various directions records every earthquake.

4) A seismograph is a device used to record seismic waves caused by an earthquake, explosion, or another Earth-shaking event.

5) In the aftermath of an earthquake, the P waves go ahead of the S waves. As a result, the longer the time difference between the arrival of the P and S waves, the greater the distance between a seismic recording station and the earthquake epicenter.

6) Surface waves frequently induce more ground motion than body waves and hence cause more harm.

<h3>What exactly is a seismograph?</h3>

Seismometers are measuring instruments that detect ground noises and vibrations caused by earthquakes, volcanic eruptions, and explosions. Seismographs usually consist of a seismograph, a timing device, and a recording device.

Modern seismometers are capable of detecting ground movements as small as a few nanometres - a millionth of a millimeter. The magnitude of the earthquake is calculated using the measured amplitudes and its closeness to the hypocenter.
