Stage 1 sleep is characterized by a predominance of ________ wave activity in the brain.
Answer: theta
Explanation:
Stage 1 sleep is characterized by a predominance of alpha and theta wave activity in the brain.
The stage of entering the state of sleep is also called stage 1 and is considered as a boundary between the waking state and sleeping.
In this stage, the rhythm alpha predominates, which tends to slow down and show the presence of waves called theta, which are of greater amplitude.
Alpha activity is a pattern that results from a person resting and relaxing.
Theta waves are broad, low-frequency waves that would indicate a state of extreme relaxation and drowsiness.
Eye movements at this stage are slow and muscle tone drops. Phase I is short-lived and occupies about 3-5% of sleep.
Therefore, we can conclude that in stage 1 of sleep the alpha waves would be combined, with a new activity, called theta.

Which of the following represents the impacts of drilling and fracking on human health?
I. Heavy metal exposure can cause nervous system damage.
II. Air pollution can aggravate respiratory conditions.
III. Noise pollution can cause headaches, changes in sleep patterns, and anxiety.
- III only
- I and II
- II and III
- I, II, and III
Answer:
II and III
Explanation:
I only applies to mining and not drilling.
The correct answer as to the impacts of drilling and fracking on human health includes nervous system damage as a result of heavy metal exposure, respiratory diseases as a result of air pollution, and headaches, changes to sleep patterns, etc. as a result of noise pollution. The correct answer would therefore be I, II, and III.
Drilling and fracking are innovative technology methods used in the location of water, minerals, and the extraction of crude oil from underground respectively. The methods are characterized by the noise of the drilling machine, air pollution by dust particles as a result of soil excavation, and heavy metal pollution of the environment.The different pollutions have varying degrees of effects on the health of human and these include damages to the nervous system by heavy metal, damages to the respiratory organs as a result of inhalation of particulate matters and headaches/anxiety as a result of noise pollution.Hence, all the three effects represent the impact of drilling and fracking on human health.

How many electrons are contained in a single covalent bond
hi <3
there would be 2 electrons. each atom shares an electron each so in a single covalent bond, there would be 2 electrons
hope this helps :)
There are two electrons in a covalent bond.
Deeper meaning:-A covalent bond can be meant of as a 'shared pair' of electrons, so there are 2 electrons in each bond. This means that a double bond will have 4 electrons in the space between the bonded nuclei, and a triple bond will have 6.

Due to the partial charges on atoms in a water molecule, ____ in water molecules are attracted to oxygen atoms in other water molecules.
Hydrogen bond in water molecules are attracted to oxygen atoms in other water molecules.
A hydrogen bond is a strong dipole-dipole attraction which occurs between:
the hydrogen atom attached to a strongly electronegative atom (for example oxygen in water molecules)another strongly electronegative atom with a lone pair of electronsHydrogen bonding occurs in the following compounds which include water, hydrogen fluoride and ammonia.
When an electronegative atom such as oxygen is bonded to hydrogen, a dipole develops causing the hydrogen to be partially positive while the other atom is partially negative.
Thus, this accounts for high boiling point in compounds that contains hydrogen bonds.

A person lives on the Tropic of Capricorn. What is the altitude of Polaris?
O 23 1/2"
O 90°
O 66° 33"
O 15°
O 30°
O 45°
The correct answer as to what the altitude of Polaris would be for a person that lives on the Tropic of Capricon is 23° 1/2".
Polaris is a star and the altitude of any star is its height above the horizonThe Polaris is otherwise known as the North star as an indication that it is directly located overhead the north pole. Thus, it may not be visible once one moves South of the equator. The tropic of Capricon is located approximately 23° 1/2" South of the equator. In other words, the latitude of the Tropic of cancer is approximately 23° 1/2".Hence, the altitude of the Polaris at an altitude of 23° 1/2" will also be 23° 1/2", although it will most likely remain invisible.A person that lives on the Tropic of Capricon is approximately on latitude 23° 1/2". Since the altitude of a star is its height above the horizon, the altitude of Polaris from the Tropic of Capricon would, therefore, be 23° 1/2"

Nitrogen-fixing bacteria are prokaryotic organisms that transform nitrogen gas into nitrogen compounds like ammonia and nitrates.
The graph that correctly shows the nitrogen-fixing bacteria in the soil is graph 2.
Nitrogen-fixing bacteria can be explained as:
Nitrogen-fixing bacteria are the organisms that fix the atmospheric nitrogen into the compounds of nitrogen as ammonia and nitrates.The conversion of the atmospheric nitrogen is done in two steps, the first step involves the conversion of atmospheric nitrogen to ammonia. The second step involves the conversion of ammonium to usable nitrate. Graph 2 represents the amount of atmospheric nitrogen decreasing with an increase in the amount of ammonia. It indicates that atmospheric nitrogen is utilized and converted into nitrogen compounds.
Thus, the correct answer is graph 2.
