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 phrase describes air pressure?
decreases with denser air
decreases as altitude decreases
equals mass divided by volume
decreases as a result of fewer air particles pushing down
The phrase which best describes air pressure is: decreases as a result of fewer air particles pushing down.
What is pressure?Pressure can be defined as a measure of the force exerted per unit area of an object or physical body. Thus, it is usually measured in Newton per meter square and calculated by using this formula:
[tex]P = \frac{F}{A}[/tex]
Where:
P is the pressure.F is the force.A is the area.The types of pressure.In Science, there are different types of pressure and these include the following:
Hydrostatic pressureOsmotic pressure Filtration pressureAtmospheric (air) pressureIn conclusion, air pressure is also referred to as atmospheric pressure and it generally decreases due to fewer air particles pushing down on the surface of planet Earth.

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.

The flow of genetic information in molecular biology follows the following path, A) DNA is translated into protein B) DNA is transcribed into RNA which is translated into protein C) DNA is translated into RNA which is transcribed into protein D) RNA is transcribed into protein
Answer:
The Correct answer is DNA is transcribed into RNA which is translated into protein
Explanation:
The genetic information is unidirectional, from DNA to proteins. First, DNA is transcribed into an intermediary RNA molecule is known as transcription (TC), a further messenger RNA molecule (mRNA) is translated into a corresponding sequence of amino acids (translation). This concept of information flow is known as the central dogma of molecular biology.

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.

what is semi conduction
Explanation:
Semi-conductive describes a component which conducts electricity less well than a good conductor but better than an insulator.
The hose should be semi-conductive, with a resistance high enough to insulate a stray current but conductive enough to get rid of static charge build-up.
Carbon black can be used to lower the resistivity of plastics, imparting antistatic, semi-conductive, or conductive properties.
Semi-conductive describes a component which conducts electricity less well than a good conductor but better than an insulator.

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"
