The passive movement of particles from a region of higher concentration to a
region of lower concentration is known as...
A. Diffusion
B. Active Transport
C. Osmosis
D. Selective Permeability
Answer:
Answer is A. Diffusion
Explanation:
Because diffusion is a passive process in which a substance moves from a higher concentration to a lower concentration until the concentration becomes equal
The passive movement of particles from a region of higher concentration to a region of lower concentration is known as diffusion. Thus, the correct option is A.
What is Diffusion?Diffusion may be defined as the passive movement of particles from a region of higher concentration to a region of lower concentration.
Active transport requires energy for the movement of particles. Selective permeability may be defined as the ability to differentiate the movements of different types of particles in and out of the membrane.
Therefore, the correct option for this question is A.

Why do planets close to the sun have thin atmospheres and the planets far away from the sun have thick atmospheres. Use what you know about the nebular theory.
Answer:
There are two primary factors: size and distance from the Sun. Gravity helps planets and moons to hold on to their atmospheres, so small planets/moons such as Mars and the Moon have thin atmospheres. The reason why the outer planets are larger is probably down to two major factors. The first is simply the amount of material available which may be accreted to a planet. Clearly, the further away from the Sun, the longer the orbit (twice as far means an orbit twice the physical length).

Explanation:
Plz help me with this question!!!!!!
Solution : It is a mixture of solvent (Major component mostly liquid) and solute (Minor component).
It is asking from a solution where water and solute are moving whether outise or inside.
_____________________________________As Per Hint Given:Solute ; Moves from higher concentration to the lower concentration by the process of diffusion.Solvent(Water) ; Moves from low solute area to the high solute area by the process of osmosis._____________________________________ROW 1 :26: Inside the cell (because inside the cell there is 5% solute(salt) whereas outside the cell it is 10%)
27: Outside the cell (outside the cell there is more concentration of salt so water moves out)
ROW 2:In Row 2 there is equal amount of salt outside and inside the cell so Solute and Solvent do not move because the solution is ISOTONIC
28: NO MOVEMENT
29: NO MOVEMENT
ROW 3:30: Glucose moves outside the cell
31: Water moves inside the cell (because glucose is more inside the cell)
ROW 432: Outside the cell (same reasons as above)
33: Inside the cell
ROW 534: NO MOVEMENT

A
B
C
Answer: Respiration
Explanation:
Cellular respiration is the process by which nutrients such as glucose are broken down using oxygen to generate energy in the form of ATP, that is used to drive cellular processes.
ATP consists of an adenosine molecule bonded to three phosphate groups in a row. Energy from cellular respiration is stored in the bond between the 2nd and 3rd phosphate groups of ATP.
When the cell needs energy to do work, ATP loses its 3rd phosphate group, releasing energy stored in the bond that the cell can use to do work.

Which is not a unique property of water
Answer:
A
Explanation:
All of the other options are specific to water, but quite a few liquids cool off a lot faster than water.
water cools very rapidly is not a unique property of water. Thus option A is correct.
what are the properties of water molecule ?It has no taste, odor, or transparency, where the nucleus of the oxygen atom attracts electrons strongly than the nuclei of the hydrogen atoms.
In water molecule oxygen is more electro negative and electron-greedy than hydrogen, results in the development of a partial negative charge on the oxygen of the water and a partial positive charge on the hydrogen end.
Water shows strong cohesive property where the attraction of molecules for other molecules of the same kind is referred to as cohesion.
Surface tension is defined as the tendency of the surface to resist rupture when they are subjected to stress due to cohesive forces.

The number of waves passing the observer per second is:
- the wavelength
- the amplitude
-the frequency
- the period
Answer:
frequency
Explanation:
comment if im wrong
The number of waves passing the observer per second is the frequency. Hence, the correct option is C.
What is frequency?Frequency refers to the number of waves that pass from a fixed point in unit time. It is a measure of the rate of repetition of a periodic phenomenon such as vibration or a wave.
It is measured in hertz (Hz), an international unit of measure where 1 hertz is equal to 1 cycle per second. The more cycles that occur per second, the higher the frequency of the system is.
For example-The human heart beats at a frequency of 68 beats per minute.
In general, frequency is a very important concept in many fields including physics, engineering, music and the natural sciences, and it is used to describe and analyze a wide range of periodic phenomenon.
Therefore, the correct option is C i.e., frequency.

Methamphetamine increases the brain's levels of dopamine, __________ and __________.
a) norepinephrine, serotonin
b) GABA, epinephrine
c) acetylcholine, enkephalins
d) glutamate, serotonin
Answer:
a) norepinephrine, serotonin
Explanation:
Neurotransmitters are special lipid-based molecules used in chemical signal transduction in the nervous system. They have receptor-specific roles in activating different regions of the central nervous system (CNS) and physiological responses. These include: dopamine, norepinephrine, and serotonin .
The CNS, which includes the brain and spinal cord, can be affected by certain drugs like methamphetamine. This drug is a stimulant that acts on brain regions such as:
prefrontal cortex the striatumthe nucleus accumbensIt causes the release of neurotransmitters while blocking their reuptake at synapses; meth is metabolized very slowly over time (12 hours). The buildup of dopamine, for instance, leads to altered moods, feelings of pleasure and euphoria.
Thus, this change or "high" leads to dependency by users for its mood-altering effect; however, less dopamine is released, and the pleasurable effects, become less potent. Studies show neurological damage with prolonged use, and habit formation and over time, addiction.

Mutations can be either spontaneous (no known cause) or induced (caused by specific environmental agents). What are some environmental agents that could increase the rates of genetic mutations among humans today? What types of mutations have the potential to be the most significant from an evolutionary perspective?
Answer:
Explanation:
Mutations happen spontaneously. The rate of mutation can be increased by environmental factors such as UV radiation , X-rays, gamma rays and certain types of chemicals such as bromine. These are some factor that can increase the rate of mutation
The classic example of evolutionary change in humans is the hemoglobin mutation named HbS that makes red blood cells take on a curved, sickle-like shape. With one copy, it confers resistance to malaria, but with two copies, it causes the illness of sickle-cell anemia. Examples of beneficial mutations include HIV resistance, lactose tolerance, and trichromatic vision.
Explanation:
Look the Mutations happen spontaneosly.So this means that this can increased by the enviromental factors such as Uv radiation, The X-rays, The Gamma Rays, and for last one the certain types of chemicals such as a bromine.These are some factors that increase the rate of the mutation.
So and here is the answer that you was looking for your answer was What are some environmental agents that could increase the rates of genetic mutations among humans today? well im here for teach you and told you or explain you whatever you wanted to call ir im here for teach you The evolutionary change that are in humans is that thing how is called? yes the Hemogoblin and you will say what is that thing why i want to know what is Hemogoblin Well you have to know that that think the hemogoblin is a mutation names "HBS" that makes the red blood cells it's for that reason that is important the "HBS" but there is the bad thing about the hemogoblin it makes the Anemia that is one of the terrible things that can happen to you ok?. Look they are good and bad thing about the Hemogoblin Im going to leave you some good and bad things about the hemogoblin: (But there are things that you have to know first the normal hemogoblin is in your DNA and in your DNA it's called G A G and it has too the C T C in your RNA it's called G A G and finally it nakes the GLU The GLU it's the normal Protein, but the hemogoblin can mutate the cell can get sick and the letters that are like This G A G those are going to change:
C T C They going to change like this:
(mutated)--- -- G T G
C A T (The RNA alsi change) G U G

\/
Val
(Original No mutated)---- G A G
C T C
G A G

(GLU)
The GLU is the Original Protein but the Val is the mutated Protein.
Now im going to say good and Bad thing about the Hemogoblin.
Good Things
N1:It creates the Blood cells
N2:Lactose Tolerance
N3-and also the Hemogoblin includes the HIV that is a resistance
Bad things about the Hemogoblin
N1-One of the most bad things of the hemogoblin is the Anemia that is the worst things as i say that can happen to you
and that's all you have to know
