The number of waves passing the observer per second is:
- the wavelength
- the amplitude
-the frequency
- the period

Answers

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.

A

C

Answers

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

Answers

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.

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.

Answers

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).

Methamphetamine increases the brain's levels of dopamine, __________ and __________.

a) norepinephrine, serotonin

b) GABA, epinephrine

c) acetylcholine, enkephalins

d) glutamate, serotonin

Answers

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 accumbens

It 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.

If a man is color blind (an X-linked trait), how did he get this condition?
He got it from either his mom or his dad.
He got it from both his mom and his dad.
He got it from his dad.
He got it from his mom.

Answers

Answer:

He got it from his mom.

Explanation:

An X-linked trait means it is transmitted on the X chromosome.

Females have two X chromosomes (XX), and males have one X and one Y chromosome (XY).

Males get their Y chromosome from their dad, and X chromosome from their mom.

Therefore, the man inherited the colorblindness trait (X chromosome) from his mom

ANSWER:_____________________________________

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)

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

Answers

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.
