3) the north Pacific Ocean

Explanation:

Maritime polar air is defined officially as: Maritime polar (mP) air masses are cool, moist, and unstable. Some maritime polar air masses originate as continental polar air masses over Asia and move westward over the Pacific, collecting warmth and moisture from the ocean

Basically it's the North Pacific Ocean because of the higher latitude and colder air temperature

H2O is polar covalent or its Hydrogen bond??? PLEASE HELP!!!

Answers

Answer:

Polar covalent.

Explanation:

The covalent bonds are therefore polar, and the oxygen atoms have a slight negative charge (from the presence extra electron share), while the hydrogens are slightly positive (from the extra un-neutralized protons). Opposite charges attract one another.

An animal cell placed in a hypertonic solution will shrink in a process called crenation. An animal cell placed in a hypotonic solution will swell and potentially burst in a process called hemolysis. To prevent crenation or hemolysis, an animal cell must be placed in an isotonic solution such as 0.9% (m/v) NaCl or 5.0% (m/v) glucose. This does not mean that a cell has a 5.0% (m/v) glucose concentration; it just means that 5.0% (m/v) glucose will exert the same osmotic pressure as the solution inside the cell, which contains several different solutes. A red blood cell is placed into each of the following solutions. Indicate whether crenation, hemolysis, or neither will occur.
Solution A: 3.21% (m/v) NaCl
Solution B: 1.65% (m/v) glucose
Solution C: distilled H2O
Solution D: 6.97% (m/v) glucose
Solution E: 5.0% (m/v) glucose and 0.9%(m/v) NaCl
Drag each solution to the appropriate bin.

Answers

Answer:

Solution A: 3.21% (m/v) NaCl  ⇒ CRENATION

Solution B: 1.65% (m/v) glucose  ⇒ HEMOLYSIS

Solution C: distilled H₂O  ⇒ HEMOLYSIS

Solution D: 6.97% (m/v) glucose  ⇒ CRENATION

Solution E: 5.0% (m/v) glucose and 0.9%(m/v) NaCl ⇒ CRENATION

Explanation:

Isotonic solution = 0.9% (m/v) NaCl or 5.0% (m/v) glucose

Crenation will occur if the solution has a concentration higher than 0.9% (m/v) NaCl or 5.0% (m/v) glucose (hypertonic solution). This will occur in the following solutions:

Solution A: 3.21% (m/v) NaCl  > 0.9% (m/v) NaCl

Solution D: 6.97% (m/v) glucose  > 5.0% (m/v) glucose

Solution E: 5.0% (m/v) glucose and 0.9%(m/v) NaCl (the addition of the 2 components exceeds the osmotic pressure permitted).

Hemolysis will occur if the solution has a concentration lower than 0.9% (m/v) NaCl or 5.0% (m/v) glucose (hypotonic solution). This is the case of:

Solution B: 1.65% (m/v) glucose < 5.0% (m/v) glucose

Solution C: distilled H₂O = 0% glucose/0% NaCl < 0.9% (m/v) NaCl or 5.0% (m/v) glucose

Describe in your own words how the earth's layers were formed.

Answers

Answer:It starts from the centre.The inner core.The outer core.The mantle .And the crust.They formed as the building blocks of earth.Knownas planetesimals collided and collapsed under Thier own gravity around 4.5 billion years ago

The layers of the earth were formed due to the sediments that significantly flattens out beside the center of the earth. After a long duration, a new layer is spread over the older layer, and so on.

What are the different layers of the earth?

The different layers of the earth are as follows:

The Inner Core: This is the first layer from the center of the earth. The Outer Core: It is found after the inner core. The Mantle: It is the middle layer of the earth. The Crust: It is the outermost layer of the earth.

The above-mentioned layers of the earth were formed with the impact of the building blocks of the earth that are remarkably known as Planetesimals, collided, and collapsed.

During that time, the hardest elements like nickel, iron, etc. constitute the core while the lighter elements like carbon, oxygen, silicon, etc. play an essential role in the formation of crust and mantle.

Therefore, the layers of the earth were formed due to the sediments that significantly flattens out beside the center of the earth.

What is the frequency of a photon with an energy of 3.38 x 10-19 J?​

Answers

Hey There!_____________________________________Answer:

[tex]\huge\boxed{5.1x[tex]10^{14}[/tex]Hz}[/tex]

_____________________________________DATA:

E = [tex]3.38 x 10^{-19}[/tex]

h = [tex]6.625x10^{-34}[/tex]

f = ?

_____________________________________SOLUTION:

Energy of Photon is given by,

                                   

                                   E = hf

Rearrange the equation,

                             

                                    f = [tex]\frac{E}{h}[/tex]

where,

           E = energy

           h = planck's constant

           f = frequency

------------------------------------------------------------------------------------------------------------

Substitute the variable in the equation,

 

                                 f = [tex]\frac{3.38x10^{-19}}{6.62x10^{-34}}[/tex]

Simplify the equation,

                               

                                  f = 5.10 x 10^14 Hz

what happens to the temperatures when we have direct sunlight vs indirect sunlight?

Answers

Explanation:

When we have direct sunlight, the temperature is higher compared to indirect sunlight.

Direct sunlight is usually overhead whereas indirect sunlight is at an angle to the surface.

Direct sunlight impacts the surface with more energy concentrated on a smaller surface area. This warms the surface more. Indirect sunlight is diffuse and spreads over a wider area. This leads to a reduction in temperature.

How would the calculated concentration of the hci be affected if the sodium hydroxide were poured from ma beaker that contained some water before the naoh were added to it

Answers

Answer:

This question is incomplete

Explanation:

This question is incomplete. However, the beaker that contained some water before NaOH were added means that the resulting solution in that beaker will be more dilute. When this diluted sodium hydroxide solution is added to HCl (not hci), the reaction below occurs

HCl + NaOH ⇒ NaCl + H₂O

The reaction above is a neutralization reaction. The concentration of the acid (HCl) will reduce when a base (sodium hydroxide) is added and will also reduce more because of the presence of more water (in the base) which normally reduces the concentration of ions present in an acid or a base to become more dilute.

What’s the answer????

Answers

Answer:

Greater

Greater

Explanation:

The amplitude of a wave is the height of the wave or the vertical displacement of the wave motion. We determine a wave amplitude usually by looking at the graph of the wave.

Amplitude is directly proportional to the energy of a wave. The higher the amplitude of a wave, the more its energy.

Frequency is the number of waves that passes a point at a particular instance of time. It is also directly proportional to the energy carried by a wave. The higher the frequency of a wave, the greater its energy.

Answer: its B. The average kinetic energy of the particles.

Don’t trust the person above

Explanation:

I took the quiz and i got it right

A Temperature is a unit used to represent hotness or coolness on any of a number of scales, including Fahrenheit and Celsius. The direction that heat energy will spontaneously flow depends on temperature. The average kinetic energy of the particles is indicated by temperature. The correct option is B.

Temperature and heat are connected but distinct concepts. The average kinetic energy of a substance's particles is measured by its temperature. The kinetic energy of an object increases with its temperature. A sort of energy connected to motion is called kinetic energy.

The average kinetic energy of the particles in a substance is measured by temperature. The overall kinetic energy of the particles in a substance is measured by its thermal energy. The temperature and thermal energy of a substance increase with particle mobility.

Thus the correct option is B.
