The answer is <span>b.reaction b releases more energy than reaction a releases.

The reaction a is an example of a chemical reaction while the reaction b is an example of a nuclear reaction. 
</span><span>Some main differences between the chemical and nuclear reactions are:
- The nuclear reaction releases more energy per gram.
- The nuclear reaction takes place in the nucleus of the atom, while in chemical reactions include electrons.
- In the nuclear reaction, part of the mass is converted into energy, which </span><span>violates the law of conservation of mass.
</span>
Therefore, the nuclear reaction (reaction b) will release more energy than the chemical reaction (reaction a).

Write the procedure to observe human cheek cell​
scoundrel [369]

Answer:

To observe the cheek cell,

  • Take a tooth pick use its blunt side to scrap inside the mouth.
  • You will see some deposition on the blunt side of tooth pick, make a smear on the clean slide in the center using that tooth pick.
  • Add a drop of methylene blue solution and place a coverslip, make sure that bubbles are avoided i.e. coverslip should be placed in the inclined manner.  
  • Remove the excess solution and observe it under the microscope first under 4X and then under 10X.

Observation:  

  • The cells observed are squamous epithelial cells. The small blue dots seen inside will be the bacteria from our teeth and mouth.

What is the
lara31 [8.8K]

Answer:

Current Air Temperature

The current air temperature plotted to the nearest whole degree Fahrenheit.

Dew Point Temperature

The dew point temperature plotted to the nearest whole degree Fahrenheit.

Sky Cover

The total amount of clouds in tenth. Plotted in the station circle according the the following table.

Wind Speed And Direction

The wind direction is plotted as the shaft of an arrow extending from the station circle toward the direction from which the wind is blowing. The wind speed is plotted as feathers and half-feathers representing 10 and 5 knots, on the shaft on the wind direction arrow. See the following table.

Visibility

The visibility plotted in fractions of a mile. For values above 10 miles, the values are omitted from the map.

Sea Level Pressure

The barometric pressure in tenths of millibars reduced to sea level. The initial 9 or 10 and the decimal points are omitted.

ex: plotted = 982, actual = 998.2 mb

ex: plotted = 012, actual = 1001.2 mb

Pressure Tendency

The pressure change in the past 3 hours preceding the observation. Plotted to the nearest tenth of a millibar. The plotted symbol characterizes the change in pressure according to the below chart.

The human hands and feet have similar types and numbers of bones. However, hands and feet are very different in their appearance
Ira Lisetskai [31]

<u>Explanation:</u>

One physical difference between the hands and feet is that the human hands appear to be more flexible than our feet. Also, in terms of size, our feet are smaller than our hands.

Let's assume that our feet become as flexible as our hands and the hands less flexible, it would affect the function they perform.

  • If for example, we were to walk with our hands we will fail to achieve stability.
  • And if for example, we decide to grab hold of items with our feet we will be unable to do so.

It is also reasonable to expect other primates to have hands and feet that differed from ours because they are necessary so they can adapt to their environment just like humans too.
