Answer:

The correct answer will be options-

1. transported by blood

2. picked up in the alveoli

3. pumped to cells by ventricles

Explanation:

Oxygen is an important element on earth on which life is dependent as it is the substrate of the important metabolic process of life.

The Oxygen in humans is inhaled and exhaled by breathing which when inhaled gets picked up or exchanged with the connective tissue of the body called blood in the alveoli of the lungs.

The oxygen in the blood is pumped to the body cells by the left ventricle of the heart which along with blood transports the oxygen by binding to haemoglobin in red blood cells.

Thus, the selected option is the correct answer.

How fast should a moving clock travel if it is to be observed by a stationary observer as running at one-half its normal rate?A)
Elan Coil [88]

Answer:

Option (D) is correct.

Explanation:

Let the speed is v.

\Delta t = \gamma \Delta t'\\\\\Delta t = \frac{1}{\sqrt{1-\frac{v^2}{c^2}}}\times \frac{\Delta t}{2}\\\\\sqrt{1-\frac{v^2}{c^2}} =\frac{1}{2}\\\\1-\frac{v^2}{c^2}=\frac{1}{4}\\\\\frac{3}{4}c^2 = v^2\\\\v = 0.87 c

Option (D) is correct.

1.Why is it important to accurately predict possible formation and path of a hurricane?
stellarik [79]

1. By predicting the path of hurricanes, it is possible to warn people in its prospective path in advance. This way lives can be saved. In addition economic cost. associated with its destruction, can be minimized by bracing in advance for the storm along its path.


2. When the sea temperatures increase, there is increased vaporization of water into the atmosphere. This causes a transfer of heat into the atmosphere from the hydrosphere. This causes a drop of pressure in the local region that is one ingredient  associated with the beginning of a hurricane.


3. The more the humidity, it means the more the heat transfer to the atmosphere through condensation. This reduces the pressure proportionally with the amount of humidity. This low pressure is an ingredient for hurricanes. In addition, the higher the humidity the larger the clouds and the larger the thunderstorms and precipitation associated with the hurricane


4. Winds drive hurricanes and determines their vicious force. In the formation of the hurricane, low winds are required to allow the formation of the funnel at the front betwen the cold and warm air masses. Winds blowing in congruence with the hurricane after then make it stronger while those that blow against it weaken it.


5. The answer is; YES, I would expect a hurricane. This is because at 12 0 N and 45 0 W are the open oceans of the Pacific. The average sea temperaturs in summer is between 15 0 and 20 0. At 27.5 0, this increases the humidity at the local region and therefore the tranfer of heat to the atmsphere. The light breeze gives the stability required for the air convection currents to occur forming a funnel front between the air masses.

When does PE equal KE?
dybincka [34]
PE equals KE when KE is 50%. 

Like below:

E = PE + KE 
E = 50 + 50 
E = 100.

Remember, both KE and PE always have to add up to 100 so that is why PE is equal to KE when KE is 50% of energy. 

Hope I helped. :)
