Once you have stopped for a school bus, do not pass until the driver signals you to proceed, the red lights stop flashing, or the bus starts moving ahead. Whenever a vehicle ahead of you stops to let a pedestrian pass in front of you, you should stay in line and until the vehicle ahead proceeds.
Answer:
The correct answer is - phase 2.
Explanation:
Erythropoiesis or the development of the erythrocytes is the process to which the development of the erythrocyte cells from the bone marrow to the mature RBC. The development of these cells involved the three phases.
During second phase involves the differentiation of the precursors of the three different type of erythrocytes that are polychromatophilic, proerythroblasts, and orthochromatic erythroblasts. It also includes building up the color of the hemoglobin that overwhelms the color of ribosomes that is blue color.
Thus, the correct answer is - phase 2.

<u>Answer:</u>
<em>Land and sea breeze are produced because the land changes temperature rapidly than the ocean.
</em>
<u>Explanation:</u>
<em>The rates of heating up of land and sea are different. Land gets heated up faster than water. Temperature is crucial in determining the density of air.
</em>
When land gets heated up the air near the land turns hot and this temperature is greater than the temperature of the air near the water surface. <em>Hotter air has less density than the air which is relatively less warm. Density difference creates pressure difference.
</em>
Denser air has higher pressure than less dense air making air move from area of high pressure to area of low pressure. During the day<em> the land is heated up more and thus air move from sea to land and it is called sea breeze. </em>Just like it absorbs heat land releases heat at a faster rate.
<em>Thus at night land the sea will be warmer than the sea and thus air will move from the land to the sea and it is called land breeze.
