It is due to agitation of the heart. This is the result of a blow in the area directly over the heart.
<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.

Ok, so when a horse (with 64 chromosomes) is crossed with a donkey(that has 62 chromosomes), each parent give its child half of its chromosomes. [64/2=32] [62/2=31]. So the mule gets 31 pairs of chromosomes plus 32 pairs of chromosomes. That equals 63 total chromosomes. In order to be a parent, it must give <span>half of its chromosomes to its child. [63/2=31.5] You can't have half a chromosome, so the mule is a sterile organism. Let me know if you have questions.</span>
Answer:
Ribose
Explanation:
DNA is a large molecule, a type of nucleic acid which store and act as a genetic material of the cell. DNA molecule is formed by the repeating monomer units called nucleotides.
Each nucleotide is made up of three subunits as:
1. 5-C sugar: De-oxyribose formed by the removal of oxygen group from 2' OH group of ribose. Ribose is the sugar molecule present in RNA nucleic acid.
2. Phosphate group (PO₄³⁻)
3. Nitrogenous bases: adenine, guanine, adenine and cytosine.
Thus, ribose is the correct answer.
