Meiosis creates gametes (eggs and sperm) with only a single chromosome set (haploid or n) from parental cells with two chromosome sets (diploid or 2n). During fertilization, the haploid sperm (n) and egg (n) fuse, producing a diploid zygote (2n). The cells of the zygote then divide by mitosis (which does not change the ploidy level) to produce an adult organism (still 2n) of the next generation.
<span>In sexual life cycles, meiosis and fertilization keep the number of chromosomes constant from generation to generation. </span>
I believe they are both equally friendly. It all depends on size in my opinion. My friend owns a Shar Pei and it's his best friend.
I'm not sure what YOU already know about photosynthesis and cellular respiration.... however, you SHOULD know that the two are beautifully linked to one another!
Photosynthesis equation:
6CO2+6H2O -> C6H12O6+H2O
Cellular respiration
C6H12O6+H2O -> 6CO2+6H2O
Notice something? The substrates of one equation are the products of the other! We rely on plants for their photosynthetic reactions - and plants benefit from us (not really because there is already a TON of CO2 in the atmosphere) from our cellular respiration
***we like their oxygen and they like our carbon dioxide!
:) I hope that helps! Let me know if you need any more elaboration!
Fault-block mountains form when Earth's crust pushes material up and down near a fault line.<span> Rocks that get pushed upward eventually form mountains if there is enough seismic activity. The higher part of a fault-block area is called a horst, while the lower part is called a graben, according to Ducksters.

The carbon cycle moves through virtually all of the earth's spheres.
<h3>Carbon cycle</h3>
There are 4 majors spheres of the earth:
- Atmosphere
- Geosphere or Lithosphere
- Biosphere
- Hydrosphere
The carbon cycle moves through the air (atmosphere), oceans (hydrosphere), organisms (biosphere), and the soil (geosphere).
Thus, the carbon cycle moves through all the spheres of the earth.
