The answer is all of the above
Answer:
Rate of change of volume of the pile 
Explanation:
Given -
Rate of increase of the base of the pile 
inches per minute
Height of the pile 
the radius of the base
Let "h" be the height of the pile and "r" be the radius of the base.
Then 
Radius "r" 
inches
Rate of change of radius i.e
Volume of conical pile
Change in volume of conical pile
Substituting the value of rate of change of radius, we get -
Rate of change of volume of the pile
Answer:
Life cycle of a moss
Explanation:
LIFE CYCLE OF A MOSS FROM MATURED SPOROPHYTE STAGE
An embryo further develops into a pear-shaped sporangium, which is the *sporophyte stage of the plant*. The sporangium contains spore sacs, each of which is the spore mother cell that undergoes meiotic division to form four spores,The spores are released and germination
takes place giving rise to a protonema, which develops into a new gametophyte plant. The gametophyte generation or haploid phase of the moss is from the production of haploid spores after meiosis to the period just before fusion of the haploid antherizoid or haploid ovum. The sporophyte generation or diploid phase is from the diploid mother cells just before meiosis.
Examples of moss plants include Funaria hygrometrica, Polytrichum commune, Barbuda Indica.
Answer:
Pollination
Explanation: If you have ever seen bee movie, you know that pollen is the most essential ingredient to flowers, which is transported and spread by bee's. if there were no more bees, there would be no way to pollinate the flowers, causing them to wither and die. Fortunately, there are other pollinators, but bees are one of the most important.
Answer:
A comet is an icy, small Solar System body that, when passing close to the Sun, warms and begins to release gases, a process called outgassing. This produces a visible atmosphere or coma, and sometimes also a tail.
Explanation:
 a celestial object consisting of a nucleus of ice and dust and, when near the sun, a ‘tail’ of gas and dust particles pointing away from the sun.
