Answer:
1) Pollen is released from the anther.
2) Pollen sticks to the stigma.
3) Pollen tube forms and grows through the style.
4) The pollen tube reaches the ovule within the ovary.
5) Sperm fertilizes the egg.
Explanation:
Pollination is a process in which pollen grains are transfer from anther to stigma of the flower. It occurs through wind, water and insect such as bees. When pollen gets mature, it falls from anther to the stigma. There it makes a tube which goes to the ovary. This pollen reaches the ovary through this tube and combines with ovule and fertilization occurs.

Answer:
Duration of the magnetic polarity event
Rate at which the plates are moving away from the mid-ocean ridge
Explanation:
The marine magnetic anomaly usually refers to the variation that occurs in terms of the magnetic field strength of the earth. This takes place because of the presence of minerals within the rocks of seafloor that contains high magnetic property.
These magnetic anomalies occurring in the marine rocks cover only about 1% of the total strength of the geomagnetic field. It shows either positive or negative anomaly.
Some of the factors that influence the width of this marine magnetic anomalies on the rocks of ocean-floor includes:
- The amount of time it takes during the magnetic polarity event
- The rate at which the tectonic plates move at a divergent plate boundary from the mid-oceanic ridge.
