Define adaptation and give an example.

Definition:

Adaptation is the physical or behavioral characteristic of an organism that helps an organism to survive better in the surrounding environment.

Example:

A camel has many adaptions to help it survive in the desert. They can drink 20 liters of water in just a few minutes and store all of it in their stomach. They also produce very little urine. They have long eyelashes to protect from blowing sand and the sun. Their nostrils can also be closed to keep out dust.

both male and female gametes are produced by meiosis of the germ cells. therefore, both male and female gametes are haploid. one male and one female gamete unite during the fertilization to form the diploid zygote. in seed bearing plants, pollen grain is the male gametophyte, which produces sperm cells.

the water is warmed up by the sun and then it evaporates into the atmosphere. the sunlight warms the water by its heat. water is then cooled down and condensation takes place. the water then finally returns back to the earth by the process of precipitation in the form of rain or ice.
