Darwin concluded that the finches all shared a common ancestor but had  developed different beak structures.  The second sentence best describes as an ecosystem.

Explanation:

  • When Charles Darwin traveled to the Galapagos Islands, he observed 14 distinct varieties of finches on the islands Darwin also observed that each finch variety  ate a different type of food and lived in a slightly different habitat from the other finches, Darwin concluded that the finches all shared a common ancestor but had  developed different beak structures. The second sentence best describes as an ecosystem.
  • An ecosystem is a huge group of living organism such as plants,animals, micro-organisms in a particular area.
  • An ecosystem is a community of living organisms related with the nonliving components in the  environment, together interacting as a system.
  • its abiotic constituents, includes minerals, climate, soil, water, sunlight, and all other nonliving elements, and its biotic constituents, consists of all its living members.

Choose the correct statements 1.Self-pollination occurs when the pollen from the anther is deposited on the stigma of the same f
Mamont248 [21]

Answer: The correct statements are 1 and 2:

1.Self-pollination occurs when the pollen from the anther is deposited on the stigma of the same flower, or another flower on the same plant.

2.Cross-pollination is the transfer of pollen from the anther of one flower to the stigma of another flower on a different individual of the same species.

Explanation:

Pollination is the transfer of pollen grains from an anthers to a receptive stigma. In most species of flowering plants, external agents bring about pollination. Also, flowers have evolved special structures and mechanisms to ensure successful pollination.

There are two types of pollination

--> Self pollination: This takes place when mature pollen grains from the anther of a flower fall on the stigma of the same flower or that of another flower on the same plant. This type of pollination brings the male gametes and egg cells of the same plant together. The resultant offspring show very little genetic variation.

--> Cross pollination: This occurs when mature pollen grains of a flower are transferred to the stigma of a flower of another plant of the same or closely related species. This brings the male gametes and egg cells of two different parent plants together. Therefore, there is greater genetic variation among the offspring.
