Cross-pollination, or when pollen from one plant fertilizes another plant of the same produces outcrossing or outbreeding.
Explanation:
Cross pollination is the transfer of pollen from a plant's stamen to a different plant's stigma of the same species. They produces stronger plants. For example only pollen from a daisy can pollinate another daisy.
They have male and female reproductive units on separate plant. If they are on the same plant he pollen will not fertilize the female reproductive unit on the plant.
This process needs four steps pollination, germination, penetration of the ovule and fertilization. The Zygote divides to form an embryo after fertilization.
Considering that this bird most likely is going to compete for food with the large tree finch possible examples are woodpecker finch because they use the same food resources and small tree finch because they eat mainly animal food.
Answer:
Ammonification is crucial for providing living organisms with the essential nitrogen that they need.
Answer: microscopes
Similarly the development of microscopes drove, somewhat later in the same century, the discovery of cells; Hooke and van Leuwenhoek, like Galileo, were hands-on developers of their instruments.The discovery of the green fluorescent protein (GFP), increasingly sophisticated microscopes, and the development of in vitro assays that faithfully reproduce cellular functions are just a few examples of technical advances that have spurred on many areas of cell biology
