Basically, there is a presentation of types of food and the amount of those foods over 50 years in this graph. This means the graph is showing amounts of certain foods over the time period. I'm guessing that basing off of the the previous text you're just noting a change in the breaks of birds based off of the diet available to them at certain times. The adaptations and natural selection will explain the changes because due to certain limited and available foods the diet of the birds change.
Answer:
Disease- and drought-resistant plants that require fewer environmental resources (such as water and fertilizer) Less use of pesticides. Increased supply of food with reduced cost and longer shelf life.
Scientists who do this are doing what is considered to be and called cloning. Cloning is exactly this - taking cells from one organism and trying to produce and recreate an identical (from a genetic perspective) organism.
This can be done in a routinely fashion but there are serious ethical considerations nowadays.
<span>B. Knowledge and valuable resources are shared among scientists.
Being involved in a research community could provide a higher chance to researchers the privilege to avail resources, knowledge and supporting evidences that might relate or support the current study the research wants to delve into.</span>
Answer: They may be wind blown, rain splashed, carried by animals, or moved in soil or water. Almost all short-distance spread is through these natural dispersal mechanisms. In their home territory, short distance spread is rarely a problem because the resident plants and animals have evolved to coexist more or less peaceably.
