If the food type changes in a given environment, then the amount of each type of bird beak will change as birds with beaks more suited to the available food will consume more successfully over time. <span>The independent variable of the lab is the type of food that is available to the birds. The dependent variable of the lab is the frequency of each type-size and shape-of beaks. The conclusion will state that favourable traits place one species in a more optimal position to survive in a given envronment.</span>
The correct answer is (a.) True. The Large variation in a crop may be developed by employing asexual reproduction. Asexual reproduction is a type of reproduction in which the offspring came from a single organism and may inherit only the parent's gene, not fusion of gametes.
The answer is population density
Answer:
True-breeding plants.
Explanation:
The self pollination in plants that produces progeny with similar characteristics or traits is called True-breeding plant. The parent and progeny both are identical genetically in true-breeding plants. The alleles shared between both offspring and parental plant is also same. The homozygous alleles are present in such organisms. The presence of homozygous alleles mean both alleles are same thus resulting in similar characters. Thus, plants that if left to self pollinate produce offspring identical to themselves are called True-breeding plants.
The biodiversity on Earth indicates that the organisms cannot tolerate extreme environments. Therefore, D. is the correct answer.
