Answer:
Option (A).
Explanation:
Evolution may be defined as the change in the characteristics of a species over several generation with time. Natural selection acts as a main drivinf force for the evolution.
The drought of 1977 is responsible for the species evolution. The species is larger in this case (as mentioned in the question) and the species has deeper beaks over time. The birds have relatively large and deep beaks because they can easily crack the food.
Thus, the correct answer is option (A).
Plant obtain energy through photosynthesis .They are producers because they are able to obtain synthesize their food . Animals on the other hand are consumers and must obtain their energy by consuming organic matter such as plants and animals .
Pathology is the study of the cause and effect of diseases and sicknesses.
I would say D, as to observe the way that bipolar patients behave.
The amplitude measures the amount of displacement in a longitudinal wave.
Answer:
3.5 percent (3.5%)
Explanation:
In genetics, <em>crossing over</em> or 'recombination' refers to the exchange of genetic material between non-sister chromatids of homologous chromosomes during meiosis I. The map units (m.u.), also known as centimorgans, represent a measure of genetic linkage between genes/<em>loci</em> located on the same chromosome. One map unit (1 m.u.) is equal to a 1 percent chance that two gene/<em>loci</em> (in this case, genes H and K) will be separated during meiosis by recombination. In the example above, it means that among their progeny, 3.5 percent (3.5%) will be recombinant for the two genes (H and K), and 96.5 percent (96.5%) will have the parental combination of these genes.
