The evidence that the base pairs in the helical form of the DNA molecule are composed of one purine and one pyrimidine comes from  Chargaff's rule, X-ray diffraction studies, Watson and Crick's model.

The main pieces of evidence are as follows:

1. Chargaff's rule: Erwin Chargaff discovered that in DNA, the number of adenine (A) bases always equals the number of thymine (T) bases, and the number of guanine (G) bases always equals the number of cytosine (C) bases. This implies that A and T, as well as G and C, are complementary base pairs.

2. X-ray diffraction studies: Rosalind Franklin and Maurice Wilkins used X-ray crystallography to study the structure of DNA. Their images showed that DNA had a helical shape and a repeating pattern of 10 base pairs per turn. This pattern suggested that A and T (or G and C) were paired together.

3. Watson and Crick's model: James Watson and Francis Crick used all of the available evidence to build a model of DNA that explained its structure and how it replicated. They proposed that A and T formed two hydrogen bonds with each other, while G and C formed three hydrogen bonds. This explained why A-T and G-C pairs had the same width, and also suggested that the number of hydrogen bonds could be used to predict the strength of a base pair.

In conclusion, the evidence for the helical form of DNA molecule's base pairs being composed of one purine and one pyrimidine includes Chargaff's rule, X-ray diffraction studies, and Watson and Crick's model.

The yearly percent change in the number of deer is 40%.

The yearly percent change in the number of deer can be determined by calculating the difference in the number of deer between two consecutive years and expressing it as a percentage of the previous year's count. In the given function f(t) = 16(1.4), the coefficient of growth is 1.4, which represents the factor by which the number of deer increases each year.

To calculate the yearly percent change, we subtract 1 from the coefficient of growth to obtain 0.4. We then multiply this value by 100 to express it as a percentage. Therefore, the yearly percent change in the number of deer is 40%.

This means that the population of deer in the forest is increasing by 40% each year. For example, if there are initially 16 deer in the forest, after one year, the population would increase to 16 + (0.4 × 16) = 22.4 deer, which is approximately 22 deer when rounded to the nearest whole number. This growth rate continues each year, resulting in an exponential increase in the number of deer over time.

The rate of synonymous substitutions in a gene serves as an estimate of neutral evolution by genetic drift.

Synonymous substitutions refer to nucleotide changes in a gene that do not result in an amino acid change in the corresponding protein sequence. These substitutions are often considered neutral because they do not alter the function or structure of the protein.

The rate of synonymous substitutions can provide insights into the evolutionary dynamics of a gene. In particular, it can help estimate the rate at which genetic variations accumulate in a population due to random genetic drift, which is the change in gene frequencies over time due to chance events rather than natural selection.

Neutral evolution by genetic drift occurs when genetic variations become fixed or lost in a population purely by chance, without any selective advantage or disadvantage. The rate of synonymous substitutions reflects this neutral process, as it measures the accumulation of neutral genetic variations over time.

In contrast, gene flow between populations, evolution by natural selection, and coalescence are not directly estimated by the rate of synonymous substitutions.

Gene flow involves the exchange of genetic material between populations, natural selection involves the differential survival and reproduction of individuals based on their traits, and coalescence refers to the process of tracing the ancestry of genetic variation back to a common ancestor.
