Answer:
IB IB and IB i is the pair of genotypes that results in the same phenotype. genotypes means the genetic constitution of an individual organism. And phenotype is the set of observable characteristics of an individual resulting from the interaction of its genotype with the environment.
Explanation:
The scientist should compare the anatomies of the fossil and present day dragon fly to determine the relation between the two.
Explanation:
- Diet is a common factor between many species,i.e. Different animals can have same died for example there are several grass eating species so this will not establish a close relation between the two.
- A single habitat can be occupied by different species , for example a grassland can be the habitat of lion, zebra , various insects etc. Secondly, getting a clear idea about the habitat of a fossil specimen is difficult and can be hypothetical. Thus, this is not a criteria to be compared.
- Different animal can have same predator, for example, a zebra, a deer and a nil gai have lion as the predator. Again determine the predator of a fossil specimen is very difficult and might lead to a hypothetical conclusion. Thus predators are also not factors of comparison here.
- The Anatomy of an organism is quite similar to its ancestor, the structural plan of the body can easily be compared. For example the anatomical features of man and apes are closely established. Thus, Comparing the anatomy will determine the closeness of the give species.
Answer:
A silent mutation is a change in the sequence of nucleotide bases which constitutes DNA, without a subsequent change in the amino acid or the function of the overall protein. A silent mutation is just that: it does nothing significant, not making a sound in the orchestra of the cell
Explanation:
Answer:Plate tectonics explains why Earth's continents are moving; the theory of continental drift did not provide an explanation. Therefore, the theory of plate tectonics is more complete. It has gained widespread acceptance among scientists
Explanation:
Given what we know, we can confirm that despite the students having the same 5 nitrogen bases, all the DNA models created will not be equal.
<h3>What makes these models different?</h3>
- The models will differ due to DNA sequence.
- What this means is that the order in which the base pairs are aligned affects the outcome.
- There are well over 20+ different ways in which to arrange four nitrogen pairs to create a DNA model.
- The fifth nitrogen base adds even more possibilities.
Therefore, just as with the genetic code in all living organisms, it is made of 4 nitrogen bases. What makes the DNA of each organism distinct is the ordering and sequence of these nitrogen bases within our DNA.
