MRNA is a short lived form of genetic information that is used in transcribing the genetic information, hence it is not very useful for analysis since it is fragile and wrong transcriptions happen quite often. SNPs (Single Nucleotide Polymorphisms) are a form of genetic mutation; they are more frequent than most other mutations since a single transription error may lead to this. While SNPs are important in genetic analysis and getting information about causes of disease, they are not very helpful in determining your maternal lineage. Similarly, while nuclear DNA contains a large portion of our genetic information, half of it is from our fathers and half from our mothers, so the analysis becomes hazy very soon. Mitochondrial DNA instead is directly passed down from mother to her offspring since the embryo contains only the mitochondria of the ovary. Thus, studying differences between mitochondrial DNA, one can gain information about his maternal lineage and go back to Mitochondrial Eve, the person from which all living persons have gotten their mitochondria from. Thus, the correct answer is c.
The answer is B) Most sources of data about hurricanes are anecdotal & unreliable.
Answer:
A. the daisy is an autotroph
Explanation:
autotrophs get their food from the sun
The preferred prey item would be frogs.
What is optimal foraging theory?
It is a theory in ecology that proposes that predating animals that get the most energy from minimal efforts are favored by natural selection.
In order words, selection forces prefer investing minimum energy in order to extract maximally available energy.
In this case, the heron needs to use the lowest time to harvest the maximum energy possible. Since all the preys offer the same amount of energy, the one that requires the lowest time would be preferable for the heron.
In other words, frogs would be the most preferable prey.
