Explanation:
They are called sacromeres.
There are several sources in which one may turn to in order to establish a well-founded idea, information, and knowledge towards a given topic. From this item, books were collectively identified as the first source for Jamal's science essay.
The second one could be the information found in the internet. These information have lately became very accessible considering that one could directly upload/download information. The tricky part here is to identify which sources in the internet are reliable and which are not.
Answer:
question 1 : all answers are true
question 2 : the ability to do work
Answer:
a) Some island populations will have fixed one allele, and other populations will have fixed the other allele.
Explanation:
The founder population for each island is heterozygous for the locus. The absence of any migration and mutation would result in no gene flow or the introduction of new alleles of the locus. Over several generations, one or the other allele will be fixed in the populations depending on the adaptive features imparted by each under the different conditions present on these different islands. Genetic drift may also work on these small founder populations to randomly fix one or the other allele.
