<span>Unlike the methods of early scientists, Sir Francis Bacon believed basic laws of science should be determined by using inductive reasoning based on empirical evidence. You cannot formulate a law in science if you don't have evidence to support it - so you cannot just take a basic truth and formulate your law based on that - there has to be some kind of evidence to prove your theories. Also, based on those evidence, you will induce a conclusion necessary for such laws, which is something Bacon understood, unlike early scientists.</span>
<span>These
islands have different ecologies and most are not connected to each other by landmass.
Therefore, the organism adapt to each of the different ecologies on their
islands. These populations were physically separated due to lack of connection
to each other and would not breed randomly. They therefore formed different species
by allopatric speciation.</span>
Answer:
The correct option is d) head.
Explanation:
Bicoid protein works as a transcription factor. It enters the nuclei of the embryos in early segmentation, where it activates the hunchback gene. In Drosophila, embryonic development begins at the time of fertilization. The sperm enters the mature oocyte through the micropile, a structure located in what will be the anterior region of the egg. Bicoid and hunchback mRNAs, protein products are critical for the formation of the head and thorax. Already in the early stages of oocyte development, certain mRNAs are located in specific regions of the oocyte: mRNA molecules encoding the Bicoid protein are preferentially located in the anterior region of the oocyte. Moderate levels of the bicoid protein are necessary to activate the formation of the thorax (i.e., the expression of the hunchback gene) but the formation of the head requires high concentrations of Bicoid, the promoters of a specific gap gene of the head must have sites of low affinity binding for Bicoid, so that this gene can be activated only in extremely high concentrations of Bicoid.
The lack of Bicoid protein affects the formation of the head and other structures in the anterior region of the oocyte.
