Answer:
B. mutations
Explanation
I believe this is the answer because even though mutations can be bad, there are also good as they can provide genetic variation to a population, which can result in the trait being passed to the offspring.

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.
The appropriate response is the Olfactory Bulb. It is a mind structure in charge of our feeling of smell. Situated at the tip of the olfactory projection, the knob forms data about smells in the wake of getting tangible contribution from the nose.
The olfactory bulb is a heap of afferent nerve strands from the mitral and tufted cells of the olfactory globule that interfaces with a few target areas in the mind, including the piriform cortex, amygdala, and entorhinal cortex.
