<em>The correct option is B) A rat scurries past, and a python strikes at it.</em>
Explanation:
A stimulus can be described as any thing or event which is detected as a signal and a response is generated by the body of the organism for that signal. In the scenario discussed in option B)The passing of the rat acts as a signal for the python. In response to the signal, the python generates a response by striking the rat. Hence, it is an example of a stimulus and the accompanying response of an organism.

Answer:
Photosynthetic lamellae
Explanation:
The cyanobacteria were the first successful photosynthetic cells present on the Earth which were able to convert the light energy into the chemical energy.
The endosymbiosis theory suggested that these cyanobacteria were engulfed by the eukaryotes and the cyanobacteria get transformed into the chloroplast.
The region of the chloroplast that was formed in the cyanobacteria before the endosymbiosis happened was the photosynthetic lamellae which contained the chlorophyll molecule and thus is the correct answer.
Thus, Photosynthetic lamellae are the correct answer.
Answer: A physical change
Explanation: since the melted they are still Crayons. You can freeze it and it would still be a crayon. So it was only a physical change
