The Moon is the only natural satellite of the Earth. With an equatorial diameter of 3476 km, it is the fifth largest satellite in the solar system, while in terms of proportional size with respect to its planet it is the largest satellite: a quarter of the diameter of the Earth and 1/81 of its mass. I hope I have helped you and if you do not forgive
Genetic material composed of DNA
true helpful answer to your question
Answer:
knirps (a gap gene)
wingless (a segment-polarity gene)
kruppel (a gap gene)
even-skipped ( a pair-rule gene)
hunchback (a gap gene)
hedgehog (a segment-polarity gene)
Explanation:
The gap, segment-polarity and pair-rule genes play central roles in controlling embryonic development of arthropods. In the first place, the gap genes are associated with the formation of contiguous body segments, thereby mutations in these genes result in gaps in the normal body plan of the embryo. For example, in <em>Drosophila melanogaster</em>, mutations in the <em>knirps, Krüppel </em>and<em> hunchback</em> genes result in deletion of body segments. These genes are also known to regulate segment polarity genes, which determine the polarity of the embryonic parasegments by modulating Wnt and Hedgehog signaling pathways. Finally, the pair-rule genes work together with gap genes to control embryonic development of alternating body segments.
Well in an environment when the environment changes so do all the organisms in it. Little of small all changes in the environment can have a huge effect in the life around it. When the environment changes all the organisms around it may change to better suit themselves into it to better survive. The changes the organisms go through could be small such as moving where they live in that environment, or large like adapting to the new colors around them by over a specific amount of time they adapt to match these colors, by breeding and evolution.
