All mammals are vertabrates, because they are in the phylum chordata, meaning that all of the animals there have vertebrae. In fact, all mammals have exactly 7 neck vertebrae, no matter how long their neck is.
It seems that you have missed the necessary options for us to answer this question, so I had to look for it and here is the answer. When a researcher discovers a small molecule in muscle tissue that is rich in nitrogen, soluble in water, and lacks phosphorus, the <span> molecule also contains carbon, hydrogen, and oxygen, in uneven ratios. The molecule must be an AMINO ACID. Hope this helps. </span>
Answer:
2. macroevolution
Explanation:
Macroevolution refers to the evolutionary processes that lead to the appearance/extinction of groups larger than individual species. Macroevolutionary processes include speciation, species selection and punctuated equilibrium. The punctuated equilibrium processes are represented by phenomena such as those cases described above. These evolutionary processes are concentrated in relatively short speciation phases caused by bursts of evolutionary changes, which are then followed by stages characterized by evolutionary stasis.
Your answer should be A. 20%

Answer:
D.
Explanation:
Natural selection is the way that organisms adapt through adaptations to better survive and pass on the special genes which enable the offspring to survive. Saying an organism will always mutate to survive is wrong, as natural selection implies that not all organisms survive. With natural selection, nothing is "selected", so B and C are not correct. However, mutations DO make organisms "more fit" to survive their environments, so D is the answer.
