Suppose that an automated, unmanned probe is sent into deep space to search for extraterrestrial life. after wandering for many light-years among the far reaches of the universe, this probe arrives on a distant planet and detects life. the chemical composition of life on this planet is completely different from that of life on earth, and its genetic material is not composed of nucleic acids. what predictions can you make about the chemical properties of the genetic material on this planet?

For each of the following, decide whether the statement describes photosynthesis, cellular respiration, or both. releases energy in the form of atp. stores energy in glucose molecules. performed by producers. performed by consumers.

Aprocedure done under controlled conditions to test a hypothesis is an inquiry.

Astudy by solloch and et. al., in 2017, gives the map above which shows the frequency of alleles with a ccr5-delta32 mutations over 87 different countries. this mutation deletes the presence of a co-receptor (ccr5) on the outside of human t-cells (lymphocytes). some viruses, such as the one responsible for the black death and human immunodeficiency virus (hiv), require this receptor for attachment to host cells during the infection process. the black death was an epidemic that passed over northern europe during the 14th century killing nearly 60% of europeans. according to this information, which explanation best explains why northern europeans show a greater immunity for hiv than some other parts of the world?
