The chemical formula of ammonium phosphate is (NH4)3PO4. There is 3*4=12 Hydrogen atom in one molecule ammonium phosphate. The total mass of one molecule is (14+4)*3+31+16*4=149. The mass of hydrogen atoms in one molecule is 3*4=12. So the mass percent of hydrogen is 12/149*100%=8.05%
Answer:
This structure has not been highly beneficial for the organism
Explanation:
Vestigial structures are cells, tissues, and/or organs that have no apparent function. Vestigial structures are retained during the course of the evolution, but often they are degenerate and/or atrophied (due to disuse). In general, these structures are homologous to anatomical structures that play a specific role in evolutionarily related species. Some examples of vestigial structures include, among others, the presence of the appendix in humans and wings in flightless birds.

Rotation is the spinning of a planet, revolution is when a planet circles the sun/planet.
Answer:
1) The protein is a tetramer, i.e., it has 4 subunits
2) The protein has two identical subunits with a molecular weight of 90 kDa
3) Because this protein contains two subunits with identical molecular weight (90 + 90= 180)
Explanation:
160 kDa + 90 kDa + 60 kDa = 310 kDa >>
Subunit X = 400 kDa - 310 kDa = 90 kDa >> Two subunits with a weight of 90 kDa likely linked by disulfide bonds (i.e., non-reducing conditions can break all bonds except sulfide interactions)
