Answer the following question given this paragraph: We can also consider the reverse reaction in the above equation. In that reaction, the ammonium ion donates a proton to the hydroxide ion. The ammonium ion is a Brnsted-Lowry acid, while the hydroxide ion is a Brnsted-Lowry base. Most Brnsted-Lowry acid-base reactions can be analyzed in this way. There is one acid and one base as reactants, and one acid and one base as products. Q: The ammonium ion is what type of acid? Choices: - normal -lowry - kaon - lowry - oxidized - lowry - brnsted-lowry A:
brnsted-lowry

(Answer)
force
Ques: Answer the following question given this paragraph: Water works its way through porous rocks or soil. Sometimes this water is heated by nearby magma. If the water makes its way to the surface, it forms a hot spring or a geyser. Q: When water is heated by magma and makes it's way to the surface what is created? Choices: - eruption - volcanic - trough - geyser A:
Ans: geyser

Answer the following question given this paragraph: Cnidarians are invertebrates such as jellyfish and corals. They belong to the phylum Cnidaria. All cnidarians are aquatic. Most of them live in the ocean. Cnidarians are a little more complex than sponges. They have radial symmetry and tissues. There are more than 10,000 cnidarian species. They are very diverse, as shown in Figure below . Q: Where do most cnidarians live? Choices: - grass - hills - rocks - ocean A:
(A).
ocean
Ques:Answer the following question given this paragraph: Living things need energy to carry out all life processes. They get energy from food. Q: Where do living things obtain the energy to carry out all life processes? Choices: - fuel - waste - oxygen - food A:

Ans:food
Answer the following question given this paragraph: DNA Repair DNA polymerase can make mistakes while adding nucleotides. It edits the DNA by proofreading every newly added base. Incorrect bases are removed and replaced by the correct base, and then polymerization continues (Figure 9.13a). Most mistakes are corrected during replication, although when this does not happen, the mismatch repair mechanism is employed. Mismatch repair enzymes recognize the wrongly incorporated base and excise it from the DNA, replacing it with the correct base (Figure 9.13b). In yet another type of repair, nucleotide excision repair, the DNA double strand is unwound and separated, the incorrect bases are removed along with a few bases on the 5' and 3' end, and these are replaced by copying the template with the help of DNA polymerase (Figure 9.13c). Nucleotide excision repair is particularly important in correcting thymine dimers, which are primarily caused by ultraviolet light. In a thymine dimer, two thymine nucleotides adjacent to each other on one strand are covalently bonded to each other rather than their complementary bases. If the dimer is not removed and repaired it will lead to a mutation. Individuals with flaws in their nucleotide excision repair genes show extreme sensitivity to sunlight and develop skin cancers early in life. Q: If a mistake is made by dna polymerase while adding nucleotides, incorrect bases are removed and replaced by the correct base, and the process of what continues? Choices: - fermentation - hybridization - digestion - polymerization A:
polymerization
