Answer the following question given this paragraph: Annelids are divided into many repeating segments. The earthworm in Figure below is an annelid. You can clearly see its many segments. Segmentation of annelids is highly adaptive. Each segment has its own nerve and muscle tissues. This allows the animal to move very efficiently. Some segments can also be specialized to carry out particular functions. They may have special structures on them. For example, they might have tentacles for sensing or feeding, "paddles" for swimming, or suckers for clinging to surfaces. Q: What distinguishing characteristic of annelid anatomy shows specialization and adaptation? Choices: - asymmetry - beautiful - compression - segmentation A:
segmentation

Answer the following question given this paragraph: Binary compounds are compounds composed of just two elements. The simplest kind of decomposition reaction is when a binary compound decomposes into its elements. Mercury(II) oxide, a red solid, decomposes when heated to produce mercury and oxygen gas. Q: What are compounds composed of only two elements called? Choices: - digital compounds - symbiotic compounds - kinetic compounds - binary compounds A:
(A).
binary compounds
Ques:Answer the following question given this paragraph: Many enzymes are simple proteins consisting entirely of one or more amino acid chains. Other enzymes contain a nonprotein component called a cofactor that is necessary for the enzyme's proper functioning. There are two types of cofactors: inorganic ions [e. , zinc or Cu(I) ions] and organic molecules known as coenzymes. Most coenzymes are vitamins or are derived from vitamins. Q: Many enzymes are simple proteins consisting entirely of one or more of these? Choices: - alkali acid chains - interaction acid chains - proteins acid chains - amino acid chains A:

Ans:amino acid chains
