Ques:Answer the following question given this paragraph: Recall that terrestrial biomes are defined by their climate. That's because plants and animals are adapted for certain amounts of temperature and moisture. However, would aquatic biomes be classified in the same way? No, that wouldn't make much senseall parts of an aquatic environment have plenty of water. Aquatic biomes can be generally classified based on the amount of salt in the water. Freshwater biomes have less than 1% salt and are typical of ponds and lakes, streams and rivers, and wetlands. Marine biomes have more salt and are characteristic of the oceans, coral reefs, and estuaries. Q: How are aquatic biomes often classified? Choices: - depth - amount of life - amount of light - amount of salt A:

Ans:amount of salt

Ques:Answer the following question given this paragraph: When amino acids bind together, they form a long chain called a polypeptide . A protein consists of one or more polypeptide chains. A protein may have up to four levels of structure. The lowest level, a protein's primary structure, is its sequence of amino acids. Higher levels of protein structure are described in Figure below . The complex structures of different proteins give them unique properties, which they need to carry out their various jobs in living organisms. You can learn more about protein structure by watching the animation at the following link: http://www. stolaf. edu/people/giannini/flashanimat/proteins/protein%20structure. swf . Q: When amino acids bind together, they form a long chain called what, which is an essential component of protein? Choices: - peptide - lipids - enzyme - polypeptide A:

Ans:polypeptide

Ques:Answer the following question given this paragraph: The most basic division of living plants is between nonvascular and vascular plants. Vascular plants are further divided into seedless and seed plants. Seed plants called gymnosperms produce seeds in cones. Seed plants called angiosperms produce seeds in the ovaries of flowers. Q: What are the two divisions of vascular plants? Choices: - root and seed - seedless and semi-seeded - aquatic and terrestrial - seedless and seed A:

Ans:seedless and seed

Ques:Answer the following question given this paragraph: Toward the late stages of pregnancy, a drop in progesterone and stretching forces from the fetus lead to increasing uterine irritability and prompt labor. Contractions serve to dilate the cervix and expel the newborn. Delivery of the placenta and associated fetal membranes follows. Q: Toward the late stages of pregnancy, a drop in progesterone and stretching forces from the fetus lead to increasing uterine irritability and prompt labor. contractions serve to dilate the cervix and expel this? Choices: - blood - tissues - uteris - newborn A:
