asexual
(Question)
Answer the following question given this paragraph: An internal skeleton. The internal skeleton supports the animal, protects internal organs, and allows for movement. Q: Which type of skeleton supports the animal, protects internal organs, and allows for movement? Choices: - external - mechanical - shell - internal A:
(Answer)
internal
Ques: Answer the following question given this paragraph: Keeping the rate of metabolism high takes a constant and plentiful supply of oxygen. That's because cellular respiration, which produces energy, requires oxygen. The lungs and heart of mammals are adapted to meet their oxygen needs. Q: A constant and plentiful supply of oxygen is required in order to maintain a high rate of what? Choices: - digestion - cell division - magnesium - metabolism A:
Ans: metabolism
(Q).
Answer the following question given this paragraph: DNA and RNA are nucleic acids. DNA stores genetic information. RNA helps build proteins. Proteins, in turn, determine the structure and function of all your cells. Proteins consist of chains of amino acids. A protein's structure and function depends on the sequence of its amino acids. Instructions for this sequence are encoded in DNA. Q: Both dna and rna are what type of acids? Choices: - proteins acids - synthesize acids - fatty acids - nucleic acids A:
(A).
nucleic acids
Ques:Answer the following question given this paragraph: 2.2 Chemical Bonds Each moment of life, atoms of oxygen, carbon, hydrogen, and the other elements of the human body are making and breaking chemical bonds. Ions are charged atoms that form when an atom donates or accepts one or more negatively charged electrons. Cations (ions with a positive charge) are attracted to anions (ions with a negative charge). This attraction is called an ionic bond. In covalent bonds, the participating atoms do not lose or gain electrons, but rather share them. Molecules with nonpolar covalent bonds are electrically balanced, and have a linear three-dimensional shape. Molecules with polar covalent bonds have "poles"regions of weakly positive and negative chargeand have a triangular three-dimensional shape. An atom of oxygen and two atoms of hydrogen form water molecules by means of polar covalent bonds. Hydrogen bonds link hydrogen atoms already participating in polar covalent bonds to anions or electronegative regions of other polar molecules. Hydrogen bonds link water molecules, resulting in the properties of water that are important to living things. Q: Cations are attracted to anions, which are ions with what charge? Choices: - similar - neutral - positive - negative A:

Ans:negative
Ques:Answer the following question given this paragraph: The human body is organized at different levels, starting with the cell. Cells are organized into tissues, and tissues form organs. Organs are organized into organ systems such as the skeletal and muscular systems. Q: What structure of the body falls between cells and organs in complexity? Choices: - muscles - molecules - proteins - tissues A:

Ans:
tissues
