Answer the following question given this paragraph: Facial Bones of the Skull The facial bones of the skull form the upper and lower jaws, the nose, nasal cavity and nasal septum, and the orbit. The facial bones include 14 bones, with six paired bones and two unpaired bones. The paired bones are the maxilla, palatine, zygomatic, nasal, lacrimal, and inferior nasal conchae bones. The unpaired bones are the vomer and mandible bones. Although classified with the brain-case bones, the ethmoid bone also contributes to the nasal septum and the walls of the nasal cavity and orbit. Q: The paired bones of the skull are the palatine, zygomatic, nasal, lacrimal, inferior nasal conchae bones, and what else? Choices: - minilla - ventral - elongated - maxilla A:
maxilla

Answer the following question given this paragraph: The basic unit of matter is an atom ( Figure below ). At the center of an atom is its nucleus . Protons are positively charged particles in the nucleus. Also in the nucleus are neutrons with no electrical charge. Orbiting the nucleus are tiny electrons. Electrons are negatively charged. An atom with the same number of protons and electrons is electrically neutral. If the atom has more or less electrons to protons it is called an ion . An ion will have positive charge if it has more protons than electrons. It will have negative charge if it has more electrons than protons. Q: What is the basic unit of matter? Choices: - nucleus - dark material - neutron - atom A:
(Answer)
atom
Ques: Answer the following question given this paragraph: The rate of the expansion of the universe is increasing. The cause of this increase is unknown; one possible explanation involves a new form of energy called dark energy. Q: What is happening to the rate of the expansion of the universe? Choices: - it is decreasing - it is stable - it is unknown - it is increasing A:
Ans: it is increasing

Answer the following question given this paragraph: All chemical changes involve a transfer of energy. When zinc reacts with hydrochloric acid, the test tube becomes very warm as energy is released during the reaction. Some other reactions absorb energy. While energy changes are a potential sign of a chemical reaction, care must be taken to ensure that a chemical reaction is indeed taking place. Physical changes also involve a transfer of energy. Melting of a solid absorbs energy, while the condensation of a gas releases energy. The only way to be certain that a chemical reaction has taken place is to test the composition of the substances after the change has taken place to see if they are different from the starting substances. Q: All chemical changes involve a transfer of what? Choices: - hydrogen - pressure - nitrogen - energy A:
(A).
energy
Ques:Answer the following question given this paragraph: Each field of life science has its own specific body of knowledge and relevant theories. However, two theories are basic to all of the life sciences. They form the foundation of every life science field. They are the cell theory and the theory of evolution by natural selection. Both theories have been tested repeatedly. Both are supported by a great deal of evidence. Q: The cell theory and the theory of evolution by natural selection are basic to all fields in what branch of science? Choices: - rock science - zoology - chemistry - life science A:

Ans:life science
Answer the following question given this paragraph: When energy is released in a chemical reaction or process, that energy is expressed as a negative number. Figure below shows electron affinities in kJ/mol for the main group elements. Q: How is energy expressed when it is released in a chemical reaction? Choices: - as an equation - as a percentage - as a positive number - as negative number A:
as negative number
