Answer the following question given this paragraph: Water is an essential part of most metabolic processes within organisms. Metabolism is the sum total of all body reactions, including those that build up molecules ( anabolic reactions ) and those that break down molecules ( catabolic reactions ). In anabolic reactions, water is generally removed from small molecules in order to make larger molecules. In catabolic reactions, water is used to break bonds in larger molecules in order to make smaller molecules. Q: What is the sum total of all body reactions? Choices: - respiration - growth - immunity - metabolism A:
(Answer)
metabolism
Ques: Answer the following question given this paragraph: 24.2 Production of Electromagnetic Waves Electromagnetic waves are created by oscillating charges (which radiate whenever accelerated) and have the same frequency as the oscillation. Since the electric and magnetic fields in most electromagnetic waves are perpendicular to the direction in which the wave moves, it is ordinarily a transverse wave. The strengths of the electric and magnetic parts of the wave are related by. Q: What are electromagnetic waves created by? Choices: - Static Charges - gravitational charges - particle charges - oscillating charges A:
Ans: oscillating charges
(Q).
Answer the following question given this paragraph: Most primates have opposable thumbs. An opposable thumb can be brought into opposition with the other fingers of the same hand. This allows the hand to grasp and hold things. Q: Most members of what mammalian order possess opposable thumbs? Choices: - marsupials - rodents - amphibians - primates A:
(A).
primates
Ques:Answer the following question given this paragraph: The type of chemical signal a cell will send differs depending on the distance the message needs to go. For example, hormones , ions, and neurotransmitters are all types of signals that are sent depending on the distance the message needs to go. Endocrine signals are hormones, produced by endocrine organs. These signals travel through the blood stream to reach all parts of the body. Q: Hormones, ions, and neurotransmitters are all types of what? Choices: - nutrients - pathogens - proteins - chemical signals A:

Ans:chemical signals
Answer the following question given this paragraph: The first photosynthetic organisms were bacteria that lived in the water. So, where did plants come from? Evidence shows that plants evolved from freshwater green algae, a protist ( Figure below ). The similarities between green algae and plants is one piece of evidence. They both have cellulose in their cell walls, and they share many of the same chemicals that give them color. So what separates green algae from green plants?. Q: The first photosynthetic organisms were not plants, but types of what that lived in the water? Choices: - pathogens - fungi - algae - bacteria A:
bacteria
