Q: Einstein developed a theory about how electromagnetic radiation can behave as both a wave and what else? Read this paragraph and choose the correct option from the provided answers: In 1905, the physicist Albert Einstein developed a new theory about electromagnetic radiation. The theory is often called the wave-particle theory . It explains how electromagnetic radiation can behave as both a wave and a particle. Einstein argued that when an electron returns to a lower energy level and gives off electromagnetic energy, the energy is released as a discrete "packet" of energy. We now call such a packet of energy a photon . According to Einstein, a photon resembles a particle but moves like a wave. You can see this in the Figure below . The theory posits that waves of photons traveling through space or matter make up electromagnetic radiation. Choices: - energy - bacteria - sound - particle A:
(Answer)
particle

Ques: Q: Amino acids broken down by metabolic process are mostly recycled into new what? Read this paragraph and choose the correct option from the provided answers: Connections of Proteins to Glucose Metabolism Proteins are broken down by a variety of enzymes in cells. Most of the time, amino acids are recycled into new proteins. If there are excess amino acids, however, or if the body is in a state of famine, some amino acids will be shunted into pathways of glucose catabolism. Each amino acid must have its amino group removed prior to entry into these pathways. The amino group is converted into ammonia. In mammals, the liver synthesizes urea from two ammonia molecules and a carbon dioxide molecule. Thus, urea is the principal waste product in mammals from the nitrogen originating in amino acids, and it leaves the body in urine. Choices: - lipids - hormones - enzymes - proteins A:
Ans: proteins

(Q).
Q: The e. coli chromosome, like many other bacterial chromosomes, is what shape? Read this paragraph and choose the correct option from the provided answers: Choices: - oval - square - triangular - circular A:
(A).
circular

Ques:Q: What type of device uses electromagnetic induction to change the voltage of electric current? Read this paragraph and choose the correct option from the provided answers: An electric transformer is a device that uses electromagnetic induction to change the voltage of electric current. Electromagnetic induction is the process of generating current with a magnetic field. It occurs when a magnetic field and electric conductor, such as a coil of wire, move relative to one another. A transformer may either increase or decrease voltage. You can see the basic components of an electric transformer in the Figure below . For an animation showing how a transformer works, go to this URL: http://www. youtube. com/watch?v=VucsoEhB0NA . Choices: - radioactive transformer - hot transformer - mechanical transformer - electronic transformer A:

Ans:electronic transformer

Q: Which division of the autonomic nervous system controls processes like digestion, heartbeat, and breathing? Read this paragraph and choose the correct option from the provided answers: The parasympathetic division controls internal organs and glands during the rest of the time. It controls processes like digestion, heartbeat, and breathing when there is not an emergency. Choices: - endocrine - synaptic - dopaminergic - parasympathetic A:
parasympathetic
