Ques: Answer the following question given this paragraph: Introduction Genetics is the study of heredity. Johann Gregor Mendel set the framework for genetics long before chromosomes or genes had been identified, at a time when meiosis was not well understood. Mendel selected a simple biological system and conducted methodical, quantitative analyses using large sample sizes. Because of Mendel's work, the fundamental principles of heredity were revealed. We now know that genes, carried on chromosomes, are the basic functional units of heredity with the ability to be replicated, expressed, or mutated. Today, the postulates put forth by Mendel form the basis of classical, or Mendelian, genetics. Not all genes are transmitted from parents to offspring according to Mendelian genetics, but Mendel's experiments serve as an excellent starting point for thinking about inheritance. Q: Introduction genetics is the study of what? Choices: - biology - variability - obesity - heredity A:
Ans: heredity
(Q).
Answer the following question given this paragraph: Some regions of the electron cloud are denser than others. The denser regions are areas where electrons are most likely to be. These regions are called orbitals . Each orbital has a maximum of just two electrons. Different energy levels in the cloud have different numbers of orbitals. Therefore, different energy levels have different maximum numbers of electrons. Table below lists the number of orbitals and electrons for the first four energy levels. Energy levels farther from the nucleus have more orbitals. Therefore, these levels can hold more electrons. Q: The denser regions of the electron cloud are called what? Choices: - cores - lattices - isotopes - orbitals A:
(A).
orbitals
Ques:Answer the following question given this paragraph: The second equation is equivalent to the first. Voltage is not the same as energy. Voltage is the energy per unit charge. Thus a motorcycle battery and a car battery can both have the same voltage (more precisely, the same potential difference between battery terminals), yet one stores much more energy than the other since PE = qV . The car battery can move more charge than the motorcycle battery, although both are 12 V batteries. Q: What term is not the same as energy, but means the energy per unit charge? Choices: - frequency - speed - mass - voltage A:

Ans:voltage
Ques: Answer the following question given this paragraph: This super fast train can obviously reach great speeds. And there's a lot of technology that helps this train go fast. Speaking of helping things go fast brings us to enzymes. Life could not exist without enzymes. Essentially, enzymes are biological catalysts that speed up biochemical reactions. Q: What are biological catalysts that speeds up biochemical reactions? Choices: - carbohydrates - hormones - proteins - enzymes A:
Ans:
enzymes
