Answer the following question given this paragraph: In 1858, after using microscopes much better than Hooke's first microscope, Rudolf Virchow developed the hypothesis that cells only come from other cells. For example, bacteria, which are single-celled organisms, divide in half (after they grow some) to make new bacteria. In the same way, your body makes new cells by dividing the cells you already have. In all cases, cells only come from cells that have existed before. This idea led to the development of one of the most important theories in biology, the cell theory . Q: Rudolf virchow developed the hypothesis that cells only come from other cells in what year? Choices: - 1898 - 1868 - 1848 - 1858 A:
1858

Answer the following question given this paragraph: How do you cool down a glass of room-temperature cola? You probably add ice cubes to it, as in the Figure below . You might think that the ice cools down the cola, but in fact, it works the other way around. The warm cola heats up the ice. Thermal energy from the warm cola is transferred to the much colder ice, causing it to melt. The cola loses thermal energy in the process, so its temperature falls. Q: What type of energy from a warm cola results in melting when it is transferred to the much colder ice? Choices: - protective energy - gaseous energy - cyclic energy - thermal energy A:
(Answer)
thermal energy
Ques: Answer the following question given this paragraph: Deductive reasoning means making a specific statement based on a general principle. Q: Making a specific statement based on a general principle is the definition of what type of reasoning? Choices: - inductive - inference - transitive - deductive A:
Ans: deductive

Answer the following question given this paragraph: Skeletal muscle tissue forms skeletal muscles, which attach to bones and sometimes the skin and control locomotion and any other movement that can be consciously controlled. Because it can be controlled intentionally, skeletal muscle is also called voluntary muscle. When viewed under a microscope, skeletal muscle tissue has a striped or striated appearance. This appearance results from the arrangement of the proteins inside the cell that are responsible for contraction. The cells of skeletal muscle are long and tapered and have multiple nuclei on the periphery of each cell. Smooth muscle tissue occurs in the walls of hollow organs such as the intestines, stomach, and urinary bladder, and around passages such as in the respiratory tract and blood vessels. Smooth muscle has no striations, is not under voluntary control, and is called involuntary muscle. Smooth muscle cells have a single nucleus. Cardiac muscle tissue is only found in the heart. The contractions of cardiac muscle tissue pump blood throughout the body and maintain blood pressure. Like skeletal muscle, cardiac muscle is striated, but unlike skeletal muscle, cardiac muscle cannot be consciously controlled and is called involuntary muscle. The cells of cardiac muscle tissue are connected to each other through intercalated disks and usually have just one nucleus per cell. Q: Because it can be controlled intentionally, skeletal muscle is also called what type of muscle? Choices: - automatic - necessary - involuntary - voluntary A:
(A).
voluntary
Ques:Answer the following question given this paragraph: Sedimentary rocks are formed in horizontal layers. This is magnificently displayed around the southwestern United States. The arid climate allows rock layers to be well exposed ( Figure below ). The lowest layers are the oldest and the higher layers are younger. Q: Sedimentary rocks form in what kind of layers? Choices: - stacked - magnetic - vertical - horizontal A:

Ans:horizontal
Ques:Answer the following question given this paragraph: Q: Veins subdivide repeatedly and branch throughout what? Choices: - periosteum - epidermis - stroma - mesophyll A:

Ans:
mesophyll
