Answer the following question given this paragraph: Summary Superconductors are solids that at low temperatures exhibit zero resistance to the flow of electrical current, a phenomenon known as superconductivity. The temperature at which the electrical resistance of a substance drops to zero is itssuperconducting transition temperature (Tc). Superconductors also expel a magnetic field from their interior, a phenomenon known as the Meissner effect. Superconductivity can be explained by the BCS theory, which says that electrons are able to travel through a solid with no resistance because they couple to form pairs of electrons (Cooper pairs). Hightemperature superconductors haveTc values greater than 30 K. Q: Superconductors expel a magnetic field from their interior. what is this phenomenon known as? Choices: - weissenberg effect - eibner effect - lauer effect - meissner effect A:
meissner effect

Q: Hypertension, or high blood pressure, can increase the risk of what? Choices: - bone disease - physiological disease - abnormal disease - cardiovascular disease A:
(Answer)
cardiovascular disease

Specialized cardiac muscle cells trigger the contractions. Q: The heart contracts rhythmically to pump what to the lungs and the rest of the body? Choices: - Bile - Cerumen - Chyle - blood A:

Ques:Answer the following question given this paragraph: Modern nonvascular plants are called bryophytes. There are about 17,000 bryophyte species. They include liverworts, hornworts, and mosses. Mosses are the most numerous group of bryophytes. You can see an example of moss in Figure below . Like the moss in the figure, most bryophytes are small. They lack not only vascular tissues. They also lack true roots, leaves, seeds, and flowers. Bryophytes live in moist habitats. Without the adaptations of vascular plants, bryophytes are not very good at absorbing water. They also need water to reproduce. Q: What is the term for plants that lack vascular tissues, roots, leaves, seeds, and flowers? Choices: - chloroplasts - primates - conifers - bryophytes A:

Ans:bryophytes
Ques: Answer the following question given this paragraph: Mutagenesis may occur spontaneously or be induced. A spontaneous mutation can just happen. These mutations are not caused by an environmental factor, but occur during normal cellular processes. A spontaneous mutation may be due to a mistake during DNA replication or transcription. Mutations may also occur during mitosis and meiosis. A mutation caused by an environmental factor, or mutagen , is known as an induced mutation . Typical mutagens include chemicals, like those inhaled while smoking, and radiation, such as X-rays, ultraviolet light, and nuclear radiation. Table below lists some spontaneous mutations that are common. Q: Induced mutations are caused by environmental factors. what term is used to describe a mutation that has no environmental cause? Choices: - cancerous mutation - evident mutation - numerous mutation - spontaneous mutation A:
Ans:
spontaneous mutation
