Q: What is the major cause of chronic respiratory disease as well as cardiovascular disease and cancer? Read this paragraph and choose the correct option from the provided answers: Smoking is the major cause of chronic respiratory disease as well as cardiovascular disease and cancer. Exposure to tobacco smoke by smoking or by breathing air that contains tobacco smoke is the leading cause of preventable death in the United States. Regular smokers die about 10 years earlier than nonsmokers do. The Centers for Disease Control and Prevention (CDC) describes tobacco use as "the single most important preventable risk to human health in developed countries and an important cause of [early] death worldwide. " Simply stated: Stopping smoking can prevent many respiratory diseases. Choices: - drinking - exercise - diet - smoking A:
smoking

Q: What is the study of the similarities and differences in the embryos of different species? Read this paragraph and choose the correct option from the provided answers: Comparative embryology is the study of the similarities and differences in the embryos of different species. Similarities in embryos are evidence of common ancestry. All vertebrate embryos, for example, have gill slits and tails. Most vertebrates, except for fish, lose their gill slits by adulthood. Some of them also lose their tail. In humans, the tail is reduced to the tail bone. Thus, similarities organisms share as embryos may be gone by adulthood. This is why it is valuable to compare organisms in the embryonic stage. See http://www. pbs. org/wgbh/evolution/library/04/2/pdf/l_042_03. pdf for additional information and a comparative diagram of human, monkey, pig, chicken and salamander embryos. Choices: - example embryology - prenatal biology - diversified embryology - comparative embryology A:
(Answer)
comparative embryology

Ques: Q: What is the most common way to classify stars? Read this paragraph and choose the correct option from the provided answers: The most common way of classifying stars is by color as shown, in Table below . Each class of star is given a letter, a color, and a range of temperatures. The letters don't match the color names because stars were first grouped as A through O. It wasn't until later that their order was corrected to go by increasing temperature. When you try to remember the order, you can use this phrase: "Oh Be A Fine Good Kid, Man. ". Choices: - by age - by distance - by size - by color A:
Ans: by color

Ques:Q: A red blood cell will swell and burst when placed in a? Read this paragraph and choose the correct option from the provided answers: A cell that does not have a rigid cell wall, such as a red blood cell, will swell and lyse (burst) when placed in a hypotonic solution. Cells with a cell wall will swell when placed in a hypotonic solution, but once the cell is turgid (firm), the tough cell wall prevents any more water from entering the cell. When placed in a hypertonic solution, a cell without a cell wall will lose water to the environment, shrivel, and probably die. In a hypertonic solution, a cell with a cell wall will lose water too. The plasma membrane pulls away from the cell wall as it shrivels, a process called plasmolysis . Animal cells tend to do best in an isotonic environment, plant cells tend to do best in a hypotonic environment. This is demonstrated in Figure below . Choices: - acidic solution - exothermic solution - dissolved solution - hypotonic solution A:

Ans:hypotonic solution
