Answer the following question given this paragraph: In binary fission, a cell splits in two. First, the large circular chromosome is copied. Then the cell divides to form two new daughter cells. Each has a copy of the parent cell's chromosome. Q: In binary fission how many times does a cell split? Choices: - four - one - six - two A:
two

Answer the following question given this paragraph: Matter typically exists in one of three states: solid, liquid, or gas. The state of a given substance is a physical property. Some substances exist as gases at room temperature (such as oxygen and carbon dioxide), while others (like water and mercury metal) exist as liquids. Most metals exist as solids at room temperature. All substances can exist in any of these three states. Q: Most metals exist in which form at room temperature? Choices: - gases - liquids - oils - solids A:
(Answer)
solids
Ques: Answer the following question given this paragraph: Cells may be small in size, but they are extremely important to life. Like all other living things, you are made of cells. Cells are the basis of life, and without cells, life as we know it would not exist. You will learn more about these amazing building blocks of life when you read this chapter. Q: What basic structures are called the building blocks of life and comprise all living things? Choices: - pigments - seeds - lipids - cells A:
Ans: cells
(Q).
Answer the following question given this paragraph: cell depletion, organ system failure, and impaired tissue injury responses. Telomerase reactivation in these mice caused extension of telomeres, reduced DNA damage, reversed neurodegeneration, and improved the function of the testes, spleen, and intestines. Thus, telomere reactivation may have potential for treating age-related diseases in humans. Cancer is characterized by uncontrolled cell division of abnormal cells. The cells accumulate mutations, proliferate uncontrollably, and can migrate to different parts of the body through a process called metastasis. Scientists have observed that cancerous cells have considerably shortened telomeres and that telomerase is active in these cells. Interestingly, only after the telomeres were shortened in the cancer cells did the telomerase become active. If the action of telomerase in these cells can be inhibited by drugs during cancer therapy, then the cancerous cells could potentially be stopped from further division. Q: What is characterized by uncontrolled cell division of abnormal cells? Choices: - radiation - concussions - hepatitis - cancer A:
(A).
cancer
Ques:Answer the following question given this paragraph: The mouth and stomach are just two of the organs of the digestive system. Other digestive system organs are the esophagus, small intestine, and large intestine. Below, you can see that the digestive organs form a long tube ( Figure below ). In adults, this tube is about 30 feet long! At one end of the tube is the mouth. At the other end is the anus. Food enters the mouth and then passes through the rest of the digestive system. Food waste leaves the body through the anus. Q: The mouth, stomach, esophagus, small intestine, and large intestine are all part of what organ system? Choices: - muscular - respiratory - lymphatic - digestive A:

Ans:digestive
Ques: Answer the following question given this paragraph: The only completely effective way to prevent infection with STIs is to avoid sexual contact and other risky behaviors. Using condoms can lower the risk of becoming infected with STIs during some types of sexual activity. However, condoms are not foolproof. Pathogens may be present on areas of the body not covered by condoms. Condoms can also break or be used incorrectly. Q: What is the only way to completely avoid stis? Choices: - cover your mouth - oral sex - contraceptive use - avoid sexual contact A:
Ans:
avoid sexual contact
