[12] Pregnant women usually become deficient in -
A.
Sodium and Calcium
B.
Iron and Sodium
C.
Calcium and Iron
D.
Magnesium and Iron
Ans:
Calcium and Iron
Explanation :
When a woman becomes pregnant her body undergoes many physiological changes. Her hormone levels change not only to support the pregnancy but also to help redirect nutrients to support the nutritional demands of the developing baby. During pregnancy, a woman’s blood volume increases 35 percent to 40 percent. Red blood cells contain the protein hemoglobin, which requires the mineral iron. Hemoglobin carries the oxygen to the cells throughout the mother and baby, making iron an important nutrient. Because the plasma volume increases by up to 50 percent but the red blood cells mass increases by only 15 percent to 20 percent, the risk of developing iron-deficiency anemia increases during pregnancy. Calcium needs increase during pregnancy to support the growth and development of the baby’s bones and teeth. Failing to consume the recommended 1,200 mg of calcium per day can cause body to pull calcium from the pregnant woman’s bones to use for the baby.

In the past 60 years, antibiotics have been critical in the fight against infectious disease caused by bacteria and other microbes. In 1946, penicillin became generally available for treatment of bacterial infections, especially those caused by staphylococci and streptococci. Initially, the antibiotic was effective against all sorts of infections caused by these two Gram-positive bacteria. Penicillin had unbelievable ability to kill these bacterial pathogens without harming the host that harbored them.
[16] Which part of human body is first highly affected by nuclear radition?
A.
Eyes
B.
Lungs
C.
Skin
D.
Bone Marrow
Ans:
Skin
Explanation :
When molten nuclear fuel melts through a nuclear power plant’s barriers, it causes a serious radiation leak. The radioactive materials will seep out to the surrounding environment, and into the air. Once in the upper atmosphere, high winds and jet streams could carry the dust to all places, and dropping radiation on everything, causing radiation poisoning. Radiation can penetrate deep inside the human body, and into the cells. Certain body parts are more specifically affected by exposure to different types of radiation sources. The areas of skin exposed to radiation will appear like severe sunburn, then sores may form, and skin infection may develop.

[23] Cell or tissue death within a living body is called as -
A.
Neutrophilia
B.
Neplarosis
C.
Necrosis
D.
Neoplasia
Ans:
Necrosis
Explanation :
Necrosis is death of body tissue. It occurs when there is not enough blood flowing to the tissue, whether from injury, radiation, or chemicals. Necrosis is riot reversible. When substantial areas of tissue die due to a lack of blood supply, the condition is called gangrene. Necrosis is caused by factors external to the cell or tissue, such as infection, toxins, or trauma that result unregulated digestion of cell components.
[24] Insufficient blood supply in human body is referred as -
A.
Ischemia
B.
Hyperemia
C.
Hemostasia
D.
Hemorrhage
Ans:
Ischemia
Explanation :
In medicine, ischemia denotes a restriction or thinning or to make or grow thin/lean, haema blood) is a restriction in blood supply to tissues, causing a shortage of oxygen and glucose needed for cellular metabolism (to keep tissue alive). Is Hernia is generally caused by problems with blood vessels, with resultant damage to or dysfunction of tissue. It also means local anemia in a given part of a body sometimes resulting from congestion (such as vasoconstriction, thrombosis or embolism).
[25] The only snake that builds a nest is:
A.
Chain viper
B.
King Cobra

Explanation :
Trace elements play important role in Insulin metabolism. The relationship between diabetes, insulin and zinc (Zn) is complex with no clear cause and effect relationships. Several of the complications of diabetes may be related to increased intracellular oxidants and free radicals associated with decreases in intracellular Zn and in Zn dependent antioxidant enzymes.
[12] Pregnant women usually become deficient in -
A.
Sodium and Calcium
B.
Iron and Sodium
C.
Calcium and Iron
D.
Magnesium and Iron
Ans:
Calcium and Iron
Explanation :
When a woman becomes pregnant her body undergoes many physiological changes. Her hormone levels change not only to support the pregnancy but also to help redirect nutrients to support the nutritional demands of the developing baby. During pregnancy, a woman’s blood volume increases 35 percent to 40 percent. Red blood cells contain the protein hemoglobin, which requires the mineral iron. Hemoglobin carries the oxygen to the cells throughout the mother and baby, making iron an important nutrient. Because the plasma volume increases by up to 50 percent but the red blood cells mass increases by only 15 percent to 20 percent, the risk of developing iron-deficiency anemia increases during pregnancy. Calcium needs increase during pregnancy to support the growth and development of the baby’s bones and teeth. Failing to consume the recommended 1,200 mg of calcium per day can cause body to pull calcium from the pregnant woman’s bones to use for the baby.
[13] Which components of light are absorbed by chlorophyll?
A.
Violet and red
B.
