Answer the following question given this paragraph: Infections with the human papillomavirus (HPV) are very common. HPV may cause genital warts , which are small, rough growths on the genitals. It may also cause cancer of the cervix in females. A simple test, called a Pap test , can detect cervical cancer . If the cancer is detected early, it usually can be cured with surgery. There is also a vaccine , GARDASIL, to prevent infection with HPV. The vaccine is recommended for females aged 11 to 26 years. Q: What is the vaccine to prevent infection of hpv? Choices: - cervical - HIV - herpes - gardasil A:
gardasil

(Q).
Answer the following question given this paragraph: When a sperm penetrates the egg, it triggers the egg to complete meiosis. The sperm also undergoes changes. Its tail falls off, and its nucleus fuses with the nucleus of the egg. The resulting cell, called a zygote , contains all the chromosomes needed for a new human organism. Half the chromosomes come from the egg and half from the sperm. Q: What is the name of the cell that results when a sperm nucleus fuses with a egg nucleus? Choices: - t cell - a cytoplasm - a filament - a zygote A:
(A).
a zygote
Ques:Answer the following question given this paragraph: The central vacuole maintains turgor pressure against the cell wall. Q: The central vacuole maintains turgor pressure against what? Choices: - the cell move - the cell multiplication - the cell addition - the cell wall A:

Ans:the cell wall
Ques: Answer the following question given this paragraph: The sum of the calculated atomic radii of sodium and chlorine atoms is 253 pm. The sodium cation is significantly smaller than a neutral sodium atom (102 versus 154 pm), due to the loss of the single electron in the 3s orbital. Conversely, the chloride ion is much larger than a neutral chlorine atom (181 versus 99 pm), because the added electron results in greatly increased electronelectron repulsions within the filled n = 3 principal shell. Thus, transferring an electron from sodium to chlorine decreases the radius of sodium by about 50%, but causes the radius of chlorine to almost double. The net effect is that the distance between a sodium ion and a chloride ion in NaCl is greaterthan the sum of the atomic radii of the neutral atoms. Q: Transferring what from sodium to chlorine decreases the radius of sodium by about 50%? Choices: - quark - proton - neutron - electron A:
Ans:
electron
