The animal which uses sounds as its ‘eyes’ is - |
| A. | Dog |
| B. | Cat |
| C. | Snake |
| D. | Bat |
| Answer» D. Bat | |
|
Explanation: Bat echolocation is a perceptual system where ultrasonic sounds are emitted specifically to produce echoes. By comparing the outgoing pulse with the returning echoes, the brain and auditory nervous system can produce detailed images of the bat's surroundings. This allows bats to detect, localize and even classify their prey in complete darkness. At 130 decibels in intensity, bat calls are some of the most intense, airborne animal sounds. |

|
Explanation: Red Blood cells contain haemoglobin which is what the oxygen bindswith to form oxyhaemoglobin which is then transported to the different cells around the body. Oxygen bonds with the haemoglobin when it is at high partial pressure and then is released when there is a lower partial pressure of oxygen. At high altitudes there is lower atmospheric pressure of oxygen. This means that the current number of red blood cells in the body cannot meet the cells demands for oxygen. |

What are the blood corpuscles that help to build up resistance against diseases? |
| A. | Leucocytes |
| B. | Monocytes |
| C. | Neutrophils |
| D. | Lymphoctyes |
| Answer» A. Leucocytes | |
|
Explanation: White blood cells, or leukocytes, are cells of the immune system involved in defending the body against both infectious disease and foreign materials. Five different and diverse types of leukocytes exist, but they are all produced and derived from a multipotent cell in the bone marrow known as a hematopoietic stem cell. They live for about three to four days in the average human body. Leukocytes are found throughout the body, including the blood and lymphatic system. |

Which is the gland that holds the body's thermostat? |
| A. | Pineal |
| B. | Pituitary |
| C. | Thyroid |
| D. | Hypothalamus |
| Answer» D. Hypothalamus | |
|
Explanation: The body keeps its core temperature constant at about 37 C by physiological adjustments controlled by the hypothalamus (Thermostat Center) where there are neurons sensitive to changes in skin and blood temperatures. The temperature-regulating centers are found in the Preoptic Area (the anteriorportion of the hypothalamus). This area receives input from temperature receptors in the skin and mucous membranes (Peripheral Thermoreceptors) and from internal structures(Central Thermoreceptors), which include the hypothalamus itself. |

Pathogenic bacteria secrete - |
| A. | Antigens |
| B. | Antibodies |
| C. | Hormones |
| D. | Interferons |
| Answer» A. Antigens | |
|
Explanation: Pathogenic bacteria secrete various virulence factors, including toxins, lipases and pro-teases that allow them to infect, breakdown and colonize host tissue. Among various modes of action that the pathogenic bacteria use to damage the host, pore formation (by pore forming toxins (PFTs)) and lipid hydrolysis (by phospholipases) modes are common in damaging the eukaryotic cell membrane. PFTs in their monomeric form are extracellular diffusible and able to form hydrophilic pores in cell membrane while phospholipases cleaves and hydrolyzes the ester bonds of most phospholipids in cell membrane. |

Which wood will become useless soon after exposing in the open air - |
| A. | Soft wood. |
| B. | Fibrous wood |
| C. | Wet wood |
| D. | Hard wood |
| Answer» C. Wet wood | |

However, it does not mean that the other 99.9 percent is a "vast untapped reservoir" awaiting man's exploitation. All biological systems, including crops, follow the second law of thermodynamics when solar energy to high-energy form) is converted into chemical energy. Plants utilize this chemical energy in the process of building their own tissue. Some of the energy being changed from light to chemical energy is lost as heat that dissipates into the surrounding environment. |

If the radius of blood vessels of a person decreases his/her blood pressure will |
| A. | increase |
| B. | decrease |
| C. | remain unaffected |
| D. | increase for males and decrease for females |
| Answer» A. increase | |
|
Explanation: An obese person has a greatly increased number of blood vessels because of the amount of adipose tissue that must be serviced. As a result, the total length of his or her vascular tree is greatly increased and this person tends to have a higher blood pressure because of the greater resistance to blood flow. Resistance is inversely proportional to the fourth power of the radius of the blood vessel. In other words, the smaller the diameter of the vessel, the greater the resistance it offers to blood flow. |
