Animals, such as mammals and birds, that maintain a constant body temperature regardless of the temperature of the surroundings are called warm blooded. It describes animal species which have a relatively higher blood temperature, and maintain thermal homeostasis primarily through internal metabolic processes. Examples of warm blooded animals include: mammals, cats, dogs, humans, giraffes, elephants, bears, beavers, chickens, monkeys, whales, deer, cows, wolf, birds, etc. Cold Blooded animals use external means to control their body temperature. These ectothermic methods include basking in the sun, hiding in the shade, changes in metabolic rate. Some animals’ body temperature even change with there environment. Animals that fall into this category are: fish, insects, spiders, frogs, snakes, alligators, toads, turtles, sharks, etc.

Correct Option: A

Cholesterol is defined as a waxy alcohol, fat-like substance that occurs naturally in all areas of the human body. 100-200 mg/dL is considered as normal for the human beings. However it must be noted that total cholesterol counts below 180 mg/dl increase the risk for hemorrhagic stroke; below 180 cholesterol levels are inversely associated with risk. Total cholesterol counts above 200 mg/dl may be normal and healthy for some people, as the ratio of LDL to HDL cholesterol is considered a more important factor in prediction of disease risk. Women tend to benefit more from an increase in HDL rather than lowering of LDL, whereas men tend to benefit from a decrease in LDL when cholesterol abnormalities or heart disease risk factors exist.

Correct Option: D

DNA profiling (genetic fingerprinting) is a technique employed by forensic scientists to assist in the identification of individuals by their respective DNA profiles. DNA profiles are encrypted sets of numbers that reflect a person’s DNA makeup, which can also be used as the person’s identifier. DNA profiling should not be confused with full genome sequencing. It is used in, for example, parental testing and criminal investigation.

Cell division is the process by which cells produce new cells. Cell division differs in prokaryotes (bacteria) and eukaryotes (protists, fungi, plants, & animals). Some tissues must be repaired often such as the lining of gut, white blood cells, skin cells with a short lifespan. Other cells do not divide at all after birth such as muscle & nerve.
