Which feature of living organisms is the least important for individual survival? (A) Nutrition, (B) excretion, (C) reproduction, (D) sensitivity, or (E) respiration. Several life processes are essential for all living organisms to carry out to survive. First, they must be sensitive to their surrounding environment and changes within their internal environment so that they can respond appropriately. For example, if it gets too hot, an animal must be sensitive to that in order to recognize the need to move to cooler ground or take in enough water. Nutrition is also essential to life, as individuals must be able to obtain adequate fuel for their cells to conduct cellular respiration, as well as for growth and repair. Cellular respiration itself is essential, as that is the only way that cells will get the energy they need to continue life processes. Without cellular respiration happening, cells will simply die. And then, as well as taking in food, organisms must also be able to excrete waste. This prevents potentially toxic waste products from building up within the body, which could lead to damage or even death. Reproduction is another process common to all living species. While it is essential to the survival of the species that it persists for successive generations, it is not essential to an individual’s survival, as the failure to reproduce does not usually change the life expectancy of the individual. In fact, in some cases, reproduction can lower an individual’s life span. For example, some octopus die soon after mating and reproducing and will live longer if they don’t reproduce. If we look at the options provided for this question, we see that the only choice that is not essential for survival is reproduction. So the correct answer is (C). The least important feature of living organisms for individual survival is reproduction.

A Go Bag is a great thing to have on hand in case you ever need to evacuate in an emergency. To make one, select a sturdy, heavy-duty duffel bag or suitcase. Pack it with a 3-day supply of non-perishable food items, such as peanut butter, granola bars, and canned tuna. Include 1 gallon (3.8 L) of potable water per person, or a portable water filtration system. Pack clothes that are appropriate for the weather in your area, such as warm socks, walking shoes, and a jacket. If you think you might be sleeping outdoors, include a mylar blanket or sleeping bag and a small tent if you have room. Don’t forget to pack practical tools, such as a flashlight, emergency radio, and solar battery charger, as well as a first aid kit, hygiene products, and any medications you might need. Finally, put copies of any important documents you might need, such as your ID and insurance information, in water-proof plastic bags.
