if they are both negative, add like they are positive numbers, but just add the negative sign.
No. Inventory and engineering work need negative numbers to measure. Also, how can we measure the temperature if it's freezing cold without negative numbers? Integers are needed for calculations and measurements in this world.
The absolute value of any negative number is equal to its positive equivalent, that is, the number without its negative sign. In this instance, abs(-54) is equal to 54.
No. A number without a sign before it is always taken to be positive.
The hypothalamus is responsible for the regulation of temperature in organisms. It is important because temperature directly affects vital biochemical processes within the body. Without a regulating mechanism, the organism will die.
yep... using nanofibres... researchers had found that wound will be healed if there is no infection on it. i.e., pathogens infects the wound and does not let to heal. They found that gram negative organisms are pathogens which is reason for infections. So, they made the bandage with nanofibres which carries positive charges which will attract the gram negative organisms which carries negative charges on their surface, and protect the wound from the gram negative organisms. This will lead to healing.
If you stick your hand in a fire, it will hurt. That is negative feedback. Pain receptors are a very important survival adaptation. Without them, living things would be extremely damage-prone.
It depends on what sense your using the word negative. However, if everything were negative, you would never know what positive was. If everything were positive, you would never know what negative was. Its all about learning proper balance, how one affects the other, and how we can use this information for appropriate growth. Growth cannot be achieved without the knowledge and wisdom of both.
The us invasion of Iraq without UN approval or support has given negative repercussions for our country all over the world.
Prokaryotes are the one cell organisms without organelles.
No.
The temperature of water affects living organisms because they have to adjust to one temperature to survive. For example; some fish live only in cold water, and then oneday if the water temperature suddenly rose and became warm/hot, this would pose a problem for the fish!
Reproducing.
Complex organisms need cells that perform many different functions. Complex organisms are capable of a lot of different things, and that variety needs to be supported on the cellular level. Without them, complex organisms cannot perform different functions.
soil organisms are important because without the organisms there'd be no plants
