When we inhale and exhale a process known as breathing takes place. During breathing ; gaseous exchange , that is ; excretion of carbon dioxide and inhalation of oxygen takes place.
Remark : - Dont confuse respiration and breathing. They are different processes. Breathing simply means inhalation of oxygen and exhalation of carbon dioxide ; while respiration means involves breakdown of food and it is a deeper process.
Answer:
i think a. is correct answer (:
hope its help for u
The carbon 14 left from this animal is 3 grams of 24 grams which is: 3g/24g= 1/8 times of its original mass. Then, the age of the animal fossil would be:
final weight= initial weight * (1/2) ^ time/half-live
1/8 initial weight = initial weight * (1/2) ^ time/half-live
log2 1/8= log2 (1/2) ^ time/half-live
-3= -time/half-live
time= -3 * -(half-live)
time= 3 half-live
If the half-live is 5730 years, the age would be: 3* 5730= 17.190 years.
The statement saying, "<span>A demonstration speech typically revolves around a process or sequence of events</span>." is true. As the name suggests, a demonstration speech aims to inform the audience primarily through demonstrating the steps involved in accomplishing a certain task. It is then necessary that the process is done chronologically and in detail.
