body heat

Although we all come from different races, and different parts of the world our bodies tend to react the same to the weather and changing climates. for example lets say one was living in Alaska for 2 years and then went to go visit New York during winter; their body would be much more adjusted to the cold than someone who is coming from living in constant heat. heat for one can be extremely harmful; over heating is one of them, causing the body to vomit and sweat immensely in order to keep your body cool. When your body is over heating the hypothalamus sends signals to your sweat glads to produce more sweat so you cool down when the water evaporates off your skin, causing your body to cool off.

 short term adaptation -  of over heating would be sweating, sweating allows your body to releases beads of water that evaporate off the skin and temporarily cool you down.

cultural adaptions - when living in extreme weathers of heat, we've learned its not the best decision to go out in a snow jacket and snow boots. we all tend to wear lighter, more breathe able clothing such as tank tops and shorts to allow the body to release extra heat.

faculative adaptation - the less body hair one has, the quicker they'd be able to shed the excess body heat.

developmental adaptations - skin color is one of the factors, people living in hotter climates have darker skin from the sun. also body size ties with the amount of body heat one retains, a leaner more fit body holds less heat compared to a fattier body structure.

i believe the benefits of studying human variations across environmental inclines helps us all out because it opens up our eyes that it is based on genetics, not off of ones skin color due to the fact that it fluctuates and also not particular regions because people

language

part 1:

in this half of the assignment we where asked to hold a conversation without using any form of spoken language. but we where allowed to use our hands as gestures and facial expressions in attempt to get our point across. in my experiment i tried holding a conversation with my brother on what to eat for dinner. this was extremely hard because i wasn't able to simply tell him  what i wanted to eat and being hungry didn't help things at all. i got very frustrated because i was grabbing ingredients and trying to make him understand that i wanted a salad tonight but he just got fed up after 15 minutes and started ignoring me and told me to feed myself when the experiment was over. needless to say he didn't like the fact that i wasn't able to tell him what i was hungry for just by speaking.

part 2:

the second half of this assignment was to hold another conversation but this time we couldn't use any form of bodily communication but we could speak. i asked my brother to put away my sweater in a certain spot in my closet and i couldn't point or show any form of bodily expression, this got her annoyed very quickly. i had to stop myself from pointing, or fluctuating my voice or ever make a bratty face because i too was getting annoyed with myself. after 15 min the sweater still didn't reach its destination and i had an annoyed sibling. after conducting this experiment i asked her how he felt he said that he surprisingly got more annoyed when i wasn't able to show body gestures when trying to communicate, he said i resembled a robot and it stripped me of what makes us human. he would much rather have me be silent but still be able to point and show facial expression. over all i really do feel like being able to express ourselves with our body's,hands and faces are far more effective then just speaking aloud.
